Both are common problems with JL+JT. The Body, Doors, Hood and Hinges are Aluminum and that is causing the Bubbling. The Battery can be solved several ways. The Easiest and Less Expensive, is to Place a Jumper Wire across 2 Terminals in the Fuse Box. That allows the Small Battery to be recharged without draining the Large Battery. Another method is Removing the Negative Cable from the Small Battery located on the Large Battery Negative Post Connection and remove a Fuse from the Fuse Box. or Delete the Small Battery completely. I changed out my Small Battery from the Fender Well and it wasn't hard to do at all. the Hardest part was disconnecting the Front Turn Signal connector to remove the Fender.
The rust on the hinges are due to dissimilar metals coming to contact (aluminum and steel) which causes galvanic effect and consequently corrosion. Some professionals recommend to put a thin layer of insulating material between the hinge and the hood to avoid this.
Paint blistering or bubbling caused by galvanic corrosion is generally covered under the Corrosion Warranty. The warranty is valid for 5 years after the in-service date on the vehicle. If you are the first owner, the in-service date should be the same date as the date on your purchase or lease paperwork.
I have a 2018 Jeep JL Sport. Do yourself a favor and do what I did. Locate the negative ground wire for the small battery to the main battery and disconnect it. Go to the fuse box and remove fuse # 42 ESS. You will never have that problem again. The small battery is only for the ESS Electronic Start/Stop. I actually removed that small battery in my jeep. No issues.
You can do this or use a jumper to bypass the small battery. We went the bypass route on our JLU and our Gladiator before we traded it. Regarding the paint, this is a known issue covered by a five year warranty. Contact a dealer ASAP.
I have a 2021 jeep wrangler jl with the altitude package I also live in Cincinnati have no rust I bought an auto start Eliminator kit at about 3 months and have the original batteries in it
I bought the 100$ aux battery on Amazon bring to local repair shop $35-$50 after the mechanic get under the fuse box he said there are no aux batteries. I think my dash cam drained my main battery.
Owned a 2021 Rubicon that was flawless and my 2024 Rubicon has also been 100% reliable. have numerous friends with Jeeps and nobody is having any issues.
Hey brother love the channel Question : you bought the Jeep new or used It looks like it’s a bad paint job , don’t need to paint the entire car find a good body shop if you were in LA CA I could of helped you with the paint job - but first go to the dealership and they should fix the problem for you … Good luck brother
Brother I thinks it’s a bad paint job and if they wont fix it and you have to pay for the new paint you don’t need to paint the entire car need to go to good body shop . Good luck brother have blessed day , 👍🙏
Does your main battery die while towing? That means your brake lights and blinkers if connected are draining in traffic. The main battery will get totally doomed from this over and over. You need rvi towed vehical battery tender
First, there are hundreds of videos on how to replace the small battery. It is easy. Second, your JL doors are aluminum. Not rusting. Bad paint, maybe. Also, just a thought, dis-similar metals, steel hinges with aluminum doors and hood could be causing this.
10:38 Typically, they replace the doors. As noted by others, this is galvanic corrosion caused by electrolysis between the aluminum panels and steel hinges. Should be covered by the corrosion warranty if it is within five years of the original purchase date.
Hi. I have a 2019 jeep rubicon that had the same paint issue. I took it to the dealer and that had corrected the issue for free. I’m in new York and had the work done in westchester
Good idea. Same year Jeep and same option package but I don't have any bubbling on the doors or hinges. I was horrified when someone else told me about the issue. They had theirs painted a few times until the figured out it was the type of metal in those spots...always something with these cars, lol.@@SHARINGJOURNEY
Many JL’s have hinge and door bubble corrosion due to poor paint preparations. This is a known problem by Jeep and will be fixed under the 5 year corrosion warranty. Repairs require extensive panel and hinge replacement and repaint. Just got our 2018 JL back from a dealer that repaired it. Took 4 weeks but we got a free loaner. Contact Jeep Customer service for more details on the process. .
The auxiliary battery can be replaced without taking the wheel off or “short circuiting” the electronics. I replaced mine a couple of years ago. The corrosion on the panels is infuriating. Mine has the same issue on both doors.
I have heard of Jeep having some corrosion issues. The hinge areas look to be what they are talking about, dissimilar metal corrosion caused by aluminum mating up to steel. The other corrosion looks like water being trapped in pockets on the other side of the door panels. Road salt or even salty air down where you are parked will cause some of that. I lived in Corpus Christi for awhile and the vehicles suffered rust problems.
@@SHARINGJOURNEY if you were in the Twin Cities area, the vehicles have massive corrosion issues due to the road salt. I bought a Chrysler minivan from that area some years back. After a few years one of the doors rusted entirely out. The other doors were ok, no rust. I think in some cases it could be simply poor quality metal. These days, if I want a vehicle I buy it from just a few select states due to rust issues. Makes buying a vehicle no easy task but I just can't see paying the prices that are asked and getting a pile of rust.
Had a similar problem with my Gladiator. You can remove the small/aux battery completely and wire everything into the main battery. Pretty easy to do. You don't have to go through the wheel well. It's easier to remove the fuse box and get to it that way. There are some other videos on YT that show you how to do the aux battery delete. The paint issue is a known issue with some of the early JL's. I believe there was (is?) a class action lawsuit about it.
Sorry about all the problems with the jeep! Nice jeep btw!! Hope you dont get any more problems. Yes, there is rust under the paint. We had this problem with one of our vehicles in the past. Hope you can get it taken care of!
Oh dang! So sorry to hear about those issues. There shouldn't be rust forming under the paint in some of those areas. I can *maybe* see it happening at the bottom of the doors because if the weep holes are blocked then the water can sit in the door panel.
Our 22 Tundra as the same shut-off system on it. I keep mine off to. Guess I better check to see if it has a second battery on it. Good luck with the paint.
@@SHARINGJOURNEY Sure but you need to know, it can't be flat toad. I don't know why I was told to never tow it flat. But as far as I can tell you can't beat it. For driving.
They have a plug in tazer to disable the auto start feature and they also have lots of videos on how to eliminate the aux battery and just go back to having one battery.
Just remember that ALL vehicles built after 2015 (more or less depending on the vehicle) are garbage and very costly for issues and repairs ! Buy good used and you'll come out way ahead!!
Get into a Jeep dealer and document this under the corrosion warranty asap! This is a common issue due to the aluminum body panels. Google the problem to read about it. If the vehicle is less than 5 years old you should have coverage. Unfortunately it’s not something that can be easily remedied. Jeep may grind it off and repaint but the issue will come back. So frustrating!
You should have stopped at the CJ. Maybe a YJ. Anything past the 4.0 straight 6 is trash. I got a trail hawk renegade and the warranty covered the new transmission for 11000 dollars. The radio went out and that was 3000. Then a water leak showed up and they said the roof track was broken and it would cost me 11000 for a new rack to be installed 😂. A new Jeep renegade was 27k. I had them flexseal the track and the leak stopped. That was 500 bucks. They are all junk. All of them.

No, the battery does not die while towing ... I have a trickle charger that operates while towing.
That is a common problem about the paint, research it there is a class action lawsuit about it and jeep will cover it for 5 years

Just replace the Aux. battery .
Hope your swap was less expensive than mine.

My only jeep expertise….Don’t buy one. Cheap metal these days. Pray about it and you know what will happen.. Always great to hear Cindy’s laugh
It's so sad .... no quality anywhere
My wife’s little Jeep Patriot is pushing 200k miles and the only thing I’ve ever done was change the oil and transmission fluid in it.
@JFitness88 I like hearing that
Sorry to hear about that
Thanks ... so far the Jeep dealer has not been much help.
I think that rust is actually "oxidation"..common thing. Check the hinges as well.I've heard of people repainting several times.
I am going to get Jeep to look into this today

All push start do this so rhere you go. Aluminum and plastic doesn't rust. If not treated right before paint it can happen. Salt doesn't matter.

Toad?
Toad is what you call a vehicle that is being towed behind a motorhome.
Hahaha, what part of the country says that?
@roygrisham7663 we are from the south ... but pretty common in the RV community.
I’d let the paint go. It won’t get too bad hopefully. Just watch mechanical stuff closely they can get out of hand real fast with the jl.
Thanks for the suggestion.
