Porsche announced their "campaign" (recall) on November 14, 2017. I have called several Porsche dealers since that time, and the parts for this recall are not available. One dealer says it could be "another couple of months" before the part is available. The ah10 campaign says that this situation can cause a fire! is this what Porsche is waiting for? something needs to be done to get them to produce the parts necessary to prevent significant injury or death.
Its seems to be transmission is slips into four wheels drive, sometime it stuck in a drive gear.
Crack in original plastic coolant pipes.
2004 Porsche Cayenne s. Consumer writes in regards to reimbursement for vehicle fire damages.
**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!.
The air bag and the check lights came on. The consumer contacted the dealer and they said they could not service the car until 10/17/2005. Called Porsche customer service, and they said they could help. The consumer believed this was a safety hazard, and he did not want to drive the car.
Porsche lurches,jerks,thuds,intermittent power loss when accelerating to pass another car. Engine,transmission/turbo system faulty and hazardous as power loss occurs when quick speed-up when passing power is critically needed. This power failure problem has occurred since car was bought new ivy me in 2004.
