problem #2

Jun 302015


  • 18,130 miles


I first noticed the incident today in a downtown area, speed of 35 mph. Upon removing my foot from the accelerator the RPM dropped to 1000, not lower, and the vehicle continued to move at the 35 mph. At every opportunity I was able to duplicate the event. As I entered our street I braked reducing speed. The vehicle RPM remained at 1000 and the speed was lower, but requiring braking to slow completly. I inspected the accelator pedal area, with my wife to verify that nothing was blocking the accelator. My wife and I took the vehicle on another test drive and was able to duplicate the event, crusing at 35 mph with no foot on the accelerator, RPM at 1000. The outside temp. Was approx. 102/104F. Weather clear and dry. The vehicle was used over the weekend for a round trip of approx. 700 miles. The vehicle is serviced on a regular basis, mileage upon parking was 18,135. I think this is potentially a serious safe issue.
