Tail lamps are prone to hairline cracks difficult to see, when driven in rain or car wash tail lamp floods and causes electrical system to short circuit resulting in death or accident in inclement weather due to low visibility.

Engine stalls when stopped if not in sport mode. Electronic gauge display for oil level is confusing and shows low oil level in green, causing the user to add oil when it is full. Steering rubs and knocks when turning.

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.

TRW Automotive Inc. Airbag Control Unit (Part No. 218737-124 RI; Serial No. 11050089RI; Produced: April 20, 2015) was equipped in 2016 Porsche Cayman VIN [XXX] by Porsche (Vehicle Production Date: June 29, 2015). In 2019, TRW recalled the aforementioned ACU in NHTSA 19E-043. In 2019, in response to the TRW recall, Porsche recalled 2016 Porsche Caymans in NHTSA 19V-533 but Porsche & the NHTSA failed to include 2016 Porsche Cayman VIN [XXX] (Vehicle Production Date: June 29, 2015) from this recall by setting an incorrect production date bracket starting at July 8, 2015 which is at least 9 days too late. The ACU failed during normal operation of the vehicle on February 1, 2020. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

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 ENGINE BUT THEY PUT THE SAME PART NUMBER THAT FAILED BACK INTO THE CAR. THERE HAS NOT BEEN AN ENGINEERING REVISION TO THE PART, AND ANOTHER FAILURE IS POSSIBLE.
