VEHICLE RUNS INEFFICIENTLY WHEN COLD AND SMOKE HAS BEEN NOTED FROM THE EXHAUST PIPE WHEN VEHICLE IS DRIVEN. IT WILL TURN OVER, BUT NOT CATCH. DEALERSHIP WAS TOLD BY PORSCHE TO USE A LOWER OCTANE FUEL (87) TO REMEDY THE PROBLEM. THIS CONTRADICTS THE INFORMATION IN THE OWNER'S MANUAL WHICH STATES ONLY PREMIUM UNLEADED FUEL 91 OR HIGHER SHOULD BE USED. IF THE VEHICLE IS TAKEN INTO A LOWER ALTITUDE AREA, THE FUEL SHOULD REVERT TO PREMIUM. THIS IS A BRAND NEW CAR AND IT DOES NOT START WHEN THE ENGINE IS TURNED OVER, LEADING ME TO BELIEVE THERE IS A MANUFACTURING DEFECT IN THE DESIGN OF THE ENGINE. MY HUSBAND OWNS A 2004 CAYENNE S, WHICH HAS A 4.5 V-8 INSTEAD OF THE 3.2 LITER V-6 AND IT STARTS IMMEDIATELY, EVEN WHEN COLD. *NM

S10 DIRECT REPLY LETTER TO THE SECRETARY FROM REGARDING HAVING PROBLEMS WITH HIS 2008 PORSCHE CAYENNE. *TGW THE CONSUMER STATED HE EXPERIENCED NUMEROUS SAFETY PROBLEMS WITH THE ELECTRICAL SYSTEM AND BRAKES. THE CONSUMER STATED HE FILED TWO SEPARATE ARBITRATION AGAINST THE DEALER AND THE MANUFACTURER. THE FIRST ARBITRATION CASE WAS SETTLED IN 2009, WITH THE EXPECTATION ALL OF THE PROBLEMS WITH THE VEHICLE, CURRENT, PAST AND PRESENT WOULD BE PROPERLY IDENTIFIED AND RESOLVED. SINCE THE INITIAL ARBITRATION CASE, THE CONSUMER HAD TO TAKE THE VEHICLE BACK TO THE DEALER 11 TIMES FOR THE SAME ELECTRICAL/SOFTWARE PROBLEM. THE ON-GOING PROBLEM UNCONTROLLABLY AFFECTED THE PROPER POSITIONING OF THE OUTSIDE MIRRORS AND THE OVERALL SAFETY ASPECT WHEN OPERATING THE VEHICLE. THE DEALER REPLACED THE ONBOARD COMPUTER CONTROL MODULE SEVEN TIMES, AS THEIR FIELD TECHNICAL EXPERT SUSPECTED THERE WAS AN UNIDENTIFIABLE ELECTRICAL SHORTAGE OR A COMPUTER RELATED SOFTWARE VIRUS SOMEWHERE WITHIN THE ELECTRICAL SYSTEM. THE CONSUMER BELIEVED THE DEALER HAD NO IDEA HOW TO RESOLVE THE PROBLEM.
