Well...gave up and traded mine away. 7 months after my last repair, the dealer says "labor warranty is only 90 days. Part failure warranty is 1 year. You'll have to come in and let us see which one it is. You're out of warranty at 38000, so you'll have to pay for the leak check and the repair if it isn't a part failure." After my $11000 check from GM and the trade allowance, I essentially paid $2000 to drive it for 2.5 years. Can't say I was sorry to see it go. Too many first year issues. Hope you guys get your leaks resolved. Stay on top of them and if you have more than 4 repair attempts, I recommend hiring a lemon lawyer and sending a demand letter to GM. I used a reputable firm out of Mobile, AL. Not hard to find one on Google. Took about 5 months, but I did get paid eventually.

The way I understand it, the entire back glass is encased in a plastic ring. This plastic is easily cracked while installing. My theory is any, and I do mean any, body flex will crack this plastic ring too. It's been April since my last update. Quick summary Purchased in March 2019 First leak 1 week after purchase. Dealer reset spoiler Second leak in Aug 2020. Dealer remove and reseal existing glass Third leak in Jan 2021. Dealer remove and reset the spoiler Fourth leak in Feb 2021. Dealer found over-torqued spoiler bolts and damage to spoiler mounts. Replaced all mounts Filed complaint through lawyer to GM. Fifth leak in Apr 2021. Dealer ordered new back glass. Siliconed the entire top glass. Leak tested for 24 hours in spray booth. No leaks but they forgot to reattach the 3rd brake light so had to disassemble and reassemble everything GM said 'Sorry' with a fat check in Aug. I wish they had just given me a refund. Nov 2021: leaking again from a new spot. And of course the entire service dept has changed over in the last 7 months and they're wanting to start over from step 1 with a 3rd party leak detection company. I'm so done with this truck. Anyone want it? I'll make you a good deal.

So after 3 days of regular mixed driving about town...some interstate, some downtown, lots of 55-65 mph stop and go highways...I've averaged 15 mpg. The Toyos are heavier than the little Wranglers I took off, so I guess it should be expected. I won't know long trip mpg until next month when I have to drive to Orlando.

So far avg says about 1 mpg less. Given the speedo is off about 1 mph, that could be the reason. Honestly, I haven't driven but about 50 miles since I put them on. Chillin and grillin all weekend. Back to the grind tomorrow so I'll get a good sense on in town mpg this week.

Pic from 2019 before the Rhino-lined lower and steps. Towed this 21 ft Tahoe from DC to Huntsville. Didn't even know it was back there.

Not too loud. Definitely not as loud as a pure mud tire, but just slightly louder than BFG KO2s. They may quiet down after a few miles to break them in. I will say they have a stiff sidewall. Much harder feel going over speed bumps at 33 psi. Could be that my Wranglers were wore out too.

The Yokos are 1” taller than the 265 Wranglers, at least to the calculator below. Speed difference varies as speed increases.

GPS shows 51 mph at 50 mph speedometer indicated. I can live with that.

Side by side comparison of the factory vs the Yokohamas

Finally pulled the trigger on new tires today. Went from the factory 265/65/18s to 285/65/18 Yokohama Geolandar X-AT. My son got them at his shop at a great price. Great fit on the stock 18s with a Rough Country level.

Somebody needs to be let go for that shite. I would have lost it.

So my saga may have finally ended... After the 5th repair attempt, it is NOT leaking. They replaced the entire back glass and remounted the spoiler again. After major rain here all day, it bone dry in the cab. I did check the glass install and it's level and square. The only different thing that I can see is a bead of clear sealant was run between the top of the glass and the cab frame. You wouldn't notice it if you didn't know it was there. So maybe...just maybe...my 2 year issue is over. We'll see how long it holds up. As for GM, they have until the 26th to respond to our demand letter. I will have to decide to move forward with a suit or drop the case if I don't hear from them after Monday. It's been in repair for 41 days total, which triggers the law in Alabama.

Mine went in for the 5th repair attempt yesterday. This time they're replacing the rear window with a new one and they said they're gong to redo the spoiler for a 4th time. I'm going to ask them for a water hose before I ever leave the lot. Thanks to @Jeepincbum55 I'll make sure I check the level on the rear window replacement when I pick it up.

They’ve been steam cleaning it each time. This week I’m going to push for a new headliner

4 repair attempts. New window is here and will go in this week. We'll see if it finally fixes the issue or if the tech screwed up my truck when he over torqued the spoiler bolts during repair #3.

I'm with you. My 1993 1500 stepside 4.3l was a rock. 243,000 miles and never had a problem. Towed everything with that truck. Crossed the US twice towing a car. My 2019 is currently in litigation for buy back due to the rear window/spoiler leak that has been repaired 4 times and is worse than ever. First leak was 2 weeks after I bought it in March 2019. Other issues that have been reported or 'we don't have a fix for that now': Radio presets stay on the first 5 presets. This is a weird one where you change preset channels and the screen jumps back to the first 5 presets - no fix Climate control on screen shows climate off when it's actually on - no fix USB chargers on dash are crap. Sometimes they work, sometimes not. Both B and C points on both Android and Iphones only work sometimes. - replaced, still does it Tailgate won't open 50% of the time. No tonneau cover either. One day i pressed the tailgate button at least 50 times and it finally opened. Dealer said "could not replicate" Transmission is all over the place. Shakes like crazy when I tow my 4000lb boat. Wife's Grand Cherokee tows the boat fine. Dealer said it's the trailer. As I research other trucks, Dodge's are leaking and their instrument clusters are a cluster F right now. Fords leak and have all kinds of infotainment issues too in the new 21s. All this technology integration is fine as long as you test test test. I work in aerospace manufacturing so we test components a lot. I've gone so far as to start looking for old 87s that have been restored. No electronics. All mechanical linkages. The good ones are pricey though.

This...and all the leaks on ramtrucks.com...is pushing me to the Tundra. Bulletproof design with bad mpg and boring interior, but at least it’s dry

Ugh...and I was all excited about the 21 F150s. Right now the best candidate seems to be a Tundra, but I despise the interior. GM got our letter yesterday, so we’ll see what the6 offer.

Been researching other trucks while I wait on GM to decide what they’re going to do.. Over at ramtrucks.com, their Rear Window Crack and Leak thread is up to 83 pages. Sounds like Dodge has issues too. One poster is on his 4th service appt and still is leaking.

At least that what they told me... funny how the maintenance records on my.gm.com are not filled in for the last 2 service visits. The count currently is 3 fixes of the spoiler gaskets and 1 reseal of the rear window. I'm not giving them the chance to repair it again. Lawyers are on it.

As of this morning, I've secured attorney representation and notified GM of our intent to pursue a refund. I'll let y'all know how it goes.

This is after 4 repair attempts. This is just rain.

This is disappointing to hear. Waiting on my new rear glass to arrive. I guess they should order 2 more since it's going to crack again in the future. In the meantime, it rained yesterday and now I have another 18 in. wet spot in the headliner. I'm really to the point of having GM take the truck back under lemon law and go get something else.

I really do have to give a shout out to Devin at Guntersville Chevy. He hasn't let go of getting this solved and even had the exterior detailed for me while it was waiting on parts. This issue isn't at all their fault. It's a crappy design and they're the ones having to deal with the issue. It's nice to have a service advisor that truly give a crap. He's a young guy and will do well if he continues to give service as good as I've gotten.

@gemarshThey didn't elaborate on the water leak while driving, but that's my guess too. Did just get a call saying they're replacing the entire back window this time since it was leaking from the sliding window plastic crack that has been previously talked about on here. For the spoiler, my guess is that when the tech over-torqued the spoiler bolts, he damaged the frame of the roof as well, and that's why it won't seal correctly now. Service manager said the spoiler torque specs were a recent notice they received from GM. @bfontenot9 Thankfully yes...31K
