A fuel leak has developed from the top side of the fuel tank on the drivers side of me vehicle. A fuel leak in this manner is a serious critical and immediate safety risk. Recall 08V156000 was 'performed' on my vehicle back in 2008 but the exact same fuel system safety defect has returned. VW acknowledges the recall and claims it was completed while only an inspection to check for fuel leaks was performed at the time. VW Care and my local dealership refuse to address the ongoing issue. This poses a continued fire risk, and I am now being told to pay out of pocket for a known safety recall that clearly failed to remedy the original defect.

There was a recall reported by the manufacturer, Volkswagenm in 2008. There were multiple Fuel System issues: A Heat Shield that may contact the exhaust system and result in a vehicle fire; a fuel leak from a fuel line or fuel tank ventilation valve, in the presence of an ignition source, can lead to a vehicle fire. In 2008, my car was inspected and the recall was deemed "complete." However, the car was only 4 years old at the time and no repairs were made. Only a visual inspection was done. I bought the car used 6 years ago, and it has been diagnosed as having a defective fuel tank ventilation valve. VW should pay for the parts and labor to have this fixed because it was never fixed. I've been told there's no statue of limitations on recalls. VW claims that because the recall was deemed "Complete" that they "fixed" the issue but they didn't.

When you fill up the fuel tank it leaks it leaks a quarter of a tank of fuel roughly 4 to 5 gallons of fuel drip out there's a factory recall on this issue I took it to the volkswagen dealer paid money to have them inspect it and they said yes it's leaking at the factory recall I've had an independent dealer confirm that! Volkswagen will not do anything due to what they claim a remedy was done by moving fuel lines 10 years ago, obviously it was not or I would not have 4 gallons of fuel spill in my driveway vehicle is basically in operable and they want $3000 to put a new fuel tank in when it's a factory recall which never expires I have talk to the volkswagen rep and the only thing I have found in forums is do you have to go to volts wagon of america and fight them and this is ridiculous when they know they have an issue!! To drive this vehicle we never fill it over a half a tank of fuel so we do not leak fuel or explode while we're driving hopefully please help in anyway you can thank you

2004 volkswagen passat 4motion, the fuel tank rollover/vent valve on the top of the tank has cracked and is leaking gasoline onto the exhaust system. The tank was filled up on 2/22/2015 and started leaking large amounts of fuel from the top of the tank over the exhaust. This continued until the tank reached 3/4 full. If the fuel tank is filled above 3/4 it will leak fuel until it gets to 3/4. If the vehicle is parked with the front downhill, it continues to leak beyond the 3/4 point. This failure was part of a previous vw 2008 the federal safety agency mandated recall 08v156000, but only required dealer inspection of the rollover/vent valve and not replacement of the fuel tank with a functional part, if it was not leaking when inspected then do nothing. The rollover/vent is integral to the vw passat awd tank, and the complete fuel tank has to be replaced. Vw claim as the car was inspected in 2008, they are not responsible for the subsequent failure of the rollover/vent valve.

Fuel began leaking from the top of the fuel tank after fill up. My daughter was heading back to college, and as she pulled away I noticed a large puddle of gasoline in the street. The federal safety agency had previously recalled the vehicle in 2008 (26e5/r5) action number (pe08008). Vw dealer inspected and installed heat shield. No fuel leak at this time. In september 2012 fuel tank began leaking, vw dealer replaced the fuel tank, washer, gasket and clamp under the recall. In september 2014 I brought car back to vw dealer, and they said they are only responsible to fix the car once. Fed up with vw, I brought car to my local mechanic, and upon inspection he found the nipples on the fuel tank rollover valve were again cracked. I had him replace the tank. Obviously vw didn't properly fix the problem, and or replaced the tank with the same defective design and the tank cracked again. This is a very serious safety issue, and I feel that vw should pay for this repair. If it was done right and corrected, the tank would not be leaking again after less than 2 years, and 20,000 miles. This could have caused a fire with my daughter in the car, and that is very upsetting to me.
