Engine And Engine Cooling Problems of Porsche Cayman

I received delivery of my vehicle this morning and put about 20 miles on it when I received an engine fault error and my vehicle check engine light came on while accelerating from a stop to about 15 mph before the issue occurred. I lost responsiveness and my engine was in “limp mode”. This occurred in traffic and I had to safely exit the roadway before calling roadside assistance to get it towed to the dealer. Odb error codes from a shop include: 2838-p0087 fuel rail system pressure too low - short to plus 10591-p0301 cylinder 1 misfire detected 10592-p0302 cylinder 2 misfire detected 10593-p0303 cylinder 3 misfire detected 851ch/34076 undocumented code.

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.

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 ????.

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.

I was going down hill in 3rd gear of a manual shift. The shift suddenly broke and I could not change the gear and had to pull over in a narrow road without any space for cars to pass by. It took Porsche 110 minutes to come a get the car. Lucky for me, I was about to enter a highway!.

Travelling in a straight line on a dry road at around 65mph, the vehicle's engine expired in a huge plume of coolant/oil. Flatbedded to a Porsche dealership, a technician using a boroscope found (according to the dealership) "scoring to #5 cylinder and evidence that a valve had hit the top of the piston. There was also a huge amount of metal debris in the oil filter. " this was a result of something failing in the engine, rather than the cause of the failure. The Porsche dealership did not care to determine the cause of the failure. I suspect intermediate main shaft (ims) failure. One year beyond certified pre-owned (cpo) warranty and $20k for a new engine.

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.

Intermediate shaft broke. Ims failure. Result is whole engine replacement.

Motor failed unexpectedly while accelerating, causing loss of power and loss of control. Mechanic inspection says that it was not my fault, as the failure occurred at 3500 rpm and there was no stress that should cause failure. No sludge found in engine, oil changes done on time. Failure necessitates a completely new motor at a cost of $16,000. After investigation, it appears that complete motor failure between 40-50k miles on the 2006 Porsche Cayman s is fairly common.

When I was driving the normally, the engine just blew. No over rev or shift miss. I brought the car to a dealer and was told that it seemed one bearing at the crankshaft failed. I've seen many similar engine blows for the same type of vehicles on the net so I'm wondering if this could be a design flaw. I expect NHTSA's investigation.

As I was accelerating for a merge, the car bucked and hesitated despite having my foot on the gas. I shifted gears and it was the same problem then there was an odd noise from the engine. I pulled off and the oil pressure warning light came on just as I stopped the engine. I had the car towed to the repair shop.
