Cruise Control problems of the 2010 Toyota Sienna

The contact owns a 2010 Toyota Sienna. When the cruise control was activated, it would deactivate independently. In addition, the bumper sensor detected objects that were not in front of the vehicle. The vehicle was taken to the dealer, but the failure was unable to be diagnosed. The vehicle was not repaired. The failure mileage was 100,000.

General complaint about rear side visibility during reversing. With baby car seats, on the driver side of the Mini van, the driver side rear windows are obstructed and the visibility is restricted considerably during back up. Asked Toyota if I can buy rear cameras but was told that it comes only factory installed. I consider this a serious anomaly. The Mini van occasionally runs without slowing down while the gas pedal is not used. It retains speed giving a false hope that it is on cruise control mode. Informed Toyota about the same and was told it is a feature.

My 2009 Toyota Sienna accelerated unexpectedly after the cruise control was set. This happened 2 different times while my wife was driving it. I was not in the car. My wife had to immediately press the brake pedal to release the auto cruise. After the brake was pressed the autocruise released the acceleration. Our car is not in the recall list I think. We never took our car for the recall repair at any time since we have had it.

I recently drove a rented 2010 Toyota Sienna van, from alamo rentals in san antonio texas. I found the cruise control system a bit quirky and a bit startling at first. Once the cruise control was set to 70 mile per hour, the system operated fine and maintained the set speed. However, once every 3 or 4 times the cruise control was disconnected using the brake pedal, then using the resume function of the cruise control, the vehicle would accelerate rapidly past 75 miles per hour. Once I disconnected the cruise control and reset the desired speed, the cruise control operated normally. This seemed to be a persistent but intermittent issue. Once I was aware of the potential for rapid acceleration and speed overshoot, I was able to anticipate and control the vehicle from running away. In light of all the issues concerning Toyota products, I though I would bring this to your attention. Driving conditions at the time of these incidents were dry concrete road, 7 passengers in the vehicle, highway speed of 70 miles per hour, outside temperatures were between 34 degrees f to 70 degrees f. Highway was straight and level.
