| Description of the problem | **uncontrolled acceleration** cayenne s accelerated uncontrollably while driving. While driving at approx 60 mph, i encountered traffic ahead and took my foot off the accelerator, however the car began accelerating. I tried lifting the pedal with my foot, no luck, applied the brakes and the car slowed, however, when i removed my foot from the brake, the cayenne continued to accelerate. The cruise control had not been activated and was off. I kept pressing the gas pedal and releasing it at least a dozen times and finally the cayenne stopped accelerating on its own, only to lose any control to accelerate. I coasted into a parking lot and stopped the car. Turned it off and restarted - i was able to drive, however acceleration was very slow and gear indicator on the dash cluster displayed a black 'd' in an orange square. This is a symbol that does not exist in the owners manual. The car shifted through gears normally. The rapid uncontrolled acceleration repeated itself and i was able to pull into another parking lot, slowing and stopping the car thanksto massive 14" front brakes with 6 piston calipers and 13"+ rear brakes with 4 piston calipers. I turned the car off for a few minutes and restarted. Gear selection indicator appeared normal and i was able to drive off, however acceleration was still veryslow. Drove home with the rapid acceleration repeating itself again and then stopping after a few miles. The only reason this did not cause a crash is the massive braking power of the cayenne and astute driving. I ran diagnostic software when i made it home and there was an "accelerator module" failure reported. The tail lights, alarm, central locking, and the ability to open the tailgate at all have also failed - "rear lighting control module" failure. So while driving, my tail lights failed, car accelerated uncontrollably and failed to accelerate in a safe normal manner. This is a major safety issue and should be promptly addressed! |
