Rear window leaks water into the cab during rain, snow, car wash, etc. GM refuses to abide by comprehensive warranty to fix the issue, and my dealership wants to charge around $1,000 just to apply sealant. Water goes into and behind the rear seat (where my child sits) and goes to unknown area. Water can cause rust, mold, electrical problems, or any other number of issues. I noticed it around November of 2024 but I don-??t know how long it has actually been occurring for. When researching this issue, appears to be relatively commonplace for my year and style of vehicle. Even the GM techs at my dealership acknowledged it is a recurring issue that may require MULTIPLE visits before getting a permanent solution (replacing the entire window).

2020 Chevy Silverado 1500 8L90 transmission failure at 40,000 miles and I am now at 90,000 miles with the same issue. I have been working on this truck tirelessly tried to fix the transmission. I-??ve had 3 transmission fluid replacements and a full torque converter replacement. General Motors knowingly sold these models to consumers when the transmission was faulty and underperforming. It shudders, shakes, and slips while driving. It-??s almost caused me to get into a few accidents. I just want compensation and to be a part of the class action lawsuit they are being filed upon.

Dealership attempting to sell a vehicle with an open recall was more than prepared to let me drive and potentially sell a vehicle with a recall open causing the rear tires to randomly lock up. Made problem known to salesman and said they'd take it off the market. Now, they lowered the price by $2600 as it was previously listed at $25,571, now listed at $22,971. Listing still not down.

While driving, the vehicle began experiencing hard shifting. When I attempted to accelerate to pull over, the vehicle failed to respond and instead sounded as though it was in neutral. Additionally, when I tried to bring the vehicle to a stop, it took longer than usual, as if the wheels were locked.

The 10 speed transmission suddenly downshifts when slowing down. It goes from like 8th to like 3rd suddenly and the rpm-??s shoot way up. The wheels do not skid on pavement but will be an issue when the roads get slick here in West Virginia. This is a serious safety concern. This has happened many times since I purchased the truck. The dealer in the past has told me the transmission needs flushed. But now I-??m seeing that there is a recall for new transmission software. I would like to have this update please before the roads get slick from snow and ice.

The back window is leaking water into the cab. Water enters the cab any time it rains or when washing the truck. This water is creating a damp environment by soaking into the back of the seat, the carpet, and the headliner, creating the potential for black mold. Immediately after purchasing the truck, the dealership had me bring it back in so they could fix it. Ever since the repair from the dealership, the window has continued to leak at the same rate that it did before the fix.

There is a known issue with known leaks at the rear spoiler/ 3rd. Brake light. Due to this leak, there is an odor in the vehicle caused by mold or mildew which is creating breathing and alergy issues. I recently had open heart surgury and this is starting to effect me to the point I can not be in my vehicle without the windows rolled all the way down. And I go into sneezing fits wich is a safety concern

Our 2020 Chevy 1500 Trail Boss was waiting for an ordered instrument cluster at service department. The surveillance camera, film the vehicle catch on fire after being parked for 2 days. The smoke started from the inside, and the vehicle engulfed in flames until the fire department came. After the fire was extinguished very little was left of the vehicle. Basically a frame and engine was the only thing left. The vehicle had a little over 70k miles.

The rear third brake light spoiler leaks causing damage to my headliner and vehicle. I have researched this and it appears to be a known issue to GM. However, GM is saying that my vehicle is not affected as of yet. I had an estimate completed on the vehicle by a local body shop. They believe the issue involves the spoiler assembly nuts not being properly tightened and sealed by the manufacturer. A repair will cost approximately $593.63.

The DEF system tank and heater tube/wiring assembly need to be replaced due to the wiring melting. There should be larger wires or a fuse to prevent this. The system is tied to the Emission Controls system in the vehicle. When this happened I was warned on my dash display I had only 165 miles remaining at 65mph, and presumably slower thereafter. I live in Alaska, we travel long distances, sometimes in extreme cold temperatures and always far from help; even cell service if away from urban centers. I find it unacceptable my truck can decide to strand myself and/or family (3 children under 5) based on emissions, not run-ability. The temperatures in Alaska have been severely cold a couple weeks ago when this issue came up. The issue is confirmed by the dealership and is a known issue in the diesel community. Apparently it is a known issue for diesels in cold weather. Diesel is common in cold weather so the issue is perplexing at best. The vehicle has never been inspected by any one other than myself, a mechanic and the dealer. There were no warning lamps, only the dash warning the emission system needed service.

Rear window leaking like a small stream in regular rain. It-??s going down behind seats and carpeting and headliner staining worse and worse and I am worried about black mold being created. Husband has lung issues and that can be verified by our physician. We have told Jenkins chevy in Venice florida 5/4/22, 3/20/23 and now living in TN spoke to Champion Chevy in Johnson City on 9/29/23 and 1/5/24..it-??s getting worse and as we are out of warranty no one wants to help. We never received any bulletins on my chevy site and it-??s not anything you would normally notice but now we smell the mildew smell back there because it is getting worse. Please help us before we get ill from this awful leak. This is my first Chevy pick up I have purchased in my lifetime. Possibly the last..

The rear power sliding window in my 2020 Chevrolet Silverado 1500 LT leaks whenever it rains. The leaking water enters the cab and runs down the back interior wall of the crew cab and saturates the insulation material and the carpeting on the floor. The moisture has caused the seat brackets that attach the seat to the truck to rust and it has also caused mold inside the cab. I purchased a DIY mold test kit and it was positive for mold. My kids and I have allergies and this is causing issues with our health and if it continues it could cause serious health problems. This known issue of the leaking rear window is very widely discussed on many different gm truck forums and internet sites yet gm will not take ownership of this obvious problem.
