Two problems related to car stall have been reported for the 2009 Volkswagen Jetta Sportwagen. The most recently reported issues are listed below.
Was driving on residential street, approximately 25-30 mph, and car just lost power and stalled. After a few minutes it could start again - but the vehicle would not move, even if gas was pushed down. After a week at the dealership - they said it was the throttle. My car would not start before (after only having the car for approximately 7 months and approximately 2000 miles) - and after having it towed to the dealer, they just said the fuel was gelling. But they did do a computer upgrade and said there "particles in the fuel line" that they cleaned out and said I may have gotten "bad fuel". 1 week after my 40000 mile routine maintenance check - my glow plug light went on and I had to have a sensor replaced.
My 2009 jetta sportswagon tdi has stalled several occasions rounding corners as I downshift from a higher gear to a lower gear. I generally run the vehicle around 1700-1800 rpm and as I make the turn around the corner to slow down I am in the process of downshifting and the car stalls out while the clutch is engaged. This has happened randomly 4 times to me. The first time I thought I might have accidentally shift into a higher gear and stalled the engine, but since it has repeatedly happened and since I have owned a standard transmission vehicle since 1986, and have been driving standard vehicles since 1980 I have to question that it is something else besides my ability to drive.
