My safety system service warning comes on for about 30 seconds and then goes back off. This has happened about 4 times now. The transmission causes my truck to shake randomly. My pulley is going out and the local dealer said they wouldn't replace is under warranty(even though my warranty was still is effect) because they said it looked like someone sprayed tire cleaner under the hood(I bought it from the same dealership that I took it to for this service.) The brake seem to shake already when coming to a stop. They seem as if they are wearing prematurely.

I have major rust on the frame I just purchased the truck. Is their a recall on 2021 Silverado frames1500 custom.

While vehicle is in 4-wheel drive or 4 auto or 4 L. It makes a grinding whining noise! I have contacted the dealer Newberry motors of Newberry MI 49868. I asked them about a service bulletin I saw on the noises I am hearing, and I was told service bulletins are only assigned to a vin number and not groups of vehicles. which is a lie!!! SO THE GRINDING NOISE IS BAD WHEN IN 4 WHEEL DRIVE. PERIOD. DOES NOT MAKE THE NOISE WHILE IN 2 WHEEL DRIVE. THANKS FOR ANY HELP THAT CAN BE PROVIDED!

1 and 7 lifter failure occurred. Truck failed while driving on a congested highway putting myself and others at risk when speed was speed was reduced and truck eventually stalled. Truck was serviced by local dealer and confirmed lifter failure. KNOWN ISSUE!!! NO WARNING PRIOR TO MALFUNCTION.

I had a head on crash on 2/14/23. The other driver was moving in excess of 50mph. The hit was center of the front bumper pushing the bumper and radiator in to the engine compartment. No air bag deployment. However the Onstar system activated immediately.

ESC failed. The 2021 Chevy Silverado (39495 mi) began to shutter and a slight bouncing of the rear end. The ESC light came on the service ESC warning on the dashboard then the check engine light began to blink at the same time the parking brake light came on. The dash warning switched to have parking brake serviced. The truck as best as I could tell applied the parking brake several times for no reason while at highway speeds and traffic on all sides. All warnings stopped when Auto engine shut down at exit ramp light. Previously brought into dealership for “Service ECS” and “Service Power Steering Drive With Care”. I was told “ unable to replicate “ (23194 mi). Vehicle was returned to me. They did confirm the dash warning was stored in the computer. I do not believe any warning (blinkers) or brake lights came on to warn vehicles behind me of the rear brakes being applied by the ESC.

The 2021 LT Trail Boss with the 5.3L engine started a really rough idle, engine knocking, random misfiring, had Service Emergency Brake, Service ESC messages on the display, check engine light and several other dash warning lights. The dealer diagnosed the truck with lifter fail apart (failure), intake valve push rod bent, and PCM failure. Odometer reading 19,368 miles.
