12. Filed Apr 29, 2026Failure Apr 18, 2026Sturgis, SDEngine

    we have had no issues with this vehicle at all. then one day notice a ticking in the area of the valve covers. Sounded to be more on drivers side. Thought maybe just the oil was low which has never happened before. Oil level was fine. I always change oil on regular intervals and there were no check engine lights and engine continued to run fine with no loss of power or ticking changing. It was our only vehicle so we had to continue to drive that day. Wife was driving and said vehicle shuddered and started sounding funny and check engine light came on she was able to drive back home. Now ticking is worse with a clucking rattling sound now coming from oil pan. After some internet searching it very much sounds like issues many others are having with the 6.2l GM engine.

13. Filed Apr 28, 2026Failure Jul 15, 2025Saint Marys, OHAdaptive cruise control, Automatic emergency braking, Vehicle speed control

    At 70 mph the adaptive cruise control system applied the brakes hard enough to engage the abs system even though my lane of travel was clear. There was a car on the exit ramp to the right applying their brakes not in my path that I believe my vehicle picked up. There were several vehicles behind me and it almost caused an accident. There needs to be a way to disable the adaptive cruse on this vehicle for safety concerns. This has happened to me on multiple occasions and I reported it to the General Motors hotline with absolutely no feedback on the issue.

    P0304 and P0306 misfiring and compression on both cylinders is 0. Both lifters have broke and collapsed. It started with a noise, once checked by the mechanic, we were told the lifter was going bad, before we could get it repaired it completely broke and that is when the check engine light came on and went off repeated times. At this time it is pouring out black smoke when driving and must have a complete engine replacement. The replacement work has been quoted for $10479.57.

17. Filed Feb 1, 2026Failure Oct 31, 2025Fair Haven, NJEngine

    I suddenly noticed a noise coming from the engine that sounded like a noisy lifter and stopped using the car after hearing it. The next day I called Circle Chevrolet to check and verify if they could check the car and do any work required under the CPO Warranty. They advised that they could since they were part of the GM Family and could do any work required under the CPO Warranty. I then arranged to have the car towed to Circle Chevrolet to prevent any further damage, that was on Oct 20, 2025. The CPO Warranty was due to expire on Oct 27, 2025 due to time, not mileage. The dealership advised that the vehicle would need to be examined by one of only 3 qualified mechanics in their shop who could do this evaluation and determination if the issue(s) were covered under the CPO Warranty and it would be about 3 days before they could have one of their 3 qualified technicians check the car. The Service Adviser called me back on October 22nd, 2025, and advised that Cylinder 5 had noisy lifters and that they would be changing out the engine with a newly rebuilt engine, all under the CPO Warranty. The Service Adviser said it would take 3-5 days to get the replacement engine in and then about 2-3 days to replace the engine. However, less then 24 hours after getting my car back, the check engine light came on, which was not on when I had the car towed to the dealer. They said the catalytic converter needed to be replaced and said it would be ~$6000. They refused to cover the replacement even though the catalytic converter was damaged due to a combination of the engine problem/defect and the testing and installation work performed by the dealer. I reached out to the dealer and GMC and they refused to address the issue and would not provide an itemized estimate to replace the catalytic converter and refused to return my phone calls I made to both the Service Adviser and Service Manager. The GMC representative I spoke to refused to address the issue as well.

    The transmission is shaky, Lower gears the truck seems to fight it way into the next gear, I feel this is happening around 3 to 5 gears. One garage told me the power converter was failing. I changed the transmission fluid and filter and it got better, but sill, this is an expensive truck. This is power train, this should be covered to 100,000 miles.
