This complaint is an addendum to a complaint I filed last week regarding the suspension of my same vehicle. 1. Battery: battery died several times without warning and the cause was never found. Took 4 trips to the dealer to get a new battery placed. Dealer blamed various -??modules-?? each time. I believe that electrical system is faulty because the windshield wiper sprayer also stopped working, and the heads up display flickered at times. Issue 2: -??low engine oil pressure warning. Turn vehicle off immediately-?? warning at 17,800 miles while driving on the highway. Had to immediately pull over and per GMC, the vehicle was not able to be driven and had to be towed to the dealership, leaving me stranded at night in a vehicle that I couldn-??t turn on while I waited to be picked up.

The lifters failed about two months from buying it from the dealership. The vehicle was new and only had 13 miles when it was bought. The vehicle had about 600 miles when the lifters failed. As he vehicle was being driving on the highway it started making a clicking noise and the engine would pull and lost power. The vehicle was taken to the dealership and was in service for about 3 weeks for repairs. No one other than the dealership has inspected the vehicle. There was no warning lamps, messages or symptoms prior to the failure.

While stopped at a stop sign the vehicles start/stop activated and turned off the engine. When I released the break to hit the gas the engine would not turn back on. I was stuck in the middle of the road and unable to restart my vehicle. After several minutes of trying to turn the vehicle off/on it started back up. The second incident happened when using the remote start. Once I entered the vehicle and put my foot on the brake and hit the start button the engine completely died. Radio and heat stayed on but the engine wouldn't turn over. After letting it be for a half hour everything was still on inside the vehicle but the engine still wouldn't turn over. I disconnected the battery and reconnect it. Once that was done the vehicle started back up. Vehicle was brought to the dealership, but was told there is no fix and to not use the automatic start or auto start/stop on the vehicle

On September 9th at approximately 5:00 pm, my wife and I left Augusta and headed to Atlanta to attend an event. While driving highway speeds of about 70-80mph, the vehicle began to decelerate rapidly and then shifted itself into neutral gear. Unable to shift back into drive, I was forced to maneuver my slowing vehicle onto the shoulder of the highway, placing myself and my wife in danger of colliding with the other vehicles who were still travelling at highway speeds. After pulling over onto the shoulder, I was able to shift the vehicle into park and turn it completely off. After a few minutes, I turned the vehicle back on and integrated back into traffic. Approximately 20 minutes later, the vehicle began to have trouble accelerating and I was unable to exceed 65mph on a highway where the speed limit was 70mph, and the other vehicles were exceeding that. My wife and I were sitting ducks in Atlanta traffic. I once again planned to pull the vehicle over when it suddenly made a loud noise and began to vibrate violently. From the far left lane, I found myself fighting with a vehicle that refused to accelerate and was now becoming uncontrollable. I managed to take the next exit, and parked the vehicle. After turning off the vehicle, I waited a few moments and tried to start it again. The vehicle did start, but continued to vibrate aggressively, as well as make loud clunking and squeaking sounds from under the hood. There was also a smell of something burning. For our safety, my wife and I exited the vehicle, as it had been rendered completely inoperable. I was forced to have the vehicle towed. The vehicle is currently at John Miles Chevrolet Buick GMC in Conyers, GA. (678)374-4695. The dealer has not confirmed the problem. No inspection has been done to date. When to vehicle shifted to neutral I believe the only warning light said "Conditions not correct for shifting". It only appeared when the vehicle shifted into neutral.

July 5, 2022. Engine Lifter Failure. While driving my new 2022 Yukon Denali (with only 14,400 miles on it), I made a right hand turn into a parking lot. The engine just shut off. No warning lights ever came on. The only thing I had noticed was some unknown noise when I started up the truck and getting underway. The sound promptly went away. I attempted to restart the engine but it would not even turn over. My vehicle was blocking the driveway to the parking lot, creating a traffic hazard on a major street. I had the vehicle towed to a GM dealer who determined the next day that engine had failed due to a known lifter problem. The head mechanic was able to get the truck restarted and the same issue replicated itself. The mechanic received approval to replace the entire engine assembly, but it is on back order. There is no ETA to when the parts will be available. I am fortunate that the vehicle did not shut down in a lane of traffic, on the freeway, or out in the desert or mountains. From my research, this issue with the engine lifters in the 6.2 liter engine has been known by GM for well over 10 years. The engine needs to be recalled and the lifter issue corrected.
