My 2022 Chevrolet Tahoe diesel unexpectedly lost power while driving. I was stopped, made a right turn, and accelerated to approximately 34–40 mph on a two-way street when the vehicle suddenly shook, shifted into neutral, and the engine shut off without warning. There were no warning lights, dashboard messages, or prior symptoms before the failure. I was driving with two young children secured in car seats at the time. This created a serious safety risk because the vehicle became disabled in the roadway, and I had limited control while traffic was present. The vehicle has not yet been diagnosed, and the exact failed component/system is unknown. The vehicle is available for inspection upon request. The incident has been reported to a dealer or service center, but the problem has not yet been confirmed or reproduced at this time.

Vehicle continues to experience flashing air bag light and service self-restraint system warning. Brought in twice in 2025 for self-restraint system but dealer refuses to cover under warranty. On December 18, 2025, experienced complete power and electrical failure while in transit on a turning lane. The vehicle was unable to start, or open any windows, and the transmission would not shift back into park or neutral while obstructing traffic near an active railroad. Vehicle battery was replaced and was able to safely put vehicle into gear. Vehicle battery replacement allowed for normal driving; however, from that date on the transmission started shifting harder and jerkier. On December 31, 2025, vehicle was being driven on the freeway to then experience difficult shifting and reduced power. Subsequently, the drive indicator began flashing red and a service transmission indication appeared. There has been at least three instances, since vehicle purchased, where sudden loss of power and control of the vehicle in motion has occured.

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.

It was found that the engine had blown and am still waiting for a replacement.

While driving on the highway the engine started to makes noise and shut down in seconds without warning- we glided down an off-ramp narrowly avoiding oncoming traffic and was towed away on the ramp - the engine only has 68,000 miles and it well maintained. It’s my understanding that the federal safety agency is investigating problems with the 6.2 L engines on 2022 Tahoes that have sudden lost of power please add my name to the investigation- GM has refused to help I’m hoping that a recall which is warranted will help with the $11,869 cost to replace the engine.

Vehicle suddenly lost power at 70mph in heavy traffic. This was after a very brief flash of the electrical system off and then back on. Vehicle was safely pulled to the side of the road (luckily). The electrical system kept demanding to “push start” and then would shut off and then immediately come back on, but without the engine starting. The vehicle would not completely turn off, or turn back on from that point forward, killing the battery in the process. We called Onstar, who had it towed to Bill Estes Chevrolet in Carmel Indiana. Mark in the service department then informed us that the engine was completely seized up and would require an engine replacement.

Vehicle reduced power and displayed many errors on the dashboard, including reduced function of forward collision avoidance, reduced acceleration, ESC SES TC. A vibration/rumble was observed (unsure if it was steering assist or propulsion surging), as well as increased engine speed without vehicle acceleration and no engine speed increase while pressing the accelerator. Turns seemed to make the symptoms worse and cycling power on the truck would temporarily clear the faults. Root cause was determined to be TSB 21-NA-149 Cause 3 and diagnosis and repairs took more than a week.

Purchased car on April 7, 2022 with 10 miles on it. Drove home, parked car in driveway and a few days later went to start car and no power. Car had 22 miles. Start button was stuck on on but no power and engine was off. I could not get the start button to turn off. Car towed to dealer. Dealer checked car and couldn’t find anything wrong they called GM support and checked for known issues with other 2022 Tahoes. Nothing found. Software updated. Battery has full charge. Car released. I drove car home, parked in driveway and after a few days went to start car - same issue no power. Car has 44 miles. Start button stuck in on but no power, engine off, could not turn off start button. Car towed to dealer. Dealer kept car for a week. Dealer contacted GM support. Found that battery was draining but could not find what was causing drain. Dealer replaced battery. Car released. I drove car home and so far now at 200 miles the car seems ok. I am reporting this because what if I had lost power while driving on the highway. Plus I have heard of several 2002 Tahoe owners that this is occurring. The dealer has been great. I blame this on GM for releasing a bad car.

While driving, I heard a ticking noise, that sounded like rocks being thrown in the fender well. The more I drove, the sound and frequency increased. Then, I started to lose power, like it was taking longer to shift. My safety and others were at risk because continuing to drive with lifter issues could’ve caused engine failure, which could’ve caused an accident. The problem was confirmed at a dealership. I don’t know if anyone else inspected it. No lights appeared until after I had it towed to the dealership. They said the warning lights came on for them.
