The Porsche Cayenne is notorious for drive / cardan shaft failures. Had bad drive shaft noises, and subsequent premature failure, it was a worn center support dampener and a faulty center support bearing. I experienced banging, bumping, grinding noises from my Porsche Cayenne and was unaware at the time it was the drive shaft. I have outlined the the noises and causes below: - a clanking or clunking noise while accelerating or from deceleration to acceleration around 35to 40mph and while Cayenne was shifting from 2nd to 3rd to 4th gear. Around 5th and 6th gear going around 50-60 mph it stopped. If I kept the rpm under 200 it seemed to run ok, no issue, but if I pressed the accelerator hard or gunned it, it went haywire. It was the result of a worn and damaged dampener or diaphragm located on the center support bearing. This condition will allow for the drive shaft to travel up and down with variations in drive line torque. This movement will produce a loud clanking or clunking sound and make for a very uncomfortable ride. I later found out that this condition is one of the most common failures on the Cayenne drive shaft, all models 2003 to 2006. This should be a recall and free fix by Porsche because it has happened to so many of the vehicles and model years stated above! but no, Porsche quoted me $2,500 to fix it. Not fix the problem area, the hard rubber dampener on the center support shaft of the power train, which by the way is possible. No, Porsche would only replace the entire power train for $2,500.
The contact owns a 2004 Porsche Cayenne. While driving approximately 60 mph, the contact heard a ticking noise followed by a loud, thumping noise which caused the vehicle to accelerate. The local authorized dealer stated that the bearing and drive train needed to be replaced. The manufacturer had not been notified. The vehicle was being repaired by the dealer. The VIN was unavailable. The current mileage was approximately 93,000. The failure mileage was approximately 90,000.
I own a 2004 Porsche Cayenne s and from the very first day of ownership the car has a serious hesitation problem when accelerating. I have had the car serviced at the Porsche dealership (mckenna in norwalk, CA) and they tell me that they are very aware of the problem and there is no way to fix it. Many, many Cayenne owners are having the same problem and Porsche refuses to fix the problem. I have had several near-miss collisions because of the cars hesitation when accelerating. Please help and let me know the status of this dangerous issue. Thanks, derek dean.
While turning across traffic from e 2nd Ave onto josephine st. The accelerator pedal was depressed to the just above the floor and no discernable acceleration response was noticeable for a second or two. When there was an acceleration response it was an explosive, 'off to the races' one. This incident took place after the dealer advised that: unofficial fixes (dme update and transmission adaptation) issue had been in place since the delivery of the vehicle; vehicle had been into the dealer to evaluate/address this issue three times; on the third visit the transmission control module was replaced/updated/adapted and dme control unit was remapped.
While merging from highway 141 onto I-70 the accelerator pedal was depressed to accelerate from highway speed to merge into interstate traffic and no noticeable acceleration was apparent. The extremely concerning about this incident was that this merge was being executed between two 18-wheelers. While there was ample space to merge if the vehicle had responded without hesitation to accelerator pedal inputs, the experienced hesitation made the merge dicey.
While pulling out from a parking lot into major city street the vehicle hesitated to respond to accelerator input with approaching traffic. The vehicle moved off from a stop and into the closest lane fine but would not accelerate as more accelerator pedal was applied. There was noticeable delay/hesitation, as traffic bore down on me, before the Cayenne decided to accelerate. Contacted dealer who noted that there was an unofficial fix that may address the issue.
Customer campaign notice received regarding main wiring harness routing. As well as problems with engine not responding to accelerator pedal. The vehicle's engine unexpectedly does not respond to input on the accelerator peal. This problem has occurred so many times that the consumer decided to put the vehicle in storage and no longer drive the vehicle. The consumer has complained to the dealer several times to no avail. The dealer insist that this is a characteristic of the vehicle.
