AT APPROX 60K CHECK ENGINE LIGHT CAME ON READ "EMISSIONS WORKSHOP". DEALER HOOKED UP COMPUTER AND TOLD ME IT WAS AN OXYGEN SENSOR AND SOME OF THE VACUUM HOSES HAD TO BE REPLACED. I TOOK THE VEHICLE TO A VW SPECIALTY SHOP AND THEY CONFIRMED THE O2 SENSOR PROBLEM AND REPLACED A FEW VACUUM HOSES. THE CARS COMPUTER WAS CLEARED AND TWO MONTHS LATER BOTH THE CHECK ENGINE LIGHT AND EMISSIONS WORKSHOP INDICATORS WERE BACK. SHOP HOOKED UP TO THEIR COMPUTER AND CONFIRMED THAT NOW A PRE CAT O2 SENSOR WAS BAD. TWO SENSORS IN THREE MONTHS, BOTH MORE THAN $200 TO REPLACE IS UNACCEPTABLE. VW IS SUPPOSED TO HAVE EXTENDED PORTIONS OF ITS WARRANTIES BUT THE DEALER CLAIMS IT DOESN'T COVER THESE PARTS OR REPAIRS. THE CAR HAS APPROX. 62,000 MILES. FROM WHAT I HAVE HEARD THIS IS A COMMON PROBLEM THAT VW SHOULD BE HELP ACCOUNTABLE FOR. *JB

BY THE TIME AN EXIT WAS REACHED ENGINE WAS SPUTTERING AND KNOCKING. MILEAGE IS APPROXIMATE -- CAR IS AT DEALER ABOUT 50 MILES DISTANT. AR IS WITHIN WARRANTY MILEAGE AND YEARS (7 YEARS/70,000 MILES FOR POWER TRAIN). VOLKSWAGEN IS REFUSING TO PROVIDE WARRANTY COVERAGE BECAUSE MILEAGE WAS NOT RECORDED ON RECEIPTS AT TIME OF OIL CHANGES.

IN JULY 2003 MY 2001 VOLKSWAGEN NEW PASSAT 1.8L TURBO HAD SYMPTOMS RELATED TO OIL PRESSURE PROBLEMS. AS I WAS TRAVELING ON VACATION THE CAR GAVE WARNING OF THIS SITUATION AND THE SYSTEM ADVISED THAT THE CAR BE STOPPED IMMEDIATELY. I STOPPED THE CAR AND BEGAN PURSUING OPTIONS TO GET THE CAR TO THE NEAREST DEALERSHIP. THE DEALERSHIP DIAGNOSED THE PROBLEM AS OIL SLUDGE. THE REPAIR WAS AS SIMPLE AS CLEANING THE OIL PUMP STRAINER AND OIL PAN. THE REPAIR COST APPROXIMATELY $500.00. NOW, SOME 20K MILES LATER MY CAR HAD ANOTHER OIL RELATED ISSUE. THIS TIME THE OIL COOLER MALFUNCTIONED AND RUPTURED CAUSING $8,000 - $10,000 IN REPAIR COST. OF COURSE THE CAR IS NOT UNDER WARRANTY AND RECENT ACTIONS BY VOLKSWAGEN TO EXTEND WARRANTIES FOR OIL SLUDGE DO NOT INCLUDE THE OIL COOLER. THE OIL SLUDGE ISSUE HAS BEEN IDENTIFIED AS A MAJOR CONCERN OF VOLKSWAGEN OF AMERICAN BY THEIR ACTIONS TOWARD THE WARRANTY EXTENSION, BUT THEY ARE AVOIDING PARTS AND THE MECHANICAL OPERATIONS THAT COULD LEAD TO THE PROBLEM BEING CORRECTED. OBVIOUSLY OIL THAT IS NOT PROPERLY COOLED WILL BREAK DOWN QUICKER THAN OIL RUNNING AT MORE ACCEPTABLE TEMPERATURES. CURRENTLY, VOLKSWAGEN CAN MAKE NO CONCLUSIVE ANALYSIS AS TO THE RELATIONSHIP BETWEEN AN OIL COOLER MALFUNCTION AND OIL SLUDGE. THIS WOULD BE KEY IN DETERMINING THE RESPONSIBILITY FOR THE CAR REPAIRS. VOLKSWAGEN OF AMERICA'S CUSTOMER CARE ADVOCATES HAVE REFERRED ME TO MY DEALERSHIP ON TWO OCCASIONS AND MY DEALERSHIP SEEMS TO BE UNABLE TO MAKE 100% CONCLUSIVE DECISIONS. I BELIEVE IT IS VOLKSWAGENS RESPONSIBILITY TO GUARANTEE THEIR PRODUCTS. THEY ARE IN NO POSITION TO AVOID RESPONSIBILITY ESPECIALLY AFTER ALLOWING THE OIL SLUDGE ISSUE TO CONTINUE FROM 1998 MODELS CARS TO CURRENT 2004 MODELS WITHOUT OFFERING CONSUMER ASSISTANCE. SIX YEARS IS A LONG TIME TO HAVE POTENTIALLY SERIOUS MECHANICAL ISSUES UNADDRESSED. THANK YOU. *JB

VEHICLE DIED WHILE DRIVING ON 45 MPH ROAD. STARTER AND ENGINE TURN, BUT WOULD NOT RUN. ADVISED DEALER THAT THIS HAPPENED 1 YEAR AGO AND ENGINE FUSE AND HORN FUSE HAD TO BE REPLACED. NO CODES WERE IN THE COMPUTER. DEALER REPLACED FUSE S232 AND CAR STARTED. DURING ROAD TEST, CAR DIED AGAIN. FUSE S232 BLEW AGAIN AND DEALER FOUND ECM AND HARNESS MELTED AND WAS SMOKING. DEALER REPLACED ECM, HARNESS AND FUSE AND CAR RAN. WHEN CUSTOMER RECEIVED THE CAR, THE CRUISE CONTROL AND DASH LIGHTS WERE INOPERATIVE. DEALER REPROGRAMMED CRUISE AND FIXED WIRING OF DASH LIGHTS UNDER WARRANTY AFTER MUCH ARGUMENT. DEALER DID NOT KNOW CAUSE OF MISHAP. THIS IS THE 2ND TIME THE CAR HAS DIED WHILE TRAVELLING ON BUSY ROADS. I WAS NEARLY REAR-ENDED TWICE AS I PULLED THE CAR OFF THE HIGHWAY.*AK

In July 2010, the Agency opened PE10-027 to investigate allegations of coil on plug (COP) ignition coil fires in MY2002-2003 VW Passat vehicles.The investigation was upgraded in January 2011 to include all MY2001-2007 4-cylinder VW Passat, gasoline, turbo-charged vehicles.Based on the analysis of VW's response, and including ODI's consumer complaints, ODI has since identified 135 unique engine fire reports attributable to the COP coils.After further review of the details as contained in each report, ODI determined that 43 of the 135 fire reports were actual fire/flame incidents, 83 fire reports were thermal events (smoke, spark, heat or wire melt), and another 9 fire reports were undetermined in severity due to the lack of information.These COP coil fires were characterized as initiated from within the COP coil circuit located at the top of the engine block and below the plastic engine cover.The fires observed were contained in the engine compartment and did not reach into the passenger compartment in contrast to those caused by an overheated catalytic converter examined in ODI?s investigation in 2007 and 2008.There were no reports of crashes or personal injury in this examination.A safety-related defect has not been identified at this time and further use of agency resources does not appear to be warranted.Accordingly, this investigation is closed.The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist.The agency will monitor this issue and reserves the right to take further action if warranted by the circumstancesSee the Closing Report for additional details.

BY LETTER RECEIVED ON JUNE 24, 2005, MR. RONALD M. STRICKLAND OF RALEIGH, NC, SUBMITTED A PETITION REQUESTING THAT THE AGENCY INVESTIGATE THE PERFORMANCE OF THE IGNITION COIL PLUGS ON MODEL YEAR (MY) 2000-2003 VOLKSWAGEN JETTA, GOLF AND PASSAT SEDANS.THE PETITIONER ALLEGES THAT HE HAD EXPERIENCED MULTIPLE STALLING EVENTS AS A RESULT OF ONE OR MORE IGNITION COIL PLUGS MALFUNCTIONING ON HIS 2002 VW JETTA SEDAN.AS A RESULT OF THE ENGINE STALLING, THE PETITIONER EXPERIENCED A LOSS OF POWER STEERING AND INCREASED BRAKING EFFORTS WHEN HE PULLED THE VEHICLE OVER TO THE SIDE OF THE ROAD TO CONTROL THE VEHICLE.AFTER A FEW MINUTES PARKED ON THE SHOULDER HE WAS ABLE TO RESTART THE VEHICLE ALTHOUGH THE ENGINE OPERATED AT REDUCED POWER.VW ISSUED A CUSTOMER SATISFACTION CAMPAIGN (CSC) ON JANUARY 31, 2003 TO INSTRUCT THEIR DEALERSHIPS TO INSPECT THE VEHICLES FOR ANY MALFUNCTIONING IGNITION COIL PACKS AND TO REPLACE THEM AT NO COST TO THE CONSUMER.CONSUMERS WERE NOTIFIED TO BRING THEIR VEHICLES TO THEIR DEALERSHIPS VIA OWNER LETTERS MAILED OUT ON JUNE 6, 2003.WHILE VW INITIALLY INSTRUCTED THE DEALERSHIPS TO ONLY REPLACE THE MALFUNCTIONING IGNITION COIL PACKS, A REVISED CSC WAS ISSUED TO DEALERSHIPS IN DECEMBER 2003 AND JANUARY 2004, INSTRUCTING DEALERSHIPS TO REPLACE ALL IGNITION COIL PACKS REGARDLESS OF THEIR PERFORMANCE.A REMINDER TO THE DEALERSHIPS WAS SENT BY VW ON APRIL OF 2004.ALTHOUGH THE CONCERNS OF THE PETITIONER COULD THEORETICALLY CREATE A SAFETY PROBLEM, THE RISK IS VERY SMALL, DUE TO THE ENGINE STILL RUNNING ON EITHER 3, 5, OR 7 CYLINDERS.THERE ARE NO REPORTED CRASHES OR INJURIES DUE TO THE ALLEGED DEFECT.ONCE DRIVERS ARE AWARE OF THE PROBLEM (LOSS OF POWER DUE TO ONE OF THE IGNITION COIL PACKS MALFUNCTIONING), DRIVERS ARE ABLE TO TAKE PRECAUTIONARY AND COMPENSATORY MEASURES AND STILL MAINTAIN CONTROL OF THEIR VEHICLES.IN ADDITION, FOUR FIRES WERE REPORTED TO ODI.THESE WERE IGNITION COIL BURNOUTS WITH NO ADDITIONAL DAMAGE TO THE VEHICLE AND WERE LOCALIZED ON TOP OF THE ENGINE. DURING THE LAST 24 MONTHS THE NUMBER OF STALL AND DRIVABILITY COMPLAINTS REPORTED TO ODI HAS GREATLY DIMINISHED FROM A PEAK OF 195 IN JANUARY OF 2003 TO ONLY 3 IN AUGUST OF 2005.THIS COINCIDES WITH THE CSC RELEASED BY VW.A SAFETY-RELATED DEFECT TREND HAS NOT BEEN IDENTIFIED AT THIS TIME AND FURTHER USE OF AGENCY RESOURCES DOES NOT APPEAR TO BE WARRANTED.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT NO SAFETY-RELATED DEFECT EXISTS.THE AGENCY RESERVES THE RIGHT TO TAKE FURTHER ACTION IF WARRANTED BY THE CIRCUMSTANCES.

THIS INVESTIGATION INVOLVES THE VOLKSWAGEN (VW) PASSENGER SUPPLEMENTAL INFLATABLE RESTRAINT (PSIR) LID UTILIZED IN MY 1998-2002 VW PASSAT.THE PSIR LID MAY DETACH FROM THE INSTRUMENT PANEL DURING AIR BAG DEPLOYMENT.THE OFFICE OF DEFECTS INVESTIGATION (ODI) OF THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION (NHTSA) OPENED THE PRELIMINARY EVALUATION ON MAY 23, 2003 TO DETERMINE WHETHER ALLEGED PSIR LID DETACHMENT PRESENTS AN UNREASONABLE SAFETY RISK TO PASSENGERS IN THE VEHICLE.ODI?S INVESTIGATION REVEALS THAT DETACHMENT OF THE PSIR LID DURING AIR BAG DEPLOYMENT MAY OCCUR FOR TWO REASONS: 1) THE SHAPE OF THE PSIR LID, AND THE LENGTH OF THE ATTACHING TETHER, MAY SNAG THE AIR BAG DURING DEPLOYMENT APPLYING ADDITIONAL PRESSURE ON BOLTS THAT FASTEN THE LID TO THE INSTRUMENT PANEL (IP); AND/OR 2) THE ORIGINAL PSIR LID DESIGN (SUBJECT VEHICLES) UTILIZED SIX GRADE 4.8 MM CARBON STEEL TACK WELD BOLTS WHICH MAY NOT BE AS STRONG AS THE NEW DESIGN PSIR LID CONSISTING OF SIX GRADE 8.8 MM CARBON STEEL PRESS BOLTS THAT ARE HEAT TREATED.ODI CONCLUDES THAT DETACHMENT OF THE PSIR LID IS A DEFECT BECAUSE THE LID SHOULD REMAIN ATTACHED TO THE IP AFTER DEPLOYMENT OF THE AIRBAG.HOWEVER, AFTER ANALYZING VW?S RESPONSES, AND TEST DATA COLLECTED BY VW AND FAURECIA, THE PSIR LID SUPPLIER, ODI BELIEVES THAT FURTHER INVESTIGATION WOULD NOT LIKELY IDENTIFY A SAFETY-RELATED DEFECT TREND BECAUSE A DETACHED PSIR LID AND PARTS DO NOT PROJECT TOWARDS A PASSENGER DURING DEPLOYMENT OF THE AIRBAG.THE TEST DATA SHOWS THAT THE AIRBAG PUSHES A DETACHED PSIR LID UPWARDS INTO THE WINDSHIELD DURING DEPLOYMENT, AND AWAY FROM THE PASSENGER COMPARTMENT.IT IS HIGHLY UNLIKELY THAT A PASSENGER WOULD CONTACT THE PSIR LID OR ASSOCIATED PARTS DURING AIR BAG DEPLOYMENT.THEREFORE THIS ENGINEERING ANALYSIS (EA 03-020) IS CLOSED.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT A SAFETY-RELATED DEFECT DOES NOT EXIST.
