UNKNOWN OR OTHER
Rear axel carrier side section fractured in half. This can lead to loss of control of the vehicle when driving. Recall was issued for some models/years with specific batches, but mine was not included even though it’s the same issue.

AIR BAGS, UNKNOWN OR OTHER
Porsche dashboard leather has strunk and separated from the main dashboard. My understanding is that in the event of an accident, this could interfere with the airbag's ability to deploy correctly. A Porsche dealer has reviewed but was unable to repair it. The next step would be to replace. I've discovered this is a very common issue with Porsche vehicles from model years similar to this one.

SERVICE BRAKES
On the freeway the brakes began pressing themselves, lifting the pedal had no impact on the brakes being applied. I had to shift into 3rd gear and floor it to move off the freeway safely. The wheel weights fell off the wheels the brakes were so hot I had to keep away from the wheel. The tire was damaged from the heat and the sidewalls began to form cracks. It looks like this is a BRAKE BOOSTER failure as I have now read several people reporting the fix for it.

ENGINE
The Cayman S model with V6, 3.4L motor, commonly referenced as a 9A1 motor had been self destructing with increasing amounts of metal slivers/chips found in the drained oil, oil filter and oil filter housing. The in-warranty Porsche dealer "installed oil" was first inspected by my shop at 27,031 mi - alarmingly metal was found, PIC attached. Metal was non magnetic, appearing to be aluminium. Subsequent oil/filter inspections found the metal volume to be significantly increasing, PIC attached, putting the motor at risk of self destructing. Car was parked with only 29,509 mi in fear of having the motor blowup/lockup while driving at highway speeds. It would have the potential of stopping abruptly or locking up the rear wheels putting the car in a spin, possibly causing a crash. Risky. Without taking the motor out and disassembling, professional opinion and speculation indicates possible early main crankshaft bearing or rod bearing failure. Motor needs replaced (estimates from $25,000 to $45,000 depending on damage and whether a dealer or independent does the work.) The vehicle is currently parked and taken off the road. Too expensive to fix. Porsche North America offered no investigative or repair support because it is out of warranty. Disappointing customer support, with this being my fourth Porsche. Isolated incident or have others found a similar problem ????

POWER TRAIN
The contact owns a 2015 Porsche Cayman. The contact stated that the vehicle was taken to the dealer for the rear housing axle carriers repair under NHTSA Campaign Number: 21V679000 (Power Train). However, upon picking up the vehicle, the rear suspension was unstable and drifted all over the road while driving. The contact was able to drive to his residence. The vehicle was taken back to the dealer who inspected the vehicle and completed a torque adjustment however, the failure persisted. The dealer was notified but did not provide any assistance. Additionally, the contact stated that the vehicle had not experienced a failure prior to the recall repair. The contact also stated that the engine was located at the rear of the vehicle, which presented a severe potential risk to safety. The vehicle was not repaired. The manufacturer was notified of the failure and a case was opened. The contact was awaiting a call back from the manufacturer. The failure mileage was approximately 40,000.

FUEL/PROPULSION SYSTEM
Fuel tank is rubbing against the body causing visible rub marks on the plastic tank itself. This is caused by foam pads either being misplaced or not installed at all from the factory. Porsche themselves have a TSB on it (SB-1403), but they will not handle the fix outside of warranty. This seems like a major safety issue where a plastic component holding flammable fuel is rubbing against the metal body and causing a potential failure point where fuel can leak onto hot components. Porsche has stated this is not a safety issue, but I cannot see how that is possibly the case. Many others online are facing the same issue and are getting quotes of $2k USD for the fix to be carried out. Please look into this as I do not feel safe driving my car knowing that the fuel tank can rub itself to failure at any point.

ENGINE
The vacuum pump (Porsche part number 9A1-110-090-02) cover retaining screws vibrated out causing the cover to damage the fuel lines and causing an engine oil leak. The fuel and oil were ignited by the exhaust or stray spark cause by the vacuum covers rotation and hitting other metal objects. This vacuum pump provides vacuum to the brake booster and during the event drastically reduces the ability of the car to stop. The car was quickly consumed by fire (30-45 seconds) and I received very minor burns to my left arm exiting the car (mid-engine so the flames were coming out from under the drives side rear tire). I no longer have the car or parts but do have a lot of photos of the damage

ENGINE
The vacuum pump retaining screws vibrated out, causing an oil leak and reduced functionality of the braking system. This is the second 2011 Porsche Cayman S that I have owned to have this problem. The first cause a fire and I received minor burns from the incident. Fortunately this time no fire was caused and the vehicle is repairable. Please see NHTSA tracking number 11430927. I also spoke with a Porsche mechanic and was told he had seen this failure on several Porsche Cayman. I have not had the vehicle repaired yet, but will document the repair and retain the parts for inspection if needed.

VERY DANGEROUS IF THIS HAPPENS IN TRAFFIC AND YOUR LINKAGE FAILS WHILE SHIFTING AND YOU ARE NOW NOT IN ANY GEAR. *BF *TR CONSUMER STATED WHILE PULLING INTO THE DRIVEWAY THE VEHICLE ACCELERATED AND HIT THE GARAGE, AIRBAG DEPLYED.*JB

IGNITION COIL FAILURE ON CYLINDER #3 DUE TO NO HEAT SHIELD BETWEEN COIL & CATALYST WHICH IS SITUATED JUST BELOW THE COIL. THIS RESULTED IN SUDDEN LOSS OF POWER AND MISFIRES OF #3 CYLINDER. MECHANIC STATES THIS PROBLEM WILL HAPPEN AGAIN UNTIL A PROPER HEAT SHIELD IS INSTALLED BETWEEN THE COIL & THE CATALYST. I WAS IN TRAFFIC AT THE TIME ON A FREEWAY AT A SPEED OF 65 MPH.

POWER TRAIN
DRIVING AT HIGHWAY SPEEDS (55-60 MPH), ATTEMPTED TO DOWNSHIFT DUE TO TRAFFIC AND THE MANUAL GEAR SHIFT LEVER DID NOT RESPOND. IT WAS COMPLETELY LIMP AND SEEMED DISCONNECTED FROM THE SHIFTING ACTION. LUCKILY I WAS ABLE TO NEGOTIATE THE VEHICLE THROUGH TRAFFIC, TO AN OFF RAMP AND INTO A SAFE PARKING SPOT. HAD THE VEHICLE TOWED TO THE NEAREST DEALERSHIP AND WAS INFORMED THAT THE SHIFTER CABLE HAD BROKEN. AFTER SOME RESEARCH I NOTICED THAT THIS IS A COMMON PROBLEM FOR THE PORSCHE CAYMAN, SO I'M REPORTING THIS AS IT POSES A SIGNIFICANT SAFETY HAZARD FOR DRIVERS OF THE VEHICLE AND THOSE AROUND THEM WHEN THIS PROBLEM OCCURS. OBVIOUSLY NOT BEING ABLE TO SHIFT INTO DIFFERENT GEARS WHILE IN ANY SORT OF TRAFFIC CREATES A RISK OF INJURY OR DEATH. THE MANUFACTURER IS AWARE OF THE PROBLEM AND HAS APPARENTLY DONE NOTHING TO CORRECT IT. THE REPAIR COSTS ARE ALSO STEEP -- IT COST ME $1,325 FOR THE CABLE TO BE REPLACED, AS WELL AS OVER $100 FOR THE TOW TO THE DEALERSHIP. MY VEHICLE HAS 65,000 MILES ON IT, BUT I HAVE READ OF INCIDENTS WHERE THIS OCCURRED ON VEHICLES WITH FEW MILES AND SOME REPORT IT HAS BROKEN REPEATEDLY. SO I WOULD LIKE TO REQUEST THAT NHTSA INVESTIGATE PORSCHE AND URGE THE COMPANY TO ADDRESS THE SAFETY ISSUE WITH A RECALL AND/OR REIMBURSEMENT FOR REPAIR COSTS. THANK YOU. *TR

I WAS DRIVING TODAY ON 4TH OF JULY AT 10 MILES AN HOUR OUT OF MY DRIVEWAY AND IT STOP ALL OF THE SUDDEN. ME, MY WIFE AND MY DAUGHTER PUSHED IT BACK INTO THE DRIVEWAY AS I WAS BLOCKING ONE WAY EGRESS FOR THE NEIGHBOURS AND THEIR POSSIBLE GUESTS FOR JULY 4TH. I DO NOT KNOW WHAT FAILED, I GUESS IT IS SHIFT CABLE BROKE. IF I WAS DRIVING ON THE BUSY HIGHWAY, THIS FAILURE COULD KILL ME AND OTHER DRIVERS WHO COULD BE DRIVING BEHIND. JUST BOUGHT THE CAR ON 5/31/15 FROM DEALERSHIP AFTER LEASING IT FOR 3 YEARS. WHILE PUSHING THE CAR BACK I HURT MY BACK EVEN MORE THEN IT WAS PRIOR. 7/4/15

ENGINE, VEHICLE SPEED CONTROL, POWER TRAIN
WHILE ON A PUBLIC FREEWAY, I HEARD A LOUD SNAP AND THE SHIFTER CABLES BROKE IN AN ATTEMPT TO SHIFT INTO 4TH GEAR, LEAVING THE VEHICLE STUCK IN 3RD GEAR. VEHICLE WAS IN A GRADUAL ACCELERATION AT THE TIME OF FAILURE ENTERING THE FREEWAY. THIS RESULTED IN AN UNSAFE CONDITION, AS INITIALLY IT WAS NOT APPARENT WHAT HAPPENED AND THE ENGINE OVER REVED CAUSING UNINTENDED ACCELERATION. EVENTUALLY IT BECAME APPARENT THAT THE VEHICLE WAS STUCK IN GEAR. SPEED CONTROL WAS IMPAIRED, AND VEHICLE WAS IN AN UNSAFE, DIMINISHED CONTROL CONFIGURATION. THIS ALSO CAUSE LOSS OF STEERING CONTROL FOR A MOMENT AS THE TAIL OF THE CAR SWEPT OUT. FORTUNATELY THERE WAS MINIMAL TRAFFIC WHICH ALLOWED THE SITUATION TO BE HANDLED. HAD THE TRAFFIC BEEN HEAVIER THIS MAY NOT HAVE BEEN THE CASE. THIS ALSO MADE FOR AN UNSAFE SITUATION TRYING TO SLOW THE CAR DOWN AND MOVE OFF THE FREEWAY. VEHICLE IS A MANUAL TRANSMISSION, SO EVENTUALLY REDUCED THROTTLE AND USE OF THE CLUTCH ENABLED A SAFE OUTCOME. REPLACEMENT OF THE SHIFTER CABLES WAS REQUIRED TO RESTORE VEHICLE TO OPERATIONAL CONDITION ( AFTER TOW TO A REPAIR LOCATION). UPON SEARCHING FORUMS, THIS IS AN ISSUE WITH THE DESIGN OF THE SHIFT CABLES. A PLASTIC SHEATH CAN MOVE OUT OF ALIGNMENT CAUSING METAL ON METAL WEAR OF THE CABLE UNTIL IT SNAPS.
