NHTSA Complaint #10056526 — 2003 FORD MUSTANG

MY 2003 FORD MUSTANG SVT COBRA COUPE HAS AN ENGINE STALLING ISSUE. THE ENGINE CAN STALL AFTER FOLLOWING THESE SEQUENCES IN ORDER WHILE OPERATING THE VEHICLE IN MOTION. FIRST I RELEASE MY RIGHT FOOT FULLY FROM THE GAS PEDAL, THEN PRESS IT ONTO THE BRAKE PEDAL, AND WHILE HOLDING ON THE BRAKE PEDAL I ALSO THEN WITH MY LEFT FOOT DEPRESS CLUTCH PEDAL DOWN FULLY, THE CAR MAY THEN STALL, BUT IT DOES NOT ALWAYS DO SO. STALLING CAN OCCUR WHEN THESE SEQUENCES IN ORDER ARE FOLLOWED WHILE OPERATING THE VEHICLE IN MOTION. IF DRIVING INTO AN INTERSECTION, THIS CAN POSE RISK DUE TO LOST VEHICLE POWER STEERING AND POWER BRAKE SYSTEMS IF THE ENGINE HAS STALLED. THE POWER BRAKES ON MY 2003 FORD MUSTANG SVT COBRA ARE BOOSTED BY THE POWER STEERING SYSTEM'S PUMP WHICH IS DRIVEN BY THE ROTATING ENGINE, THE BRAKES ON MY 2003 FORD MUSTANG SVT COBRA ARE NOT POWER ASSISTED BY THE ENGINE'S INTAKE VACUUM WHICH IS VERY COMMON WITH DOMESTIC VEHICLES. WITH A VACUUM POWER ASSIST DESIGN, POWER ASSIST CAN STILL BE AVAILABLE TO THE BRAKE PEDAL EVEN THOUGH THE ENGINE HAS JUST STALLED. ON THE OTHER HAND, WHEN THE ENGINE DRIVEN POWER STEERING PUMP STOPS TURNING WHEN THE ENGINE STOPS TURNING (IE HAS STALLED) ON MY 2003 FORD MUSTANG SVT COBRA, POWER ASSIST TO THE DRIVER TO PUSH ONTO THE BRAKE PEDAL IS LOST AND THEREFORE THE FORCE NEEDED TO PUSH DOWN ONTO THE BRAKE PEDAL IN ORDER TO SLOW THE CAR IS SIGNIFICANTLY MORE. THIS CAN BE A PROBLEM FOR THOSE WHO DO NOT HAVE THE ABILITY TO EXERT ENOUGH FORCE ONTO THE BRAKE PEDAL TO STOP THE CAR IN A TIMELY MANNER FOR THE CIRCUMSTANCES NEEDED IN AN INTERSECTION, SHOULD THE ENGINE STALL. ALSO, OF COURSE, THE POWER STEERING ASSIST TO THE DRIVER IN ORDER TO EASILY TURN THE STEERING WHEEL IS LOST. FORD SHOULD FIGURE OUT WHY THE ENGINE STALLS WHILE THE CAR'S IN MOTION DURING THESE CONDITIONS AND PUT FORWARD AN EFFORT TO FIX IT. THANK YOU. JOE.*AK
