The contact owns a 2021 Porsche Cayenne. The contact received notification of NHTSA Campaign Number: 25V896000 (Back Over Prevention); however, the part to do the recall repair was not yet available. The contact stated that while in reverse(R), the rearview camera failed to display a clear image on the screen. No warning light was illuminated.

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.

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 obstr...
Dashboard leather is separating and was told this could affect the airbag deployment in the case of an accident. Porsche dealership is asking 10k outside of warranty to replace the dash. If it was just cosmetic I could deal with it, but now that it is a safety concern for my passenger I feel forced to overspend. Even a reduced amount would help but a whole dash replacement sounds excessive to make...
Much like thousands of Cayenne drivers, I am constantly let down by an ongoing issue with Adaptive Cruise Control failures with an error message that reads, “Adaptive Cruise Control unavailable.” THIS MAY CAUSE SERIOUS INJURY OR DEATH IF NOT REPAIRED AS VEHICULAR COLLISION RATES INCREASE DRAMATICALLY TO NO AVAIL. Porsche dealers are notoriously recalcitrant about taking adequate responsibility f...
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...
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...
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 g...
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 th...
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 ...
when decelerating and car is in gear 2 it lurches the car forward while braking, basically fighting the attempt to slow the car down. I attribute this to aggressive downshifting, but is a safety issue because the operator then needs to compensate by pressing down on the brake pedal harder to stop the car. This has happened inconsistently when driving, but occurs more frequently than not.
On my Porsche Cayenne e-Hybrid model, the check engine light came on at less than 1000 miles. Porsche does not know why this happens but I've heard them claim that it's a software problem that has to do with how the car communicates with the charging system. Based on my research, there has been many other owners of the same vehicle with this problem. My vehicle has been in the shop for well ove...
When the vehicle is decelerating and the transmission is in gear 2 the vehicle will lurch forward interfering/fighting with the normal operation of the brakes. This consistently happens when braking to a stop. The vehicle has 260 miles and I have driven it perhaps 4 - 5 times for a total of 30 miles. This is demo vehicle bought from a Porsche dealership and under full warranty.
Check engine light thrown intermittently and dealer is unable to reproduce issue. Multiple incidents of the same issue by other owners. https://rennlist.com/forums/cayenne-9y0-2019/1248120-grr-cel-code-654-miles-on-new-21-cayenne.html Pattern is the same. Take delivery of new car, get CEL <1000 miles, take to the dealer and dealer is unable to permanently fix or reproduce.
