After making a complete stop vehicle rolled for about 4-5 feet causing a rearend collision. Dealer could not determine the cause.
The contact stated that the vehicle stalled without warning. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the issue. The failure mileage was 116,000. Updated 02/23/16 updated 05/04/18
Driving vehicle down freeway started smelling gasoline odor. Drove straight to nearest toyota dealer. To make a long story short, the seams of the fuel tank had split open.
The contact attempted to start the vehicle when the battery caught on fire at the positive post. He stated that he was able to extinguish the fire yet the vehicle would no longer start.
Vehicle was having a problem with the seat belts retracting. The seat belt did not go back into its original position after it was extended. Provide further details.
There was a strong fuel smell inside vehicle. Vehicle was inspected by dealer 5 times before fuel tank was replaced.
As highway speed is increased frontal/side wind off windshield caused at two different times for me to have to realign the car on the roadway due to this problem, also as the speed increases the inside of the car is noisy.
