2008 Toyota Sienna Owner Comments

While passenger side visor is down smoke starts pouring out from under the head liner. When the visor is placed back in the closed position smoke clears out and stops. Per the mechanic, a short in the electrical system has resulted in a melted electrical board and the entire head liner and electrical board needs to be replaced. The visor can not be used or the short may start a fire inside the vehicle. The vehicle was in motion when this occurred. Van filled with smoke quickly. Had to pull over and open doors to clear the smoke.

When driving on a back road under dry conditions, the traction control light will illuminate as well as an auditory warning. The brakes are also applied. This has happened several times now. Many others have had this problem and have been unable to resolve it. This could be dangerous if vehicles are following behind as the brakes are applied forcefully. This usually happens between 30-40 mph on back roads, only on curves. However, the vehicle is going an appropriate speed for the corner, and there is no reason for this system to engage. The vsc warning light had been on, but had turned off as if the problem had fixed itself. The vsc light turned on on December 24th 2015 and turned off on December 26th, 2015.

The contact owns a 2008 Toyota Sienna. While driving 45 to 50 mph onto a highway, the vsc light illuminated on the instrument panel, an alarm activated, and the anti lock brakes engaged. The vehicle was taken to the dealer for diagnostic testing on four separate occasions. The dealer could not duplicate the failure. The vehicle was not repaired. The failure mileage was 88,000. The VIN was not available.

Car pauses at slow speeds. Car jerks first, then check engine light comes on, trac off light comes on. Vsv light comes on. Code diagnosed as dtc PO717. Toyota dealer does not know how to fix it. Suggests trial and error. Vehicle hesitating is dangerous.

Unintended acceleration incident. Car was driven 200 miles the previous night and garaged. The next morning, car was started, backed out of driveway, and driven 15 mph for 1/4 mile until on main road. After traveling 0.4 miles on main road I slowed to a red light. The engine started racing (but not red-lining). I am absolutely sure my foot was not on the accelerator pedal. I shifted into neutral, which removed the forward pressure, and after a second or two, the rpms drifted back into the normal range. This is the most recent occurrence. Other instances have been less severe and have all occurred while braking the vehicle.
