We are the 2nd owner of an Audi A4 convertible, purchased in November of 2010 with 25K miles. Within two years, we began to have problems with the cvt transmission and had to have the tcm replaced, which was later reimbursed by Audi as a result of a class-action lawsuit. In January of 2014, at 38K miles, Audi diagnosed the transmission as defective and needing replacement, transmission slipping when cold, vehicle shuddering. On complaint to Audi, they agreed to cover 50% of the costs, which would be approximately $7,000 which resulted in my wife being afraid to drive the vehicle in cold weather. Replace the transmission at half cost. At 47K miles, again cold weather, the problem has worsened, vehicle often won't reverse and transmission locks up unexpectedly. As the vehicle cannot be driven safely, my wife will not drive it until it is safe again. As there is documented evidence of known issues with this transmission (us district court # CV11-00665 bro agrx), Audi should be held responsible for 100% of the costs to repair and cvt transmission which results in a vehicle being unsafe to operate.

Stopped on a hill at a stop light, went to go and car lunged forward and died. Had to immediately apply brakes, car started again. Has happened multiple times. We are second owner, have only had the car for a year and found that the transmission control module for this vehicle was already replaced at 49,000 miles - under warranty to other owner. Now, at 130K miles we are being told it has to be replaced again. It is a danger to drive as they said the transmission could fail or even the gears could slip causing danger to the passengers. This particular model of Audi transmission, known as "multitronic" or "cvt" has numerous complaints and failures. We paid 12K for this car used and have a major malfunction within a year.

Shifting from second to third gear and the gas pedal went down to the floor and engine redlined rpms. I had to manually pull the pedal from the floor where the engine and pedal functioned as normal afterwards. I checked the floor mat and it was secure and away from impeding the pedal.

There is a huge problem it seems with the transmission control module (tcm). Apparently most Audi vehicles will have a problem with it and the repairs are costing the consumers big money. A new one from the dealer costs around 1100-1200.00 dollars and they are used to seeing this problem and don't think its a big deal... why should we pay if its a problem that they are aware about and ultimately comes down to a bad service by them knowing and not helping pay for a regular problem caused by them"?"

Audi A4 A6 issues with the transmission control module (tcm). My 2005 A4 car had approx 45,000 miles when the check engine light came on. I was taking the car in for am oil change so I had them check the issue with the engine light. I was told that it was the tcm and the car was registering faulty safety codes. I was informed that if I did not get it fixed the car could shut off while driving or the transmission could burn up while driving. I asked way there had not been a recall as it was a safety issue if the car could shut down while driving causing severe injury or even death. The university Audi service repr (jordan) stated it was up to Audi hq to make such a call. I asked if he had seen other issues. He stated yes that is why Audi came up with an updated part. I stated well if there was an updated part that means the old part was no good and a recall should have been issue. I called Audi hq and was informed that they track the frequency of part replace and determine a recall based on that. I replied what about safety and the death or injury of your customers. Why would you not evaluate an issue for recall based on safety" she indicated Audi values its customers, but relies on dealers to report issues. Sounds like everyone is in denial of who is responsible and accountable for the safety and lives of Audi car owners. Then, I was told the amount of more than $1800 dollars. I saw several complaints online about the tcm and cost of more than $2500. Now I know why they did not want to issue the recall, but instead update a part and charge its customers versus taking responsibility for the safety issue. I paid for the repairs, as it is my only source of transportation. I did not want to continue driving the car without the repairs as the dealer clearly stated there were safety concerns. Is this another hidden Toyota situation where the dealer is more concerned about profits over safety"

The vehicle hesitates for 2 to 3 seconds when trying to accelerate from a complete stop. From June 23rd, 2005, when I took delivery of the car, until July 1,2005, I have almost been T-boned while trying to make a left hand turn, 3 times. The car is dangerous!! I took it in to the dealer on July the 1st. They told me then that that is the way the car is designed to operate. I then contacted Audi customer relations, and was told the same thing by them. They are not willing to do anything about this problem and I beleive they hope it will go away. I have no way of checking, but I will guess that this is a chronic problems and has caused many accidents.
