I purchased my Jetta TDI Sedan brand new, the car pulled to the right severely, after months of letter writing phone calls, and endless visits to the servise dept, VW gave me another car. After 5,000 miles in the new car the steering wheel shakes severely. I have made numerous visits to the dealer with absolutely no help. VW of America was worse, I would never ever own another Volkswagen.
The good gas mileage.
I bought a 15 year old Honda Accord after this nightmare, it is 150% more reliable than the new cars I bought from Volkswgen. Drivers wanted, mechanics and engineers needed!
