Tl*the driver owned a 2004 toyota sienna. While driving 60 MPH, the driver crashed into a semi-automatic truck. The driver and a passenger in the front seat were killed as a result of the crash. The contact stated that there were no indications that the brake was applied and that the vehicle may have accelerated forward. The current and failure mileages were not available.

Tl*the contact owns a 2004 toyota sienna. While driving at 65 MPH, the vehicle was involved in a crash but the air bags did not deploy. Three people were injured and a police report was filed. The vehicle was totaled. The current and failure mileages were approximately 118,000.
In early january 2011, the heater for the passenger car seat in my toyota sienna burned through the leather, through my 12 year old daughter's dress and superficially burned her leg. I believe the seat is defective as a fuse or other safety feature should have prevented such an injury/event.
Gas struts for rear lifting door gave out suddenly. Now door slams down unless physically held up. Happened day after we returned from skiing in lake tahoe for 3 days.
This vehicle has a traction control feature which helps keep it from skidding out of control in icy, wet, or otherwise unstable conditions. It can help an out of control vehicle get back into control by doing a variety of things, including braking. Previously this feature had only kicked on when I would slide on the snow during a low speed turn and would slide in the snow (which was good).
