2022 Chevrolet Tahoe Engine

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 NHTSA 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.

ENGINE QUIT RUNNING UNEXPECTEDLY, WITHOUT WARNING, AS WE WERE DRIVING DOWN THE FREEWAY ABOUT 30 MINUTES FROM OUR HOME. FORTUNATELY, WE WERE ABLE TO GET OFF TO THE SIDE OF THE ROAD BUT FACED DIFFICULTY IN GETTING THE VEHICLE ON THE TOW TRUCK. NO POWER SO ELECTRONIC PARKING BRAKE WOULD NOT DISENGAGE FOR MORE THAN A FEW SECONDS. PLUS THE REAR WHEELS WOULD NOT TURN AT ALL. WE DID GET FINALLY GET THE VEHICLE TOWED TO A NEARBY MECHANIC WHO INFORMED US THAT THE ENGINE HAD SIEZED AND WOULD HAVE TO BE COMPLETELY REPLACED WITH A BRAND NEW ENGINE. SUSPECTED MAIN BEARING FAILURE. I HAVE READ THAT YOU ARE INVESTIGATING PROBLEMS WITH THIS ENGINE, GM L87 6.2L V8.

[XXX]. We dropped our vehicle off at Chevrolet on old Seward after our engine seized while on the highway. We had to exit the highway with our five children inside. We had it towed to Chevrolet for them to fix in which the car was finally ready for pick up [XXX]. Not to mention when GM sent the tow truck, it couldn’t even tow our vehicle. They had to order another tow truck because the manual override for the parking break wouldn’t release so I had to sit in the feeezing cold WITH MY KIDS for over an hour. #3 MAIN CAP SEIZED CAUSING ENGINE TO NOT TURN OVER AND ROD SEIZED AS WELL. The issue required a complete engine replacement. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving under normal conditions, the 6.2L engine in our 2022 Chevy Tahoe seized and stopped running. We were lucky that it was early in the morning and without a lot of traffic and were able to coast the vehicle safely off of the road. Upon inspection from the dealership, they indicated that the engine experienced catastrophic failure. The dealership replaced the engine, Battery, Starter, Fuse box, and steering gear. We were lucky as the failure occurred just prior to us getting onto the interstate. Prior to the failure, there were no warning lights or issues with the vehicle. It was a sudden and catastrophic failure.

Exhaust system failure. Was told by manufacturer vehicle dealer service center that cause of the failure was not from normal use or misuse but due to manufacturing and weak metal/poor materials. No warning lights or messages ever appeared on vehicle information system. First report of exhaust smell in vehicle cabin on 4/9/24 at 38,874 miles. Vehicle dealer service center tested for leaks and found no leak. Second report of exhaust smell in vehicle cabin on 8/6/24 at 48,106 miles.

Car went to shop on 11/5/24 at 55,077 miles. Two exhaust leaks detected. From dealer: "Smoke tested exhaust system and checked for leaks, found a hole in the exhuast pipe right before the muffler and is likely the source of the smell." Additionally from dealer, after first repair: "After exhaust repair the vehicle was started and heard and audible exhaust leak on the drivers side. After further inspection found the drivers side exhaust manifold is leaking as well." I have been driving this vehicle for at least seven months with exhaust leaks and with exhaust coming into the cabin of my vehicle exposing myself and passengers to carbon monoxide. Reported twice to dealer and they reported no issues.

Check engine light came on due to a P1098 and I received a reduced acceleration advisory. This greatly diminished the performance of the vehicle and made it a hazard to continue on the highway

Our family of 5 (including 2 children and an infant) was driving 70 mph westbound on Interstate 40 east of Knoxville, TN when our 2022 Tahoe RST engine seized. For a few seconds, we had no steering, braking or acceleration and the dashboard began flashing. After a few seconds, the car shifted itself into the neural gear and we were able to brake on the shoulder of a busy highway. We were unable to restart the car. We called the police as well as AAA. The police came and sat behind us to deter oncoming cars to changes lanes. AAA came and towed our car to Reeder Chevrolet dealership in Knoxville, TN. There, it was determined that our engine had seized and needs to be replaced under warranty However, there is a backorder on the engine, and we are now driving a rental car. There are several other Tahoes in their service department with similar circumstances in need of a 6.2L ecotech V8 engine. There was no warning at all that the car had problems. Up until this point, there were no issues. I believe there is a widespread problem with these particular engines and this should be addressed on a national level. Our lives were at risk.

Driving on highway and car started making a loud noise and it completely stopped, had to tow to the dealer.

Will coming to a stop the vehicle would just stall. Didn’t notice the dash saying to restart and as let off of break the truck started to roll backwards almost hit car behind me. Did this about 7 more times. Made appointment with dealership and they told me there was no problem found.

vehicle has 5500 miles on it, bought new in July 2022, driving on the interstate at night, vehicle shut down without warning, no warning light or check engine lights came on. Had to have it towed to the dealership and they said it had complete engine failure and have to replace the engine. Barley got it off the interstate, lucky no one was hurt.

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.
