general problems of the 2010 Volkswagen Passat

There is a gas leak by rear tire. The mechanics that changed my tires said it was water. Went for an oil change, and they refused to do it because it's a gas leak. They can't tell where it's coming from.

Volkswagen dealer refuses to fix recalls.

I purchased 2010 vw Passat in June 2010. The car started to jump on acceleration from stop, auto hold button did not work, and car was rolling back on mild slope. I took car to the vw dealership. I was told that it is not safe to drive the car. I had to wait for 2 weeks since the part was coming from germany. They replaced the mechatronic unit and autohold button. The car is not jumping now but I have a feeling the problem is coming back since it does not go smoothly from stop to drive sometimes. Autohold button is working. If the autohold button is not on, a car is still rolling back on a mild slope so you have to move your foot quickly from brake to gas and pray there is no car behind you. 2010 vw Passat performs very well after you reach 60 miles and over but below that speed, it takes times to pick up a speed. Sometimes, the gas pedal hits the floor and a car is still not picking up the speed. Driving in a sport mode does not help, since the traffic is on stop and go.
