Description of the problem | The mazda cx-9 uncommanded engine acceleration reported herein did not result in any damage primarily because it commenced several seconds after i began light braking while approaching a red traffic light. My immediate response was to increase brake pressure; there was no need for me to move my leg other than pressing harder with my foot. My foot had been off the accelerator for many seconds while allowing the car to slowly decelerate while coasting toward traffic stopped at a red light. Within two seconds of commencement of uncommanded engine acceleration and with the car fully stopped, i shifted the transmission into neutral. The engine immediately generated the noise of very high rpm. Although the dashboard includes a tachometer, i did not immediately think to look at it; instead, i turned the ignition off. A few seconds later, i shifted the transmission into park and restarted the car which operated normally thereafter. My foot did not move off the brake pedal during any of the preceding sequence. Only the nhtsa and possibly the manufacturer would know if this is a one in a billion-hours or a more common occurrence. I am willing to answer any questions the nhtsa or the manufacturer might have. I graduated from mit, worked over 29 years for the leading usa commercial aircraft manufacturer and am currently retired. |
