NHTSA Complaint #10470300 — 2004 BMW X3

DRIVING IN NEIGHBORHOOD WITH STOP SIGNS AND CROSS STREETS. SPOUSE DRIVING. OTHER PASSENGER IN FRONT. ME IN REAR SEAT PASS SIDE. 10 MIN INTO TRIP. APPROACHING STOP SIGN, A FEW SECONDS AFTER BRAKE INITIALLY APPLIED, ENGINE BEGINS TO REV. HEAVY BRAKING STOPS VEHICLE, BUT ENGINE STILL REVVING. FROM BACK SEAT, I HAVE CLEAR VIEW OF DRIVER'S FEET AND CAN SEE THAT PROBLEM IS NOT MISAPPLICATION OF PEDALS. CAN ALSO SEE THAT HAND POSITION IS "10 & 2" AND NOT NEAR CRUISE CONTROL BUTTONS DRIVER TURNS OFF ENGINE TO STOP REVVING. WE CHECK FLOOR MATS TO SEE IF THIS WAS PROBLEM. THEY WERE NORMAL POSITION AND NOT NEAR ACCELERATOR PEDAL. WHEN ENGINE RESTARTED, PROBLEM DISAPPEARS. FRIGHTENING INCIDENT. THERE WAS A PEDESTRIAN IN CROSSWALK WHO WALKED IN FRONT OF VEHICLE WHILE THIS HAPPENED. *TR
