My vehicle will disengage forward or drive at times (transmission) unknowingly and as you apply the gas it sometimes will engage and go forward or reverse in a high speed. Stopped at a light or stop sign becomes dangerous as you are not in control of your speed. Or you may be moved into traffic and lose forward or reverse power.

Gas pedal was stuck on full throttle on my way to work today. Pedal was all the way down and RPM's were racing as I was pushing the brakes and trying to get onto the shoulder of the highway. Very scary situation and I came close to a collision with multiple cars trying to get the car to a safe area. I was able to turn the ignition off, but the pedal stayed in the down position for over 2 minutes even with the car off. This was definitely not a floor mat issue and nothing was blocking the pedal.

Traveling on the freeway at 60mph. The esp(stability control) and epc lights came on. 5 seconds later the engine shuts off and I keep rolling at 60mph but decreasing speed. Luckily I was on a straight away and there was no need to turn but once the engine turned off the steering wheel was hard to turn and I could not pull over. There was an exit and I was able to stop on the off ramp. After putting the vehicle in park. I took the key out then, put it back on the ignition and tried to turn the vehicle on. The vehicle would not turn back on. When it finally turned on the vehicle stalled back off and the "check engine" light came on. After sitting in the vehicle for 5min in off. I then turned the vehicle on and it started off. I went to the dealership and told them what had happen they told me that it had never happened before with other Audi's but that it sounded like it was the crank shaft sensor. After looking online and doing research many other Audi owners had the same problem they stated that the "engine speed sensor" aka crankshaft sensor would go out and their engine would stall while driving. This is a safety issue! airbags go off when the engine shuts off and the steering wheel is hard to be turned. Please do something about it!

I have two Audi A4's, one a 2007 sedan and one a 2008 station wagon. Both exhibit the problem. Both have done it a number of times, mostly the sedan. When you need to scoot across opposing traffic making a left, sporadically, the car initially responds like you'd expect to the gas pedal, but half a second later bogs out with basically no acceleration, so you're rolling leisurely across oncoming traffic, and then about a second later it wakes up and resumes accelerating. I'm serious. Both cars do it, largely turning left. I've told the dealership about it several times and they always say they checked the computer and couldn't find anything wrong. The Audi are the only cars I've had with this problem.

I have an Audi A4 2007. Friday, March 5 I was driving to work and the car starting revving by itself, but slowing down at the same time. I was forced to put it in neutral and coast to the side of the road. Took it to the dealer, they said it was the fuel pump, replaced it. Saturday, I was the last car on an exit ramp preparing for light to change, but when I pushed the gas, the engine revved to 5, but would not move. Car was in drive position. While this was happening, a Ford F-150 was heading towards the rear of my car, but swerved in time I assume after seeing my hazards on, which I did immediately. The truck barely missed clipping me. Finally, I turned the car off and back on, and it got up to about 20 miles per hour, enough for me to get off the exit ramp. This car burns oil through every 1200-1500 miles. Audi is aware of this problem, in addition to the ignition coil problems with this vehicle. I had 4 coils replaced, but only after I got the letter of the recall from Audi. I was told the whole time the jerking of the misfired coils was 'normal'. I am not the only one who has had the same issues. This year of car is unsafe, and should be recalled to fix the oil consumption issues before the damage occurs to the engines.

The accelerator pedal of my 2007 Audi A4 convertible has stuck twice. Both times, I stepped on the brake and it released immediately, so I never reported it or asked the dealer to look at it. No resulting injuries, but obviously a concern -- perhaps Toyota isn't the only make with this problem.
