Rear window leak

JohnCasey · February 27, 2020

Jamie that is not right at all and from the wording you typed you know that as well. Go to another dealership and show them as well. I'm on my first replacement window and am getting no where with GM as far as any compensation for the 79 days out of service on my truck. I was in a loaner Malibu so they are saying there is nothing owed to me at all. They have so far offered four things I already have like onstar and extended warranty and a $100 GM service voucher. Good luck with a lemon law case.

For sure it's not right, I don't care if it's coming inside of every vehicle built. Water should not be coming inside the cab. When my carpet get wet again, I'll just take it back. And same here with GMC, I currently on my 3rd advisor and have no help out of any of them except maybe the first. I'm currently waiting of my 2 day call back, which was supposed to be yesterday. Crazy situation!

you need to hire a lemon law attorney. 75 days out of service qualifies for lemon law and them to replace or get you out of that truck. The only way to proceed is legal action. Good luck.

100% Agreed. I got all my money back and my down after 30 days and 4 times of the same issue being fixed on my 2014 Sierra . ( steering wheel binding)

Go to the BBB and start there and if not there are tons of lawyers who make a living of this stuff . sorry to hear the trouble

Make you some big cardboard signs describing your problem and the lack of resolution, post them on the sides of your truck, and park it just across the street from the dealership.

If they don't call within a few minutes, call the local news station out there to speed things up.

Mine is still dry as a bone and I don't feel like reading through 118 pages. Excuse me if posted before, but the TSB seems to address a the proper procedures and materials used to stop the rear window leakage.

I almost bought a new 2019 Sierra AT4 today, it had 11 miles on it. I had read this forum as part of researching. I noticed that there looked to be water spots on the inside of the rear window. I had the salesman take it through the car wash. There was a stream of water down the back window. They said that they had never heard of this before, but were going to apply caulk and for me to come back tomorrow.

The price sounds like a good deal, but I don't know if I want to mess with the potential problems that ya'll are having. My current truck is a 2014 Sierra with 234,000 miles, I'm debating about seeing how long it will go before it breaks down.

Thanks for all the great info guys.

Run away as fast as you can.
the only way I’d consider it is if they replaced the window and then sold it.

otherwise go look for another AT4 elsewhere

The thing is, they all do or will leak. If you want a 19 or 20, they will all eventually leak. The question then becomes, is the GM fix and dealer implementation of that fix sufficient? BTW, if your dealer service dept said they'd never heard of the leaky rear windows, they're lying out of their arse.

There is no proof that they will all eventually leak, just like the fact that everyone will not catch the flu. In fact the majority of those polled on a post on this forum, which unfortunately fails to capture the specific production facility, indicates just the opposite. Only "proof" is the hope, bad luck and tears of those who got stuck with one that leaks wishing that others will be just as unfortunate to justify their unfounded speculation that somehow everyone will eventually equally suffer.

Ft. Wayne USA production, dry as a bone and been through many high speed runs in mountain thunderstorms. Don't high pressure car wash, don't leak, don't have any 8 speed transmission problems, don't have any other complaints.......only vrrrooooom, vrrrooooom.

If you are stuck with one and want yours fixed correctly find a responsible dealer even if you have to waste a tank of gas to find one and give him a copy of the TSB on the leak issue which he should already have and be aware. Can't just let some jerk blindly loose with a caulking gun and hope for the best. Note that the window alone may not be the problem and the holes anchoring the spoiler should also be examined or they may fix one leak and fail to correct another.

Hey Thomcat, you know you just jinxed yourself. My truck is great as well. All my recalls done, my 8 speed transmission is smooth as silk. Only issue is a leaking rear window that they cannot seem to fix. The TSB has been proven not to work on a lot of trucks, and like you said, if your dealer is not good, doing the TSB can lead to other issues. A leaking window is not something to worry about until it is happening to you. I just read a couple of days ago that a truck owner with 42,000 miles on his truck has started leaking. Hopefully your will stay dry, I would not wish this issue on anyone, it's a real pain in the butt. Fort Wayne, USA production, wet as a sponge.

I had the TSB done in early December. Many heavy rains and car washes since and no leaks. The dealer appears to have done a good job. No caulk visible, no stains, no scratches. I can't even tell they did anything at all. I could smell the curing sealer for a few weeks. I look back there every car wash or rain event. I took it to Goldstein GMC in Albany, NY. I probably just jinxed myself too.

Thomcat, I appreciate and respect your feedback, positive outlook and faith in GM engineering and I hope you as well as most others never get this leak. GM engineering does get most things right (6.2 rocks, 10 speed tranny is absolutely perfect for my tastes, etc.). However, after owning a 2016 Yukon Denali that was stellar in every way except low speed booming and random high speed vibrations, I have a bit more skepticism. I was close to buying a K2 but feared the dreaded Chevy shake not because of the shake in and of itself, but how it was unfixable and how GM treated those that had it. "Denied, within spec". I see the same thing going on here. Issue identified,->GM proposes band aid fix to both keep warranty costs down and run out the clock on the warranty-->customers dissatisfied-->online ranting--> sales steady so who cares, etc. Typical GM new product launch: inadequate body integrity and NVH engineering, inadequate testing, customer failures mounting and band aid fix.

Personally I am glad I had the leak and had it fixed but I am not entirely pleased it was fixed with caulk. I sleep easier at night knowing my truck does not leak. It took my truck over a year to leak. Fort Wayne, Oct/Nov 2018 build.

Thomcat · February 28, 2020

Like I said What me worry? Haven't had a ride with more than 25K on the clock in almost 20 years. Had an Avalanche with lkess than 8K that leaked like a sieve. Same solution if it leaks, it gets traded, thousands of more new ones always on the lot.

No jinx, simply increasing my chances to get a new ride........kids don't need my money and I can't take it with me......and damn environmental regs prohibit burying in- a new 'vette instead of a coffin.
