The car was off, the key was not in the ignition. My two year old daughter was in the front of the car. She touched the shifter and it went between park and reverse; the car started rolling down our driveway. She did not press the brake (she is unable to) but the car went into reverse. The van hit a tree. We checked and the car was in between park and reverse. So, somehow, the car reversed even though it was in park, turned off, and the brake was not touched.

The contact owns a 1999 Toyota Sienna. The contact stated that after shifting into park, the gearing shifter arm fractured. The vehicle was towed to an independent mechanic for repair, who stated that the entire gear shift module would need to be replaced. The manufacturer was made aware of the failure. The failure mileage was 90,000.

All the above data is an estimate becuase we are waiting for copies of all maintenance and repair records from Toyota - - but we have had multiple problems with this vehicle including screeching brakes, left veer when driving, bad transmission (replaced twice),smog check failure due to oxygen sensor and/or engine problems, clunking noises in engine, a shuddering of vehicle when driving or braking. The car has been at dealers for as long as 3 weeks; dealer admits not knowing what is wrong. Failed

Speedometer not working at startup. After some driving, the needle begins to register. Dealerships says a "sticky substance" (??) caused inoperative needle.
