2021 Toyota Venza Hybrid Transmission and drivetrain Problems

“While steadily accelerating on a freeway onramp, the vehicle suddenly accelerated, surged and gained speed rapidly without my control. I took action by braking and slowing the vehicle to a safe freeway speed. Thankfully no one in my vehicle was hurt and no other vehicle was near during the incident. There were no warning messages.

“While driving, vehicle suddenly lost all engine and electrical power and steering locked up. Fortunately I was stopped at a light at the time. Car restarted after I shifted into park and started in normal manner.”

Usually if you press the gas pedal past a point, it will kick in the gas engine with the electric drivetrain, but this did not occur. …”

The announcement screen started flashing a jumble of messages which only added to the hazard. First message was Your feet are on the brake and accelerator. My feet were on the floor. We were on cruise control. I put on the emergency flashers to warn traffic not to run into us. The highway ran through a water filled swamp with the shoulder too narrow to be safe.
