Filed Aug 28, 2012 · Electrical, Fuel system · 104,000 miles · CA

We were driving on a two lane highway. The cruise control was set. Out of nowhere the car just quit. The gauges went to zero. The car didn't have power. We coasted until we found a clearing where we could pull off the road. We were able to apply the brakes to come to a complete stop. We were very lucky we were able to coast far enough to find a spot to pull off. There was not an emergency lane on the road. The closest town was 18 miles away. We put the car in park and tried to start it without any luck. After awhile it did turn back on and we were able to drive to the dealership.

First time occurred at approximately 42,150 miles. Car driving on highway in 6th gear with cruise control activated. Sudden loss of power and flashing check engine light, "engine fault workshop" displayed. Car can no longer reach highway speeds. Pulled over at next exit. Turned off car, checked under hood, no noticeable issues. Restarted car, no lights or warnings. Drives normal. Called dealer and brought in later the same day with 42,259 miles. They put it on the computer and found a tsb 2020606 for a software update. Drove vehicle out of dealer lot, got on highway approximately 5 miles from dealership in 6th gear around 70 MPH and same issue with flashing check engine light and loss of power. Immediately brought the car back to the dealership with the flashing check engine light still on. They brought into the shop and were unable to find any issue. Performed another software reflash. Had to pay $102.60 (one hour of labor, plus tax). This issue had been ongoing for months, through the summer with no resolution. Typically happens at highway speeds, but sometimes in 2nd or 3rd gear on local roads. Finally, in september with approximately 54k miles, car once again had issue on highway. This time, restarted, and a solid check engine light stayed on. Immediately called volkswagen of america hotline and explained my issue, stated it was a safety issue and I'm concerned. They gave me a case number and told me to call the dealer. Dealer was able to get my car in later that day, and was able to pull codes for fuel system issue. Dealer took a fuel sample, found shavings in fuel canister, and got authorization to perform warranty repairs of entire fuel system from vw. They said my car would be fine to drive for now. One month later at approximately 57k miles bringing car in. Car continues to have issue, and almost caused an accident from power loss. Very concerning problem.

On march 6, while driving a 2009 vw jetta tdi at approximate 70 MPH on the highway, the cruise control shut off, the glow plug light came on, and an warning that read "engine failure workshop!" came on. The car would not accelerate faster than 58 MPH and I pulled over to the side of the road. The owner's manual did not indicate the meaning of the glow plug warning light. I turned the car off and restarted it and both the glow plug light and "engine failure workshop!" lights were off. I drove the car home and called the dealership the next morning. The dealership service center indicated that the warning light indicated the glow plug. The dealership stated that I could continue to drive my car until a part they ordered for me came in unless I experienced "driveability" issues, at which time I could take it directly to the dealership.

Transmission spontaneously disengages while vehicle is moving. Problem sometimes fixes itself immediately, sometimes the vehicle needs to be restarted in order for the problem to be cleared. The dealership is aware of the problem, but is unwilling to fix it sitting that they cannot reproduce the circumstances surrounding the problems. The dealership will only examine the problem 24 hours before I incur charges for the loaner vehicle. So far no parts have been replaced, and no work has been done beyond attempts to reproduce the problem. This problem caused a near accident at highway speeds when it occurred while the engine cruise control was engaged. After disengaging power, the engine revved to red line, the transmission then re-engaged. This problem occurs frequently, up to 3 times per week.

1. Driving at highway speeds in 6th gear, flat road, in cruise control. No erratic driving or fast acceleration. 2. The automatic transmission fails by falsely shifting into neutral when the transmission shifter is in drive. The prnds gear indicator on the dash began flashing when this happened. This has occurred 5 times since I bought the car on july 15, 2009. The car lost all power to the front (drive) wheels and had to be stopped on the side of the highway, then restarted for the car to return to normal operation. 3. The car has been submitted to the vw dealer's service dept. No parts have been replaced or repaired.
