Owner report 11433244 · 2021-09-16 (September 16, 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 11439658 · 2021-11-08 (November 8, 2021)
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 11531025 · 2023-07-08 (July 8, 2023)
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 ser…

Owner report 11543394 · 2023-09-08 (September 8, 2023)
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. Th…

Owner report 11453559 · 2022-02-23 (February 23, 2022)
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 fe…

Owner report 11453894 · 2022-02-24 (February 24, 2022)
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) wh…

Owner report 11744923 · 2026-06-18 (June 18, 2026)
Vehicle Information: 2021 Porsche Cayenne E-Hybrid (VIN: [XXX]) Description of Defect: While operating the vehicle, the steering column bolt physically backed out and detached, causing an immediate, complete loss of steering control. This exact mechanical failure mirrors NHTSA Safety Recall 21V-493 (Porsche Campaign AMB4), which addressed loose, under-torqued steering column bolts leaving the factory. My specific VIN was excluded from the narrow initial recall population, proving a factory tracking failure by the manufacturer. The authorized …
