NHTSA Complaint #10433560 — 2007 FORD MUSTANG

I PULLED OFF THE FREEWAY INTO A REST STOP AREA. MY FOOT WAS ON THE BRAKE, AND ONLY ON THE BRAKE. I STOPPED IN A PARKING SPACE AND MOVED THE AUTOMATIC TRANSMISSION LEVER FROM DRIVE TO PARK. THE RPM INSTANTLY INCREASED FROM APPROXIMATELY 600 RPM IN DRIVE TO APPROXIMATELY 6000 RPM IN PARK. I TOOK MY FOOT OFF THE BRAKE PEDAL AND GAVE THE GAS PEDAL A QUICK TAP. THE RPM RETURNED TO NORMAL, ABOUT 750 RPM IN PARK. THE DEALERSHIP INSPECTED THE CAR, BUT COULD NOT FIND ANYTHING WRONG. THEY CONTACTED FORD, WHO MAINTAINED THE INCIDENT COULD NOT HAVE HAPPENED THE WAY I DESCRIBED IT. THEY FURTHER TOLD THE DEALERSHIP NOT TO PERFORM ANY REPAIRS UNLESS A SIMILAR INCIDENT RECURRED. THE DEALERSHIP THINKS THE PROBLEM IS WITH THE FLY BY WIRE, THROTTLE BODY AND/OR CONTROL OF THE FLOW SYSTEM. *TR THE CONSUMER HAD CONCERNS ABOUT BRAKE FLUID. THE OWNER'S MANUAL STATED TO USE DOT 3 BRAKE FLUID. HOWEVER, THE DEALER USED DOT 4 BRAKE FLUID. UPDATED 11/09/15. *JB
