2015 Volkswagen Passat Fuel System Problems

The contact owns a 2015 Volkswagen Passat. The contact stated that fuel was leaking from the vehicle. There were no warning lights illuminated. The vehicle was taken to the local dealer, but the vehicle was not diagnosed or repaired. The vehicle was taken to another local dealer, East Dallas Volkswagen (12635 Lyndon B. Johnson Fwy., Garland, TX 75041); where it was diagnosed that the fuel pump was leaking fuel and that the gasket and fuel pump needed to be replaced. The vehicle was not repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 120,000.

Looks like the plastic the fuel pump housing is made out of is low quality or prone to degradation by fuel. Hairline cracks have formed on the fuel pump housing causing fuel to leak when the pump is pressurized and running. In my case a pin hole also appeared causing the leak to be quite significant. When reviewing the attached image. Most the major looking hairline cracks seep fuel. The pin hole can’t really be seen in that image but is located in the middle of the raised lettering that starts with a “C” (in between M and E) (I have a video of it)

The contact owns a 2015 Volkswagen Passat. The contact stated that while driving at various speeds, the vehicle sputtered intermittently. The vehicle was taken to the dealer, who diagnosed the vehicle and determined that fuel was leaking into the engine compartment, causing engine failure. The contact stated that the dealer had repaired the vehicle and possibly cleaned the engine. The dealer had informed the contact that the engine would last 4-6 months before complete engine failure. The vehicle was returned to the contact; however, while driving approximately 35 MPH, the vehicle sputtered and then lost power. The vehicle was restarted after several attempts to continue driving. The vehicle was returned to the dealer but was not repaired. The dealer suggested that a new vehicle be purchased. The contact searched online and became aware of NHTSA Campaign Number: 15V028000 (Fuel System, Gasoline); however, the VIN was not included. The manufacturer was made aware of the failure and confirmed that the VIN was not included in the recall. The failure mileage was unknown.

TL* THE CONTACT OWNS A 2015 VOLKSWAGEN PASSAT. THE CONTACT STATED WHILE DRIVING AT 45 MPH, THE VEHICLE STALLED WITH THE CHECK ENGINE WARNING LIGHT ALONG WITH SEVERAL OTHER UNKNOWN WARNING LIGHTS. THE VEHICLE WAS TAKEN TO VALLEY AUTO WORLD VOLKSWAGEN (3810 SYCAMORE DAIRY RD, FAYETTEVILLE, NC 28303) WHERE THE VEHICLE WAS DIAGNOSED WITH A FUEL PUMP FAILURE. THE VEHICLE WAS REPAIRED HOWEVER, THE FAILURE RECURRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 91,344.

ON TWO OCCASIONS, THE VEHICLE'S ENGINE STOPPED WORKING WHILE THE CAR WAS MOVING. THE FIRST INSTANCE, THE CAR STALLED WHILE MOVING AT 5MPH ON AN EXPRESSWAY EXIT RAMP. IT RESTARTED AFTER 30 MINUTES (BLOCKING TRAFFIC FOR THAT PERIOD OF TIME). WHEN ATTEMPTING TO RESTART, THE MOTOR WOULD TURN OVER, BUT THE ENGINE WOULD NOT START - AS IF THERE WAS NO GASOLINE. THE SECOND STALL OCCURRED WHILE DRIVING ON AN EXPRESSWAY AT 55MPH. IN THAT CASE THERE WAS AGAIN A SUDDEN LOSS OF ALL POWER. HOWEVER, THE VEHICLE WOULD NOT RESTART. THE CAR WAS TAKEN TO A DEALER ON BOTH OCCASIONS. THE DEALER REPLACED THE BATTER ON THE FIRST VISIT. ON THE SECOND VISIT, THE DEALER CLAIMED THAT THERE WERE FAULT CODES RELATED TO THE HIGH PRESSURE FUEL RAIL THAT NEEDED TO BE RESET.

ENGINE FAILURE DUE TO FUEL SYSTEM FAILURE. DURING DRIVING COMPLETE ENGINE SHUTDOWN. WILL NOT RESTART, VEHICLE TOWED TO DEALERSHIP. THIS HAPPENED A SECOND TIME WITHIN 2000 MILES. DEALER STATES CONTAMINATED FUEL BOTH INSTANCES. FUEL WAS PURCHASED AT TWO SEPARATE GAS STATIONS EACH TIME. COSTING 7000 DOLLARS IN REPAIRS FOR EACH INSTANCE.

I PURCHASED A VOLKSWAGEN PASSAT DIESEL AND DECIDED TO KEEP IT EVEN AFTER THE WHOLE DIESEL SCANDAL. TWO MONTHS AFTER THE SECOND PART OF THE "FIX" MY CHECK ENGINE LIGHT COMES ON SO I DECIDED TO TAKE IT TO THE DEALERSHIP BECAUSE MY WARRANTY WAS EXTENDED THROUGH THE WHOLE DIESEL LAWSUIT. I WAS TOLD THAT MY HIGH PRESSURE FUEL PUMP FAILED BECAUSE OF BAD DIESEL. I ASKED THE SERVICE CENTER HOW THEY DETERMINED MY BAD DIESEL WAS TESTED AND THEY DEMONSTRATED A VW APPROVED SPECIAL TOOL WITH A BOX THAT HAD A SMILEY FACE AND FROWN FACE EMOJI. THE REPAIR FACILITY ADVISED ME THAT THEY COULD'T PERFORM THE REPAIRS UNDER WARRANTY BECAUSE OF THE POOR QUALITY OF THE DIESEL. I CALLED VOLKSWAGEN OF AMERICA AND GOT THE RUN AROUND. I HAD TO USE MY VEHICLE'S CAR INSURANCE TO COVER THE $7400 REPAIR BILL. AS A TEN YEAR VETERAN VOLKSWAGEN/AUDI TECHNICIAN I/WE ARE WELL AWARE OF THE DESIGN FLAW OF THIS HIGH PRESSURE FUEL PUMP. THE PUMP FAILS AND SENDS METAL FRAGMENTS THROUGHOUT THE ENTIRE FUEL SYSTEM ALL THE WAY BACK TO THE FUEL TANK. I WOULD BE OK REPLACING A $800 HIGH PRESSURE FUEL PUMP BUT THIS DESIGN ALLOWS THE METAL FROM THE HIGH PRESSURE FUEL PUMP WHICH IS DRIVEN BY THE TIMING BELT TO RECIRCULATE BACK INTO THE TANK AND FURTHER CONTAMINATE THE ENTIRE SYSTEM AND NOT TO MENTION THE FOUR FUEL INJECTORS AT $500 A PIECE (TIMES FOUR). I CALLED THE VOLKSWAGEN DIESEL SETTLEMENT LINE AND EXPLAINED MY FRUSTRATION AND EVEN MADE THE PERSON WHO ANSWERED THE PHONE LAUGH WITH THE WHOLE SMILEY FACE AND FROWN FACE TESTER. I AM A FACTORY TRAINED TECHNICIAN AND EVEN I DON'T UNDERSTAND THE LOGIC BEHIND THIS, GIVE ME PERCENTAGES AND TOLERANCES WHICH I CAN UNDERSTAND. UNFORTUNATELY THIS WILL BE MY LAST VOLKSWAGEN I WILL EVER PURCHASE I KNOW THIS DOESN'T MATTER MUCH TO VW BUT I WILL BE DEFINITELY SPREADING THE WORD.

VEHICLE LOST POWER AND STOPPED. WOULD NOT RESTART. MILLER OIL CO. TESTED FUEL IN TANK WITH NO ISSUE. VW OF AMERICA TESTED FUEL IN CAR AND FOUND LUBRICITY WEAR DIAMETER SCARING OF 557 MICRO METERS 37 MICRO METERS OUT OF SPEC. $10K TO REPLACE FUEL SYSTEM.

TL* THE CONTACT OWNS A 2015 VOLKSWAGEN PASSAT. WHILE DRIVING AT APPROXIMATELY 70 MPH, THE FUEL GAUGE PROVIDED INACCURATE READING LEVELS. THE FAILURE RECURRED NUMEROUS TIMES. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE VIN WAS NOT PROVIDED. THE APPROXIMATE FAILURE MILEAGE WAS 6,000.
