| Apr 2025 | ENGINE | While driving at 35 mph my check engine light, Service Parking Break light, ABS Maintenance light all came on and my truck lost power to a point I could not go over 10 MPH. It started chugging and running very rough. Fortunately I was close to home and got it in the driveway. I called the dealership to set and appointment, tried to drive it down my driveway and couldnt get it over 10 MPH. I called a tow company to take it to the local dealer I purchased from. After a couple days the dealership called and said there is a lifter problem but wasnt fully into the engine to see if there was more damage and would call me once more testing had been done. I have photos of the tow company tow bill ($169) and a photo of them lowering the bed to put the truck on it to haul to dealer if needed. | Crash: No Fire: No | Unknown |

| Apr 2025 | POWER TRAIN | Transmission jerking violently while driving at low RPM 1000-1500 RPM. Occurs daily. Shudder and vibration as vehicle is slowed approaching stops. Effect and feeling is unsettling to driver and passengers. Can be recreated but is also intermittent at times. Dealer has avoided fixing as it is not 100% consistent. Asking me to drive until failure which is unsafe and could lead to accident or stranding. | Crash: No Fire: No | Unknown |

| Apr 2025 | POWER TRAIN | The transmission either shifts hard or momentarily locks up when downshifting and then shifting back up into high at 50+ mph. Check engine light comes on, tow haul mode is not available, engine rpm's increase dramatically. Transmission will begin shifting normally after a engine stop, but check engine light stays on, and tow haul mode is not available. Cycle continues. The hard shift before the check engine light comes on and transmission upper gears are locked out is very unnerving, especially with a travel trailer behind you at 65 mph. I no longer fell safe driving the vehicle. I am requesting assistance from the dealership on this truck with less than 49000 miles. The "flash for the transmission" recall was done several thousand miles ago. It only masks the situation. This is not acceptable, nor safe. | Crash: No Fire: No | Unknown |
| Apr 2025 | ENGINE | I purchased this vehicle brand new is 2021 with the 6.2 liter engine. I have had all the regular maintenance performed as scheduled with 90% being done at a Chevrolet dealership. My truck has around 90,000 miles on it and now the engine is out. It started with showing low oil at 50% oil life left. When I took it to have it checked, it was 3 quarts low on oil. I did another oil change and was told I had to start an oil consumption test in order for them to review the issue. I had it checked every 1000 miles. The first and second check was fine. The third check was one quart low. They took it in and found that the spark plugs were oil fowled. Upon further investigation, they found that the cylinder walls were scored and had oil bypass in the cylinders. I have done everything right with this truck. Took care of it in all the ways I was supposed to. There is no reason what so ever for the engine to have gone out at 90,000 miles. There has to be more to this. I have looked it up and other people are having the same issue with the same engine. Why is nothing being done about this? | Crash: No Fire: No | Unknown |
