Electrical fire inside parked van occurred overnight and burned driver and passenger front seats, dash, and all air vents and all plastic component located near all vents. Van was parked on street in front of my house.
The contact owns a 2004 Toyota Sienna. The contact stated that the air bag warning indicator flashes intermittently on the instrument panel. The vehicle was taken to the dealer approximately three times and they stated that the wiring in the seat back needed to be replaced. The current mileage was 52,622 and failure mileage was 47,000.
My children were trying to get to the third row seat and pulled on the latch of the seat on the second row and the seat rapidly snapped down and out crushing my little one. Since that incident my children were very careful about using the handle to bring the seat down. I have had other people ride in my car that do not know how fast and dangerous these seats snap down and out that have been hit by the seats on my occasions. We call it the "jaws of death" but this is not a laughing matter. I did write to Toyota about this but never even received a response. The other problem we've had has been with the sliding doors. They keep breaking and not closing properly.
