Rear window leak

J_Cool87 · February 6, 2020

Have any of yall recieved any type of compensation from GM or the dealers that you purchased your trucks from with these issues? If so what did you receive and did you ask for compensation or was it just given to you?

I’ve got the use of a POS silver Chevy Malibu. That’s the only thing I’ve gotten from my dealership. I haven’t asked for anything. It’s GMs issue. Not theirs.

GM keeps telling me that they want to give me compensation but they can’t tell me what. They only say I have to wait until my truck is repaired and then and only them can they talk about compensation. Kinda like a health care law. Got to pass it to see what we just voted for

Seems like some silicone around the window seal would fix the problem, but you shouldn't have to do that on a new vehicle.

Sitting here thinking after reading about a lot of the issues you guys are having with quality of work done and the condition you receive your vehicle back in. In any other instance, this would be considered vandalism, it just so happens the dealer can fix it so it’s not.

The lack of respect some techs have for other people’s property is inconceivable.

As I mentioned previously I had my truck in for trans problems, and had them balance the wheels and tires. 3 out of 4 wheels came back damaged. Driving along tonight the (cover on the bolt hole) passenger A pillar handle fell off. Looks like the tech broke the clips on that.

I’m taking mine in later this week for the leaking window and am going to beg and plead with them to return my truck in the same condition I left it in. Unbelievable we even have to bring something like that up.

I have heard the same stories but pinned them down on a number in writing with email / text. Haven’t received any of it yet since I haven’t actually gotten my truck back yet. We will see

So after all the advice I've given him based on what I've read on here, my brother bought a 2019 SLT with a sliding rear window. I guess all I can do now is hope and pray it doesn't start leaking on him too soon.

Yeah, the automatic car wash theory is a red herring.

It's not the "automatic car wash theory", it is the "only cause ain't necessarily the window frame or window frame sealant theory" and sealing the frame alone may or may not solve the problem.

Even assuming the frame is not cracked and/or sealed 100% it addresses only part of the potential leakage problem. There is a thin, very thin, pressure fit gasket without sealant sandwiched between the metal body and the polymer spoiler. Spoiler is attached with screws and clip retainers that fit into holes in the metal roof that extend into the interior directly above the headliner. Leakage at any one of these holes drips onto the headliner which loosely rests upon the inside of the window frame causing the water to drip along the inside of the window onto the seats and floor. And, this will occur even if the rear window frame is cracked or not or even 100% sealed to the body.

So the best guess is this....and take it for what it is worth.....if the leak is due to a cracked or poorly sealed window frame then replacement of the frame will work, but if the leak is caused by leakage past the pressure fit gasket , that will not help and water entry will be through either a screw or clip hole in the metal roof. Been there, done that with the trunk leakage on my Camaro, dealer was constantly playing around with the lip seal while I found that leakage was past the gasket and through one of the screw holes through the trunk lid.....another time through a screw hole past a roof rack seal. Exhaust gases or coolant can find its way through a defective head gasket....the spoiler and roof are milled nowhere near the tolerances of a block or head, so likely water under pressure , or could just through a poorly fit gasket, can find its way through a hole in the roof into the interior.

Hand washing may not help if the gasket is defective, but certainly reduces the risk of entry under the spoiler seal. Photos show the fine fit and finish of the body against the ultra thin gasket and at least a portion of mine will permit a piece of paper to get partially past the gasket seal......nopt forcing it becuase I don't wnat to create a leak........think a blast of 300 mph air could force water past that gasket?

For my .02 if it was me doing the repair each clip retainer or screw hole though the metal roof securing the spoiler would get a big glop of silicone rubber before replacing and anchoring to the body. This way if water gets past the spoiler gasket, it will not drip onto the headliner and compromise the interior.....and if necessary the spoiler could still be removed with a little bity of effort if necessary in the future.

This is their classic delay tactic. You will get something when done - accessory vouchers or maybe a months car payment. If you want real money for them "breaching warranty" you have to get a lawyer (who will of course take some of the money.) You're screwed coming and going.

Well I dropped my truck off this morning so lets see how well they can “fix” my truck.

Has anyone had any success after a repair? Just out if curiosity

disneybaker · February 6, 2020

Then in theory, no sliders could leak as well?

Yeah that's what I figured. In fact I've already told them not to insult me with a cheap GM accessory (that I don't want to begin with or I would have bought the darn thing) offer. So far I'm out Deer season with my son, approximately 175-200lbs of venison, the entire fall and early winter of astronomy(got to go out to the farm its too light polluted in town here), fall speckled trout fishing(cant pull the boat with a Malibu), cooking at church and other random events I use my pig cooker for, Work(I can drive around but I can't haul pipe or water heaters or anything other than small parts), have to use my wifes car to take dogs to the vet, my wifes transmission(that one cost me $2,710.38) that went out after our trip to WV that I would have taken the truck, $500 tow bill to get my wifes car towed back from Ski trip, and no telling what I can't think of. I'm sure GM is under the assumption that because I have a loaner and its being repaired under warranty that this isn't costing me anything. Heck if I have to replace that deer meat lost with beef at 5.99/lb I'm out $1,048-1,200.00.
