Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

2005 Audi A4 cabriolet with 38K miles, cvt transmission slips badly, won't accelerate, loud whining noise when cold. Audi has acknowledged problems with this transmission and extending warranty for 2004 and earlier vehicles, but not 2005 models, as settlement of class action lawsuit for vehicles with the same cvt transmission. Vehicle problem was diagnosed by Audi dealership as needing new transmission and provided a quote for replacement re-manufactured transmission ($6,687 and tax). Audi usa agreed in writing to assist with the expense by covering 50% of total cost to repair. Vehicle owner concerned about safety and reliability when driving vehicle in cold weather, especially when in traffic.

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"

A4 4-cyl

  • Automatic transmission
  • 400 miles
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.
