After going to the mechanics after the check engine light came on, I was expecting all the problems to be gone but to my surprise the jolting when I accelerate is still there. Its a very harsh jolt forward roughly when its going to second gear, the rpms go to 4k then jump down to 2k and it does that for a while. For example I'll be driving and then all of a sudden it'll do a harsh jolt forward and will continue to do that when accelerating or when attempting to go at a steady speed. Another problem is the seatbelts are not retractable anymore and I have no idea why. When I would turn off the car the gas would be regurgitated back as if the car was on as it's completely off. I don't know where it comes from but water gets in the car when it rains and the carpets will be completely soaked and it'll smell like mold, we have tried to fix it and mechanics have looked at it and they are clueless too.
The vehicle hesitates when taking off from a stop. I feel this is unsafe because the danger of being hit if you pull out in front of another vehicle and the car hesitates. It appears that all of 2007 vw autos do this. I met with a repair manager from boardwalk vw and a rep from vw of America. I was told that there is nothing to repair that this is normal. 3 of 4 vehicles I draw do it. I also road in another vehicle at the dealership and could feel it while the vw rep drove it. I could see his body move as it did it and he denied. I bought the vehicle for my twin daughters that turn 16 in October. The vehicle is unsafe and really unsafe for inexperienced drivers. The vehicle was bought new about 2 months ago.
