1 Cruise Control problem of the 1999 Audi A6

Failure Date: 01/23/2015

While driving 60 mph on the freeway, the car accelerated on its own to 72 mph as if going into cruise control. Confirmed the cruise control switch was turned off. Applied the brakes seven times. Car did not respond to braking. Engine seemed to race against the brakes. I put the car in neutral, moved to side of the road. Applied the hand brake. Turned key off. Car slowed then stopped. Since this incident the car was test driven twice by mechanics, during which it seemed to operate normally. On January 27, 2015 the car was taken to the local dealer, bellevue Audi, for diagnosis.

2 Cruise Control problem of the 1996 Audi A6

Failure Date: 02/11/2014

On the morning of February 11th 2014, my daughter was on her way to school when her vehicle began to accelerate on its own. She believes she was going between 25 and 35 miles per hour when the vehicle began to accelerate and topped out at 70 before she was able to get it to slow down. She stated to me after the incident that she had to press both feet on the brake pedal to get the car to stop. Fortunately there was no accident and she was able to safely pull over to the side of the road. I took her car to friend¿s house, dropped her off at school and took her vehicle to sunny side Audi in middleburg ohio. They found the speed control was malfunctioning. They told me that it would be between $800 and $1000 to repair. I paid them $138. 00 to disconnect the cruise control and we haven¿t had any continuing problems with the cruise control. The $138 isn¿t going to break me but then again breaking me is why I am writing this complaint. I have given this incident a lot of thought; what could have happened, how lucky we are that my daughter didn¿t panic and then I realized that there are more than likely many more 1996 Audi A6¿s out there and who knows other Audi¿s in general with the same cruise control set up that is installed in our car that have or will malfunction. I am hoping that someone will look into this incident. You are more than welcome to inspect our vehicle. I was surprised by the response of the sunny side Audi service department. They offered us no support or avenue for assistance for repair and treated this incident like any other vehicle repair. We were lucky it wasn¿t worse and we are grateful but I would like to be reimbursed and have the vehicle properly repaired.

3 Cruise Control problem of the 1999 Audi A6

Failure Date: 11/20/2010

On the morning of November 20, 2010, I was pulling in to a parking space at the local library, approximately 10 minutes from my home. As I was making the turn to pull into the parking space, I heard the engine rev, and the car accelerated as though the cruise control had "kicked in" and my brake would not stop the car. Rather than hit a car that was parked in front of my parking space, I turned the vehicle to go up a curb and hit a tree. Once the tree stopped the car, I was able to put the car in reverse, back down off the curb, put the car in park, and pull out the key. Oil was pouring out of the vehicle and it had to be towed to my home, was examined by my insurance company, and was written off as a total loss.

4 Cruise Control problem of the 1999 Audi A6

Failure Date: 01/21/2005

I was traveling on PA route 476 southbound approximately 8:30 pm, maintaining a constant speed of approximately 65 mph. The thermometer in my car reported an ambient exterior temperature of between 4 and 8â° f. The cruise control switch was in the standby position but cruise control was not activated. I began to notice that the car was maintaining speed without depressing the accelerator pedal. In fact, when traveling on level ground, the car accelerated to 80 mph until I depressed the brake pedal. The tachometer reported a constant engine speed of 2400 rpm with no pressure on the accelerator pedal. I attempted to change the engine speed by activating and deactivating cruise control, which did not respond at all. I next tapped the brakes to see if this would disengage a potential cruise control malfunction, again to no avail. The accelerator pedal was free of any obstructions and moved freely under my foot. As I approached the toll plaza, I required significant brake pressure to slow the vehicle down to approximately 15 mph. With full brake force, the vehicle would slow to approximately 5 mph but would not stop. I then put the transmission in neutral and the car stopped but the engine revved in excess of 6,000 rpm. I immediately shut the engine off. Upon restarting the car, the idle speed was normal. Thinking that the problem was icing and now resolved, I continued into philadelphia without incident. Upon my return to allentown the same night (approximately 10:30 pm), also on route 476, I experienced another episode of a stuck accelerator. I had been traveling at 65 mph for about 30 minutes when the problem recurred. The ambient temperature was 3â° f and the engine speed maintained 1800 ? 2000 rpm without any accelerator pedal pressure. Again, in order to stop the car, I had to place the transmission in neutral and quickly turn off the ignition key to avoid further engine damage.

6 Cruise Control problem of the 1998 Audi A6

Failure Date: 01/24/2003

1998 Audi A6 quattro: while driving on the highway coming to the exit ramp for m y home the car wouldnt stop. When the brakes were applied the engine kept on revving as if the cruise control was set, however it was off. Couldn't stop the car until luckily at the last minute the engine died and an accident with a stopped car at the end of the ramp was avoided. Two small children were in the car at the time and both were terrified. I calledthe local Audi dealer and they told me they have never heard of anything like that ever happening before. Then I see this site and realize that it has!!! the car just wouldn't stop!!!.

7 Cruise Control problem of the 1999 Audi A6

Failure Date: 01/01/2001

For the past several winters, my 1999 Audi A6 2. 8 quattro has had a failure in its cruise control mechanism. When ever it gets cold the cruise control often does not engage, and if it is really cold it may disengage after running for awhile even on level pavement (I. E. Not undo engine strain-normal for disengagement). The major problem lies in that, at least twice, even though the cruise control has not been made to engage on prior attempts, it has engaged latter on its own, without prompting, bringing the car up to speed. Case in point: one time when coming into a residential area, it suddenly engaged, and started to try and come up to highway speeds. The dealership has tried several attempts to rectify this fault, but has been unable to find a solution. I have even offered to drive my car up to their national headquarters for their engineers to look at. Now Audi USA, will do no more toward this effort, in what I consider a serious and possible dangerous matter.
