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 sure the leather is not obstructing the airbag.Owner report · Unknown Or Other · Jun 2025
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.Owner report · Electrical System · Mar 2023
The car is notifying me that the drivers airbag is not working. the message that appears is: "Airbag system error, please visit workshop"Owner report · Air Bags · Oct 2022
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 engagesOwner report · Unknown Or Other · Aug 2022
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.Owner report · Service Brakes · Nov 2021
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.Owner report · Power Train · Sep 2021
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.
