Complaint Timeline
Chronological view of owner reports
On April 2, 2025, while driving on Interstate 25, my 2021 Audi Q8 Premium Plus experienced a catastrophic engine and electrical failure. This included the generator system failing, which resulted in a complete loss of power, disabling all active safety systems (including electronic stability control, braking assist, and lane monitoring), as well as basic driving capabilities such as acceleration and steering responsiveness. The incident occurred without prior warning or diagnostic alerts, and the vehicle became immobile on the highway. The situation posed a serious safety hazard to both myself and surrounding drivers. The vehicle had an unresolved generator recall, which Audi later confirmed and completed after the incident. This event raises significant concerns regarding system reliability and pre-failure alert mechanisms in the Q8 platform.
