On January 28, 2019 I was driving to my medical appointment at 35 miles per hour when my car froze up then bucked and now no longer the transmission will no longer engage. Upon research Audi has known of this transmission having serious faults and that it will break down without warning. Audi has refused to do any recall on these transmissions, even after a class action that was settled, Audi will not do any recall.
03 Audi A4 6 speed auto cvt transmission, this vehicle has known issues with shifting from 1st to 2nd gear too soon. While driving this vehicle from a complete stop on an on ramp on rt 80 I hit the gas and it would shift from first to second and back to first then lurch forward while rolling. While this is going on I am trying to merge on the highway which put my car into the right lane doing about 2 mph with traffic (which would be a safe distance if this issue didn't happen) having to come to an abrupt stop not to hit my car. This is an known issue with these transmissions and there is no recall on them since new. I have experienced this issue numerous time as many others with this vehicle does. There are numerous forums with consumers complaining of the same issue. This needs to be addressed before someone gets hurt.
