While driving my 2019 Porsche Cayenne S on the freeway, the check-engine light came on, followed by a message on the dashboard that read “Engine Control fault – Driving permitted – Visit workshop.” Moments later, the vehicle suddenly lost power and decelerated from about ~75 mph to around 55 mph, even though my foot was still on the accelerator. I am [XXX] pregnant and had our [XXX] child in the car at the time. The unexpected loss of speed in fast-moving traffic was frightening. I had to quickly change lanes to reach the slower lane and avoid being hit by other vehicles. After reaching safety, I drove the car to an authorized Porsche dealership, where technicians found an active water-pump leak with coolant entering the vacuum system, which may have caused turbocharger and engine-power failure. This is after I replaced the water pump last year at another porsche dealership. A photo taken during the incident shows the dashboard warning message as it appeared. This incident created a serious safety hazard, as the vehicle displayed “driving permitted” even though it was at risk of a sudden loss of propulsion at highway speeds. The car and the failed components are available for inspection. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

THERE'S AN ELECTRICAL ISSUE WITH THE VEHICLE (it is an E-Hybrid) with ERROR MESSAGES THAT RUN IN A CONTINUOUS LOOP (ACC NOT AVAILABLE, PAS RESTRICTED, DRIVING LIGHT CONTROL ERROR, HIGH BEAM ASSIST NOT AVAILABLE, LANE KEEP ASSIST RESTRICTED). THE LOCAL DEALER HAS NOT YET BEEN ABLE TO FIX THE ISSUE. CAR IS UNDER WARRANTY AND HAS BEEN IN THE SHOP FOR A MONTH. WE WERE CALLED TWO TIMES TO PICK UP A "FIXED VEHICLE" AND EACH TIME WE HAD TO RETURN THE CAR ALMOST IMMEDIATELY UPON LEAVING THE DEALERSHIP SINCE THE PROBLEM WAS NOT FIXED. I'VE CONTACTED PORSCHE CUSTOMER SERVICE BUT AS OF YET THERE IS NO RESOLUTION. IT IS VERY CONCERNING SINCE SOME OF THESE ERROR MESSAGES DO AFFECT VEHICLE SAFETY.

The surround video camera system frequently fails. One, several and sometimes all cameras randomly fail when triggered by placing transmission in reverse to park. Image is replaced by icon of camera with diagonal line through it. The dealer has attempted to fix this problem 4 times without success. They replaced all cameras and the video control unit. Many other owners of Porsche Cayenne, Macan and Taycans have reported this problem on various Porsche blogs. No one has reported a solution to the problem. The cameras are restored after turning off vehicle, leaving vehicle and locking vehicle. After waiting at least 15 minutes before rebooting vehicle, the cameras function normally. I have spoken to other Porsche dealers and none are aware of a solution to this problem. I have registered a complaint directly with Porsche and have not received any response in over 6 months.
