FIRST INCIDENT: OCCURRED IN FALL 2012, EXACT DATE UNKNOWN. SLOWING TO TURN RIGHT, VEHICLE STALLED WITHOUT WARNING. POWER STEERING WAS NOT RESPONDING. IT WAS TAKEN TO DEALERSHIP THE NEXT DAY. VEHICLE WAS EVALUATED, NOTHING WAS FOUND. WE WERE TOLD THAT THEY COULD SEE SOME SORT OF POWER INTERRUPTION, BUT COULD FIND NOTHING WRONG WITH ANY OF THE SYSTEMS INVOLVED. SECOND INCIDENT: OCCURRED ABOUT 1 MONTHS AFTER FIRST INCIDENT. WHILE SLOWING TO A STOP, INTENDING TO MAKE A LEFT TURN OUT OF PARKING LOT, AGAIN VEHICLE STALLED WITHOUT WARNING. DID NOT TAKE CAR TO DEALERSHIP, AS IT HAD JUST RECENTLY BEEN EVALUATED. GAS WAS < 1/8 TANK FILLED, AND PARKING LOT EXIT WAS ON A SLIGHT DECLINE, SUSPECTED MAYBE IT WAS RELATED TO LOW FUEL, AND WE TRIED TO KEEP THE CAR ABOVE 1/4 TANK FULL AT ALL TIMES THEREAFTER. THIRD INCIDENT: OCCURRED 4/29/14. SLOWING TO PULL INTO A PARKING SPACE, AGAIN ENGINE STALLED WITHOUT WARNING. I NOTED THAT THE BATTERY INDICATOR LIGHT ON THE DASHBOARD LIT UP SLIGHTLY BEFORE OR AS CAR WAS STALLING. POWER STEERING FAILED AS WELL WHEN CAR STALLED. RADIO / HEATER / OTHER ELECTRONICS SEEMED UNAFFECTED AFTER A BRIEF FLICKER. FOURTH INCIDENT: OCCURRED ABOUT 20 MINUTES LATER ON 4/29/14. SLOWING FOR A STOP LIGHT, VEHICLE STALLED UNEXPECTEDLY. CAR IS DUE FOR INSPECTION, APPOINTMENT IN 2 DAYS. DEALERSHIP ASKED TO INVESTIGATE STALLING AS WELL. *JS

DRIVING ON HIGHWAY ON 12/15/13 AND AS I ACCELERATED, I LOST POWER AND "CHECK ENGINE LIGHT" CAME ON. CAR FELL TO 50MPH AND I EXITED HIGHWAY IMMEDIATELY, STOPPED THE CAR, RE-STARTED AND THE CAR AND LIGHT WAS STILL ON. SHOWED ERROR CODE G450 AND THE "EXHAUST PRESSURE SENSOR 1" WAS REPLACED BY DEALER IN JANUARY 2014. GLOW PLUG LIGHT ALSO CAME ON INTERMITTENTLY AT THAT TIME. TWO MONTHS LATER (FEBRUARY, 2014), "GLOW PLUG LIGHT" CAME ON AGAIN INTERMITTENTLY. TURNED OFF CAR AND STARTED IT AGAIN AND LIGHT WENT OUT. DEALER SAYS P0237 CODE MEANS INTERMITTENT FAILURE OF "BOOST PRESSURE SENSOR" AND "SENSOR HARNESS". VW ADVISES THE CAR IS NOT DRIVABLE DUE TO UNPREDICTABLE PERFORMANCE OF TURBOCHARGER ON ENGINE PERFORMANCE DUE TO FAILURE OF THIS SENSOR. THE LOSS OF POWER HAS BEEN DOCUMENTED WIDELY FOR THIS ENGINE (PUMP, CARBONIZED INTAKE, OTHER?), BUT VW HAS ACCEPTED NO RESPONSIBILITY FOR THE PROBLEM. CAR IS 4 YEARS OLD WITH 48,900 MILES. REPAIRS ARE APPROACHING $1000 AT THIS TIME. *TR

WHILE DRIVING MY 2010 VW JETTA TDI AT 45 MPH THE GLOW PLUG LIGHT BEGAN TO FLASH WITH NO WARNING AND ENGINE POWER BECAME DRAMATICALLY REDUCED. I WAS UNABLE TO MAINTAIN SPEED ON A BUSY ROADWAY AND WAS FORCED TO MAKE AN ABRUPT EXIT FROM THE ROAD TO AVOID CAUSING AN ACCIDENT. USING BACK ROADS WITH LOW SPEED LIMITS I WAS ABLE TO REACH A VOLKSWAGEN DEALERSHIP. AFTER ARRIVING THE VEHICLE COULD NOT BE RESTARTED. AFTER 3 DAYS OF INSPECTION IT WAS DETERMINED THAT THE HIGH PRESSURE FUEL PUMP HAD FAILED AND THE METAL SHAVINGS FROM THE FAILED PUMP CONTAMINATED THE ENTIRE FUEL SYSTEM AND CLOGGED IT WITH RUST. EVEN THOUGH THE VEHICLE WAS OUT OF WARRANTY, VOLKSWAGEN OF AMERICA COVERED THE COST OF THE REPAIR WHICH ENTAILED REPLACING THE ENTIRE FUEL SYSTEM. THE TECHNICIAN INFORMED ME THAT THIS WAS A KNOWN PROBLEM WITH THE TYPE OF HIGH PRESSURE FUEL PUMP INSTALLED ON MY CAR WHICH IS WHY VWOA WAS COVERING THE REPAIR EVEN THOUGH THE VEHICLE WAS OUT OF WARRANTY AND THERE WAS NO RECALL. GIVEN THE HIGH POTENTIAL FOR INJURY WHEN THIS KNOWN FAULT OCCURS, I DO NOT UNDERSTAND WHY ALL VEHICLES (WHICH INCLUDE ALL 2010+ AUDI AND VW TDI ENGINES) THAT FEATURE THIS FAULTY FUEL PUMP HAVE NOT BEEN SUBJECT TO A RECALL TO HAVE THE PROBLEM REPAIRED. *TR

EA18003 · Air Bag Clockspring Failure

Opened Apr 18, 2018 · No close date supplied

Status: open (inferred from source dates) · Air Bags; Air Bags:frontal; Air Bags:frontal:driver Clockspring/spiral Cassette

In August 2015, Volkswagen Group of America, Inc. (Volkswagen) launched Safety Recall 15V-483 to address the loss of the protection provided by the front driver air bag in several models due to the failure of the clockspring.Debris entry into the steering wheel hub can result in contamination and ultimately failure of the clockspring in 2010-2014 Model Year (MY) CC, Passat, Eos, Golf, GTI, Tiguan, Jetta and Jetta Sportwagen models.Contamination of the clockspring can cause the ribbon cable to tear resulting in loss of the electrical connection to the front driver air bag and any steering wheel mounted controls.The loss of the electrical connection to the front driver air bag will result in illumination of the air bag warning light and will prevent operation of the front driver air bag in a crash of sufficient severity requiring a commanded deployment.In November 2017, the Office of Defects Investigation (ODI) opened a Recall Query (RQ17-009) after the agency received 90 complaints alleging failure of the clockspring in the subject models.Several of the complaints allege failure of the clockspring after receiving the recall remedy.The majority of the complaints allege the same failure mode without being included in the original recall, 15V-483.In its March 2018 response to ODI's Information Request under the Recall Query, Volkswagen provided approximately 700 consumer complaints and field reports on the recalled vehicles.These reports allege clockspring failure similar to the NHTSA reports described above.To date, NHTSA has received approximately 154 allegations of clockspring failure since the recall has launched.The total of 852 reports shown in the table above eliminates 6 duplicative reports received by ODI and the manufacturer.An Engineering Analysis has been opened to further evaluate the scope and effectiveness of the remedy associated with 15V-483 and perform a thorough review of the design changes implemented by Volkswagen and its suppliers to address this issue.The ODI complaints cited above can be viewed at www.NHTSA.gov under the following ODI identification numbers: 11080741, 11079877, 11079805, 11079124, 11076709, 11076645, 11076297, 11076249, 11076133, 11075756, 11075726, 11075358, 11075259, 11075055, 11074920, 11074565, 11073090, 11072745, 11072457, 11072089, 11071933, 11071880, 11071630, 11071592, 11067396, 11067061, 11066738, 11066601, 11066511, 11065909, 11065871, 11065262, 11064701, 11064564, 11064544, 11064531, 11063961, 11063501, 11063095, 11062772, 11062464, 11062353, 11062344, 11061463, 11061310, 11061311, 11060735, 11058154, 11057519, 11057477, 11057341, 11056793, 11056243, 11056063, 11055639, 11054279, 11052812, 11052678, 11052384, 11052228, 11051336, 11051155, 11051074, 11048803, 11047037, 11044226, 11043653, 11039142, 11033893, 11033330, 11032548, 11025475, 11025356, 11024647, 11023423, 11020570, 11020312, 11019415, 11019067, 11015441, 11015431, 11014595, 11014016, 11013709, 11013415, 11012596, 11011753, 11006668, 11006521, 11006307, 11006181, 11005301, 11003865, 11001780, 11001783, 11001334, 10994184, 10993360, 10993524, 10992490, 10985926, 10983678, 10981220, 10980831, 10980941, 10980549, 10979418, 10971152, 10967344, 10967155, 10959968, 10958624, 10957279, 10956488, 10949129, 10947562, 10945122, 10936498, 10936543, 10933950, 10927311, 10925421, 10924034, 10915612, 10915569, 10911171, 10902066, 10898733, 10896537, 10896510, 10895526, 10893938, 10891686, 10864967, 10863742, 10861984, 10851242, 10822505, 10821562, 10818403, 10795068, 10794402, 10788738, 10787804, 10782544, 10780725, 10780145, 10779145, 10776477, 10775448, 10763492, 10763423, 10763289, 10762670, 10760644, 10758777, 10749901, 10748922

PE11023 · Diesel Fuel Injector Line Leakage

Opened Aug 2, 2011 · Closed Dec 2, 2011

Status: closed (inferred from source dates) · Fuel System, Diesel

By letter dated October 3, 2011, Volkswagen Group of America, Inc. (VW) notified the National Highway Traffic Safety Administration (NHTSA) that it will conduct a safety recall to address a defect in approximately 168,275 model year (MY) 2009-2012 Volkswagen Jetta, Jetta Sportwagen, Golf, and Audi A3 vehicles equipped with the 2.0L TDI Common Rail Clean Diesel engine (NHTSA Recall No. 11V-490).The recalled Jetta and Jetta Sportwagen vehicles were built from May 2008 through September 2011, the Golf vehicles were built from May 2009 through September 2011, and the Audi A3 vehicles were built from September 2009 through September 2011.According to Volkswagen, in U.S. applications of the above cited TDI vehicles including engine codes CJAA and CBEA, the fuel injection pulses could coincide with the natural frequency of the injector line #2 in specific load and RPM conditions.This resonance creates additional stress on the fuel line which a small number of parts (based on the statistic spread of line strength) cannot withstand over its lifetime.As a contributing factor, VW indicated that a supplier used tube material with scratch marks from a grinding process during certain production periods.Lines manufactured in these periods were installed in vehicles produced in the following 10 months:December 2008, January-February 2009, October 2009, March-April 2010 and September-December 2010.Injector lines using this material exhibit a significantly higher failure rate.Dealers will replace injector line #2 in all vehicles built in these months.In addition, as a precautionary measure, all recalled vehicles will have vibration dampers installed on all four fuel injector lines.Analysis of NHTSA complaints, VW complaints, VW field reports and warranty claims found allegations of injector line leakage in 443 subject vehicles.The leaking line was not identified in 62 of the vehicles.For the 381 that did provide information about which injector lines were leaking and/or replaced, 358 (94%) involved an injector line #2 leak/repair.Almost three-quarters of the injector line #2 leak/repair incident vehicles were built in the 10 months identified by VW, which accounted for approximately one-quarter of the recalled vehicles.The failure rate for injector line #2 in vehicles built in the 10 months affected by the supplier line scratching issue is 6.0 incidents per thousand vehicles (IPTV).The failure rate for injector line #2 in other production months of recalled vehicles is 0.8 IPTV.The leak/repair rates for the other injector lines are all well under 1 IPTV.The action taken by Volkswagen is sufficient to resolve the issues raised by this investigation. The agency will continue to monitor this issue and reserves the right to take further action if warranted by the circumstances. Accordingly, this investigation is closed.

EA11003 · High-Pressure Fuel Pump Failure

Opened Feb 7, 2011 · Closed Mar 27, 2015

Status: closed (inferred from source dates) · Fuel System, Diesel; Fuel System, Other:delivery:fuel Pump

The Office of Defects Investgation (ODI) opened EA11-003 on February 7, 2011, based on 160 complaints to ODI and Volkswagen involving high pressure fuel pump (HPFP) failures in model year (MY) 2009 through 2010 Volkswagen Jetta and Golf and Audi A3 TDI vehicles and questions regarding fuel sample results provided by Volkswagen as part of its response to PE10-034.During EA11-003, ODI analyzed design information, field experience and test data for MY 2009 through 2012 Volkswagen Jetta, Golf and Touareg and Audi A3 and Q7 vehicles equipped with TDI engines. Volkswagen has not identified any design or manufacturing defects in the subject TDI Clean Diesel pumps and has stated that the subject pumps were designed, tested and approved for use in the United States market, with substantial design margins for fuels that are out of specification.Volkswagen believes that misfueling with gasoline is the primary cause of HPFP drivetrain failures in the field.Only the Q7 vehicles were built with misfuel protection devices.In May 2013 Volkswagen initiated a service campaign to install misfuel protection devices in all MY 2009 through 2012 Jetta, Golf and A3 vehicles.Volkswagen implemented misfuel protection devices in all of the subject models beginning in MY 2013. ODI?s analysis of HPFP drivetrain failure incidents indicates that most failures do not result in engine stall while driving and, when pump drivetrain failure does result in stall while driving, it is usually preceded by numerous warning symptoms (e.g., glow plug warning lamp, chime, limp mode, and driveability symptoms).The failure data for the subject vehicles show relatively low stalling rates (less than one percent at three years in service) for each of the pump designs used in the subject vehicles.There have been no reports of crashes, injuries or fatalities related to the alleged defect. Based on these facts, 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 continue to monitor complaints and other information relating to the alleged defect in the subject vehicles and take further action in the future if warranted.For additional information, see the closing report in the document file for EA11-003.

Volkswagen has not identified any design or manufacturing defects in the subject TDI Clean Diesel pumps and has stated that the subject pumps were designed, tested and approved for use in the United States market, with substantial design margins for fuels that are out of specification.Volkswagen believes that misfueling with gasoline is the primary cause of HPFP drivetrain failures in the field.Only the Q7 vehicles were built with misfuel protection devices.In May 2013 Volkswagen initiated a service campaign to install misfuel protection devices in all MY 2009 through 2012 Jetta, Golf and A3 vehicles.Volkswagen implemented misfuel protection devices in all of the subject models beginning in MY 2013. ODI?s analysis of HPFP drivetrain failure incidents indicates that most failures do not result in engine stall while driving and, when pump drivetrain failure does result in stall while driving, it is usually preceded by numerous warning symptoms (e.g., glow plug warning lamp, chime, limp mode, and driveability symptoms).The failure data for the subject vehicles show relatively low stalling rates (less than one percent at three years in service) for each of the pump designs used in the subject vehicles.There have been no reports of crashes, injuries or fatalities related to the alleged defect. Based on these facts, 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 continue to monitor complaints and other information relating to the alleged defect in the subject vehicles and take further action in the future if warranted.For additional information, see the closing report in the document file for EA11-003.

The Office of Defects Investigation (ODI) and Volkswagen (VW) have received a total of 160 complaints and field reports alleging incidents of engine stall and/or loss of power that appear to be related to high pressure fuel pump (HPFP) failures in certain model year (MY) 2009 through 2010 Volkswagen Jetta and MY 2010 Volkswagen Golf and Audi A3 vehicles equipped with TDI clean diesel engines.Approximately half of the reports indicate that the failure resulted in an engine stall incident, with many of these alleging stall incidents at highway speeds in traffic with no restart.There has been one minor crash alleged to have resulted from HPFP failure in the subject vehicles.In response to ODI's information request for PE10-034, VW indicated that it had found no defect related to motor vehicle safety with relation to the TDI Clean Diesel fuel system at issue in this investigation and attributed problems with HPFP failure to operation with gasoline contaminated diesel fuel.Volkswagen stated that even a small amount of gasoline in the diesel fuel may disrupt the necessary lubrication required and may cause the HPFP to fail.In response to concerns that fuel contamination was the major cause of HPFP and related fuel system failures, VW issued a Technical Service Bulletin in May 2010 (VW TB V011011 2023624 and Audi TB A011008 2023360-1), with instructions to inspect the diesel fuel for vehicles requiring fuel system service that have symptoms associated with HPFP failure.The bulletin states that fuel system damage incurred by use of fuel not complying to ASTM-D-975 Grade 2 S15 (B5 or less biodiesel content) standards will not be covered under warranty. Volkswagen also provided information about 121 mis-fueling incidents reportedly acknowledged by consumers or dealers and test results for about 50 diesel fuel samples taken from complaint vehicles in late-August through early-October 2010.The mis-fueling incidents include about 20 reports involving incorrect fueling by dealer sales or service personnel and generally report symptoms such as rough running, stalling and/or no start within a few miles of refueling the vehicle with gasoline.Volkswagen indicated that the testing of fuel samples from complaint vehicles found that nearly 90 percent contained high amounts of gasoline.Volkswagen implemented design changes for the HPFP in May 2008, September 2009 and November 2010 to improve the robustness of the pump when used with poor quality fuel.ODI analysis of HPFP failures identified from all sources shows failure rates of 0.53% for MY 2009 vehicles and 0.11% for MY 2010 vehicles.This investigation has been upgraded to an Engineering Analysis (EA11-003) to continue to investigate the issues with mis-fueling and HPFP design identified during the Preliminary Evaluation.
