Lifter failure resulting in a bent pushrod, camshaft, and piston damage. The engine was very dirty like the oil changes were neglected. I always changed the oil in 5,000 mile increments or less depending on driving conditions. The owners manual and oil filler specifies Mobil 1 5W30 oil. When I was working I always had the shop next door change the oil with Mobil 1. After I retired in 2019, I had the nearby GM dealer change the oil. I was unaware that they were substituting DEXOS oil which is not what the owners manual or fill cap specifies for this vehicle. This resulted in premature engine failure. With DEXOS you could be getting oil that is inferior to Mobil 1 full synthetic. See [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Replaced oil pressure sensor. Replaced spark plugs. Wires. And coils. Will not clear misfire and won’t go out of limp mode. $7500 fix. This is ridiculous. I have heard of 15 others with the same issue.

Low oil pressure causing engine failure, suspension issues constantly, limp mode won’t go off

 For approx. the past 6 months, the radio has been cutting out several times during my daily commute. On occasion, a message would appear saying Stabilitrack is off. Saturday, it cut out and stayed off for more than 30 minutes and did it several more times. Everytime the radio cuts out, the door locks started locking and unlocking on their own, the air conditioning, cooled front seats, and defrost turns on and the seats the airbag off light came on, and a warning message saying service stability system came on, plus the engine was revving without power and I was worried I was going to lose all electrical and control, so I pulled off the We have ran several diagnostic but found no error code messages and nothing wrong with the vehicle. When I was talking to them, the system was acting normally. I have taken the car to the...
