The brake and gas pedals are too close. I consistently hit the brake while accelerating. They need to be spaced farther apart, and the brake pedal moved to the left. There are comments all over the internet about this problem and audi service says there is no fix. I have large feet and have never had this problem with any other car manufacturer. I need the nhtsa to get involved before someone gets hurt. This is a very big defect that needs to be fixed.

2004 Audi A8LSuspensionAcceleration & cruise controlEquipment & accessories

I own a 2004 audi a8 quatro, this morning the car accelerated on it's own. The driver seat, steering wheel, and the car suspension adjusted automatically while I was driving it and it went from 40mph to 150+ without me having my foot on the accelerator. For a minute I thought I was going to die. I slowly starting pressing on the brake pedal hoping the car would not flip. It took about 2 to 3 minutes for me to slow down the car. I put the emergency brake and turned it off. I turned it back on and the engine was still accelerated, it sounded it like the accelerator was stuck even though the car was on park. *Tr
