Car stalls at highway speeds when at quarter tank or less. Parts replaced, still occurs. There is no known fix for this problem, it always comes back, and is most likely a manufacturers defect with the fuel pump system that is being ignored by vw of America. This is happening to hundreds and most likely thousands of Volkswagen Jetta, golf, beetle and gti owners. We have been connecting the dots through online vw forums and are frustrated! there have been accidents reported due to sudden power loss and therefore deceleration due to this issue. Just this morning my Jetta stalled in front of a semi truck doing 65mph on the highway. This is a very dangerous problem, it's happening to a lot of owners of vw's manufactured between 1999 and 2005, and it needs your attention before someone gets seriously injured. Thank you.
