While driving down the highway, the vehicle suddenly experienced multiple issues. The headlights went out, the vehicle would not continue to accelerate, and all interior lights shut off. The vehicle then shifted into neutral and stalled. There were no warning signs or indicators before this happened. Our safety was at risk as we barely managed to pull the vehicle over to the shoulder, with no working emergency lights. The highway had no street lights, and we were constantly worried about being hit by other cars since our vehicle was nearly invisible without the emergency lights. The malfunction left us stranded more than two hours from home. We had to have the vehicle towed to a Chevrolet dealership for inspection, which was also over two hours away. Prior to the failure, there were no warning lamps, messages, or other symptoms-?"everything happened suddenly without any notice.

- Reno, NV, USA

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. Since our vehicle has 75000 miles and is out of warranty we are facing repair charges of up to $15000 to $20000. We could use a little justice. Thank you.

Tow truck was called to transport us to the local Chevy dealer in Hammond LA - Ross Downing Chevrolet. Since it was a Saturday, we had to wait for the dealership to reopen on Monday. On Monday, I was called and told that there was indeed complete engine failure, and later in the day it was determined that it was due to a rod bearing issue.

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.
