IN DECEMBER OF 2002 I PURCHASED A 2003 SVT COBRA MUSTANG FROM SATCHER FORD. THIS CAR HAD A NUMBER OF PROBLEMS WHICH CAUSED FORD TO REPLACE THE ENGINE, RE-FLASH THE COMPUTER, REPLACE CLUTCH. THIS CAR HAD A STALLING PROBLEM THAT LEFT ME AFRAID TO DRIVE IT. WHEN YOU WOULD DEPRESS THE CLUTCH, THE CAR WOULD SOMETIMES STALL. THIS WOULD CAUSE THE LOSS OF BRAKES AND STEERING AND NEARLY CAUSED AN ACCIDENT. FORD FINALLY AGREED TO BUY BACK THE CAR AND GET ME ANOTHER CAR, BUT I AM HAVING THE SAME STALLING PROBLEM WITH THAT 2003 COBRA AS WELL. SATCHER…

2003 FORD MUSTANG COBRA... VEHICLE WILL STALL WITHOUT WARNING WHEN CLUTCH IS DEPRESSED. OFTEN THIS HAPPENS WHEN COMING TO A STOP AND SHIFTING GEARS. WHEN THIS HAPPENS THE BRAKES AND STEERING IMMEDIATELY STOP WORKING. WHEN STOPPING ON AN INCLINE THIS CAN CAUSE A SITUATION WHERE YOU EITHER ROLL INTO THE VEHICLE IN FRONT OF YOU OR OUT INTO THE MIDDLE OF AN INTERSECTION. I HAVE HAD NO ACCIDENTS YET BECAUSE OF THIS BUT I HAVE HAD 1 CLOSE CALL. *JB

TL*THE CONTACT OWNS A 2003 FORD MUSTANG. THE CONTACT STATED THAT THE WIRING THAT LEADS TO THE BRAKE LIGHT SWITCH CONSTANTLY FAILS.

NEW TERMINAL ENDS WERE PLACED ON THE SWITCH; HOWEVER, THE WIRING CONTINUES TO FAIL. THE REPAIR USUALLY LASTS SIX MONTHS. THE VEHICLE HAS NOT BEEN TAKEN TO THE DEAL…
