Porsche 718 CAYMAN problems and owner complaints

THE VARIABLE VALVE TIMING ADJUSTER SPROCKET BOLTS HAVE A TENDENCY TO SHEAR UNDER HIGH LOAD. THIS IS A DOCUMENTED ISSUE THAT WAS ALSO COMMON IN SEVERAL OTHER PORSCHE MODELS OF SIMILAR PRODUCTION YEAR RANGES. THE VALVETRAIN LOSES TIMING, RESULTING IN A CATASTROPHIC ENGINE FAILURE WHICH DISABLES A VEHICLE. MY VEHICLE SUSTAINED SUCH A FAILURE AND THE CAR IMMEDIATELY WENT INTO "LIMP MODE." ALL THE VALVES ON ONE CYLINDER BANK WERE BENT. OTHER MODELS WERE RECALLED BUT THE CAYMAN AND BOXSTERS THAT CAME WITH THE 9A1 ENGINE WERE NOT. PORSCHE REPAIRED MY …

While travelling on the freeway on 7/30/23, I experienced a "low oil pressure, shut down engine immediately" warning. I pulled over to the shoulder and was unable to restart the car. It was towed to Porsche Carlsbad dealership where it is awaiting analysis by Porsche. The car has 4900 miles on it and is under the MFG warranty.

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 det…

The dealer reported a misfire. Upon detailed investigation and a bore scope, the inside cylinder lining had disintegrated and metal shavings were in engine oil. The motor needed to be replaced. This took 30 days to receive new motor. Upon installation, the gear shifting linkage failed, necessitating removal and replacement of these parts. The issues are ongoing at this time and I still have not had the car returned to me. It is still being repaired nearing 45 days in the repair facility.

The motor experienced a catastrophic failure causing the rod to blow through the top of the engine, cutting a fuel line and causing a fire. It was later determined and passed to me via unofficial sources that this was due to a manufacturing defect where the incorrect camshaft bearings were used on specific pistons. Via online and first account conversations, it seems this has happened at least 12 other times. Those vehicles which can be found online were complete losses. Via second hand conversations, Porsche technicians said this was the fir…

The passenger side (right rear) inside CV joint grease boot clamp failed and leaked grease. I discovered it while switching out Winter to Summer tires. I have included pictures. In researching the defect I found that it is a common occurrence with the Porsche 718 Cayman and occurs with low mileage. I believe the clamp was defective or not installed correctly during the assembly process. If I didn’t catch the leak it could have resulted in a drive axle failure and breakdown on the road endangering myself or other vehicles. My car is not tracked …

Windshield washer hose has snapped at the hood hinge which is preventing clearing of the windsheild of debris and obscuring forward visibility. This part was replaced by the dealer in 2016 during the first annual service for reasons unknown to me and has now failed.
