2021 CHEVROLET SILVERADO 1500 Complaints

Belt tensioner/idler pulley began chirping during warm up after starting engine. Noticed serpentine belt was beginning to fray on edges. Dealership confirmed the pulley failed prematurely and caused the serpentine belt to be damaged. Dealership replaced pulley and belt. It was just after warranty expired. The belt is supposed to be replaced at 100,000 miles as routine maintenance, but the failure of the pulley, which the dealer informed me was also premature, but common, was not covered under warranty. Power steering was lost one time in park and a message showed on the dash, but went away after restarting the vehicle.

At 62000 miles, I was having a transmission problem but had no check engine lights associated with the issue. The day I took it to the dealership for the transmission, the check engine light came on for the first time ever when I started the vehicle. The dealership first said it was a faulty solenoid on the purge valve, replaced that part, but it didn’t fix the problem. The dealership then said it needed a new fuel pump control module, which was heavily back ordered due to demand. I needed the vehicle because it had already been at the dealership for a transmission replacement for many weeks and is my only transportation. The dealership told me other vehicles were there for the same problem, parts were on a national back order and being rationed to dealerships around the country. They could not provide an estimate for when my vehicle would be ready and pushed me to trade in my vehicle as a solution. The sales manager offered a very low trade in value, told me I couldn’t get the part faster by purchasing it myself, and was very pushy. She said my vehicle was devalued because it didn’t have the fuel pump control module needed for the check engine light to turn off, and had a history of transmission problems (even though it just got a new transmission). I got frustrated and ordered the new GM part from summit racing and had it on my doorstep in two days. I took it to the dealership and all of a sudden they had received a shipment of this part, and replaced the faulty one in my vehicle. Their repair resolved the problem, but I still had reliability concerns. Despite all repairs being completed, the sales manager said the vehicle trade in value remained unchanged. It was a complete nightmare and I felt my vehicle was being held back from repair resolution to convince me to trade it in for a new truck. I kept my vehicle and extra part I ordered in case this happens again.

Transmission began shifting hard over between 60500 and 62000 miles. Dealership test drove and confirmed it was not normal. The transmission pan was dropped and contained metal shavings and bits. Dealer replaced transmission. During late February 2026, I began noticing some hard shifts again, but am hesitant to pay another $699 diagnostic fee and replacement transmission cost because I feel I am wasting money on a poorly designed and unreliable transmission. I don’t feel confident relying on this vehicle for transportation to medical appointments anymore.

Window switch failed and I was unable to roll down the window. Dealer confirmed and performed repairs. Problem occurred on a dry day with no previous issues and the dealer stated it was manufacturing defect with the switch.

The contact owns a 2021 Chevrolet Silverado 1500. While driving 43 MPH, the message "Brake Failure" was displayed. The contact then lost control of the vehicle, and the vehicle drove from the right side to the left side of the road, the vehicle drove off the road and crashed into a ditch before coming to a stop. The driver had not sustained any injuries. There was no property damage. The air bags did not deploy. The check engine, the ABS and several unknown warning lights were illuminated after the failure. A tow truck driver who was also a mechanic inspected the vehicle and informed the contact that the driver's side front suspension had fractured from the upper ball joint and the wheel was folded in underneath the vehicle. The vehicle was towed to the dealer, where it was being diagnosed. A Police Report was filed. The manufacturer was not notified of the failure. The failure mileage was approximately 98,000.

The vehicle involved is a Chevrolet Silverado 1500. During a collision, the vehicle sustained a front-left (driver-side) impact which caused it to spin and subsequently strike the rear. Despite the severity of the initial impact and secondary rear collision, the Supplemental Restraint System (SRS), including the front and side airbags, did not deploy. The failure of the airbag system increased the risk of injury to all occupants, including a minor child. Without deployment of the front or side airbags during a front-left impact and secondary rear collision, occupants were exposed to direct impact forces that airbags are designed to help mitigate. There were no airbag or SRS warning lights, dashboard messages, or other indications of a malfunction prior to the collision. The concern regarding the airbag system arose only after the incident occurred. Following the collision, the vehicle was inspected by law enforcement and insurance representatives, and documentation is available. The issue has not been reproduced, as it occurred during the collision event.

P1098 engine coolant control valve Engine light comes on and truck says reduced power. Then went off. Back on again

I bought this Truck in December 2023 from Honda of Ocala as a used vehicle it had 59,000 miles when I bought it. In October 24 it started smoking from the exhaust one morning as I was leaving work. I have always changed the oil on time and taken good care of the truck. I found out the lifters had failed and Honda of Ocala replaced all of my lifters on both sides around $4,000 in repairs the truck was at 73,000 miles at this time. A few months after getting it fixed the truck started smoking again and going into limp mode at 81,000 miles. I still owe $30,000 on this truck but can’t afford to keep fixing it and can’t afford to trade it in and go negative on it.

I just bought this truck off a used car lot certified dealer and I noticed the engine light on then the truck would hesitate to start and I know the battery is dying so I looked it up and I got a recall on 2021 Chevy Silverado just like mine just wondering why mine is not under recall or why won’t mine get fixed but everybody else is the same year in the same problems can get fixed. I think mine should be fixed.

A recall repair was performed on my vehicle at approximately 157,000 miles. Approximately 4,000–5,000 miles later, the transmission failed. The vehicle entered reduced power mode and became stuck in gear while driving. The dealership is recommending full transmission replacement but will not provide written explanation for why the failure is not related to the recall repair. I am concerned the recall remedy may have failed and that this condition poses a safety risk.
