“I HAD JUST RETURNED TO MY CAR AT A LOCAL SHOPPING CENTER, THE SKY HAD BEGUN TO LOOK AS IF A STORM WAS APPROACHING AND I DECIDED TO PUT UP MY CONVERTIBLE TOP. THE TOP WOULD NOT GO UP, SO I PROCEEDED HOME IN HOPES THAT I WOULD BEAT THE IMPENDING BAD WEATHER HOME. NEEDLESS TO SAY IT BEGAN TO STORM AND MY VEHICLE AND MYSELF WERE SOAKED. I WAS TERRIFIED AS I COULD BARELY SEE TO DRIVE. FORTUNATELY I MADE IT HOME BEFORE MY CAR CONKED OUT. I CALLED MY INSURANCE COMPANY AND WAS INSTRUCTED TO HAVE MY DISABLED VEHICLE TOWED TO THE PORSCHE DEALER. IT WAS THEN EVALUATED BY THE SERVICE TECHNICIAN, AND HE FOUND THAT A RELAY AND MOTOR HAD FAILED. THE DESIGN INVOLVES TWO RELAYS, ONE FOR THE LEFT SIDE AND ONE FOR THE RIGHT SIDE. THE LEFT SIDE FAILED AND WOULD NOT ALLOW THE CONVERTIBLE TOP TO COME UP. IN ADDITION TO THE MOTOR/ AND OR RELAY FAILURE IT CAUSED THE COWLING COVERING THE TOP TO JAM AND TORCHED IT, SO THAT IT BECAME FURHER DAMAGED. THE INSURANCE COMPANY AGREED TO PAY FOR THE DAMAGE CAUSED BY THE WATER, BUT NOT THE MECHANICAL FAILURE THAT CAUSED THAT. THE DEALER INFORMED US THAT THE MOTOR AND RELAY WERE NOT REPLACEABLE AS PORSCHE HAD REDESIGNED THE SYSTEM, BECAUSE OF…”
“THE AIR BAG LIGHT ILLUMINATED ON THE CAR SPONTANEOUSLY AND STAYS LIT AT ALL TIMES INDICATING A FAULT IN THE SYSTEM. FROM ALL REPORTS ON VARIOUS PORSCHE DISCUSSION FORUMS (THOUSANDS OF INCIDENTS THAT HAVE BEEN REPORTED AND DISCUSSED), THIS IS A COMMON PROBLEM IN THE FIRST GENERATION PORSCHE BOXSTERS. IT IS A DEFECT IN THE SEAT BELT BUCKLE AND SEAT BELT GROUND CAUSED BY CORROSION OF THE CONTACT POINTS FOR THE SEAT BELT THAT TRIGGERS THE LIGHT. THE PURPOSE OF AN AIR BAG LIGHT IS TO INFORM YOU OF A DEFECT IN THIS SAFETY SYSTEM AND TO NOTIFY YOU THAT THE SYSTEM WILL NOT OPERATE AS IT SHOULD. WHILE THERE IS APPARENTLY A TSB THAT WAS ISSUED BY PORSCHE, ONCE YOUR VEHICLE IS OUT OF WARRANTY THEY WILL NOT REPAIR IT UNDER THE TSB FOR FREE. THIS IS A WIDESPREAD AND COMMON SAFETY DEFECT THAT DOESN'T APPEAR UNTIL AFTER THE CAR IS OUT OF WARRANTY. THE COST TO REPAIR THIS PROBLEM IS APPROXIMATELY $1500.00 THROUGH PORSCHE. CONSIDERING MOST PORSCHE BOXSTERS FROM 1997-1999 SUFFER FROM THIS PROBLEM, IT SHOULD BE A SAFETY RECALL AND REPAIRED BY PORSCHE AT THEIR EXPENSE. *TR”
“WE BOUGHT A 1998 PORSCHE BOXSTER IN AUG 2009. SERVICED AS REQUIRED. ON 9/7/10 OUT DRIVING, STOPPED AT A STOP SIGN AS WE PROCEEDED THROUGH THE STOP SIGN THE ENGINE DIED, WHITE SMOKE CAME POURING OUT THE BACK. HAD IT TOWED TO MECHANIC AND WAS INFORMED THAT THEN MOTOR HAD SEIZED DUE TO THE IMS (INTERMEDIATE SHAFT). CAR HAD APPROX 34K FOR MILEAGE. CONTACTED PORSCHE AMERICA AND WAS BASICALLY TOLD THERE WAS NOTHING THEY COULD DO. AFTER RESEARCHING ON THE WEB, THIS APPEARS TO BE A PRETTY COMMON PROBLEM WITH THE 97-99 BOXSTERS. THE COST TO REPLACE THE MOTOR WITH A USED MOTOR WAS APPROX 9K AND THEY WOULD BE USING THE SAME TYPE OF MOTOR WITH THE SAME DESIGN FLAW. THE CAR HAS BEEN TAKEN TO THE SALVAGE YARD AND WE ARE OUT QUITE A BIT OF MONEY. *TR”
