2021 CHEVROLET SILVERADO 1500 Complaints

Number 2 cylinder lifter failure. Metal found in oil. Need to replace the engine

Engine failure , early on it had the dod replace. Under warranty and I’m not 100% sure but this time it failed and took out the engine. New rotating system and valves replaced Happened at just under 100k miles With all I’m seeing about these engines I figured I’d report it.

About 2 months after bringing the truck in for the engine recall, my oil cooler blew up and I required that to be replaced, along with the radiator and hoses.

At 12,000 miles a lifter malfunctioned. It was repaired by my local Chevrolet dealership by replacing lifters on one side of the engine. The delearship also changed the viscosity of the oil. At 64,000 miles roughly another lifter malfunctioned and needed replacing. Had I been on the highway at the time of failure it could have posed a risk for the safety of my family and others on the road. Each time the check light was flashing at the time of the incident.

Truck started violently shaking while driving 70 mph on highway. Check engine light, service electric parking brake warning light, TCS/ESC warning light, started flashing on tachometer. Check engine light remained on when truck was restarted later. Chevy dealer service department reproduced problem and found broken bits of metal in the oil filter. Engine is shot. Likely caused by truck's Dynamic Fuel Management system. Dealer advises only option is to replace engine. Truck was up to date on all service maintenance.

The check engine light came on and my engine would stall sometimes, it would stall at start up so no safety issue. I took my truck to the dealer a week later where they said a wire was corroded from rubbing on something causing the issues and that it was a common issue.

My husband was driving his 2021 Chevy Trailboss when it went into limp mode. It had to be towed to the dealership and it was uncovered that his truck was throwing out codes P0700 P2732 which is a known issue with this truck, resulting in internal valve body hydraulic failure. Since his vehicle is at 70k miles, and over the 60k, the dealer is pushing back and trying to say they don’t have to cover it. GM states that we should pay and then submit a reimbursement form. This is a $3800 fix. This is not our responsibility and this is unsafe. This should be a safety recall for all vehicles of this make, model, and with this transmission. Additionally, he had to have his engine replaced on this truck (we bought it brand new in 2021) with only 10k miles on it. This truck should not be built anymore and anybody facing these issues should not be held liable for them. This is a manufacturing issue and it is only one company’s fault, General Motors!

As of august 19, 2026 my engine suffered a catastrophic failure with code P0016 which is cranckshaft camshaft lifter failure. Engine will be replaced. Currently at the dealership for replacement. Had the truck for 2 months and I’m requesting that GM fully replace my truck with a different one because I’m sick of hearing all the failures going on with the 6.2 engines. Such as my truck.

I own a 2021 Silverado Trail Boss LT with the 6.2L V8. I purchased the vehicle new at Classic Chevrolet in [XXX]. In XXX, it experienced what I can only describe as engine failure. Severe knocking, loss of power, rough idling. I contacted the dealership as it was under warranty (it had approximately 45k miles at the time). They towed the vehicle in and performed repairs. I do not have service records but the repairs totaled approximately 12-15k dollars and involved several engine part replacements. I received the vehicle back after about 2 weeks. I later learned of the factory recall that was issued by GM affecting my truck and took it in for inspection. This XXX5. It was inspected and passed. They did replace the oil to a higher weight oil as recommended. In XXX it experienced the same issues as before. This time while driving on freeway. Sever engine knocking and loss of power. As I was on the way to work, I drove straight to the dealership to drop it off. After inspecting, they determined it warranted a replacement engine under the original recall. They kept the vehicle about 3 weeks and returned back to me in early XXX. It has been driving fine since then, but I am worried the replacement engine may have the same defects as the original engine.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while attempting to start the vehicle, the engine failed to crank. The contact originally suspected a battery failure, as the vehicle had recently been involved in an accident that left the passenger-side mirror damaged with exposed wires. While driving at 70 MPH, a semi-truck sideswiped the passenger-side of the vehicle, causing a dent on the front door and a fractured side-view mirror. The semi-truck driver did not stop, and the contact's son drove the vehicle to the nearest exit. No air bags deployed, no warning lights illuminated, and no injuries were reported. A police report was filed. The vehicle was initially towed to a collision center, where it was determined that the battery was not the cause of the starting failure. The vehicle was then towed to a dealer, where it was diagnosed with camshaft, timing belt, and actuator failures. Upon removing the camshaft, metal shavings were found inside the engine, and the dealer determined that the engine needed to be replaced. The contact associated the failure with NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the VIN was not included in the recall. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 91,733.
