2012 GMC ACADIA Electrical Problem
HTML-код
- Опубликовано: 14 окт 2024
- My 2012 GMC ACADIA has been acting up for the last 6 months. The above video shows what happens during these issues. I have fixed the problem in the past by replacing the negative battery cable. This usually lasts 6-8 weeks then starts doing this again. Then I've cleaned the throttle body and as many electrical connections as I can find. That worked for about a month. When this breaks down the gauges do this and I lose the ability to accelerate. This last breakdown I have been unable to get it to work again, before I take it in I was just looking for suggestions? I've probably spent a good 20 hours researching solutions online as this seems to be a common issue. I've read multiple people taking it in and get charged an arm and leg for a solution that hasn't been permanent. Any help would be greatly appreciated. Thanks.
Most of you electrical problems with the traction control and no crank problems can be traced back to the water in the fuse block under the dash on the passenger side, especially if you have a sub roof. But even with out it they get a lot of water intrusion under the dash pull your carpet back on the passenger side if it wet under it you can about bank on water being in that fuse block.
100% correct. I had the same issues and I had a pinhole leak that was dripping water unto the fuse block on the passenger side.
Im having the problem with no crank anti thief light is on does any one have suggestions? 2012 GMC Acadia
How do we get the water out of the fuse box?
@@sharmainmillersm i am having these issues with my 2009 gmc acadia. the best solution i can up with is using a hair drier or putting a fan on it to dry it out.
@Joe Green Today I had a customer towed in a 2007 Acadia 3.6 vvl engine with the same illumination lights on plus battery light; the new battery, customer had previously installed was also depleted, so I suspected a bad alternator. Only to discover the 2 pin connection wires to the alternator had fused together causing them to short circuit, the wires are too close to the exhaust manifold. Hope this helps !!! I will update
Did it work? And how to replace the two pin connector?
Usually shorts out due to water getting in the car. EXPECISLLY in the door wiring hsrnesses ! Remove those snd shske (water will drip out) find the lesk and replsce your ecm. Youre golden!
I buy from dealer auctions . I bought one not too long ago and soon I crank it up rpm needle starts going up and down so fast . I looked under the hood and pcv valve hose going to the air box before the mass air flow sensor was loose . I hooked it up and it solved the problem. It’s worth mentioning that knock sensor will do it as well . Number one rule check for loose connectors and hoses on the engine block then put it on OBD scanner . I believe also smoke test will come handy because vacuum leak is a big issue . GMC Acadia needs camshaft and crankshaft sensor to be replaced if the vehicle has big mileage. Fuel pressure sensor on the fuel rail is another problem for Acadia with high mileage.
Hey Joe, did you ever fix it? if so what did you do? I am having the identical problems and issues. please help.
Did you ever fixed yours ?
Any luck??
I’m m having major issues with 2013 Acadia. No start No crank. No engine power. Brought to dealer. Said I have Blind Spot Harness issue. $1000 to fix. Also have seen on you tube that water gets in fuse block below glove compartment. I work in the parts industry and every repair shop owner says to get rid of this truck. This thing also has major timing chain issues.
I have replaced front struts, wipers don’t spray, passenger seat electronics don’t work, expensive headlight burned out, radio speakers don’t work properly, also get ICE message when it’s warm outside. Too many electrical problems to deal with. Sounds like water gets into all the connectors and burns them up. Very unhappy with this expensive vehicle.
If you disconnect the 2 modules under the rear bumper that control that blind spot/rear detection it will solve the issue.
Most of you electrical problems can be traced back to the water in the fuse block under the dash on the passenger side, especially if you have a sub roof. But even with out it they get a lot of water intrusion under the dash pull your carpet back on the passenger side if it wet under it you can about bank on water being in that fuse block.
This is Dave I am using my daughters account.
Here is another place to check for water. I have had the same problem on my 2010 Acadia. Open your door on the driver and passenger side. look for the electrical plug from the door to the frame. pull it apart and look for any moisture and or water. Pull the plug from the door down and make sure there isn't any water, let drain out if there is. Inspect the conections on the plug and look for sings of corrosion. At this point I spray the conection with a dielectric spray or WD40. Eather one will work. Do this on both doors whether they look wet or not. If you have the sun roof you need to make sure you clean and vacuum out the drains on both sides of the sun roof. This has been a reoccurring problem especially during the wetand damp seasons or when we have been travling a lot in the rain or I leave the Acadia out of the garage during damp and rainy weather.

i have a 2009 gmc acadia, i just bought it! its a nightmare from hell! i pulled those door harnesses and i got about a cup of water out of each. its been raining all week here so i cant really dry them out. this car leaks like a chicken wire submarine! its a sad deal i got myself into... i have so many electrical problems that i dont know where to start. i think i am going to drive this car to Oklahoma and let it sit in the dry heat for about 2 months, let it all dry out, then start from there.
Sorry to everyone asking for an update! I ended up trading the car in because I couldn't find a permanent solution. I wish I had a better update.
I’m in process trying to resurrect my 2007 slt. All types of electrical issues. Water leaks. It’s a nightmare.
My Acadia’s new trick is to continue running with the ignition off.
Ours did this today, did you resolve the issue?
Had the same problem in my gmc and I changed the break pedal switch and it took care of the problem the part is like 20 bucks
Alternator, battery or cables to either.. or ECM going bad... did you ever get this fixed?
Any update of what was your problem?
This is Communication issue: it's likely you have one or modules down.
it could be a harness issue due to water intrusion on the PS Pillar,
An aftermarket alternator, a problem with your ECM harness under the hood, another module or even a PCM.
after doing a scan if the ECM module has no codes see if you can enter the module and access data stream.
if you can't: verifying Powers and Grounds on both the BCM and PCM
Restore communications: locate the JX205 splice pack (under LF dash) and remove the comb.
Then Rescan and see if the codes p0615, p0621/2 are in your ECM:
this will indicate a problem in your charging system. if not it's likely you either a bad harness or a bad module.
My 2013 Acadia has same whacky electrical problems. Radio has been acting up for two years. Yesterday power widows stopped working, traction message flashed, battery went dead. Jumped it. It started but would only drive 20 mph. Lost power brakes, the dash went black. When I shut off the car at the service station the key wouldn't come out of the ignition. Waiting to hear now what they find.
What did you ever find out? Mine is having a similar issue but the car won't start.
Its the bcm
I have almost the same thing. I have a gmc acadia 2008. I can't open the trunk of the car. I can't go unlock / lock I can't get water I don't spray in the wipers. He didn't even start last time. I reset the battery so now it starts but other things don't work for me as I wrote
@joe Green hey brother its happened with me and 100% try this.. there is a plug on the gear box open the car hood on your right side and look down to the gearbox and shake that plug left and right all those messages of attraction control will gone and if you wanna be sure take that plug off and return it back after cleaning the pins and the hols by blowing air .....just try it am sure 100% ...Happy to hear back from you if any of you guys try that it will work am sure..Good luck for all
It works for me in the beginning but it comes back , could u tell me did u find any permanent solution ? And what is that
No got a different car for my son to drive so it’s just been sitting. We had water damage which rusted some wires. Possibly need to check the ignition wire I soldered before. Someone suggested it’s “dieseling” which I guess leftover carbon somehow ignites in the cylinder I’m prob messing that up a little but. I wouldn’t say this engine is dirty. Not sure. But I haven’t looked at it recently.
The fuse block needs replace water leakage on passenger side windshield sill and fire wall cowel need to be re seald check under carpet on passenger side for signs of water damage where the fuse bloc is located the water drips into entire block
So all these desperate people looking for help but if any of you finally did fix yours, well none of you came back to help anybody else!!?? Where is the fix people?? I have saved this video and if I fix mine I will be back here to tell you all what it was.
I need help on mine too
I’m here taking screenshots for the mechanic 🙄 for my 2012 - I went thru 2 dealers over last 2+ years - I’ve bought batteries, sensors, BCM, and mass other parts I was told were the issue. Two weeks ago, I picked up car after dealer replaced engine. (I won’t say how much but I felt trapped with used car prices atm and they gave me a warranty so I opted for repairs). The car is STILL having same issues!! I bet whatever they tell me next isn’t going to be covered by that warranty!
Good luck! I’d say if you have the means to get something else…do it!
Welp, we’re waiting…
Mine was doing exactly the same thing and that fix for this problem was the high pressure fuel pump. Located under the air intake.
You have to take it to the dealership for an ECM flash. About $200. New cars are junk now.
Hello, I have a gmc acadia 2010 , the fuel gauge is not working. I tried to replace the sensor in the fuel tank but it didn’t work even I changed all the panel or the table I don’t know what’s it’s name but it didn’t work can you help me please
I’m having same problem can you tell me if you fix it how and what you did please
After my GMC Acadia and the electrical problem it thought me a lesson don’t ever buy a GMC anymore .
I just had mine in the shop for doing almost the same thing and they replaced the timing chain and the water pump along with an oil relay switch plus a gasket and a pile of seals. To the tune of nearly $2500 and it’s still doing this occasionally. But within seconds it stops and when I take it to check the codes to fix it...none come up. Help plz!!!
Stupid question. Where should the battery gauge be when running? What’s the normal spot? My Acadias battery gauge runs in the middle area but sometimes I start it and it is almost running at the top or 3/4 the way up. I’ve also noticed when I reverse and my passenger side mirror tilts down and I put it back in drive the mirror comes back up and stops half way and I have to manually move it with my controls. Please help? Thank you
Hey
Did u manage to fix the issue as am facing the same issue
That's not an issue. It's a setting in your controls on dash. As for the battery gauge middle to 3/4 is normal. 13.6-14.2 Volts
It’s transmission or low oi pressure my gmc is same version only thing with my truck is abs light on traction control light on and brake light on still drives perfectly
Had the same issues. Bought a new throttle body from Rockauto (buy Bosch $130) haven't had an issue for over a year now.
We're your issues exactly the same with all gauges losing power except for the voltmeter?
@@Anth1485 for my gauge issues, I sent my instrument cluster to a company on eBay. I had to do the same thing for my Audi TT.
@@Anth1485 look up ezelectronics201 on eBay. I sent mine in February 2020 with no issues thus far. They were quick and the cluster was easy to remove. Good luck
@@devictorp did the car also stalled and lost power
@@davidcobarruvias4185 yes. the engine sputtered and the traction light came on. It was in Limp Mode.
My 2012 Acadia is currently doing the exact same thing. Would appreciate some help diagnosing this.
Try to look for the mass airflow sensor if its properly installed back on... try pulling it and put it back..
Sir did you ever get the issue fix
Bcm module is bad i have 2008 slt everything else is brand new and was replaced. Dont let them charge you for something else. But only the dealer can do it as they have to program it to your specific car. Be careful as well as having this issue can cause it to ruin your battery so unplug it when you can. Just because you turn the car off doesn't mean it all goes off. So weve had to disconnect the battery to get it all to shut off.
How much does it cost when you go to a specific electric car
I have a 2008 GMC Acadia LTE.
First time I got the warning after a big rain storm going up a hill the next day I got the warning. And then the truck wouldn’t go no faster then like 20 mph. Took it too GMC. It was the drive shaft. Costed about $4000. 2 years later got warning again. My wheel barring was bad. Got the part off eBay 150.00 to get it fixed haven’t seen it. Since. Fingers crossed
Did you try replacing your computer? That's prob the issue try it
Hey, Joe, I have a 2012 GMC ACADIA same issue I would like to know if you got it fix?
I appreciate your help
My temporary way to fix its I got an OBD reader I connected and clean the codes and start working again
Same thing I did!
Hey Joe, did you ever fix it? if so what did you do? I
My car is having this same problem how did u fix it
Have you fixed yours ?
I have the same problem did you get it fixed
Hi, I have an issue with Acadia 2014 when I'm driving engine light will come on and the traction light will come on then the car will shut down, and won't start until I keep it off for a day or 2, or try my luck with moving the cables under the fuse box
anyone can help?
Any update here? I'm having the exact same problem on on my 2012 Acadia. It usually happens after I turn the car off and then turn it back in on a short period of time...like it hasn't had a chance to cool down or something.
Replace the ECM (Engine Control Module). RockAuto has the part. The dealership will have to program it. Part is about $140, programming costs around $40
Greg Wilkins when the ecm is bad does it also shift into park when you put it in drive? I’m asking because my 2011 Acadia is doing the same thing as on the video, but also if I shift into drive it shift back to park then back to drive.
Fixed it then I traded it in while it still ran
@@gregwilkins13Where is this unit sold, and what is the part number
شكرآ على المعلومه الجيده
When I turn on my heater on my 2011 the car shuts off. When I drive w/out the heater the rpm goes up and down. Does anyone have any suggestions
That also happen when you put a different tire on the car
Try the wheel bearings on the front right or left I had the same issue with mine it sounds stupid but there's a magnet on the back that falls apart and makes the car do a bunch of stupid things
I bought mine in April this year been in the shop ever since mechanic can’t figure it out
Replace ECM... Promise itll work.. Its the computer for the car. Rock Auto has one pretty cheap. Dealership charged about $40 to program it.
What is ECM
@@alialhammadi8263 Yes. What is ecm?
What is ecm please?
Engine control module
Same issues as described and I tryed changing the ECM and it didn't work. All that did was make my timing chain tensioners lose prime.
Hi, i am facing same issue. i have changed fuel pump, fuel rail back and front but still same issue ( traction control off, service stabilitrack, engine power reduced) same issue shiwyagain and again please kindly suggest solution if anyone fixed- thankyou
Clean out your drains and your top window and that will stop the water from draining down into the car and put a heater on the floorboard and dry that corner out on the passenger side of the car that will fix your problem. drains get plugged up in the sunroof there's one on each side in the corners. the water leaks down and gets into the fuse box and that's what shorts it all out, car won't start or nothing. the GMC Acadia are bad about that.
I have same problem i went to 7 different mickaneks shop no body know and every body tell me different thing. I got tired then i came with crazy idea when i go home i remove the positive cable from the battery. It been working last 6 months because chaning battery or alternater Will not work. . U will pay more money for nothing will be little work But it's worth it
Did you replace new positive cable? Mine doing the same thing. I was thinking about replacing new positive cable.
@nizar sarhan
Beat on the dash till it stops shorting out
Try to replace or fix the Electrical Gear Plug.
Is the abs module
It a sealing problem, 2007-16 are notorious for this, just happened to me 2hrs ago
Sealing what ?
If it fixed the problem when you teplaced the cable that means you have a bad ground and a connection is bad you need to get a ground schematic and check the grounds that are going to the problem
I'm having some problem with my 08 Acadia I plug my scanner up and give me a code pcm I put new one in it same thing you go to start it and it loses power if you get it started it run for a few sec and quit
Look into the gas peddal and sensors it will come as a whole replacement. I would scan to get codes first tho
Bingo
ecm needs to be replaced.. common issue with these
It could be one of you coils on your spark plugs
Did you knew what causes this problem
Alternator issues
Alternator
Electrical problems,transmission problems. Engine/timing chains ⛓ problems. Gmshit
Bad ground under the hood
Fuse box
We had to replace old Alternator
Last time it happened it was the spark plug
Mine turned of in traffic
My too i had my 3 kids with me
Altinater for sure
@@owllord5792 truck be acting up I still have it lol
I know because my focus stopped while driving and it was altinater
Now iam having trouble with my gmc arcadia , that's why I am here , come to find out it's the ecm control module which I can't get from auto zone so gonna look online , dealerships will rip you off"
Clean the throttle body! If that doesn't work, replace the Throttle position sensor. There are two. One under the hood, one behind the accelerator .
The engine doesn't know where the throttle is so it's in limp mode.
You must replace them both together.
I know exactly what's going on when that truck I have that problem before and I fix it
What was it?
Sound like u need a new Vapor Canister Purge Valve Solenoid
Ecm
We have a 2013, just bought it, 2 weeks later, the same exact issue, brought it back to the dealer, he laughed said, “ You bought it as is” shit bag!
Mine started today when it was raining. I’ll check for water getting in the fuse block.
Jason Allen ruclips.net/video/d_iZbTJG1BQ/видео.html here’s the fix lol. Dealers suck
Ever figure it out? Same story here only mine isn’t doing the rpm bouncing. It was raining the other day and those messages came up then it jerked when we accelerated really bad.
Alternator
