NHTSA complaint #11741489, 2026

“While driving, malfunction warning flashed on dash, followed by 48v malfunction warning, then engine coolant overheat warning. The car then went into limp mode and finally stopped completely. Luckily this occurred on a residential street and not on a high speed freeway - the car gave very little warning before drastically reduced speed and shutting down systems. A 48 volt battery problem should have a redundant system to prevent the engine from overheating and not shutting down the vehicle at speed. Very dangerous!”
