2005 Volkswagen Jetta Cruise Control Problems

TL*THE CONTACT LEASED A 2005 VOLKSWAGEN JETTA. THE VEHICLE IS A DRIVE BY WIRE VEHICLE AND THERE IS NO MECHANICAL CONNECTION BETWEEN THE ACCELERATOR AND THE ENGINE. THE DRIVE BY WIRE IS PART OF THE CRUISE CONTROL. THE CONTACT IS A TWO FOOT DRIVER AND THE VEHICLE WAS NOT MODIFIED. WHILE ACCELERATING, THE VEHICLE FAILS TO MOVE FORWARD. THE DEALER STATED THAT THE FAILURE OCCURRED DUE TO AN INTENTIONAL COMPUTER PROGRAM, WHICH PREVENTS SIMULTANEOUS BRAKING AND ACCELERATING IN ORDER TO PREVENT STRAIN TO THE DRIVE TRAIN. THE DEALER ALSO STATED THAT THERE WAS NO REPAIR AVAILABLE TO PREVENT THIS FROM OCCURRING. ON OCCASION, WHILE ATTEMPTING TO MAKE A LEFT TURN AGAINST TRAFFIC OR TRYING TO MERGE, THE VEHICLE FAILS TO MOVE FORWARD. WHEN THE VEHICLE DOES MOVE FORWARD, IT ACCELERATES AT HIGH SPEEDS, APPROXIMATELY 50 MPH AND CAN BE DIFFICULT TO CONTROL. THERE HAVE BEEN 15 OR MORE NEAR CRASHES. THE MANUFACTURER INFORMED THE CONTACT THAT THE COMPUTER INTERLOCK BETWEEN THE ACCELERATOR AND BRAKE PEDALS WERE FEDERALLY MANDATED. THIS DELAY IS TO PREVENT A CRASH IF THE ACCELERATOR SENSOR FAILS IN THE OPEN POSITION. ON NOVEMBER 7, 2007, THE REPRESENTATIVE FROM THE VOLKSWAGEN MANUFACTURER DROVE THE VEHICLE AND DUPLICATED THE FAILURE. THE FAILURE CONTINUED TO OCCUR WHEN DRIVING WITH TWO FEET OR ONE FOOT. THE FAILURE MILEAGE WAS 2,000 AND CURRENT MILEAGE WAS 13,850. EQ-10209410-4200. 12/12/07. UPDATED 12/12/07 *TR

FOR SEVERAL WEEKS, MY 2005.5 VW JETTA TDI HAS BEEN INTERMITTENTLY BEEN LOSING POWER UPON ACCELERATION. UNFORTUNATELY, I NEVER KNOW WHEN THIS IS GOING TO HAPPEN; THUS IT CAN BE VERY DANGEROUS WHEN YOU GO TO PULL INTO TRAFFIC AND HAVE NO ACCELERATION POWER. MY CAR, AS WELL AS MANY OTHER'S CARS WITH THE SAME PROBLEM, HAS BEEN IN THE "SHOP" SEVERAL TIMES WITH NO *FIX* AS OF YET. THOUGH VW AND THEIR NUMEROUS TECHNICIANS KEEP *GUESSING* AND REPLACING PARTS, THE PROBLEMS STILL EXIST. FOR THOSE OF US DRIVING THESE AUTOMOBILES, WE ARE VERY LUCKY IF WE GO WITHOUT CAUSING AN ACCIDENT OR BEING THE CENTER OF AN ACCIDENT WHEN YOU HAVE NO ACCELERATION POWER. *TR

DT*: THE CONTACT STATED WHEN THE ACCELERATOR PEDAL IS DEPRESSED, AFTER BEING STOPPED AT A RED LIGHT, THE VEHICLE WILL MOVE FOR A SPLIT SECOND THEN STOP. IF THE VEHICLE IS TURNED OFF FOR 15 MINUTES, IT WILL GO FOR 10 MILES. THIS IS AN INTERMITTENT PROBLEM. THE VEHICLE HAS BEEN TOWED TO THE DEALERSHIP FOUR TIMES. THE DEALERSHIP IS UNABLE TO DETERMINE A PROBLEM, BUT HAS REPLACED MULTIPLE COMPONENTS. THE DEALERSHIP HAS RESET THE CODES, REPLACED THE THROTTLE BODY CONTROL VALVE MODULE, THE THROTTLE POSITION SENSOR, THE WIRES CONNECTING THE ECM, THE ACCELERATOR PEDAL, 18 CONNECTORS, THE WIRES TO THE PEDAL, BOLTS, AND INSTALLED A HARNESS. THESE EFFORTS HAVE NOT REPAIRED THE PROBLEM AND THE VEHICLE IS CURRENTLY AT THE DEALERSHIP.

DT: THE CONTACT STATED WHEN ACCELERATING BETWEEN 25-30 MPH THE VEHICLE HESITATED AND LURCHED FORWARD. THIS PROBLEM WAS INTERMITTENT IN NATURE. THE VEHICLE HAS BEEN TAKEN TO THE DEALER NUMEROUS TIMES. HOWEVER , THE DEALER WAS UNABLE TO DUPLICATE THE PROBLEM. NO REPAIRS HAVE BEEN MADE. *AK

DT: THE CONTACT OWNS A 2005 VOLKSWAGEN JETTA. HE IS HAVING PROBLEMS WITH THE ACCELERATOR PEDAL. THE VEHICLE WILL NOT ACCELERATE WHEN HE NEEDS IT TO. WHEN HE TURNS THE CAR OFF AND LETS THE COMPUTER RESET THEN START THE VEHICLE IT WILL ACCELERATE. HE TOOK CAR TO A DEALER, AND SINCE THE PROBLEM WAS INTERMITTENT THEY COULD NOT FIGURE OUT THE CAUSE OF THE PROBLEM. DEALER COULD NOT DUPLICATE THE PROBLEM WHILE HAVING THE CAR FOR EIGHT DAYS.*AK *NM
