NHTSA Complaint #11713816 — 2022 TOYOTA TUNDRA

Vehicle experienced sudden engine shutdown at highway speed. While traveling at highway speed, the internal combustion engine shut off without warning. The hybrid system temporarily allowed propulsion, which enabled me to move the vehicle out of traffic and off the highway shoulder. After stopping, the vehicle would not restart for approximately 20 minutes. During this time, the vehicle was disabled and would not turn on. After the waiting period, the vehicle restarted and operated normally. No warning lights or messages were present prior to the shutdown. This event created a dangerous situation at highway speed and posed a significant safety risk to myself and my passengers. The vehicle is a 2022 Toyota Tundra Hybrid (i-FORCE MAX). Since the incident, the vehicle has been driven approximately 10,000 miles without recurrence, but the cause of the shutdown was never identified. I am concerned this event may be related to known engine defects or reliability issues reported for this model year.
