2017 Toyota Sequoia Other Problems

Your vehicle suddenly accelerated while parked with the engine running and three children inside, causing it to crash through trees and fences before stopping in the woods. When you reached the vehicle, you found the gear shift had moved out of Park to a position between Park and Drive, and the engine was still revving at high speed. You also reported two earlier incidents where the vehicle experienced unexplained power loss and surge issues, followed by sudden deceleration and reacceleration on cruise control, which Toyota was unable to diagnose or repair. The repair will likely require a full diagnostic of the transmission shifter mechanism, electronic throttle control system, and cruise control electronics to identify why the vehicle is shifting out of Park and experiencing unintended acceleration.

Your sunroof spontaneously shattered while you were driving. This is a sudden failure with no known cause at the time of the incident. The repair will likely require replacement of the entire sunroof glass panel and associated hardware.
