What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2015 Porsche Cayman, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Airbags
Reports naming the air-bag system — deployment behaviour, inflators, sensors and warning lights.
From owner reports, verbatim
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.
My door panels are delaminating around where the side curtain airbags are located. It has me concerned about driving the vehicle if I was involved in an accident.

Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.
From owner reports, verbatim
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 ????

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
