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.

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.

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 V8 engine on our family's 2019 GMC Yukon Denali XL check engine light came on and began ticking while taking our daughter to college in Montana. The dealer informs us the engine has probable lifter failure and will need to be disassembled to diagnose additional issues. The estimated repair costs are from $3,000 to $10,000+, may require a new engine, and we will be without the vehicle for almost two months. We are incurring additional costs such as lodging, airfare to fly home, costs for an additional car, and storage for a travel trailer that must remain behind. The warranty on our vehcle expired last year. The vehicle has been consistantly serviced at our local dealer. Research and discussions with other GM customers inform us this is a known issue for our year and that a recall was issued for vehicles for 2021 to 2025.

Driving down the interstate and engine gave out, started shaking, and started losing speed. No warning, in the middle of the night with two young kids in the car. Sat on the side of the highway in the pitch dark. 2 days later truck was towed but the GMC had no one to look at it. Had it towed again and that GMC dealership said it was the engine and they see it all the time with that year/make/model. $16,000 for new engine. Contacted GMC and they stated that year is not included in the recall. Research this issue on google and most owners of the same year/make/model have the same issue with no help to solve the problem.

This vehicle has left my family along side of a high twice. First time from lifter failure the second time from bearing failure. The bearing failure caused the vehicle to shut off and made for an unsafe pull off of a major highway. Both times this has happened with no warning till it happened. Lost of power with the check engine light coming on at the same time. No warning of any issues till it was to late a broke down. This could have been tragic to my family the second time around when complete shut down on an interstate highway why driving in heavy traffic. WITH NO WARNING boom shut off!! Every gm/chevy dealer I been too even say it’s been an issue and don’t understand why gm has not fixed the problem. These repairs alone cost us over 18000 out of pocket.
