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.

THIS ISSUE HAS BEEN HAPPENING SINCE THE CAR WAS DELIVERED, WHICH WAS SIXTEEN MONTHS AGO. PORSCHE HAS MADE LITTLE EFFORT IN FIXING THE ISSUE.

SEVERAL TIMES A MONTH WHEN MY CAR COMES TO A STOP THE BRAKES MALFUNCTION AND THE BRAKE PEDAL GOES TO THE FLOOR AND THE POWER STEERING STOPS WORKING. IT TAKES UP TO ANOTHER CAR LENGTH TO FULLY STOP WHEN THIS HAPPENS - SOMETIMES JUST A FEW EXTRA FEET. IT HAS CAUSED ME TO DAMAGE THE FRONT END BY DRIVING INTO A BUSH. THE DEALER REFUSES TO DO ANYTHING BECAUSE THEY CAN'T REPLICATE THE BRAKE PROBLEM AND THEY STATE THE STEERING PROBLEM IS NORMAL. I HAVE BEEN ABLE TO REPLICATE THE STEERING PROBLEMS TO THEM BUT BECAUSE THE BRAKE ISSUE HAPPENS ONLY A FEW TIMES A MONTH I WAS NOT ABLE TO.
