ENGINE
Took it to the dealer for the L87 recall back at the end of April 2026. GM stated that my truck passed the inspection and “upgraded” my oil to the new 0w-40 oil. Now 8-27-2026, 6500miles after the inspection. Driving to work in the morning, and my engine failed. What I believe happened was a lifter got stuck and the engine shook and all lights on the dash were flashing. Vehicle is currently at the dealership and they are saying the “special” warranty does not cover this failure. Which to me is completely unacceptable. Because for 72,900 miles I never had an issue with the truck. But 6500 miles after they changed the oil to the thicker oil now I have an engine failure.

ENGINE
The truck had been driving fine, no dash lights or warning messages appeared. It is available for inspection upon request. My family was at risk if this had happened on the freeway as we had been out just hours earlier. We attempted to start the engine like normal and there was a loud pop or bang and a sound like something dropped and it made loud revving sound never started up again. The initial confirmation by a certified mechanic is to be engine failure. They did not do an in depth diagnosis yet to determine if "the top valves dropped or bottom of the engine connecting rods to the crankshaft". THIS ISSUE ALL ALIGNS WITH THE CURRENT RECALL OF ENGINE FAILURE AS WELL AS THE MAKE. MODEL AND YEAR OF OUR TRUCK. But the dealership Bruce Lowrie Chevrolet says our VIN number does not qualify. Again the issue, make/model and year are all associated with the recall. We are in desperate need for our VIN to be added to the recall as it is fits all the details required.

ENGINE
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.

ELECTRICAL SYSTEM
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.

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.

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!

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.

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.

STEERING, ELECTRICAL SYSTEM, UNKNOWN OR OTHER
When I put the pickup in park, I get a message that states "Shift to Park". The pickup is completely stopped, the gear shift indicator is in "P". When I get out of the vehicle I get two loud two-horn alerts indicating that the pickup in not in Park, when in fact it is. Doing some research, I have seen that this is a common problem for GM vehicles. The console shift vehicles are actually involved in a class action lawsuit, while the steering column shift vehicles are not.

ENGINE AND ENGINE COOLING
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.

Currently had my engine go into "limp mode" after checked engine light came on with code p1010. The coolant control valve is what is the problem, and GM/Chevy has issued a special coverage on this known part for my year make and model (Bulletin N252508341). However, according to the dealership, my VIN does not qualify for this known issue, regardless of my faulty part matching the special coverage for the year make and model of my vehicle. Now I'm stuck paying for the empty promise from Chevy.
