ENGINE, FUEL/PROPULSION SYSTEM
I was traveling on a 55mph road. My Chevy Silverado started to shake and lose propulsion. I pulled off on the side of the road. In idle it shook. The dealership was one mile to my south. I turned on the hazard lights and went to the dealership. I could only get the vehicle to 45mph as in shook very bad the whole way. It felt as if the engine was going to explode the whole way there. The vehicle was taken to the dealership where it has been initially diagnosed as a bad lifter.

POWER TRAIN, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
Vehicle braking does not work- since new- dealer said it was funcitioning- sometimes you will get the warning and other times it does not and it never brakes. Transmission- i received a letter to bring truck in to have a software update for modulator valve wear....which was performed...since that time the stator and the torque converter were replaced in September/October of 2025. it was in dealership approx. 6 weeks for the repairs. Since that time i have had the vehicle roll forward when in reverse and pedal depressed, I have had hard shifts when shifting into gear at a stop, severe enough to lurch the truck forward and break traction....i have started having three to four downshifts very abrupt and very hard when decreasing speed. Dealership does not act like they want to do anything about it.

I am submitting this complaint regarding a 2021 Chevrolet Silverado 1500 Trail Boss 4WD with the [6.2L V8 (L87)], VIN [XXX], 101,000 miles. The truck was assembled in Mexico in XXX, about six weeks before XXX, just outside the build range of GM recall 25V-274 (N252494000, Engine Failure). On 10/2/2026, [XXX], [XXX] a certified GM dealership, diagnosed crankshaft and lifter failure, matching the recall condition. Codes: P0300, P050D, P0016. The truck was shaking violently, the ESC and emergency braking system failed, reducing engine power. GM's Part 573 filing attributes the defect to out-of-specification crankshafts and identifies a Mexico-based crankshaft supplier. I ask GM to confirm my engine's build date and crankshaft source. A six-week gap in build date should not exclude a truck with the same failure. Engine failure can cause sudden loss of power while driving, a safety risk. The dealer quoted repairs of up to $10,292.00. I request: That GM cover the repair in full as a goodwill adjustment. That GM and NHTSA review expanding the recall population to trucks built near my date. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This vehicle's engine failed on a high-volume roadway in [XXX] which resulted in a significant safety issue. The vehicle was taken to a certified Chevrolet dealership in Scottsdale (Van Chevrolet) whereby the engine in this 5.3L V8 was replaced due to catastrophic engine failure with the lifters being the suspected cause of the failure. Aside from the $10,400 cost of the remanufactured engine replacement, I have had considerable discussions (live and written) with GM Arizona and Corporate representatives outlining the issue(s) and filing formal complaints. These have gone relatively unheeded... Unfortunately, this is the second 5.3L V8 engine failure in one of our GM vehicles as I will be filing yet another formal complaint under separate cover for a 2021 Tahoe 5.3L V8 which had an engine failure requiring new lifters. I am not done yet as I have an appointment tomorrow for what appears to be, a third Chevrolet vehicle with a 5.3L V8 engine lifter failure. Depending on the outcome of this service appointment, I may be filing a third safety complaint regarding the GM 5.3L V8 engine. In my opinion, the NHTSA should absolutely open an investigation into this engine in the same manner that you have a formal investigation/recall in effect for the 6.2L GM engine as based on two personal experiences, the safety of the driver and passengers in these vehicles is compromised due to what appears to be significant engineering and/or manufacturing issues on the part of General Motors. Thank you for your consideration and I am free to discuss in further detail at [XXX] or [XXX]. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I opened my passenger front door to load and the tailgate opens and closes by itself but doesn’t and remains open. I physically shut the tailgate and it opened again by itself. I started my truck to see if it would stop. It didn’t stop until I put my truck in reverse to back out of the garage. After I backed out and the tailgate stopped open. I closed it and the tailgate will not open by pressing the button on the tailgate. It will open if I use my key fob.

Vehicle has a bad valve body which was confirmed by the dealer. Driving down the street and the engine went from 3 to 4 gear and the rear wheels locked up. Also when coming to a stop the truck jerks so bad it snaps your neck. GM has major problems with these trucks and knows the problems and keeps issuing bulletins however they have a massive backlog of orders for parts to fix these trucks which leaves people's trucks sitting at service centers for months waiting for backordered parts

Pulling out from a stop sign, a loud bang came from the transmission, and rear wheels momentarily locked up then truck acted like it was in neutral. Truck was able to drift to side of road. We called our GM dealer, and they told us that our warranty had expired. We had the truck towed to our certified repair shop. After review of truck, the mechanic called and said the output shaft of the transmission broke. The mechanic called GM and asked if there was any financial assistance for this problem and they said no. He ordered a transmission through GM, and we had to pay for transmission upfront. The amount was 6627.05. Since then as we researched, we found out that GM has a Goodwill assistance program that would have helped us had we known to take it to a GM dealer. With two phone calls, no one guided us on doing that. Our truck has only 38,000 miles on it and when I called GM, they said they would have been able to assist us if we had sent it to a GM dealer. We tried to explain that no one gave us that direction and now it is currently being repaired at our local garage. Can we get any assistance at all with this claim? We would appreciate any assistance you could provide for us. Thank you [XXX] and [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

According to 2 mechanics- including a body shop - the frame has prematurely rusted due to: TSB 19-NA-255 - Wax Coating on Frame Peeling, Metal Shows Corrosion/Rusting There's so much damage to a 2021 truck, that it may not survive this winter. The frame welds are breaking due to the lack of frame protection. I asked my dealership, Lamoille Valley Chevrolet 868 VT RT 15E HYDE PARK, VT 05655, on two separate occasions to check for damage. One time they made no report, the second time they told me it was normal wear and tear. I've been told trucks 20 years older than mine, are in better condition. There was no protection for this frame.

Around 60k miles my truck started shifting rough and at odd times. Then it went into “limp” mode. I took it to the dealership and they replaced my battery and a solenoid. I asked about the transmission and they told me it was because it was in “limp mode”. I’ve continued to have issues with it then a couple of months ago while driving to work at around 60mph the truck harshly downshifted into a low gear causing the rear tires to break loose on the wet roads and sending me into an extended spin. I had the truck towed home and then to the local dealership. After researching, I have found that this is very common with the same vehicles in this year and that there are multiple recalls to address the issues. Unfortunately my VIN is not included. I believe the needed repairs and the associated costs should be GM’s responsibility under special coverages: N242454441 and N242454440-03
