The engine of this car has been under recall for multiple issues during the time we have owned it. The most recent issue that was experienced was total engine failure and electrical malfunction while driving on a busy street near train tracks. The vehicle was making a loud banging sound moments before this occurred. I wasn't even given time to get to a safe spot to investigate the issue. When it shut down, a quick message flashed across the dash board--stating ability to shift had been lost (or something to that effect)--the vehicle then flipped into neutral and immediately lost power. My safety was put at great risk due to the fact that the entire vehicle shut down moments after I crossed over a very busy railway track. The vehicle had to be towed to a nearby Chevrolet dealership where it has been confirmed there was total engine failure as well as blown main electrical fuse.

Wareing Sheridan Chevrolet in [XXX] replaced the engine, and the vehicle was out of service approximately 12 to 14 days.

There were no warning indicators of any kind until I suddenly lost power. Only at the moment power was lost did the check engine light come on and a low oil pressure warning appear. I was barely able to get the vehicle off the interstate before it died. I had my family in the vehicle, and losing power on the interstate with no warning created a serious risk of a crash. The vehicle had to be towed to Denny Menholt Chevrolet in Billings, MT. On June 13, 2026, the dealer con...

The vehicle was shaking and shuddering when trying to maintain highway speeds. Would have to slow down to maintain safety. The dealership advised the transmission needs replaced however we are seeing this is a widespread problem that GM has refused to admit fault for.
