I really appreciate your communication style and how you articulate the good and the bad. Your experience shows. All the best with the water/fuel and electrical draw concerns.
The trailer light pulsing you are getting is an anti theft setting. When locked, the truck puts a minimal amperage out the 7-way to see if the trailer is still there. If someone were to attempt to steal the trailer and disconnect the 7-way, the vehicle alarm would activate. I believe there is a setting in the main screen to turn it on or off. LED lighting doesn’t require much output so it can cause flickering. Standard halogens don’t have the same issue. I have trailers with both so I had to do some forum digging to figure this out.
Came here to say the same. It had me scratching my head on my trailer when it had never done it before and then I remembered I had turned that feature on recently.
Hey Howard, nice video. Next time you get a CEL, just call onstar. They will email a copy of the diagnosis with codes for the records. Also for the multipro tailgate, If you hold down the inner tailgate button for 4sec's, the computer will disable the button so that we can prevent dropping it onto the hitch, accidentally. Don't ask how I came to know...
I picked up my first Chevy I’ve been driving Ford F150’s the last 10 years. Software issues, oil leaks, 10 speed tranny issues. Nothing super serious but frustrating. Decided to go to a HD for the same reasons you did. I wasn’t loyal to Ford and a my dealer gave me 10 K off MSRP on a 2500 Z71 LTZ Duramax with standard bed. Had to replace the brake controller as it would disconnect the brakes on my Rv. There’s a bulletin for that. I’ve experienced the same tail light issue on the trailer you mentioned with the lights and engine off, and I still get warnings about checking the turn signals if I idle in park duty a minute or two. The problem goes away after running the turn signals twice when the trailer is connected. Love the Duramax so far. It’s my first diesel. All in all, so far, so good for me too. I’ll say 95% satisfied.
The pulsing of the lights is to let you know that the alarm feature is active. If someone was to unplug your trailer and try to steal it, the truck alarm would go off.
I bought a new ‘22 Duramax 2500. Had a def heater burn out, had a leaky radiator and water pump replaced under warranty. 66000 km on the clock and seems solid now. I love these trucks they tow like there is nothing behind you. Hope yours gets sorted out.
I’ve had my 2024 Silverado 3500HD 6.6 gas for 4 months, 4000 miles. LT trim with Z71 Sport package. It’s been perfect so far (knock on wood). Very good truck for me.
Thanks for the vid! Maybe get a FASS filter or Air Dog system regarding bad fuel. Allot of transit transport guys like em where their filling at all kinds of diesel stations across the nation and not able to control where their fueling all the time.
Good update! Really appreciated your Flint, MI plant tour episode. My 2024 2500HD w/max tow w/12K miles now had the same early life phantom no-start w/emissions system error issue (removing the main battery’s comnections cleared it and hasnt repeated since). GM is clearing a few more bugs on this significant new electronics year as well... Mine’s had more 2 bulletin services for a tranny reprogramming (fixed a hard and erratic shift point near 50mph) and an intermittent trailer brake error (replaced a part in the rear trailer harness). Also had a bad Goodyear AllTrail tire (bead failure) so get the Michelins is my advice there! Also found a known issue w/my rear trailer’s bluetooth camera that pulsed on/off (fixed with a Furrion adapter for $45 that makes that pin in the trailer 7-pin constant 12v hot as GM decided to pulse the 12v current there for some reason). The tire issue stunk, but otherwise love the Duramax truck’s towing performance and interior comfort besides. Hope this helps folks.
I very much look forward to your follow up video. I am in the process of installing the GM camera to the rear of my 5th wheel. The install on the trailer is not difficult however the camera plug on the truck is the problem. The camera plug is located above the 7 pin plug on the bumper of the truck. The camera plug connection has to be relocated into the bed of the truck. My truck does the same light flickering when my 5th wheel is connected. Like you, I disconnect the trailer when parking overnight. I was told by the Dealership, the light flickering you are experiencing is the truck making sure your trailer is still connected. I do not have the lights flickering on my trailer with incandescent trailer lights. The flickering only happens on the trailers with LED lights. Excited to see your follow-up video. Hopefully you will get some answers.
I have the same vehicle with a short box and have a hard time parking it :-) That really ticks me off that they wouldn't relinquish the bottle to you and I can only imagine what they would've charged you to drain the tank.
Well of course the bottle is their property…. It’s literally THEIRS and they need to keep it to help another customer! ☺️ Time to change dealership Sir… Thank you for the update.
I would have demanded that the put the truck up on the rack again & pull another sample for me. If they would not do that then I know they are lying. I dislike car dealers as much as I dislike politicians!
Thanks for this update. Usually, brand-new truck owners will have to deal with the recalls, service issues, etc. Thats why I buy a used truck. So far, your truck is doing excellent. I still have my used 2018 Ram 3500 mega cab 50K miles no issues at least for now. Whenever in San Antonio look me up we can have some coffee and talk about our trucks and RV's.
Nice job Howard, it's great to hear everything about your new truck. Going down south to me is bringing a bucket of grain to a lower pasture for the Black Angus. I'm only 70, so I've got a while to go before I can do any traveling. Be safe.
I have the 2500 standard bed and I’m towing a 33’ Reflection. Like you said, it’s stress free towing! I learned the last time at the dealer that the invisible trailer camera changed and the $600 camera that people bought for their trucks 3 years ago won’t work on this one! I’m probably going to go with a Bluetooth one unless you end up convincing me otherwise…The camera system as it stands is incredible!
I have a 22 High Country SRW 3500 Long Bed. If you look at the hitch for Fifth Wheel/Goose neck on the long bed, it is centered over the rear axle, but on a short bed, which is only 10 inches shorter than the Long bed, the same hitch and or Puck system is about 4 inches behind the axle. There is a cross member in the way, so even an after market install would be difficult to center on the axle. My guess is they did this to prevent damage to the rear window/cab area while towing. The B & W Hitch for the Multi-Function tailgate really does the job. Although I would think GM should have come up with a solution for the issue by now, but my guess is if they did, there might be retro fixes involved that they don't want to deal with. As far as parking goes, the camera system is very helpful, I have found the easiest way to access the parking camera is to stop while entering the spot and momentarily shift to Reverse, then pull forward. Our Escalade has a touch screen button you can turn the parking camera on with.
The hitch problem is a simple fix by purchasing the right equipment. B&W makes a hitch specifically for the MultiPro application. Suprised to see that you would let that happen to your truck.
Thanks for the update. I have had a sensor issue for the emissions system - apparently a bad batch that was manufacturing GM. I look forward to your update over the camera as I am thinking of doing the same. Always appreciate the channel. I have not noticed the lights on my trailer when the truck is off.
My 2022 dually and now my 2024 3500 SRW do the LED light flicker. No issue and some have explained it already. My neighbor even commented when I had the rig parked out front over night :)
I enjoyed your comments. I had an intermittent light on my 2020 1500 AT4. Long story made short after several visits to the dealer that's 30 minutes away. They replaced the correct sensor in my transmission. It was a little disconcerting for the transmission to drop into L5 at highway speed and stay in L5 for maybe a day. No shifting in drive at all.
Greetings from Colorado! I have the same issue with my 2024 Silverado 3500 LWB. When the trailer is connected to the truck, the LED lights on the trailer flickers as you mentioned. I just called the dealership as soon as I saw this video. The dealership says, its normal. All its saying that the truck is connected to the trailer. The draw is so little that it will not run the battery down. As a precaution, I unhook the trailer plug when parked overnight. Best regards, Sikander
I appreciate your channel and both of your perspectives. I have a 22 gmc 3500. I thought about adding that trailering camera. But i also tow a fifthwheel and the camera plug in is down by the license plate/bumper. Its not in the bed where i plug in my fifthwheel. And i think if i jack-knifed my trailer the wiring for the camera would rip out....
On the pulsing brake light issue, I believe the parking brake sets electronically any time a trailer is attached. That might be why the brake lights pulse as it applies just enough current to keep it set. Just a guess, but I imagine that a trailer would have to be connected for a very long time to be a an issue especially with 2 batteries.
I have the same color 3500 LB, CC, SRW but a GMC SLT gasser. I've done the aux battery and trailer brake recalls/advisories. My manual says to change oil at 500 miles if you plan to heavy tow, so I did that. All 9 grease fittings were dry, and the rear differential was a quart low. I get around 8.5mpg around town empty. I have not towed with it; I'm still travel trailer shopping. Thanks for the update.
It's, according to the GM engineer for my truck, the security system for the trailer. When the truck is locked, the trailer unplugged, the alarm will go off to alert the owner. Also B&w have a hitch designed for the GM tailgates. Well worth it to be able to use the full tailgate function.
Really appreciate your straight shooting reviews and info from personal experiences Truck King! As such, I just purchased a 24 High Country 2500. Got a good price a couple weeks ago. The truck is very good for all the reasons you talk about, but I have one major problem. The seats are completely terrible! Overly firm like a bench at a ball game. A 15-20 minute test ride, twice, didn’t reveal this discomfort. But a few hours driving after the purchase did. I would expect a lot more from a rig at this price. Have you, or anyone here, experienced this? If so what did you do? I’m about ready to ghost ride it into the ocean, but it seems like a waste of an otherwise good truck. Dealer of course won’t do anything. Any insight is welcome. Thanks
I have the exact same issue with my trailer lights flashing when the trucks off and parked. I have a 2024 High Country Dually. I’ve got four different trailers I use regularly and the issue is present with all my trailers. I’m excited to see what the resolution is for this issue.
They used to be all family owned… and now the past 15 years… most changed to over to corporate owned and they have incentivized and operationalized around just that… extracting your wallet at maximum for every interaction.
I'm dealing with one now on a ranger raptor. No dealer markup thank God, but they're being queer on the financing, started out at like 20% interest despite a good credit score
@@wolfgang_h3t ! Yah… No! If locked on price then you go direct to a credit union or bank your choosing (but I find best rates at credit unions) and get their rate. Take that rate and offer dealer to originate the loan at that rate with that credit union or one of their banks. Thats fair - dealer still gets their origination kick back from the bank and you get your rate. Else tell em to write it up for your new bank loan at your bank. Also if really tough as nails… I tell em to stuff their paperwork fee when they protest 😅 as I cross it off like it was a mistake on their part.
@@wolfgang_h3t Step away. There is no way 20% is acceptable. Even in today’s business environment. Like another post said, if your credit is good, go to a bank or credit union. Not sure where you are but Lake Michigan Credit Union is Great. They have a pretty large foot print. We even have them down here in Florida.
Great video. Thank you so much for the great information. Looking forward to the follow up video. Will they go on camera during and/or after their investigation analysis? At your next oil change please test a sample of oil before taking it to the engineers.
It's really no secret now and common knowledge to not leave a hitch in receiver when wanting to use the step down feature in multi pro tailgate. I have that same colour truck with a standard tailgate I would gladly swap if you want :)
I think someone already mentioned the issue with the taillights on trailer flickering, but yeah that should be the security on the truck. My Denali did that as well. I had to do some research to figure out why my boat trailer lights were flickering when hooked to the truck.
My 24 does the same flash thing with the trailer lights when parked. My 20 did too….in fact think my 17 as well. If I’m gonna be parked with a trailer hooked up for a few days - I unplug the 7 pin. Never thought about it being a security feature…
Looking forward to your next update and what happened at your service appointment. - One question, do you find your knee hitting the Lights and Performance mode switches when you get in and out of the truck? That is one on my frustrations with the Silverado. Love the truck, but those darn switches are in a bad spot. Plus they are hard to see. It's the little things. LOL
The fact that you didn’t drain the fuel filter yet is really a concern for me as a truck guy. There is water sitting on the bottom of the filter I’m sure. Also - the B&W hitch makes the perfect solution for your hitch that allows you to drop both gates without issue.
Hold the top tailgate button for 5 seconds until the brake lights start blinking, it will lock out the small part of your tailgate, reverse the process to unlock.
Ya my truck has a key and dealership said it won't lock the gate without the key or sensing fob I was like look at this sticker say it locks 3 or 5 seconds and 15 mins later they said this one doesn't do that no reason why sorry cya. I still can't lock the top but whatever I guess just bugs me
I took delivery on my chevy 3500 srw a week after you did. Been watching your show now fow a couple of years. We have 3 recalls on these trucks. 2 emission downloads will cure this. Also the other recall is on the trailer brake controller. The module will cause you the lose connection on trailer brakes and low voltage to trailer. All of mine have been repaired and no complaints now. FYI.
x2 on checking the fuel filter (or just change it out) - super easy job. Far easier than even an oil change. I do mine myself biannually on my 2019 Duramax, and even on my old 2022 LM2.
I leave my hitch in. Got rear ended a few years ago. The guy hit his brakes, nose dived and his front bumper hit my hitch directly. His bumper and nose was destroyed and my damage was almost nothing. Hitch and frame took the energy, both were ok. The dealer is lying to you with the def fluid in gas tank. Go somewhere else but not before reporting his name on social media. Good video.
@@theglowcloud2215 Dying on a medical wait list? Too bad. Your gov pressures you to choose assisted suicide. You can’t leave your country for surgery in the US, you will be fined by your gov. Have lotsa un up there in your socialism! 😂🤮💩🤡
For the tailgate, if you hold the button for a few seconds it locks the part that folds down so you can't open it - highly recommend doing that when you have the hitch in.
We had the same electrical problem, and we found out that the RV battery feeds back into the truck electrical system and the brake lights on the trailer they will glow very dimmed you only see them at night the GM dealer could not find why but they recommended to unplug the trailer every night when you camp. They said it's a glitch in their system.
My 2022 3500 diesel at4 was good, awesome fuel mileage, really nice ride, 4x4ing was good, front was coming loose at 35,000kms but it was doing some rough bush work, on shitty roads everyday, dealership would not warranty the front end....that sucked, switched to RAM for the first time ever, nice truck, everything is good so far, really smooth offroad. It's a gas V8 and if you want good fuel economy you have to stay around 100km/h.
I also have a 2024 Sliverado with 16k on it. No warning lights but I to get the flicker lights on my Momentuim when it's parked. I also happen with my 2020 silverado. How ever I'm having a issue with the transmission not shifting up in manual coming down a hill. Love to see if you find out what you hear about the lights. I think it's a grand design issue. This doesn't happen with other trailers that I have that have LEDs.
I have a ‘24 LTZ similar to Yours. Mine has a standard box, and Yes it might be a little better to park, but not much. I use the forward camera to see the parking stall stripes, as the height of the hood , visually makes it harder to get centered in the parking space. I have also used a fuel additive, (Hotshot’s Secret), and at times I have used more than a minimum dose, with no warning lights coming on. The 3500 is more truck than I need almost all of the time, but have had 4500 lbs in it, and quite frankly it handled it with ease. I really appreciated the 470 HP of the Duramax, when hauling that load up some pretty steep grades. I do plan on towing a pretty small camper trailer on some pretty extended trips, and I know that this truck will handle it easily. My truck does have parts ordered for a recall for some component of the trailer brake. It has not affected My driving the vehicle at all, and I have not noticed any defects to turn in under warranty. Build quality, pretty much has been excellent in My experience. Maybe not the best in-town daily driver, but really shines at long distance driving out on the Freeway. In MY case I would have loved to make a half-ton truck work, but knew I would haul heavier things once in a while that warranted a bigger truck. Just My 2 cents, for those that are interested in buying such a vehicle.
Water in fuel message is actually water in fuel filter. There is a water trap at the bottom of the filter, it has a drain. Until you drain it the message will stay on. I am guessing you haven't changed the fuel filter yet or drained the drain valve. Water is heavier than fuel so it sits at the bottom and the fuel passes thru the top.
I had to get a resistor plug that goes on the trailer plug then plugs into the truck. My 2022 chevy 2500 diesel plugged into my trailers the lights would act funny. I guess there’s not enough draw from having all led lights so the truck doesn’t always recognize the trailer lights. Seemed to work fine with the resistor cable plugged in.
It’s really cool you don’t need to highlight a dealers struggles and we can see what it’s supposed to look like when you get a vehicle looked at. I can’t stand the emotional baggage at most dealers dish up. Especially when you sure what’s wrong and are capable of repairing it.
I hate to admit it, but I put DEF in my eco diesel fuel tank. I was packing the Jeep for a family trip to Arizona for Thanksgiving and had a lot on my mind. It was a terrible feeling when I realized what I was doing.
@@mikek5298 you should not be commenting on RUclips if you can’t realize that everyone can make one mistake. Nowhere does the guy try to make excuses either. U are just a prick.
There's a current recall n the 2024 for trailer brake control model replacement and something to do with trailer battery voltage being higher than the truck causing trailer brake loss. Also had a recall 3 months ago on ecm and tcm reprogram for issues with scr system which could cause your engine light
One of my best friends had a senior moment several months ago and dumped 2.5 gallons of DEF into his fuel tank. His truck drove for less than 1/4 mile before stalling and he called me. I dropped his fuel tank and flushed his fuel lines, replaced his fuel filter and all is good for the last 8k miles. His water in fuel light has been on lately though and we are going to replace the fuel filter housing that has the sensor in it. Only 53.00 from rock auto, must be a very high quality part! I have a 2023 Duramax dually and the same trailer as you, I am only averaging 8.5 mpg! I would be happy with 10 mpg.
@@marcelo403polo2 I am chasing this issue and I have an idea that my EGR valve isn't closing all the way. I will be talking to a good service manager tomorrow about getting it replaced under warranty.
I just took my 2024 High Country in for 2 recalls. 1 - Trailer Brake Module issue. 2 - DEF issue. Both recalls may solve your issues. Just a guess. I also complained that my DEF gage never shows full. Dealership told me the DEF gage is not very accurate??? hmmm
That dealer you brought your Truck too sounds pretty sketchy! It wouldn't surprise me if the mechanic added DEF to the fuel he showed you. Just so they could charge for draining the tank. It would have been nice if you took a video or a pic of the container he showed you for the GM staff that asked you to visit them. Looking forward to the update in a few weeks.
Great video, thanks! During your truck tests were you able to tow your trailer behind the same truck (4dr) with standard bed? I have about the same trailer (Keystone Raptor 300MP) and towing behind 2009 Dodge quad cab short bed and it’s not fun when I pass trucks or get cross winds.
That code could be your fuel water separator, that needs to be drained pretty regularly. Coming from a HD mechanic don’t push that off, fuel filter changes are on of the most important thing on a diesel👍🏻I’ve also got a 24 At4 3500
Logic would say when the fuel filter is telling you there is water in your fuel filter ... drain it or in fact change the filter and examine it and the contents of the filter canister. So his response to assume it can't be water in the fuel, I find somewhat perplexing quite honestly. Having a fuel tank partly full and in a humid environment with daily temperature swings causes both gasoline and diesel to absorb water due to the breathing of a tank ( unless its 100 percent sealed ) . And who knows what state the fuel storage tank is in at the fuel station or if they are keeping up with changing the filters on their pumps.
Agreed! The fuel water separator has a limited capacity before water will pass it by and enter the engine and really bad things will happen, like a blown head gasket.
@@dougpendleton1266 Or more typically with diesel injection systems the water will damage a fuel pump, & or the injectors. Another words water going through a diesel injection system can be very wallet emptying in a hurry !.
I purchased an adapter from trailer because just plugging in the bed for my 41’ fifth wheel rear camera the factory plug didn’t allow the camera to work
The only issue I’ve had with my 2024 2500 duramax is the trailer brake controller, that’s now recalled. We bought a new travel trailer with a solar panel and the truck doesn’t like it. The controller will randomly disconnect and have zero trailer brakes.
Great video. I love my 21 RAM 3500 Longhorn ltd MegaCab but I do get nervous towing my 41’ Montana HC. Dread the day I may have to make a u-turn. Just curious how the exhaust brake works for you on the DuraMax compared to the Cummins.
I have a 2020 Silverado 5.3 LTZ and it does the same intermittent check light on for about 30 seconds and it goes off. It does that every other week now. I think it’s electrical also.
I have a ‘22 3500 dually bought with 25 miles on it and have been running hot shots secret fuel additive since day one no issues. Have 173,500 miles now and at 25,000 started running ams oil. Only thing that was not scheduled was at around 100k the idler pulley locked up and took out my belt, fan clutch and fan clutch harness. Luckily didn’t mess up the radiator. I did replace nox sensor one and two at 80k. Had a check engine for nox one and went ahead and replaced nox two. When I used it commercially I would clean the MAP sensor once a week and/or after towing up mountains. The 10 speed transmission is awesome when towing. Made towing 35k loads feel like nothing and the engine brake made it easy going down steep grades. It has three stages of engine brake that each stage is set on how long you push the brake pedal. Not pressed hard to engage the brakes but just so the taillights to come on. I rarely ever had to use the third stage. Also added airbags and made a world of difference.
I believe curt makes a direct plug and play application for that hitch receiver that when opened doesn’t allow you to open that partition on your tailgate
I had a pontoon trailer hooked up to my '23 3500 for a full week this month, and certainly would have noticed my trailer lights pulsing and they were not.
@@pryme2013 I would think it would be more "ethical" to go to the dealer as a journalist than the manufacturer directly. The ownership experience should reflect that of the common owner, not someone with connections.
I really appreciate your communication style and how you articulate the good and the bad. Your experience shows. All the best with the water/fuel and electrical draw concerns.
The trailer light pulsing you are getting is an anti theft setting. When locked, the truck puts a minimal amperage out the 7-way to see if the trailer is still there. If someone were to attempt to steal the trailer and disconnect the 7-way, the vehicle alarm would activate.
I believe there is a setting in the main screen to turn it on or off.
LED lighting doesn’t require much output so it can cause flickering. Standard halogens don’t have the same issue.
I have trailers with both so I had to do some forum digging to figure this out.
This would be a good test to demo on the next video!
@@3.0Duramax22 great insight I didn’t know it had that feature thank you for sharing

Water in fuel.... Have you tried draining or changing the fuel filter yet? That is where the sensor is.
Water in fuel is normal even my 20 year old diesel trucks do it.

My 2024 2500HD w/max tow w/12K miles now had the same early life phantom no-start w/emissions system error issue (removing the main battery’s comnections cleared it and hasnt repeated since).

I’m probably going to go with a Bluetooth one unless you end up convincing me otherwise…The camera system as it stands is incredible!
I have a 22 High Country SRW 3500 Long Bed. If you look at the hitch for Fifth Wheel/Goose neck on the long bed, it is centered over the rear axle, but on a short bed, which is only 10 inches shorter than the Long bed, the same hitch and or Puck system is about 4 inches behind the axle. There is a cross member in the way, so even an after market install would be difficult to center on the axle. My guess is they did this to prevent damage to the rear window/cab area while towing. The B & W Hitch for the Multi-Function tailgate really does the job. Although I would think GM should have come up with a solution for the issue by now, but my guess is if they did, there might be retro fixes involved that they don't want to deal with. As far as parking goes, the camera system is very helpful, I have found the easiest way to access the parking camera is to stop while entering the spot and momentarily shift to Reverse, then pull forward. Our Escalade has a touch screen button you can turn the parking camera on with.
The hitch problem is a simple fix by purchasing the right equipment. B&W makes a hitch specifically for the MultiPro application. Suprised to see that you would let that happen to your truck.
he's just an old lazy guy not suprised
I immediately bought the tow and stow hitch as to not beat the piss out of a brand new truck.
Thanks for the update. I have had a sensor issue for the emissions system - apparently a bad batch that was manufacturing GM. I look forward to your update over the camera as I am thinking of doing the same. Always appreciate the channel. I have not noticed the lights on my trailer when the truck is off.
My 2022 dually and now my 2024 3500 SRW do the LED light flicker. No issue and some have explained it already. My neighbor even commented when I had the rig parked out front over night :)
I enjoyed your comments. I had an intermittent light on my 2020 1500 AT4. Long story made short after several visits to the dealer that's 30 minutes away. They replaced the correct sensor in my transmission. It was a little disconcerting for the transmission to drop into L5 at highway speed and stay in L5 for maybe a day. No shifting in drive at all.
I wanna see more on this truck and see how it goes cant wait
I simply love your videos! Thank you !
Right On Howard...truck still looks great man
Thanks - still pretty happy with it.
Greetings from Colorado!
I have the same issue with my 2024 Silverado 3500 LWB. When the trailer is connected to the truck, the LED lights on the trailer flickers as you mentioned. I just called the dealership as soon as I saw this video. The dealership says, its normal. All its saying that the truck is connected to the trailer. The draw is so little that it will not run the battery down. As a precaution, I unhook the trailer plug when parked overnight.
Best regards,
Sikander
Waving from Cape Cod, wish I knew you were coming, I would have bought you a beer 🍺
I appreciate your channel and both of your perspectives. I have a 22 gmc 3500. I thought about adding that trailering camera. But i also tow a fifthwheel and the camera plug in is down by the license plate/bumper. Its not in the bed where i plug in my fifthwheel. And i think if i jack-knifed my trailer the wiring for the camera would rip out....
Truck still looks great Howard. Thanks for the update.
On the pulsing brake light issue, I believe the parking brake sets electronically any time a trailer is attached. That might be why the brake lights pulse as it applies just enough current to keep it set. Just a guess, but I imagine that a trailer would have to be connected for a very long time to be a an issue especially with 2 batteries.
I have the same color 3500 LB, CC, SRW but a GMC SLT gasser. I've done the aux battery and trailer brake recalls/advisories. My manual says to change oil at 500 miles if you plan to heavy tow, so I did that. All 9 grease fittings were dry, and the rear differential was a quart low. I get around 8.5mpg around town empty. I have not towed with it; I'm still travel trailer shopping. Thanks for the update.
If you only get 8.5mpg around town, something has gotta be wrong with the truck, thats terrible.
It's, according to the GM engineer for my truck, the security system for the trailer. When the truck is locked, the trailer unplugged, the alarm will go off to alert the owner. Also B&w have a hitch designed for the GM tailgates. Well worth it to be able to use the full tailgate function.
I have notice the same thing with the lights blinking on our camper. We have a 2500.
NO WAY!!! 4K FINALLY!!!
Glad you noticed. Cameraman Liam got a new camera, so it felt like the right moment to finally make the move. Enjoy =)

Very excellent episode regarding ownership experience!!! 😁
Great review thank you for posting this.
My ordered 2022 3500 duramax is doing pretty well. No weird messages yet but the transmission will lurch once in awhile, it has 13k miles.
Really appreciate your straight shooting reviews and info from personal experiences Truck King! As such, I just purchased a 24 High Country 2500. Got a good price a couple weeks ago. The truck is very good for all the reasons you talk about, but I have one major problem. The seats are completely terrible! Overly firm like a bench at a ball game. A 15-20 minute test ride, twice, didn’t reveal this discomfort. But a few hours driving after the purchase did. I would expect a lot more from a rig at this price.
Have you, or anyone here, experienced this? If so what did you do? I’m about ready to ghost ride it into the ocean, but it seems like a waste of an otherwise good truck. Dealer of course won’t do anything. Any insight is welcome. Thanks
I have the exact same issue with my trailer lights flashing when the trucks off and parked. I have a 2024 High Country Dually. I’ve got four different trailers I use regularly and the issue is present with all my trailers. I’m excited to see what the resolution is for this issue.
I despise dealerships. They are professionals at robbing you blind.
They used to be all family owned… and now the past 15 years… most changed to over to corporate owned and they have incentivized and operationalized around just that… extracting your wallet at maximum for every interaction.
@@duggydo stealerships
I'm dealing with one now on a ranger raptor. No dealer markup thank God, but they're being queer on the financing, started out at like 20% interest despite a good credit score
@@wolfgang_h3t ! Yah… No! If locked on price then you go direct to a credit union or bank your choosing (but I find best rates at credit unions) and get their rate. Take that rate and offer dealer to originate the loan at that rate with that credit union or one of their banks. Thats fair - dealer still gets their origination kick back from the bank and you get your rate. Else tell em to write it up for your new bank loan at your bank.
Also if really tough as nails… I tell em to stuff their paperwork fee when they protest 😅 as I cross it off like it was a mistake on their part.
@@wolfgang_h3t Step away. There is no way 20% is acceptable. Even in today’s business environment. Like another post said, if your credit is good, go to a bank or credit union. Not sure where you are but Lake Michigan Credit Union is Great. They have a pretty large foot print. We even have them down here in Florida.
Great video. Thank you so much for the great information. Looking forward to the follow up video. Will they go on camera during and/or after their investigation analysis?
At your next oil change please test a sample of oil before taking it to the engineers.
I have the 2022 GMC Denali 3500 short bed and have the same problem with the lights on the 5th wheel, funny it's a Grand Design as well.
It's really no secret now and common knowledge to not leave a hitch in receiver when wanting to use the step down feature in multi pro tailgate. I have that same colour truck with a standard tailgate I would gladly swap if you want :)
I think someone already mentioned the issue with the taillights on trailer flickering, but yeah that should be the security on the truck. My Denali did that as well. I had to do some research to figure out why my boat trailer lights were flickering when hooked to the truck.
My 24 does the same flash thing with the trailer lights when parked. My 20 did too….in fact think my 17 as well.
If I’m gonna be parked with a trailer hooked up for a few days - I unplug the 7 pin.
Never thought about it being a security feature…
Water in fuel problem is usually a easy fix. Just drain the fuel filter or replace it. I have had that problem on new and old diesel trucks.
Looking forward to your next update and what happened at your service appointment. - One question, do you find your knee hitting the Lights and Performance mode switches when you get in and out of the truck? That is one on my frustrations with the Silverado. Love the truck, but those darn switches are in a bad spot. Plus they are hard to see. It's the little things. LOL
The fact that you didn’t drain the fuel filter yet is really a concern for me as a truck guy. There is water sitting on the bottom of the filter I’m sure.
Also - the B&W hitch makes the perfect solution for your hitch that allows you to drop both gates without issue.
Hold the top tailgate button for 5 seconds until the brake lights start blinking, it will lock out the small part of your tailgate, reverse the process to unlock.
Also B&w have a GM specific design hitch.
@@TramaineleDay5655I have it and it’s worth the price tag, all 3 ball sizes and no fuckered tailgate!
Ya my truck has a key and dealership said it won't lock the gate without the key or sensing fob I was like look at this sticker say it locks 3 or 5 seconds and 15 mins later they said this one doesn't do that no reason why sorry cya. I still can't lock the top but whatever I guess just bugs me
Not mine I tried and dealership said my fob has to be the key less but truck came with a key so i just out i guess.
Minor problems for you truck king. I have the same rig and it's been flawless.
Great video , thank you for keeping it real and factual
Just ordered a 2025 can’t wait Be glad to get red of hammering 99 dodge 5.9
Congrats!
I took delivery on my chevy 3500 srw a week after you did. Been watching your show now fow a couple of years.
We have 3 recalls on these trucks. 2 emission downloads will cure this. Also the other recall is on the trailer brake controller. The module will cause you the lose connection on trailer brakes and low voltage to trailer. All of mine have been repaired and no complaints now. FYI.
x2 on checking the fuel filter (or just change it out) - super easy job. Far easier than even an oil change. I do mine myself biannually on my 2019 Duramax, and even on my old 2022 LM2.
I leave my hitch in. Got rear ended a few years ago. The guy hit his brakes, nose dived and his front bumper hit my hitch directly. His bumper and nose was destroyed and my damage was almost nothing. Hitch and frame took the energy, both were ok. The dealer is lying to you with the def fluid in gas tank. Go somewhere else but not before reporting his name on social media. Good video.

Engine lights in new vehicles....what a time we live in.
For the tailgate, if you hold the button for a few seconds it locks the part that folds down so you can't open it - highly recommend doing that when you have the hitch in.
We had the same electrical problem, and we found out that the RV battery feeds back into the truck electrical system and the brake lights on the trailer they will glow very dimmed you only see them at night the GM dealer could not find why but they recommended to unplug the trailer every night when you camp. They said it's a glitch in their system.
There is a recall for this. It's a problem with the integrated trailer brake controller. They replace the whole module.
Love your truck it's a really good looking truck Chevy did good on design
My 2022 3500 diesel at4 was good, awesome fuel mileage, really nice ride, 4x4ing was good, front was coming loose at 35,000kms but it was doing some rough bush work, on shitty roads everyday, dealership would not warranty the front end....that sucked, switched to RAM for the first time ever, nice truck, everything is good so far, really smooth offroad. It's a gas V8 and if you want good fuel economy you have to stay around 100km/h.
I also have a 2024 Sliverado with 16k on it. No warning lights but I to get the flicker lights on my Momentuim when it's parked. I also happen with my 2020 silverado. How ever I'm having a issue with the transmission not shifting up in manual coming down a hill. Love to see if you find out what you hear about the lights. I think it's a grand design issue. This doesn't happen with other trailers that I have that have LEDs.
I have a ‘24 LTZ similar to Yours. Mine has a standard box, and Yes it might be a little better to park, but not much. I use the forward camera to see the parking stall stripes, as the height of the hood , visually makes it harder to get centered in the parking space. I have also used a fuel additive, (Hotshot’s Secret), and at times I have used more than a minimum dose, with no warning lights coming on. The 3500 is more truck than I need almost all of the time, but have had 4500 lbs in it, and quite frankly it handled it with ease. I really appreciated the 470 HP of the Duramax, when hauling that load up some pretty steep grades. I do plan on towing a pretty small camper trailer on some pretty extended trips, and I know that this truck will handle it easily. My truck does have parts ordered for a recall for some component of the trailer brake. It has not affected My driving the vehicle at all, and I have not noticed any defects to turn in under warranty. Build quality, pretty much has been excellent in My experience. Maybe not the best in-town daily driver, but really shines at long distance driving out on the Freeway. In MY case I would have loved to make a half-ton truck work, but knew I would haul heavier things once in a while that warranted a bigger truck. Just My 2 cents, for those that are interested in buying such a vehicle.
Water in fuel message is actually water in fuel filter. There is a water trap at the bottom of the filter, it has a drain. Until you drain it the message will stay on.
I am guessing you haven't changed the fuel filter yet or drained the drain valve.
Water is heavier than fuel so it sits at the bottom and the fuel passes thru the top.
Yeah that's definitely a level sensor that is tripped, not a code.
I would drain that asap before water makes it to the fuel pump or injectors.
I had to get a resistor plug that goes on the trailer plug then plugs into the truck. My 2022 chevy 2500 diesel plugged into my trailers the lights would act funny. I guess there’s not enough draw from having all led lights so the truck doesn’t always recognize the trailer lights. Seemed to work fine with the resistor cable plugged in.
great share! i’m sure everyone has a bad dealership story sadly enough..
It’s really cool you don’t need to highlight a dealers struggles and we can see what it’s supposed to look like when you get a vehicle looked at. I can’t stand the emotional baggage at most dealers dish up. Especially when you sure what’s wrong and are capable of repairing it.
Good video and look forward to hear some explanations from GM.
Great video. I am considering buying one.
I hate to admit it, but I put DEF in my eco diesel fuel tank. I was packing the Jeep for a family trip to Arizona for Thanksgiving and had a lot on my mind. It was a terrible feeling when I realized what I was doing.
You should not be driving a diesel if you cannot tell the difference between blue and green.

@@mikek5298k Mr. Prefect.
@Truck King I have heard you can program the pro gate to not fully open.
There's a current recall n the 2024 for trailer brake control model replacement and something to do with trailer battery voltage being higher than the truck causing trailer brake loss. Also had a recall 3 months ago on ecm and tcm reprogram for issues with scr system which could cause your engine light
Another good informative video, I’m curious what diesel additive you are running?
One of my best friends had a senior moment several months ago and dumped 2.5 gallons of DEF into his fuel tank. His truck drove for less than 1/4 mile before stalling and he called me. I dropped his fuel tank and flushed his fuel lines, replaced his fuel filter and all is good for the last 8k miles. His water in fuel light has been on lately though and we are going to replace the fuel filter housing that has the sensor in it. Only 53.00 from rock auto, must be a very high quality part! I have a 2023 Duramax dually and the same trailer as you, I am only averaging 8.5 mpg! I would be happy with 10 mpg.
that's what I average driving empty around my town. 11mpg at best. regen every 200 miles
@@marcelo403polo2 I am chasing this issue and I have an idea that my EGR valve isn't closing all the way. I will be talking to a good service manager tomorrow about getting it replaced under warranty.
I had my EGR valve replaced under warranty and now I am typically over 600 miles between regens and my fuel economy has increased.
I just took my 2024 High Country in for 2 recalls. 1 - Trailer Brake Module issue. 2 - DEF issue. Both recalls may solve your issues. Just a guess. I also complained that my DEF gage never shows full. Dealership told me the DEF gage is not very accurate??? hmmm
its called new over priced cars are junk
That dealer you brought your Truck too sounds pretty sketchy! It wouldn't surprise me if the mechanic added DEF to the fuel he showed you. Just so they could charge for draining the tank.
It would have been nice if you took a video or a pic of the container he showed you for the GM staff that asked you to visit them.
Looking forward to the update in a few weeks.
My thought as well.
Great video, thanks! During your truck tests were you able to tow your trailer behind the same truck (4dr) with standard bed? I have about the same trailer (Keystone Raptor 300MP) and towing behind 2009 Dodge quad cab short bed and it’s not fun when I pass trucks or get cross winds.
That code could be your fuel water separator, that needs to be drained pretty regularly. Coming from a HD mechanic don’t push that off, fuel filter changes are on of the most important thing on a diesel👍🏻I’ve also got a 24 At4 3500
lol you can’t tell everybody that… jb reviews just did this last week
Logic would say when the fuel filter is telling you there is water in your fuel filter ... drain it or in fact change the filter and examine it and the contents of the filter canister. So his response to assume it can't be water in the fuel, I find somewhat perplexing quite honestly. Having a fuel tank partly full and in a humid environment with daily temperature swings causes both gasoline and diesel to absorb water due to the breathing of a tank ( unless its 100 percent sealed ) . And who knows what state the fuel storage tank is in at the fuel station or if they are keeping up with changing the filters on their pumps.
Yeah, I would find the water separator asap.
Agreed! The fuel water separator has a limited capacity before water will pass it by and enter the engine and really bad things will happen, like a blown head gasket.
@@dougpendleton1266 Or more typically with diesel injection systems the water will damage a fuel pump, & or the injectors. Another words water going through a diesel injection system can be very wallet emptying in a hurry !.
I purchased an adapter from trailer because just plugging in the bed for my 41’ fifth wheel rear camera the factory plug didn’t allow the camera to work
There's only one tow hitch brand that made some hitches of a certain size. Specifically for GM trucks that have the split tailgate.
The only issue I’ve had with my 2024 2500 duramax is the trailer brake controller, that’s now recalled. We bought a new travel trailer with a solar panel and the truck doesn’t like it. The controller will randomly disconnect and have zero trailer brakes.
Looking forward to the update after you meet with GM engineers.
Please keep is updated, looking forward to that dealer getting an earful from gm.
It for sure has water in the fuel, it probably should get rid of it and not need manual emptying but idk I don’t own one.
Great video. I love my 21 RAM 3500 Longhorn ltd MegaCab but I do get nervous towing my 41’ Montana HC. Dread the day I may have to make a u-turn. Just curious how the exhaust brake works for you on the DuraMax compared to the Cummins.
Cummins is stronger
I have a 2020 Silverado 5.3 LTZ and it does the same intermittent check light on for about 30 seconds and it goes off. It does that every other week now. I think it’s electrical also.
I have a ‘22 3500 dually bought with 25 miles on it and have been running hot shots secret fuel additive since day one no issues. Have 173,500 miles now and at 25,000 started running ams oil. Only thing that was not scheduled was at around 100k the idler pulley locked up and took out my belt, fan clutch and fan clutch harness. Luckily didn’t mess up the radiator. I did replace nox sensor one and two at 80k. Had a check engine for nox one and went ahead and replaced nox two. When I used it commercially I would clean the MAP sensor once a week and/or after towing up mountains.
The 10 speed transmission is awesome when towing. Made towing 35k loads feel like nothing and the engine brake made it easy going down steep grades. It has three stages of engine brake that each stage is set on how long you push the brake pedal. Not pressed hard to engage the brakes but just so the taillights to come on. I rarely ever had to use the third stage. Also added airbags and made a world of difference.
Every truck review i listen to what hot shot guys have to say. You guys are the real vehicle testers.
I believe curt makes a direct plug and play application for that hitch receiver that when opened doesn’t allow you to open that partition on your tailgate
Hey if you’d have had the same Ram 3500 long bed, you’d be just as happy with its towing capability.
Not sure if you use Irving fuel, but if you do it's mostly water. Out east if you don't change your fuel filter in November, your screwed.
B&W makes a specific hitch version for those tailgates.
B&W Tow n Stow has an updated Shank for the Newer Tailgate set up
I had a pontoon trailer hooked up to my '23 3500 for a full week this month, and certainly would have noticed my trailer lights pulsing and they were not.
The problem that I see with all the new technology going into trucks is that it is new to the technicians at dealerships as well.
Just bought a 2025 Chevy 3500HD Trail Boss SRW with the Duramax....any update on the fuel issue?
I would say the fuel and mystery fluid the dealership extracted from your truck belongs to you, not them.
The question is, is it from this trucks tank or their secret stash of "bullshit the customer fluids"
What happens to people who cannot get a direct appointment with GM engineers?
No additives in the fuel for those people lol
Exactly. Special treatment to keep the journalists from talking negatively about the vehicle.
@@pryme2013 I would think it would be more "ethical" to go to the dealer as a journalist than the manufacturer directly. The ownership experience should reflect that of the common owner, not someone with connections.
There is a recall on the trailer braking system.
