Owner reports
Selected complaints filed with NHTSA by 2005 Volkswagen Passat owners, lightly cleaned up (personal details are redacted by NHTSA).
Approximately back in June 2021, I noticed the smell of diesel fuel coming from the rear of the vehicle, noticed hours and days after the vehicle was parked. The smell is partially present from the interior in the trunk area, but mostly evident when standing near the vicinity of the fuel tank when outside of the vehicle. After driving the vehicle, I occasionally notice small puddles of diesel fuel (as evidenced by the oily texture and smell) coming from below the fuel tank. On occasion, I can also spot actual drops of diesel fuel on the lower car frame from underneath the vicinity of the fuel pump. These puddles usually evaporate or dissipate within an hour or two after appearing. Given that these puddles only appear after driving, and not after extended periods of the vehicle sitting in my driveway, I suspect that there is a leak in the fuel pump. …
I completely filled the fuel tank of my car in the morning on 4/22/2019. I then drove home and parked the car in my driveway (so it was stationary at this time). That afternoon I smelled a strong odor of gasoline and saw a puddle on the ground underneath the car by the driver's side rear wheel. I thought that maybe I overfilled the fuel tank so I waited to see if the issue would go away after I drove a bit. On 4/23/2019 I still smelled gasoline and saw a puddle under the car after parking. I determined the fuel was only leaking while the car was in motion and it became apparent there was a larger issue. On 4/24/2019 I took the car to a mechanic to diagnosis where the leak was coming from. The mechanic could smell gas and found fuel residue, but nothing fresh. It was recommended that I fill the fuel tank and return to see if a leak could be found. …

Within seconds, the vehicle caught fire. The contact managed to safely exit the vehicle. The manufacturer offered him a settlement of $2,700 because the vehicle was not adequately repaired according to NHTSA campaign id number 08V156000 (fuel system, gasoline: delivery).

This is the 4 th time I have had the check engine light come on along with misfire issues. Each time costing me at least 2000.00 to correct only for a short time. Have changed oil pump, plugs, injectors just to name a few. I love my car but this has been a money pit from day one. Vw needs to be held responsible for these issues. Oil sludge, is a big problem too. I just had the timing belt replaced with injectors and a new gasket set up and ran good for two months and now I'm back in the same position of needing the same repairs once again. Car was driving began to shutter trying to stall. Help!

My 2005 Passat has developed a fuel leak under the tank. My vehicle looks like new and only has 72000 miles on it. This leak/smell occurs after when the car is moving as well as when the car is sitting in the driveway. Seems very dangerous to me and I've read many complaints describing this exact scenario. Why is vw not forced to recall and inspect for this situation.
2005 vw Passat wagon, 4 motion, 128,000 miles, w/ intense odor of gas in the cabin of the car; after driving 15 miles to work, I developed a headache and illness symptoms which lasted for 2 -3 days. Car was towed to local vw dealer. I contacted vw of America, who agreed to diagnostics. Large fuel tank fracture confirmed. After many discussions with customer service at vw of America, they refused to cover repairs, though they did confirm that this failure was the same failure which had LED to a previous recall campaign of the fuel tank/system, but since my car had already been repaired (2015) w/ a superseded part and it was past the 12 month warranty period, I did not qualify, nor would they offer goodwill service. They did acknowledge, however, that it was a serious safety issue and the car should not be driven. …
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. …
