Dear. My name is [XXX] . Phone # [XXX] . My email: [XXX] On [XXX] my Tahoe suddenly shut off while I was driving over 70 mph on the highway. It was towed to the South pointe chevrolet dealership in tulsa. I was told a fuse had failed and paid nearly $400. On April 17, 2025 they returned my Tahoe and said it fixed. [XXX] When i tried to start engine, then it acted like something almost can't start, then i text dealership and told them situation. On [XXX], the same failure occurred again — again at highway speed — nearly causing an accident with an 18-wheeler. The Tahoe was towed a second time. 2 times i was able to re-start engine drive until i stop then can't start it agian. Both time i smell something burned when i tried to re-start it. On April 21, I texted the service manager about GM TSB N252494000, which describes propulsion loss involving the L87 engine — the same engine in my Tahoe. Two days later, I was sent an invoice for $865.30 for a starter replacement. I was told the repair would not be covered under warranty — despite the vehicle still being under 60,000 miles at the time and the defect appearing to fall under a known GM issue. This is a recurring, life-threatening failure that GM and its dealer have not fixed. The vehicle is still under warranty, yet GM is refusing to cover the repairs.

Driving my Tahoe (67,000 miles) down the highway and everything is perfectly fine, suddenly all of the check engine lights began to flash. I wasn’t sure if it was an electrical glitch or not until the engine started knocking loudly. I was on a bridge in traffic and had no where to safely pull over. I had to drive a few miles further just to get to safety at which point the knocking became extremely loud and the entire car began shaking. I had the vehicle towed to the dealership where they informed me the lifters had gone out as well as the cam shaft. Apparently this is a very common occurrence among owners of this vehicle/similar vehicle. I am so grateful this is the one time my two small babies were not with me. It was a very scary situation and I was hours from home. This came completely out of no where without warning. Of course this happened 7,000 miles out of warranty. So now after paying over $70,000 for a vehicle that is barely 3 years old and only driven in town for the majority of that, I was stranded and now going to be out $10,000 to repair.

While driving from Boise, Idaho to Jackson, Wyoming our 2022 Tahoe 6.2L with 70K miles shut down at 85MPH on Highway 84 outside of Pocatello. Luckily, my wife was able to coast off the exit. We had the Tahoe towed to the Dealer and advised it would be 4 months for a new engine as our order was number 4,000 in line for an engine. Luckily, all of a sudden engines arrived from the supplier and was replaced in 3-4 weeks. Tariffs must have sped up the process. Downside, I paid 50% as we were out of warranty and GM would not cover the entire cost. Now I see the recall and would expect to be re-imbursed. We will see.

At 22,000 miles on the Interstate highway, vehicle suddenly lost all power, no throttle, went into neutral and we were lucky to be able pull it off to the shoulder without an accident. It had stalled and after multiple tries we were able to restart it. Then the check engine light came on and we drove it directly to dealer. There was a code for camshaft sensor and we were told all lifters needed to be replaced. Upon doing so, they found metal pieces in the engine and said entire engine needed to be replaced. The engine was on back order for up to several months. We waited a month then decided to trade due to loss of vehicle use. Dealer was very helpful during repair but no assistance from GM for a known issue on the 6.2L that could have had a negative outcome on the highway. This was not only a safety issue but a very expensive situation to trade out of for an almost new car.

Purchased brand new. Had for awhile and the veh shook. Took it in and the replaced with all brand new lifters. Still not correct than replaced with all new fuel injectors. Now when I take it in for the last several months it’s 1.5 to 2 quarts low on oil. Told that GM standard says 1.5 quarts low between oil changes is normal!!! I’m currently on an oil consumption test at each 1,000 miles snd I’m at 2 qrts with 1,500 til my next oil change. The volume on the radio goes up and the computer is stuck and you cannot turn the radio off or use the computer screen at all. You have to turn off the vehicle and start it again in order for the buttons to work.
