In October 2006, purchased a new 2006 Audi A4 from carousel Audi in golden valley, mn. The car was well maintained and has less than 62,000 miles today. In late summer of 2013, I began noticing that the car jerked heavily when putting it into reverse from a parked position. The car has an automatic transmission and I then began noticing the car not accelerating properly and laboring when nearing 50 mph on the highway. The motor would rev up and make an unusual sound and it was too dangerous to drive on the highway. I brought the car to the Audi dealer and they advised me that the transmission and computer module were not communicating properly and that it needs a new module at a cost of about $3800. They refused to pay for any of the repairs. When I asked both them and Audi north America about a class action lawsuit regarding similar problems with 61,000 other Audi owners across the u. S. , they refused to discuss the matter. I believe that Audi has knowingly made and sold a defective vehicle that is dangerous and poses great risk to its owner and other drivers on the road. I believe that Audi should be forced to stand behind their product and recall vehicles with this well documented defect and pay for my repair as well as for other owners who have similar problems.
