Owners have filed 13 complaints
about the 2025 Porsche Cayenne with NHTSA between 2025 and 2026.
The largest single group is the driver assist & collision avoidance.
Across this model's run it ranks 9 of 18 worst.
The letter says how bad. This says what kind — whether this year drew
an unusual number of complaints, unusually dangerous
ones, or failures that arrived unusually early.
The dashed ring is 50 — the national norm. Further out is worse.
Complaint volume — 17
Against the median year of the Porsche Cayenne. 50 means typical for this
model; 100 means roughly double.
Severity — 100
46.2% of these complaints
involved a crash, fire, injury or death, against a national rate of
9.7%.
Early failure — not reported
Too few complaints recorded a mileage to measure this.
How 2025 compares with every other Porsche Cayenne
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

Recalls on the 2025 Porsche Cayenne
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.
Canada — Transport Canada
Canada runs its own recall programme, and its campaigns do not
always mirror the American ones.
Recall 202571625,175 units in Canada
Visual System
Issue: On certain vehicles, a software problem could cause the rearview camera image not to appear on the display. Canadian regulations require the rearview image to display when the transmission is shifted into reverse gear. Safety Risk: A rearview camera image that doesn't display could reduce a driver's ability to see behind the vehicle while backing up. This could increase the risk of a crash. Corrective Actions: Porsche will notify owners by mail and advise you to take your vehicle to a dealership to update the driver assistance system control unit software.
Recall 202549814 units in Canada
Fuel System
Issue: On certain vehicles, the connections on the high-pressure fuel pumps may not have been tightened properly. As a result, the fuel could leak. Note: This recall only affects certain vehicles equipped with a V8 engine. Safety Risk: A fuel leak can create the risk of a fire. Corrective Actions: Porsche will notify owners by mail and advise you to take your vehicle to a dealership to inspect the connections on the high-pressure fuel pumps. The high-pressure fuel pump(s) and fuel line(s) will be replaced, as necessary.
Recall 20243391,823 units in Canada
Lights And Instruments
Issue: On certain vehicles, a software problem could cause the headlamps to become incorrectly aimed while reversing. As a result, the vehicles may not meet certain requirements of Canadian regulations. Safety Risk: Headlamps that aren't aimed correctly could cause reduced visibility and/or glare for oncoming drivers and could increase the risk of a crash. Corrective Action: Porsche will notify owners by mail and advise you to take your vehicle to a dealership to update the central control unit software.

ELECTRICAL SYSTEM
My 2025 Porsche Cayenne S was involved in a low-speed crash and experienced multiple safety failures related to the Driver Assistance Control Unit, including phantom braking and camera failure. This crash, I believe, is a direct result of the safety defect identified in Recall ASB2 (NHTSA 25V896), which causes the Driver Assistance Control Unit to fail to process image and sensor data correctly. My vehicle has exhibited a dangerous pattern of electronic and sensor instability that aligns perfectly with the technical failures described in the recall: The Collision: While reversing in a parking garage on November 25, 2025, I struck a wall because the rearview camera and parking sensors failed to provide any notification or visual feed. I now understand this was caused by the "transient signal noise" cited in the recall, which prevents the system from detecting obstacles in specific lighting environments. Phantom Braking: On two separate occasions, the vehicle abruptly "slammed" on the brakes for no apparent reason, nearly causing high-speed rear-end collisions. When reported to The Collection Porsche Service on January 23, 2026, the Service Manager admitted the system is hypersensitive to shadows. This confirms the control unit is failing to correctly interpret image data—the exact root cause of the current recall. Total Electrical Failure: On December 2, 2025, the vehicle suffered a defective alternator, causing a total shutdown in a live intersection. This resulted in a seven-week repair (completed Jan 23, 2026). Unstable voltage from a failing alternator is a primary source of the "signal noise" that causes the driver assistance systems to malfunction. I initially believed the bumper contact was a personal error. However, given the documented failure of the alternator and the subsequent recall regarding camera/sensor data processing, it is clear that the vehicle’s safety systems were compromised at the time of the incident. Porsche NA has been notified.

FUEL/PROPULSION SYSTEM
The car was driven from Cheshire, CT to Old Tappan, NJ about 90 miles, just under two hours drive time. Combination of highway and back roads. The car was in drive in comfort mode proceeding slowly (approx 20 mph) down a street within a condo complex. As I approached the driveway I lightly braked, turned into the driveway then lightly pressed the accelerator to bring the car up the driveway apron onto the single car length driveway. At that point the car accelerated to what felt like max power. The car accelerated uncontrollably causing the car to advance in a right turn through the closed garage door striking a garaged vehicle in the right rear quarter and the right wall of the garage. Fortunately no one was hurt but this could have resulted on severe injury or death. No pre warning lights just a slight burning smell just before. This unrequested acceleration occurred twice before the crash incident leaving a traffic light from stop. Porsche has analyzed the car and find no fault. The insurance company has sent an adjuster. Damage estimated at $73,000.00.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
At approximately 57 miles after delivery of a new 2025 Porsche Cayenne, the Adaptive Cruise Control (ACC) and related driver-assistance safety systems failed while the vehicle was traveling at approximately 67 mph. There had been no collision, impact, or abnormal event prior to the failure. Porsche’s diagnostic logs (PIWIS) confirmed the system failure occurred while the vehicle was traveling at approximately 67 mph. A physical inspection of the vehicle showed no evidence of collision, abnormal G-force event, or exterior damage that would explain the system failure. The malfunction disabled a key driver-assistance safety feature on a nearly new vehicle. The vehicle was returned to the selling dealer for repair and the manufacturer, Porsche Cars North America, was notified. Both the dealer and manufacturer indicated that the issue was not considered a defect and declined to provide further explanation as to how such a failure could occur at extremely low mileage without any external factors. Given the extremely low mileage at which this safety system failure occurred, this may indicate a defect affecting the vehicle’s driver-assistance or ADAS systems. A failure of Adaptive Cruise Control and related driver-assistance systems at highway speed raises potential safety concerns for vehicle occupants and surrounding traffic. The failure occurred at extremely low mileage with no apparent triggering event, raising concern about a potential premature failure of a safety-related driver-assistance system.
