Persistent diesel exhaust leak which interferes with my breathing in the cabin. The vehicle has been back to the napleton VW sanford/orlando dealer 5 times and they fix something different each time with no improvement. Now they want me to pay for 5th repair even though issue was brought to their attention initially in warranty period.

While traveling approximately 55 mph on a highway the vehicle suddenly lost power/turned off. There were no warning lights, no noises, no vibrations, no signs of anything. Vehicle stalled at freeway speed and it had to be towed to VW dealer where I was informed that the high pressure fuel pump (hpfp) had failed. There was no sign of mis-fueling (no gas in tank when tested), contaminants are unknown. It seems that the hpfp is not designed to perform within the tolerances necessary to operate safely and reliably on 'pump fuel' available to consumers; it is mechanically defective and clear and present danger to highway safety. Request engineering analysis.

I purchased this vehicle 3 days prior as a "certified pre-owned" from lakeland VW of Florida. I was approaching an intersection and preparing to stop. As I rolled up and went to turn right, the vehicle suddenly lost power. Several attempts to restart were unsuccessful. We had to push the vehicle across a busy street, at which point I called roadside for a tow. The VW dealer told me today that it is my high pressure fuel pump, which seems to be a common failure for this vehicle.

High pressure fuel pump ("hpfp") failure resulted in an engine stall incident, at highway speeds in traffic with no restart, contributing to an accident.

On Wednesday January 22, 2014 I was driving West on us route 9 in barrington nh at approximately 11am in my Volkswagen Touareg 2010 tdi. There was nothing unusual about the performance of the car before I felt a strange lag and then a warning light started flashing to stop the car. Before I could pull off the road the car lost power and died. Since the warning to stop the car came up I did not try to restart the car. I sat on the side of the road bewildered for a moment as I'd only purchased this car 3 weeks before and it was only a few miles short of 30,000 miles on the odometer. Being stranded partially in the middle of the road was terrifying as I was in a 50mph zone and people were flying past me upwards of 60mph while my car was barely straddling the white line. Also, it was 8 degrees outside and there was no place for me to wait safely outside of the car due to considerable frozen snow banks flanking the roadway. My options were to pray not to get hit or risk freezing while waiting for a tow truck. Overall this was a terrifying experience to have in a new car who's supposed toughness and reliability was one of its selling points. The dealer (quirk VW in manchester, nh) has told us that the fuel was contaminated leading to a hpfp failure which my husband says this same vehicle has had replaced less than 8,000 miles ago under the previous owner. He also said that I should mention that this is the same hpfp made by Bosch as the golf, jetta and A3 which has been investigated under EA11003 for failure.

While traveling approximately 75 mph on an interstate the vehicle suddenly lost power/turned off. There were no warning lights, no noises, no vibrations, no signs of anything. Vehicle had to be towed to VW dealer where I was informed that the high pressure fuel pump had failed allegedly due to substandard/contaminated diesel fuel. There was no sign of mis-fueling (no gas in tank when tested), contaminants are unknown. It seems that the hpfp is not designed to perform within the tolerances necessary to operate safely and reliably on 'pump fuel' available to consumers.
