| Description of the problem | 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. |
