While driving 60 MPH on highway 95 in needles california the glow plug light came on and began to flash. Cruise control disabled and the speed of the vehicle began to decrease. No power could be felt when pressing the accelerator pedal and the engine RPM began to fall. Vehicle was placed into neutral and coasted to side of the road. After complete shutdown the vehicle would not restart, unable to drive. Had vehicle towed by aaa to the nearest vw dealer in henderson nevada and problem was diagnosed as high pressure fuel pump failure (hpfp). Fuel pump was damaged and metal debris from the pump was sent into the fuel delivery system and returned to the fuel tank. All fuel related parts will require replacement and/or cleaning to remove debris. The vehicle required parts that took approx 3 days to obtain and additional days to complete the repair.

On my way home from work I was cruising down at the interstate with the car on cruise control. Everything was fine the first 45 minutes of driving then all of a sudden my glowplug light illuminated and started flashing meaning engine malfunction. My vehicle started losing speed all of a sudden on the interstate which could have easily caused a crash. Luckily I pulled the vehicle over on the side of the road and the vehicle just stalled out on me. Now volkswagen is saying the high pressure fuel pump sent metal shards into the fuel system and it all needs replaced and they will charge me 8000 dollars. I cannot be blamed for the failure of a fuel pump on a car with 40000 miles.I never allow the tank to go below 1/4 of a tank. There have multiple reports of peoples high pressure fuel pump going out and sending metal shards into the fuel system. This is very dangerous and could get someone very hurt or could possibly result in death. Something needs to be done about this.

While driving on the highway with cruise control engaged at/around speed limit, I noticed the rpms jumping and could feel the car jerking, as if some kind of acceleration/deceleration was happening. I also notice rpms jump 50 up/down while idling. This seems to happen when driving down hills on cruise control, more prevalent in colder weather. No loss of control has occurred, but appears to be issue that is slowly worsening.

Unexpected acceleration on cruise control. When the cruise control is set, pressing the 'coast/decelerate' button several times causes the cruise control unit to jump by several MPH, I.e. Accelerate. Example: cruise is set at 55 MPH. Press the coast button three or four times (car should decelerate by 1 MPH for each press of the button), the cruise speed will set at a higher speed, such as 58 MPH. This can be observed by looking at the display which shows the speed at which the cruise control is set, as well as the acceleration of the car. This behavior can be easily replicated and demonstrated, though it does not occur every time. This has been observed for the past several months.
