What owners reported
2021 Porsche Cayenne owner complaints in detail
Owner complaints4
ELECTRICAL SYSTEM
Owners of the 2021 Porsche Cayenne report persistent issues with the electrical system, particularly involving the Adaptive Cruise Control and hybrid system. Complaints frequently mention the Adaptive Cruise Control becoming unavailable, with repeated attempts at camera recalibration failing to resolve the issue. Another common problem involves unexpected switching from battery to engine power in hybrid models, leading to sudden acceleration and potential safety risks. Additionally, one owner describes a significant odometer discrepancy, suggesting possible odometer tampering. These issues are reported at various stages of vehicle ownership, with some vehicles undergoing multiple service visits without resolution. Safety implications include increased risk of collision due to sudden power changes and potential loss of control.
Owner complaints3
UNKNOWN OR OTHER
Owners of the 2021 Porsche Cayenne report issues with unexpected engine behavior and persistent check engine lights. Several complaints describe the car lurching forward due to the engine over-revving during downshifts from 3rd to 2nd and 2nd to 1st gear, particularly in Normal and Sport modes. Additionally, multiple owners of the Cayenne e-Hybrid model experience check engine lights appearing at less than 1,000 miles, with reports suggesting a potential software issue related to the vehicle's charging system. This problem often leads to extended service visits as dealers struggle to diagnose and resolve the issue. No safety implications such as crashes or loss of control are mentioned in the complaints.
Owner complaints3
AIR BAGS
Owners of the 2021 Porsche Cayenne frequently report issues related to the dashboard leather separating or delaminating, which they believe may interfere with airbag deployment. Typical symptoms include the leather lifting away from the dashboard structure, particularly on the driver's side, with potential to affect the passenger-side airbag area. Additionally, some owners receive dashboard notifications indicating an "Airbag system error." These issues often arise outside of warranty coverage, leading to significant repair costs. Although no crashes or injuries are reported, the potential obstruction of airbag deployment is a noted safety concern.
Owner complaints2
POWER TRAIN
Owners report issues with the 2021 Porsche Cayenne's power train, specifically involving lurching motions during deceleration. Complaints frequently mention that when the vehicle is coming to a stop, it lurches around 1200 RPMs, often feeling as if the car is engine braking or fighting against the brakes. This behavior is noted both while braking and coasting to a stop, and is observed in vehicles with very low mileage, including one with only 260 miles. Safety implications are highlighted by owners who describe the lurching as a potential loss of traction risk and note that it can cause motion sickness for passengers. These issues are reported from the point of purchase, suggesting they occur in new or nearly new vehicles.
