2021 CHEVROLET SILVERADO 1500 Complaints

No check engine light, and my transmission didn't engage gear. I left vehicle off for the night, started it and it worked perfectly fine. Still, no check engine light was on.

Around [XXX] on [XXX] the vehicle shut down with no codes showing or any warning. The weather was approximately 13* f. After many failed attempts to restart, and the electrical systems would not power down as if the vehicle thought it was still running. The only way to get the system to shut down was to disconnect the battery. i had to physically push the vehicle to a safe location. The next morning I attempted to diagnose the issue with no success. I had the vehicle hauled to the dealership from which it was purchased in Idaho to have it inspected. Tuesday morning I received word from the dealership that the engine suffered major failure. This will be the 3rd engine in the vehicle. I am uneasy about the dependability of the vehicle as I have recently discovered that this particular engine is having massive failures all over the country. So much so that the NHTSA has opened an investigation for the purposes of safety. I purchased the vehicle for the main purpose of pulling a snowmobile trailer with snowmobile to the mountains and also to tow my boat and trailer. Both of these activities require a vehicle in which I can depend on. While I am waiting for a back order engine the dealership and manufacturer refuse to lend a like vehicle, leaving destitute. I am hoping that this agency can offer some assistance, and I believe it's important that you are made aware of the hazard that this particular engine possesses. As I previously mentioned this the 3rd engine and As far as I can see this will occur again putting myself and others potentially in harms way because of a known issue. This does not make me feel confident of the safety of the vehicle. Be aware where i live there grades in every direction and extreme weather conditions from season to season.

I was driving and my electric steering locked up. I had it towed to a garage and they reset the computer. I'm afraid it's going to happen again. I'm going to the dealership on Tuesday and I don't feel that I should pay for this since it's a safety issue. I only have 50,000 miles on it.can someone please get back to me. Thanks

Drove my truck home for lunch. Truck drove normal all morning with no warning lights or audible warnings. Went to leave and head back to work. Put my truck in reverse and it would not move. Still no warning lights or audible warnings. After looking online it said that this was common in the Chevrolet speed transmission. It also says the valve body was bad. They also stated that it could lock up the transmission and cause an accident. Luckily I was not driving down the road to find out. When talking with a Chevrolet dealership they told me that the parts to fix the transmission is on backorder. They also stated that the parts may not be available for months. Because the Chevrolet dealership had other Chevrolet vehicles in with the 10 speed transmission with the same issues and could not get parts because of the valve body being on backorder. They also said that the whole transmission being on backorder. This sounds like it's a common problem with Chevrolet 10 speed transmissions.

2021 Chevrolet Silverado Trail Boss with transmission valve body problem. Truck nearly stalled while driving and towing my boat then a huge clunk in the transmission. The truck then rapidly accelerated, down shifted, brief wheel lock up and I was nearly sent in to the ditch with my trailer now swaying behind me. The entire situation felt extremely unsafe and dangerous to both me and oncoming traffic. The check engine light was then on and the truck went in to limp mode. The truck would also no longer go into reverse. I first brought the truck in in October. They finally diagnosied the problem on November 4th, 2024. It is now February 14, 2025 and GM can still not provide me and ETA for the part or for repair. I've opened a service ticket with GM and asked for a buyback as I do not feel safe driving this vehicle any longer. I still do not have resolution with GM or my local dealership.

Tailgate, inadvertently opens. Causing, causing items in my truck bed to be exposed, although I haven’t lost anything while traveling. I have witnessed this occurrence while truck is locked sitting in my driveway, last incident was last night, 13 Feb 25. Also, noticed it when pulling out of a repair shop after getting brake pads put on vehicle. Wife had witnessed it a few months ago while driving back from town. I noticed a recall had been made about Chevrolet trucks and inadvertently opening tailgates. However my truck was not listed as a recall, when I checked VIN. Called Chevrolet garage to see if they could find my VIN on the recall list. Most of the recalls were on the 2500 and 3500 series but it also listed trucks with switch in cab for tailgate to open. I do have an appointment for the problem at Chevrolet garage in the 18th. To fix problem and prevent causing a hazard on the roads.
