2018 Porsche Cayenne Engine Problems

INTERMITTENT LACK OF ACCELERATION WHEN TAKING LEFT TURNS FROM A DEAD STOP. CAR WAS A DEALER LOANER WITH 9000 MILES ON SPEEDOMETER. I PURCHASED THE CAR IN AUGUST, 2018. WITHIN THE FIRST 1000 MILES AND IN LESS THAN FOUR WEEKS I EXPERIENCED A SERIOUS LACK OF ACCELERATION ON TWO OCCASIONS WHEN MAKING A LEFT TURN, I REPORTED THIS TO THE DEALER AND WAS ADVISED THAT IT WAS PROBABLY DRIVER ERROR CAUSED BY OPERATING THE BRAKE AND ACCELERATOR USING BOTH FEET. I DO NOT DRIVE AN AUTOMATIC CAR USING TWO FEET. ALSO, I WAS TOLD BY THE DEALER THEY CHECKED WITH PORSCHE AND THERE ARE RECORDS OF THIS TYPE OF EVENT. I CHECKED ON THE INTERNET AND THERE ARE NUMEROUS IDENTICAL COMPLAINTS DATING BACK SEVERAL YEARS. THIS LACK OF ACCELERATION HAS OCCURRED FOUR MORE TIMES. THE DEALER HAS BEEN RESPONSIVE AND KEPT MY VEHICLE ON TWO OCCASIONS TO TRY AND DUPLICATE THE EVENT TO NO AVAIL. ON ONE OF THESE OCCASIONS THE DEALER REPLACED THE TRANSFER CASE BUT THIS DID NOT SOLVE THE PROBLEM. FINALLY, THE DEALER CALLED IN THE PORSCHE ZONE MANAGE WHO I AM TOLD WAS WELL AWARE OF THIS CONDITION AND REFERRED TO IT AS A SAFETY FEATURE TO PREVENT UNINTENDED ACCELERATION. HE CLAIMED THAT THIS IS PERFECTLY NORMAL OPERATION. I CALL IT A SAFETY HAZARD. IN FOUR MONTHS I HAVE DRIVEN THE CAR 3200 MILES. THIS SO-CALLED SAFETY FEATURE HAS ENGAGED ON ONLY SIX OCCASIONS, ALWAYS ON LEFT HAND TURNS FROM A COMPLETE STOP. WHEN THIS HAPPENS I NEVER KNOW WHEN THE ACCELERATION WILL CUT OUT OR HOW LONG I WILL NOT BE ABLE TO ACCELERATE. UP TO NOW, THE FEATURE HAS NEVER ENGAGED IN RIGHT HAND TURNS, IN FORWARD OR REVERSE. I HAVE CHECKED THE OWNERS MANUAL CAREFULLY AND THERE IS NO MENTION OF "UNINTENDED ACCELERATION" NOR IS THERE ANY MENTION OF A SAFETY FEATURE PROGRAMMED IN THE CAR. I HAVE REQUESTED THE DEALER TO BY PASS OR ELIMINATE THIS FEATURE BUT THET SAY PORSCHE WON'T ALLOW IT.
