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.
VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE04/28/2026
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.
