“While driving, the vehicle suddenly shut off without warning. The engine lost power and multiple dashboard warning lights illuminated. The vehicle then displayed a malfunction related to the transmission, with the park (“P”) indicator blinking, and the vehicle would not shift out of park. The failure appears to be related to an electrical or ignition system issue, possibly the ignition switch. This created a significant safety risk as the vehicle lost power while in motion, increasing the risk of a crash. Prior to the failure, the only warning observed was a check engine light. No other warning messages were present before the incident. The problem has been confirmed by an independent mechanic/contractor. The failed component is available for inspection upon request. This issue appears consistent with known ignition switch/electrical failures reported in similar vehicles”
