What owners report most
Engine and engine cooling
“THIS IS A VERY WELL KNOW IMS FAILURE ISSUE WITH PORSCHE BOXSTER WHICH CERTAINLY CALLS FOR A RECALL FROM PORSCHE. MY 2005 ENGINE WILL NEED TO BE REPLACED FOR 20K JUST BECAUSE OF THE VERY OBVIOUS DESIGN FLAW PORSCHE HAS IN ITS M96 ENGINES. I AM PRETTY SURE THERE HAVE BEEN NUMEROUS COMPLAINTS ABOUT THIS IN PAST BUT NOBODY HAS EVER HEEDED TO IT. I SINCERELY RECOMMEND SOME ONE TO PLEASE LOOK INTO AND ASK PORSCHE TO ACCEPT AND RECALL M96 ENGINES FAILING DUE TO IMS. ANY CAR EXPERT OR MECHANIC OR DEALERSHIP CAN VOUCH FOR THE DESIGN FLAW PORSCHE HAS. ITS POTENTIALLY FATAL TOO. I SINCERELY REQUEST SOMEONE TO LOOK INTO THIS COMPLAINT WITH UTTERMOST SINCERITY. *TR”

“WHILE I WAS DRIVING ON A CITY STREET AT ABOUT 30 MPH, MY 2005 BOXSTER STARTED MAKING A RATTLING NOISE, THEN COMPLETELY DIED IN THE MIDDLE OF AN INTERSECTION ON A CITY STREET WITHOUT ANY PRIOR WARNING. AT THE SAME TIME, ALL OF THE WARNING LIGHTS CAME ON. I WAS ABLE TO PUT THE CAR IN NEUTRAL AND COAST TO THE SIDE OF THE ROAD. CAR WAS TOWED TO MY MECHANIC, WHO STATES IT IS AN INTERMEDIATE SHAFT BEARING ISSUE/FAILURE. HAD I BEEN DRIVING ON THE FREEWAY AT HIGH SPEED, I MOST LIKELY WOULD HAVE BEEN KILLED. I AM THE ORIGINAL OWNER OF THE CAR, IT HAS 128,000 MILES AND RECOMMENDED MAINTENANCE IS ALL UP TO DATE.”
Power train
“TL* THE CONTACT OWNS A 2005 PORSCHE BOXSTER. THE CONTACT WAS UNABLE TO DRIVE THE VEHICLE BECAUSE THE IGNITION KEY WAS LOCKED INSIDE THE IGNITION. THE CONTACT TOOK THE VEHICLE TO A CERTIFIED MECHANIC WHO DIAGNOSED THAT THE TRANSMISSION FAILED AND NEEDED A CABLE ADJUSTMENT WITH THE TRANSMISSION AND THE KEY. THE CONTACT STATED THAT THE FAILURE WAS DIRECTLY RELATED TO NHTSA CAMPAIGN NUMBER: 03V004000 (POWER TRAIN); HOWEVER, THE VEHICLE WAS NOT INCLUDED IN THE RECALL. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 47,000.”
