I am writing to formally report a persistent and dangerous manufacturing defect regarding the rear window and seating assemblies in my 2020 Chevrolet Silverado. I have already had GM replace the rear window in 2023, it needs replaced again now in 2026. The rear window seal is failing, allowing a significant amount of rainwater to leak into the cab. Because of this ongoing water intrusion, the structural base and brackets of the rear seats have developed severe rust. Furthermore, I am deeply concerned that this constant moisture saturation is creating an unseen mold hazard within the cabin, which poses a direct health and respiratory risk to my passengers.This leak also risks damaging sensitive electrical components and wiring harnesses located under the rear seats and trim panels, potentially causing short circuits and sudden failures of critical safety systems while driving.Many other owners of this generation Silverado have reported identical issues, including cracked plastic frames around the sliding rear glass that cause the leaks. Because this defect compromises vehicle integrity, creates a risk of electrical failure, and poses health hazards from mold, I am requesting that the NHTSA investigate this issue as a potential safety defect requiring a manufacturer recall.

Sliding rear window leaking, causing mold and ruined seats. Had it "fixed" in 2023 only 3 years of owing it. Now here 3 years later the same issue is occurring and they're not willing to make it right. Mold causes a safety hazard for my children and anyone in my vehicle. My truck only has 30,000 miles on it and I shouldn't be having this issue
NHTSA complaint #11737946 — an unverified report by a vehicle owner.
These are two separate incidents. The first one is the seat moves to the left or to the right given the direction of the vehicle. The other incident was when I was reversing into a parking spot. The gear shifted out of reverse and just was in a floating stage. I then had to put it back into reverse to continue it did it twice
NHTSA complaint #11731884 — an unverified report by a vehicle owner.
The car seat anchor system is very poorly designed and extremely difficult to use. I just spent an hour trying to ensure the seats for our grandchildren are installed correctly. The upper anchors are poorly placed, difficult to access and do not inspire confidence the seats will be secure in the event of an accident. This is after I had to take the truck in for a warranty claim because the lower car seat anchor on the back seat passenger side was covered by factory upholstery and could not be used at all. It’s very frustrating when one attempts to comply with safety regulations but poor design inhibits the proper installation of car seats.

I dropped an ink pen between the drivers seat and the center fold down seat. While attempting to retrieve the pen I reached between the drivers seat and the console just forward of the seatbelt connector with my right hand. When I pulled my hand out a sharp piece of metal on the seat frame sliced the fatty portion of my hand below the thumb. There isn’t a guard to protect the hand in the event one reaches between the seat to retrieve an object. I also found the same sharp piece present on the passenger side seat between the seat and the center console. I took the vehicle to my local dealer and the service manager also noted the sharp portion of the seat. He too, sliced his finger while reaching between the seat and the console. I did warn him beforehand as to what could happen. He suggested the vehicle be brought in for service. This is not a functional issue. This is a design, material flaw issue which has the potential to created injury.

Several times mi wife and I have been close to provoking an accident due to the driver seat not been able to go up for my wife to see well over the dash nor will it go down for me to see the gages well. My wife has been stretching to look over creating neck and back pain and I have lowered my head down taking my eyes out of the road close to provoke accident several times.

Powertrain failed and vehicle would no longer move. Engine would rev up, but truck would not move in any direction, almost like the transmission had gone into neutral. Powered the vehicle off, then back on, and it violently jerked, but was enough for me to get to the shoulder. Afterwards, got the vehicle checked out with a scanner, there were no check engine codes coming up, nor were there any lights on the dash. When they checked the transmission oil, there was a lot of metal flakes, which will require a transmission change. Eletric seats also do not allow any movement, making it very difficult when others try to drive the truck.

NHTSA complaint #11488001 — an unverified report by a vehicle owner.
My driver’s seat started moving slightly then by the end of the day it was rocking back and forth at least 2 inches. The dealer said it’s not under warranty and it would be $1,200 to repair it. I had it welded but the weld didn’t hold. I am afraid this is a big safety hazard and should be covered especially since the truck is only 5 years old. I only weigh 200 lbs and I am the only one who’s ever driven the truck. There is no reason the seat should be broken. Consumer stated vehicle not included in the recall.

Have been experiencing a disconcerting side to side driver seat movement when navigating corners. Had truck looked at as there have been numerous online posted issues with this issue. Upon inspection, was told the seat frame was broken at a weld point and seat would need to be replaced. Also told they have replaced "Many" broken seat frames for the year and model of my Silverado. Note, this truck has only 16,000 miles on it and is maintained like new.

The drivers seat moves while turning. It feels like the seat is sliding when turning then there is a "catch" and a sudden stop in movement. While driving and making a turn the feeling the seat will come unbolted from the floor is a unnerving feeling to say the least

THE SEAT SHIFTS DURING A RIGHT AND/OR LEFT TURN. I WAS TOLD AT THE DEALERSHIP, THIS WAS A PROBLEM, HOWEVER THERE HAS NOT BEEN A RECALL. I JERK WITH THE SEAT DURING THE TURNS. I AM AFRAID THAT IF I HAVE AN ACCIDENT OR THE TRUCK ROLLS OVER IN AN ACCIDENT THE SEAT WILL NOT BE SECURE AND MAY CRUSH ME OR THE DRIVER.
