Rear window leak

n8huntsman · December 1, 2020

Out of curiosity I charted the number of pages of posts by month to see if a trend is forming. My leaks were all after washing, not rain because I'm in California. But still not exactly scientific because obviously leaks are gonna be noticed more in the wet months so impossible to say it's temperature related... Still interesting. We'll see if there is another massive spike in Jan/Feb.

Doesn't the lemon law only go for the 1st year of ownership?

My second window failed after exactly one year, to the day. I noticed after washing it both times. This time was shortly after our first frost. Thermal cycling maybe? Took about 9 days to replace with another new window. I took it to a different dealer this time. They did a much better job but unfortunately the damage had already been done by the first dealer. However, as soon as I opened the door I immediately heard the sound of the pressure equalization flapper valve between the cap and bed. Took a peak in there and guess what! It was dislodged again lying between the bed and cab just like last time. Took them over a month to get the part last time and a week to install it. This time they ordered the part in about a week and we'll see how long the install takes. They have to remove the bed to get to it apparently. I've got a case open with GM waiting to see if theyll do a buy back. I had the caulk job done, and now two windows so that should count as 3 repairs for the same issue. If they don't do something to satisfy me I'll investigate the lemon law route because I have zero faith that this new window wont be leaking come next November.

Can someone from GM just please read this, this is too common with this attempted repair, and why people are frustrated!

Depends on the state. Some allow for duration of warranty.

I have a simple fix for the bulk of GM's problems. They need to stop telling suppliers to "sharpen your pencils". I knew a guy who was a GM supplier. He gave them the best price for the best parts that he could provide. He got fed up with GM coming back to him every time he submitted a competitive bid, being told "sharpen your pencil". Last I heard he became a beta tester with HPTuners, started doing work for other companies, and started working with some NASCAR teams for electronic tuning when the cars jumped over to EFI. To him, "sharpen your pencils" was another way of saying, "use inferior products". Look at what it has done to GM over the decades. GM isn't alone with this problem. "Saticficing" seems to be a business term GM hasn't figured out yet.

Well I picked up my truck from a detailer and he told me my rear window leaked a little. Scheduled for the dealership to see it Friday. After reading this thread I’m not super excited about all this. It’s a 2020 1500 RST crew cab that I got in January. Really enjoy the truck but not thrilled about a possible repeating issue like this happening. Wish me luck.

Best of luck!

2019 Silverado 1500 LTZ (Black Ops edition by Tuscany).

Not sure how to check when it was built but according to my VIN it was in Mexico. I cant seem to find the date on the door.

I joined the leaky rear window club yesterday morning. Well probably before then since I had weird moisture building up on the interior of the cab and for some reason my windows just kept getting fogged up so easily. Driver side is leaking pretty good, passenger side is a couple drips.

I called the dealership and I'm scheduled for Dec 18th and they wont let me have a loaner. They want to charge me $35 a day to get a rental car through them. I opened a case with GM already.

After reading about 120 of the 173 pages here, I'm tempted to do the silicone fix since I'm pretty good with shipboard electronics and use the marine stuff already. I'm just not too familiar with cars/truck maintenance repairs if its not an oil change or tire change. I'd also have to rent a dry space/garage since my truck doesn't fit in mine.

I'm really concerned with water getting in and since its freezing at night here in Washington it will just cause further damage. Which I suspect is what triggered the water to be large enough for me to see it now. I've got a waterproof truck cover on its way but its going to be a huge hassle taking that off and on if I want to drive the truck and now on rainy days I need to leave it covered at home. I feel extremely robbed of the new car/truck experience from GM. I really wish there was a recall and permanent fix from GM already. I love the truck even though this will be the second time in the shop(a front left shaft broke already, J, F, or S, I don't remember but I still have the paperwork). I've owned the truck for 4 months and its spent 1/5th of its time at the dealership and with this it will only extend the time spent away from me.

Edit 1, Dec 3rd: Changed dealerships to fix my truck. Going 30mins further to the next chevy dealership since the tech I talked with knew exactly what my problem was and said he just fixed one two weeks ago and I'm having the exact symptoms. Still they don't have a loaner vehicle either... its a Chevy Equinox for $35 a day.....

I'd go to a different dealership. I did not buy my truck from the dealership that I have handle my warranty issues and they have no problem giving me a loaner (car) for as long as I need.

This would be great news if indeed there is a new design for that back window that has a more robust frame. I think that just might help mitigate some of these leakers.

I might be able to tell you soon. Mine is going in for new window tomorrow. I’ll see if I can get the part number off it or any other info from them. Hoping they don’t mess up my truck putting it in...

Well, update on mine. Went in on Monday for new exhaust, there was a rattle at cold start and they found something broke off inside... and the new window that came in. They fixed the exhaust Monday but didn’t get to the window... then on Tuesday their “window” guy had an emergency and couldn’t get to my truck. Then today I get a call that he removed my old window but when they went to get the new one they saw a hole in the box and then they found a “blemish” on the window frame on the outside portion. They texted me and sent me the pic I’ve attached and said that they don’t think I want that window and I said NO! So now I’m waiting until next Monday for the newest window to arrive! Ugh.... and so it continues.... I just texted my service guy and asked him to look at my old window tomorrow and see if there are any cracks and to send me pics as I’m keeping track of everything for when this new window fails and I have bullets for GMC....

Just looked over my paperwork from the window installed last week. It is the new part number 84944319. The frame might be a bit thicker but without measuring the old one with a caliper I can't be sure. If anyone measures theirs I can measure mine too

Can you post a picture of your new glass like this ?
