2010 VOLKSWAGEN JETTA Complaints

MY 2010 VW JETTA TDI WITH AUTOMATIC TRANSMISSION HAS STALLED ON NUMEROUS OCCASIONS WHEN DEPRESSING THE ACCELERATOR PEDAL NEARLY TO THE FLOOR, SO AS TO PASS OR PULL A STEEP HILL. WHEN THIS HAPPENS I IMMEDIATELY LET OFF THE PEDAL AND THE ENGINE REVIVES, BUT WILL NOT ACCEPT FURTHER FULL-THROTTLE INPUTS. *TR

DURING THE FIRST MONTH OF OWNERSHIP, I WAS DRIVING DOWN THE HIGHWAY AT 55 MPH AND PREPARING TO STOP FOR STOPLIGHT, THE CAR STALLED AT SPEED; I ASSUMED THAT IT WAS DUE TO BEING UNACCUSTOMED TO THE GEARING. I HAVE ALSO HAD SEVERAL INSTANCES IN WHICH AFTER THE CAR HAD BEEN SITTING IN THE PARKING LOT DURING WORK, I PULLED OUT AND THE CAR STUMBLED, BUT DID NOT STALL. HOWEVER, I DID NEED TO ENGAGE THE CLUTCH SEVERAL TIMES. ALSO, AFTER THE SAME CIRCUMSTANCES, I PULLED OUT SUCCESSFULLY AND FELT THE CAR LOSE POWER SUDDENLY, AS IF THERE WAS NOT ENOUGH GAS/AIR TO KEEP GOING. *TR

TRAVELING THROUGH PARKING LOT AT APPROXIMATELY 5 MPH, THE ENGINE SUDDENLY TURNED OFF. APPLIED BRAKE, PUT THE AUTOMATIC TRANSMISSION IN PARK AND RESTARTED VEHICLE. EVENT OCCURRED (ONLY TIME) 02-11-2011 AND VEHICLE WAS PURCHASED NEW IN APRIL OF 2010. NO INCIDENT OR COLLISION OCCURRED DUE TO EXTREMELY LOW SPEED. SO FAR, NOTHING DONE TO CORRECT THE FAILURE (AS IT HAPPENED LAST NIGHT). DEALER NOTIFIED 02-12-2011. *TR

I'VE HAD TWO EPISODES OF THE VEHICLE STALLING OUT. THE FIRST TIME, I HAD JUST PULLED OFF OF THE FREEWAY ONTO THE FRONTAGE ROAD AND SLOWED TO A STOP AT A TRAFFIC LIGHT, AND THE ENGINE STALLED OUT. THE SECOND TIME WAS A FEW MONTHS LATER, AND THE ENGINE STALLED OUT EVERY TIME I CAME TO A STOP AT A STOPLIGHT. I CALLED THE DEALER, AND THEY TOLD ME TO HAVE THE CAR TOWED IN. THEY KEPT THE CAR FOR SEVERAL DAYS, AND COULD NOT GET THE SYMPTOM TO OCCUR, SO THEY DID NO REPAIRS.

I HAVE A 2010 JETTA SPORTWAGEN TDI MANUAL TRANSMISSION. I PURCHASED NEW IN FEBRUARY 2010. I AM NOT SURE OF THE DATES BUT THE VEHICLE HAS STALLED OR JUST TURNED OFF TWICE SINCE I HAVE OWNED IT WHILE DRIVING AROUND TOWN. IT DID START BACK UP AS SOON AS I TURNED IT COMPLETELY OFF AND BACK ON. I DIDN'T THINK IT WAS A MAJOR DEAL THE FIRST TIME IT HAPPENED AND THAT I MAY HAVE JUST STALLED IT. WHEN IT HAPPENED THE SECOND TIME I QUESTIONED THE DEALER. THEY SAID UNLESS THEY COULD GET IT TO REPLICATE THE PROBLEM, THEY DIDN'T KNOW. THE OTHER ISSUE THAT I BELIEVE MAY BE RELATED HAPPENS ALL THE TIME. UNDER NORMAL DRIVING WHICH HAPPENS ATLEAST EVERY DAY I HAVE A BLIP IN THE THROTTLE. IT ALMOST FEELS LIKE THERE IS AN AIR POCKET IN THE FUEL THAT IS LIKE A HICCUP UNDER THROTTLE. IT IS RANDOM BUT AS I SAID HAPPENS ATLEAST ONCE A DAY. THE DEALER HAS DONE NOTHING ABOUT THESE ISSUES BECAUSE THEY CANNOT REPLICATE THE ISSUE. *TR

WHEN ATTEMPTING TO ACCELERATE AWAY FROM A STOP MY MANUAL TRANSMISSION 2010 VOLKSWAGEN JETTA SPORTWAGEN TDI WILL STALL. THIS OFTEN OCCURS JUST AS THE VEHICLE ENTERS THE INTERSECTION. *TR

INTERCOOLER PIPING ACCUMULATES AN OIL/WATER SLUDGE MIXTURE DURING COLD WEATHER DRIVING. WHILE PARKED AFTER DRIVING THE SLUDGE COLLECTS AT THE LOWEST POINT IN THE PIPING. IF TEMPERATURES ARE BELOW FREEZING, THE SLUDGE FORMS A PLUG WHICH PREVENTS THE CAR FROM STARTING. IF IT IS ABOVE FREEZING, THE SLUDGE IS INGESTED INTO THE ENGINE WHERE IT CAUSES HARD STARTS AND ROUGH RUNNING. THIS HAS OCCURRED FIVE TIMES IN THE LAST TWO MONTHS, DEALER HAS BEEN UNABLE TO DETERMINE CAUSE OR EFFECT A REPAIR OTHER THAN PERIODICALLY REMOVING HOSES TO CLEAN OUT ACCUMULATED SLUDGE. *TR

SUCCESSFULLY STARTING AND DRIVING THE CAR FOR 3 DAYS OF BELOW FREEZING TEMPS AT 40MPH AVERAGE. PUT CAR IN 40DEG GARAGE OVERNIGHT. STARTED CAR IN THE MORNING IN GARAGE, IT RAN FOR ABOUT 3-5 SECONDS THEN STOPPED. RESTART ACTED LIKE DEAD BATTERY; HALF TURN OF CRANK, THEN NOTHING. SUSPECTING A DEAD BATTERY, I PUT A CHARGER ON AND TRIED AGAIN HALF AN HOUR LATER; STILL NO START, JUST HALF TURN THEN NOTHING. TRIED AGAIN ABOUT EVERY HALF HOUR FOR 3 HOURS UNTIL IT FINALLY STARTED, THEN IT SEEMED TO BE RUNNING ON 3 CYL FOR ABOUT 15-20 SEC UNTIL IT STARTED TO RUN SMOOTH. TOOK TO DEALER WHERE THEY TESTED BATTERY AND CHARGING SYSTEM; EVERYTHING WITHIN SPECS AND NO CODES. THEY KEPT CAR OUTSIDE OVERNIGHT AT 20 DEGREES AND IT STARTED RIGHT UP THE NEXT MORNING. I INVESTIGATED THIS ISSUE ON SEVERAL TDI FORUMS AND IT SEEMS THIS IS ATTRIBUTED TO ICE FORMING IN THE INTERCOOLER THEN THAWING WHEN WARMED UP. ENGINE WILL START NORMALLY UNTIL IT INGESTS THE WATER/VAPOR THAT SHUTS IT DOWN. SEVERAL OWNERS ARE REPORTING HALF CUP TO TWO CUPS OF WATER DRAINED OUT OF INTERCOOLER HOSES. SEVERAL OWNERS ARE REPORTING ENGINE EITHER SHUTTING DOWN OR GOING INTO LIMP MODE ON HIGHWAY AFTER ICE BLOCKS INTAKE SUFFICIENTLY. MOST ARE SUSPECTING THE LP EGR CIRCUIT THAT IS PUMPING MOIST AIR BACK INTO THE INTAKE/INTERCOOLER CAUSING CONDENSATION TO ACCUMULATE THEN FREEZE. I NOTIFIED DEALER WHEN THEY HAD THE CAR AND THEY DID NOT INVESTIGATE WATER IN INTERCOOLER AS REQUESTED. I SUSPECT THIS IS HYDROLOCKING THE ENGINE AND THAT SERIOUS ENGINE DAMAGE WILL OCCUR IF THIS CONTINUES DURING THE COLD MONTHS. SEVERAL FORUM MEMBERS IN CANADA ARE REPORTING THAT VW OF USA KNOWS ABOUT THIS AND IS WORKING ON A SOLUTION BUT NOBODY HAS SEEN ANYTHING YET. SEVERAL DEALERS ARE RECOMMENDING THE REMOVAL OF THE FRESH AIR INTAKE PIPE TO DRAW WARM, UNDERHOOD AIR INTO THE INTAKE; THIS DOES NOT SEEM TO AFFECT THE ICING AS THE MOISTURE SEEMS TO BE COMING FROM THE EXHAUST STREAM VIA THE LP EGR. *TR

THE ENGINE SOMETIMES SKIPS OR HESITATES WHILE DRIVING - IT SEEMS AS IF THE FUEL IS GETTING CUT OFF MOMENTARILY. THE ENGINE SKIPS AND STUTTERS LIKE IT'S ABOUT TO STALL. IT HAS NOT ACTUALLY STALLED YET WHILE I'M DRIVING, BUT SOMETHING IS OBVIOUSLY WRONG. THE ENGINE IS THE 4 CYLINDER 2.0 TDI DIESEL. 2010 VW JETTA SPORTWAGEN. *TR
