2014 Volkswagen Jetta Cruise Control Problems

Your car has unexpectedly accelerated to near maximum engine speed without you pressing the pedal, and the brakes failed to slow it down. This has happened multiple times, including once confirmed by a shop manager during a test drive. Diagnostic codes pointed to emissions system issues (EGR), and the dealer is demanding a $6,000 DPF replacement before investigating the actual acceleration problem, though emissions components shouldn't affect throttle control. Resolving this will require thorough diagnostic testing to identify the root cause of the uncontrolled acceleration and brake failure.

Your car has unexpectedly accelerated on multiple occasions—once from 45 to 70 MPH and again from 25 to 50 MPH—without you pressing the gas pedal, and the brakes failed to slow or stop the vehicle during these incidents. The first time, your car lost all power and wouldn't restart; the second time, a check engine light appeared. An independent mechanic found no fault, and the dealer was unable to identify a cause despite diagnostic testing.

WHAT HAPPENS IS MY CAR SHUT DOWN IN THE MIDDLE OF TRAFFIC AFTER ME GETTING GAS SOMETIMES AND ENGINE LIGHT APPEAR. WHEN SHUTTING DOWN A QUICK FLASH OF BATTERY LIGHT SHOWS UP, NOW ENGINE LIGHT IS ON LONGER AND THE CAR POWER JUST SHUT EVERYTHING DOWN AS IF THE BATTERY IS DEAD NOTHING WORK BUT WITH A JUMP I WAS ABLE TO MOVE CAR AND WHEN I CUT IT OFF IT SHUT DOWN AGAIN THIS BEEN GOIN ON FOR ABOUT 1 MONTH ADVANCE AUTO TEST IT AND SAID IT HAD SOMETHING TO DO WITH MY FUEL PUMP DON'T REMEMBER THE CODE BUT ENGINE KEEP COMING ON VERY OFTEN.

The camshaft sensor is faulty, which then causes the cruise control to stop working, the traction control to turn off, makes the car unable to accelerate, then the steeling wheel begins to shake and the engine to shut down. Which is extremely dangerous while driving. I was luckily able to pull over, but I was almost rear ended because the car stopped accelerating. My check engine light didn’t come on until AFTER this incident occurred.

THE EPC LIGHT CAME ON AND I PULLED TO SIDE AND TURN THE CAR OFF. WHEN I TURNED CAR BACK ON THE LIGHT WAS OFF. THEN IT CAME ON ANOTHER TIME AND I NOTICE WHEN TRYING TO ACCELERATE TO THE CAR IS LAGGING. SO I DECIDED TO TAKE TO VW DEALER IN MARTINEZ GA AND THEY SAID I HAD GOTTEN SOME BAD GAS, THEY ADDED SOME 44K ADDITIVE TO THE TANK. I WAS ONLY USING SHELL GAS, SO I WAS TOLD TO TRY ANOTHER BRAND THAT WAS A TOP TIER GAS. I TRIED CITGO AND THEY HAD THE TOP TIER STICKER ON THE TANK. THE CAR DROVE GOOD FOR A DAY AND A HALF THEN THE LIGHT CAME ON AGAIN WITH ALSO THE CHECK ENGINE LIGHT AND THE CAR STARTED TO SHAKE. I HAVE REACHED OUT TO THE DEALERSHIP ONLINE AND I GOT A CALL FROM A SALES REP, WHO SAID SHE COULD HELP ASSIST WITH PURCHASING A SAFER OR NEW CAR. I DON'T WANT TO BUY ANOTHER CAR AT THIS TIME. I ONLY HAVE 125K MILES AND THE CAR WAS RUNNING FINE. I LOOKED ON THE INTERNET AND I SEE THAT THIS IS NOT A NEW ISSUE WITH VW JETTA FROM 2014 TO 2018 AND VW HAS NOT FIGURED OUT THE FIX FOR IT. I WAS SUPPOSED TO GET A CALL BACK FROM THE SERVICE ADVISOR AND I HAVE NOT HEARD FROM HIM. SO AT THE PRESENT TIME I AM DRIVING AND PULLING TO THE SIDE OF THE ROAD TO GET THE LIGHT TO TURN OFF. WHEN I GET HOME I TRY NOT TO GO ANYWHERE OTHER THAT TO WORK AND BACK.

THE ENGINE MAY IDLE AND STUMBLE UPON ACCELERATION. THIS MAY BE DUE TO FAULTY ENGINE CONTROL MODULE SOFTWARE MISADJUSTING THE VALVE TIMING." THI IS THE CURRENT SAFETY RECALL FOR THE SAME MAKE MODEL AND YEAR OF MY CAR, HOWEVER, MY VIN HAS NOT BEEN INCLUDED. THIS IS THE ISSUE WITH MY CAR. IT WILL HAPPEN WHILE IN PARK, WHEN SLOWING DOWN TO STOP. MY CAR HAS STALLED AS A RESULT AT A STOP SIGN OR AT A LIGHT. LAST TIME THIS HAPPENED WAS TODAY.

PARKING THE CAR IN PARKING SPACE. CAR MADE EXTREMELY LOUD NOISE (LIKE A BACKFIRE) AND THEN AUTO ACCELERATED. TRIED HITTING THE BRAKE BUT BRAKE DID NOT DECOMPRESS. HIT A PARKED CAR IN FRONT OF ME. *TR

STOPPED FOR PEDESTRIAN CROSSING THE STREET, NORMAL STOP, TOOK MY FOOT OFF THE BRAKE, STEPPED ON THE GAS AND NOTHING! CAR STALLED AND I COULD NOT MOVE. TRAFFIC WAS BACKING UP BEHIND ME AND THE CAR WOULDN'T MOVE. PUT IT IN PARK, TURNED IT OFF AND ON, AFTER TWO MINUTES IT FINALLY WORKED WHEN I STEPPED ON THE GAS. DID THE SAME THING ABOUT TWO WEEKS LATER...TWICE IN ONE DAY! TOOK IT TO THE DEALER THE SAME DAY IT HAPPENED FIRST, TOLD ME I HAD AN ENGINE SOFTWARE RECALL, SPENT TWO HOURS AT THE DEALER. THEY TOLD ME IT WAS "FIXED." TWO WEEKS LATER, AT A STOP SIGN AND THEN A RED LIGHT, DID THE SAME THING. BROUGHT IT TO ANOTHER DEAL THAT NIGHT, WHO TOLD ME THERE WAS NO LOANER CARS AVAILABLE, TOOK THE CAR FOR THREE DAYS! THEY CALLED BACK AND SAID THEY COULD NOT RECREATE THE PROBLEM, THEREFORE THEY WERE GIVING ME BACK THE CAR. I DON'T FEEL SAFE!! HAVE HAD NUMEROUS OTHER PROBLEMS WITH THE CAR SINCE OCTOBER 2013, HAS BEEN IN THE SHOP 8 TIMES IN 6 MONTHS.... NOW AFFECTED BY THE O-RING RECALL! *TR
