What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
After being parked and turned off the windows roll. Down the alarm is disabled, the doors unlock. While driving lights go. On and off doors lock and unlock emergency flashers go off and alarm will go off. Can't unlock car without setting alarm off.
Airbag warning lights came on with a statement about faulty airbag ... Epc warning lights came on first when vehicle was in motion. Vehcle was stopped. On re-start, air bag warning lights came on. Vehicle was iddling and stationary.
I find this response inadequate and, in light of reading many other posts describing similar or identical problems with the supposedly repaired fuel leak, believe that volkswagen needs to be held responsible by nhtsa for correcting a recurring, dangerous safety issue.
Approximately two years ago I left my parents' house in this vehicle and immediately noticed a strong smell of gasoline. I pulled over and turned the engine off, and quickly found that fuel was leaking from the rigid line where it is fastened to the firewall in the engine compartment.
Purchased car used. First time I filled the gas tank strong smell of raw gas was present during the next several miles of travel. When I came out of the store from paying for the second fill up there was a big puddle of raw fuel all over the ground directly under the car.
Front disc brake rotor failed (separated from bolting hub) in hard braking at about 35 miles per hour. Brakes had been replaced in 2009 and had approximately 37,000 miles driven since replacement. No other signs of excessive wear or warpage noted by auto technicians. Failed part number 4b0-615-301-b.
