I DECIDED TO CHANGE THE OIL MYSELF IN MY CAR, SINCE I WANTED TO SAVE MONEY AND I KNEW WHAT I WAS DOING. INSTEAD OF DRAINING THE OIL, I ACCIDENTALLY DRAINED THE TRANSMISSION FLUID. I DIDN'T FIGURE OUT THAT IT WAS TRANSMISSION FLUID BECAUSE IT LOOKED LIKE OIL! SO, THIS IS WHAT HAPPENED AFTER; I DROVE HOME (NOT KNOWING THERE WAS NO TRANNY FLUID IN IT) AND I NOTICED THAT THE CAR WANTED TO TAKE OFF BY ITSELF. IT KEPT DOING TIS TWO OR THREE MORE TIMES WHEN IT BECAME STUCK IN 4TH GEAR. I MANAGED TO SAFELY GET HOME, AND FIGURED OUT WHAT HAPPENED. I AM REPORTING THIS BECAUSE THIS IS A DESIGN FLAW!!! THE TRANSMISSION FLUID DRAIN HOLE IS WHERE THE ENGINE OIL DRAIN HOLE SHOULD BE! LUCKILY, AFTER I PUT FRESH TRANNY FLUID IN IT, THE CAR WAS FINE. I WONDER HOW MANY OTHER PEOPLE THIS HAPPENED TO.

ON 3/23/13, WHEN TURNING LEFT IN TRAFFIC, THE "SEALED FOR LIFE" 5-SPD AUTO TRANSMISSION MADE AN INCREDIBLY HARD SHIFT, BEGAN SLIPPING BADLY, AND QUICKLY LOST 3 FWD SPEEDS, "LIMPING" IN FOR SERVICE. NORMALLY, A TRANS FAILURE AT 143K WOULD NOT PROMPT AN NHTSA COMPLAINT. IT IS NOT THE CAR, BUT RATHER VWOA AND ITS DEALER NETWORK, THAT ARE THE PROBLEM. MY LOCAL DEALER REFUSED TO CHECK AUTO TRANS FLUID LEVEL, AND WOULD ONLY GRUDGINGLY DO A FLUID CHANGE IF I WANTED, FOR AN EXTORTIONATE $700, STEADFASTLY MAINTAINING THAT NEITHER WAS NECESSARY. VWOA TODAY 4/5/13, IRONICALLY, CRITICIZED ME FOR NOT FOLLOWING THE OWNER'S MANUAL RECOMMENDATION OF CHECKING FLUID EVERY 40K MILES. LOCAL DEALER WANTED OVER $4400 + MISC FEES & TAX TO REPLACE THE TRANS. AT THE SAME TIME, THEY INDICATED MY NEW TIRES WITH 500 MILES ON THEM WERE IN A MARGINAL TREAD WEAR CONDITION. DITTO THE RECENTLY RENEWED (AT THE SAME DEALER!) REAR BRAKES. BTW, THE TRANSMISSION MANUFACTURER, ZF, RECOMMENDS COMMUNICATING TO CUSTOMERS THE BENEFITS OF FLUID CHANGES AT 50K MILE INTERVALS. VW WON'T LISTEN TO EITHER CUSTOMER OR TRANS MFR. TRANS WAS REBUILT AT QUALIFIED INDEPENDENT SHOP. THERE WAS ALSO AN EARLIER RECALL (THANKS, NHTSA!) OF CERAMIC GLOW PLUGS THAT WOULD FALL INTO CYLINDERS AND CAUSE CATASTROPHIC DAMAGE. FORTUNATELY, I HAD THE REPAIR DONE INDEPENDENTLY, AS THIS CONDITION WAS KNOWN FOR AT LEAST 2 YRS BEFORE VW'S OFFICIAL RESPONSE. VW DID COMPENSATE ME FOR THIS, BUT I WONDER HOW MANY $9K ENGINES WERE DESTROYED WHILE VW CONTEMPLATED ITS COLLECTIVE NAVEL. BTW, AFTER THE OFFICIAL VW FIX (DONE AT DEALER), THE CAR STARTS IN WINTER LIKE A 1980 RABBIT DIESEL. I FITTED A ZEROSTART AS CORRECTIVE MEASURE. VW ALSO REFUSES TO DISCUSS THE BALANCE SHAFT CHAIN DRIVE ISSUE WITH ME. A TICKING TIME BOMB AT 143K. THEY KNOW IT. I KNOW IT. NHTSA, PLEASE TAKE VWOA TO TASK! AS FOR ME, I'M NOW SHOPPING COMPETITORS. *TR

VOLKSWAGEN PASSAT PASSENGER VEHICLE MODEL YEAR 2004 AND 2005 WITH 2.0L DIESEL TDI ENGINE. BALANCE SHAFT AND OIL PUMP ARE DRIVEN WITH A CHAIN MECHANISM WHICH HAS A HISTORY OF FAILURE WITH LESS THAN 100,000 MILES USAGE. THIS PROMPTED A DESIGN CHANGE AND A RECALL OF AFFECTED VEHICLES IN EUROPE. NO RECALL IN NORTH AMERICA. RECALLED VEHICLES IN OTHER AREAS OF THE WORLD WERE RETROFIT WITH A GEAR DRIVE MECHANISM THAT IS RELIABLE. FAILURE OCCURS WITHOUT WARNING AND WILL RESULT IN IMMEDIATE LOSS OF OIL PRESSURE AND RAPID ENGINE DAMAGE INCLUDING POSSIBLY ENGINE SEIZURE. IF THIS WERE TO OCCUR AT HIGHWAY SPEEDS IT WOULD BE A CLEAR SAFETY HAZARD. *TR

THE FAILURE IS WITH (1) THE BALANCE SHAFT OIL PUMP CHAIN DRIVE SYSTEM ON THE VW PASSAT 2.0 TDI DIESEL AUTOMOBILE. THE FAILURE HAS OCCURRED NUMEROUS TIME TO OTHER VW OWNERS AND PRESENT AN IMMINENT THREAT TO VEHICLE SAFETY SHOULD SUCH FAILURE OCCUR IN HEAVY TRAFFIC. (2) CERAMIC GLOW PLUGS FOR THE TDI DIESEL ENGINE HAVE A TENDENCY TO BREAK OFF AND CAUSE CATASTROPHIC DAMAGE TO A RUNNING ENGINE. BOTH DEFECTS HAVE BEEN RECOGNIZED BY VWOA AS EVIDENCED BY UPGRADES MADE TO THEIR EUROPEAN CUSTOMERS. HOWEVER VWOA IS TOTALLY IGNORING THE AMERICAN CUSTOMERS AND RESULTING IN EXORBITANT REPAIR PRICES. VW CONTINUES TO VIOLATE EPA RULE BY NOT RELEASING ECU REFLASH DATA TO NON VW SERVICE FACILITIES, HERE AGAIN CAPITALIZING ON A KNOWN DESIGN FLAW. LET IT BE KNOW THAT ONLY THE SYMPTOMS OF THESE IMPENDING FAILURES HAVE OCCURRED AT THIS POINT IN TIME. JUDGING FROM REPORTS OF OTHERS WHO HAVE SUFFERED ALREADY THIS VEHICLE IS IN IMMANENT DANGER. *TR

EVENTUAL FAILURE OF CHAIN DRIVEN OIL PUMP AND BALANCE SHAFTS, RESULTING IN A SUDDEN LOSS OF POWER AND DESTRUCTION OF THE ENGINE, LEADING TO A POTENTIAL LIFE/SAFETY SITUATION IN THIS 2005 PASSAT TDI. THIS METHOD OF DRIVING THE OIL PUMP AND BALANCE SHAFTS IS A VOLKSWAGEN ACKNOWLEDGED ENGINEERING FLAW AS NOTED IN TECHNICAL PRODUCT INFORMATION BULLETIN 2016429/2. NOT WISHING TO REPLACE AN ENGINE THAT AS A RESULT OF SAID FAILURE, MIGHT POTENTIALLY PLACE MYSELF AND PASSENGERS IN A LIFE THREATENING SITUATION, I HAVE PROACTIVELY CHANGED OUT THE CHAIN-DRIVEN OIL PUMP/BALANCE SHAFT MODULE FOR A GEAR DRIVEN ASSEMBLY AT A COST TO MYSELF OF $3000. I BELIEVE VW NEEDS TO STEP UP AND ISSUE A RECALL FOR THIS MODEL. *TR

I CURRENTLY LEASE A 2005 VW PASSAT. WARRANTY OFFERED: 5 YR/ 50,000 MILE. APPROX. NOV 7, 2008 VEHICLE DASHBOARD BEGAN TO REGISTER "STOP OIL PRESS LOW". IMMEDIATELY PULLED INTO CLOSEST GAS STATION AND PURCHASED A SYNTHETIC OIL FOR VW THINKING THIS WOULD SOLVE THE PROBLEM. ON NOV 17, 2008 DASHBOARD LIT UP AGAIN WITH SAME MESSAGE AND IMMEDIATELY BROUGHT VEHICLE INTO VISTA VW, POMPANO BCH, FLORIDA. WAS INSTRUCTED THAT ISSUE WAS POSSIBLY DUE TO FAULTY OIL PRESSURE DIP STICK CYLINDER AND NEED OF OIL CHANGE. (CYLINDER REPLACED AND OIL CHANGE COMPLETED) PRIOR OIL CHANGE WAS COMPLETED AT VISTA VW POMPANO BEACH. VW MECHANIC PLACED A CLEAR OIL CHANGE MAINT. STICKER WITH INCORRECT MILEAGE DUE AT NEXT OIL CHANGE. OIL CHANGE SHOULD HAVE OCCURRED AT 38,000 MILES VS. 45,000. VISTA VW STATED I WOULD NEED TO PAY FOR A DIAGNOSTIC TEST TO BE COMPLETED (APPROX $166.00) AS WELL AS AN HOURLY CHARGE FOR LABOR (APPROX. $110 P/HR) NOT INCLUDING ANY AND ALL REPAIR TO BE PAID FOR UPON COMPLETION. THIS DUE TO WARRANTY EXPIRED. BROUGHT VEHICLE IN AT 792 MILES OVER 50,000. DUE TO THE EXPENSE THAT I WOULD HAVE INCURRED IT WAS NOT FEASIBLE FOR ME TO GO AHEAD AND PERFORM THIS DIAGNOSTIC TEST HENCE CAUSING ME TO LEAVE NO FURTHER CHOICE BUT TO DECLINE SERVICE. I ATTEMPTED TO TRADE MY PASSAT IN EARLY AND RELEASE A NEW VEHICLE AND WAS UNSUCCESSFUL IN DOING SO. APPROXIMATELY 1 MONTH LATER I WAS AT GUNTHER VW COCONUT CREEK AND INFORMED FINANCE MGR THAT I NOW HAVE AN ENGINE LIGHT ON. I WAS TOLD TO TRY AND DRIVE THE VEHICLE BACK HOME AND SEE IF THE LIGHT GOES OUT. THAT MAYBE IT'S A FAULTY SENSOR. UPON ARRIVAL AT MY RESIDENCE THE VEHICLE COMPLETELY SHUT DOWN AND ENGINE FAILED. THE FOLLOWING DAY I HAD THE VEHICLE TOWED TO A MECHANIC. MY MECHANIC STATED THAT THE APPROX. COST FOR REPAIR WOULD BE ANYWHERE BETWEEN $8,000 - $10,000. I IMMEDIATELY BEGAN RESEARCH AND FOUND THERE IS A LAWSUIT FROM THE CONSUMERS OF VW PASSATS IN REGARD TO THIS EXACT SAME MECHANICAL ISSUE & VW WILL NOT COMPLY WITH THIS ISSUE. *TR

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.
