2024 Buick Envista electrical system problems

“My 2024 Buick Envista experienced catastrophic engine failure at 42,000 miles, requiring an engine replacement on Feb 11, 2026, after a rod failed and caused severe internal damage. Around 50,000 miles, the vehicle began stalling or losing acceleration when coming to a stop, with the check engine light. I have also experienced “Service Power Steering” and “Service Theft Deterrent” warnings and an incident involving the steering wheel locking. Restarting the vehicle several times the vehicle resets it self and works These problems create serious safety risks, including losing acceleration in traffic, being unable to maneuver safely, and potentially losing steering control. The vehicle has been taken to a dealership multiple times, but the intermittent issues have not been reproduced or conclusively diagnosed. The dealership initially mentioned battery corrosion and later a weak battery. General Motors has been notified of the situation.”
