NHTSA Complaint #10331665 — 2007 CADILLAC CTS

I PURCHASED A USED 2007 CADILLAC CTS IN NOVEMBER 2009. FROM THAT TIME, IT ALWAYS HESITATES WITH THE FIRST FORWARD ACCELERATION OF THE MORNING, AND THEN HAS A FORCEFUL ACCELERATION AS IT OVERCOMES THE HESITATION/ALMOST STALLING, AND THEN DRIVES NORMALLY. AS THIS WAS A NEW CAR FOR ME, I THOUGHT THAT MAYBE THE CAR NEEDED TO WARM UP DUE TO THE COLD WEATHER OVER WINTER. ONCE THE TEMPERATURES INCREASED, THE CAR CONTINUED TO EXPERIENCE THE PROBLEM - DAILY. THE CAR IS AT THE DEALER AGAIN - 5TH VISIT SINCE MARCH 2010. THE FIRST VISIT THEY FOUND NOTHING, THE SECOND VISIT FOUND A WORN TIMING BELT, THIRD VISIT FOUND NOTHING, FOURTH VISIT TOOK 5 DAYS AND FOUND CONNECTIVITY ERRORS WITH THE DRIVE-WIRE SYSTEM. THERE WAS AN ERRATIC SIGNAL FROM TAC MODULE; REPLACED TERMINALS CIRCUIT # 581 & #582 (THROTTLE ACTUATOR). THE REPAIRS DID NOT FIX THE ISSUE AND I TOOK THE CAR BACK AFTER 3 DAYS FOR THE 5TH VISIT. THE DEALER HAS INDICATED THAT THEY HAVE REPLICATED THE PROBLEM, BUT DO NOT KNOW HOW TO SOLVE IT. THIS COMPLAINT HAS BEEN ESCALATED UP TO THE DISTRICT-LEVEL SUPPORT AND I AM NOW WAITING FOR GM TO SEND AN ENGINEER TO THE DEALERSHIP TO TRY TO FIGURE OUT HOW TO SOLVE THE PROBLEM. IT IS FRIGHTENING TO DRIVE A CAR THAT REPEATEDLY WANTS TO STALL AND THEN OVER-ACCELERATES TO OVERCOME THE PROBLEM CAUSING THE HESITATION. IT IS ALSO FRIGHTENING THAT IT IS TAKING 5 VISITS FOR THE DEALER TO RECOGNIZE THE SERIOUS NATURE OF THIS PROBLEM, WITH NO SOLUTION IN SIGHT. IT IS UNSAFE TO DRIVE A CAR THAT RANDOMLY TRIES TO STALL, AND THEN OVERCOMPENSATES BY A STRONG/FORCEFUL ACCELERATION. *TR
