2021 PORSCHE Cayenne

Odometer Fraud. The contact purchased a 2021 Porsche Cayenne. It was discovered that there was a mileage discrepancy. The vehicle was a dealer sale. At the time of purchase on 5/29/25, the mileage was 21,000. The contact had taken the vehicle to another dealer for other repairs, and the dealer informed the contact that the vehicle was flagged for Odometer Fraud, and the actual mileage was 90,000. The dealer found an odometer tampering device still located on the vehicle, but deactivated the device. The contact called the State Attorney General's Office for New Jersey.

I am reporting a safety defect with my 2021 Porsche Cayenne GTS. The leather dashboard is delaminating and lifting away from its underlying structure. This defect is concerning because: The delamination is occurring on the drivers side but will eventually expand in the area covering the passenger-side airbag. If the airbag deploys, the raised/lifted dashboard material may interfere with or obstruct proper deployment, posing a serious risk to passenger safety. Porsche Cars North America (PNA) has been notified, but they classify this issue as “cosmetic” and refuse to repair it voluntarily under warranty or goodwill. Furthermore, The issue was not disclosed by the dealer at purchase. I have consulted two Porsche dealerships, both of which confirmed Porsche considers this a cosmetic defect not covered by the Certified Pre Owned warranty. However, given the location and potential interaction with the airbag system, I strongly believe this constitutes a safety-related defect that requires investigation. Online forums show this is a common issue across many models made by Porsche during this time but specifically SUV's. I am requesting that NHTSA investigate this issue to determine whether the delaminating dashboards in Porsche Cayenne models create a safety hazard that requires a recall and mandatory repair.

I was driving the auto and parked in my garage without any indication of a fault. I attempted to start the car about 30 minutes later and the car would not start and gave an error message that said "change driver" I tried both keys and neither would allow the car to be started. There was no starter noise indicating a weak battery. I had to have the car towed to the dealer after the tow company found a way to unlock the drive shaft with a key that is part of the car service tools. I could not move the car if I had stopped on a roadside. The dealer had never seen this issue before. The car was in the shop for a week to correct the fault from March 23 to March 31. The dealer claimed it was a software fault. There were no warning indicators or messages that something was wrong with any component or system.

Problem with the hybrid system and the engine control system. Unit changed automatically and unexpectedly from battery power mode to engine power mode when on battery power mode only. This change is not supposed to happen. This failure happened when starting the unit, put on drive and starting to move forward. This failure caused the unit to charge forward with more power unexpectedly. Causing almost to collide. At the time of the failure “engine control system” warning and “e power not available” warning lid up. The unit has been for service for 10 times with the same warnings powering up. At this time the unit has been on service for almost four month.

The car is notifying me that the drivers airbag is not working. the message that appears is: “Airbag system error, please visit workshop”

othe car's tach increase several hundred RPM as the computer tries to match revs when downshifting from 3rd to 2nd gear in Normal Mode and 2nd to 1st gear in Sport Mode.. When that happens, the car lurches forward. owhat seems to be happening is the engine is over-revving while disengaged from a gear on shifts from 3rd to 2nd and even more so on 2nd to 1st causing a lurch forward when the lower gear engages

The contact owns a 2021 Porsche Cayenne. The contact stated that while driving from a complete stop, the steering wheel felt loose. There were no warning lights illuminated. The vehicle was towed to the dealer where it was diagnosed that the tie rod bolt, track bolt, and hexagon head bolt needed to be replaced. The contact stated that the vehicle was repaired; however, the failure persisted and the steering wheel was making abnormal sounds. The vehicle was taken to a second dealer - Porsche South Shore (185 W Sunrise Hwy, Freeport, NY 11520) who test drove the vehicle but could not determine the cause of the abnormal sounds. An unknown part was replaced. The contact stated that the failure reoccurred while driving and she could not control the vehicle. The vehicle was taken back to the second dealer. The vehicle was not repaired. The manufacturer was notified of the failure but did not provide any assistance. The failure mileage was approximately 750.

While coming to a stop the vehicle lurches around 1200 rpms as the rpms are falling. The vehicle appears to already be in 1st gear when this happens. This can be replicated in all driving modes. observation: when braking or even when coasting to a stop the vehicle will slow down rapidly, as if the brakes are being tapped hard (the brake pressure is constant and occurs even when not braking) for a brief second and then release causing a lurching motion. This lurching motion is enough to concern while driving as a possible loss of traction. it feels as if the car is engine braking. This issue puts the driver, passengers, and other vehicles at a safety risk. I have had passengers state that it gives them motion sickness. I have reported this to the dealer and they had the car twice. The second time was for a substantial amount of time. The dealer is on record stating that they can recreate it, observe it, but have not been able to fix it. they have reset the software on several systems including the transmission. there are no third party devices on the car, the car is stock, there are no warning lights.This has been the case since day one of having the car (brand new).
