Porsche 718 Cayman
2016–2025
NHTSA has 6 open investigations on this vehicle right now.
Data Availability
Milemark has classified only 29 NHTSA complaints for the 2016–2025 Porsche 718 Cayman. This limited dataset does not indicate the car is reliable—it likely reflects the Cayman's lower sales volume and the fact that Porsche owners may resolve issues through dealers rather than filing federal complaints. Drawing broad conclusions from such sparse data would be misleading.
What We Know From Recalls
Porsche has issued 7 recalls for the 718 Cayman, primarily addressing airbag components (including side airbags and the restraint control module) and one fuel system defect. While recalls affect all manufacturers, buyers should verify any used Cayman has completed these safety campaigns.
Technical Service Bulletins
Porsche has published 607 TSBs for this generation—an unusually high number that suggests the factory has documented numerous fixes, updates, and known issues. Reviewing TSBs applicable to your specific model year can reveal common problems dealerships already know how to address.
Owner Watch-Outs
Among the few complaints filed, airbag and restraint issues dominate (34% of reports), though most are recall-related. Engine concerns appear sporadically—oil consumption, stalling, and internal engine issues—but sample sizes are too small to call these systemic. Two fuel pump complaints and isolated reports of water leaks and timing chain issues exist, but no clear pattern emerges.
How to Research Further
For any used 718 Cayman, get a pre-purchase inspection from a Porsche specialist, check the VIN history for open recalls and service records, and consult model-specific forums like Rennlist or 6SpeedOnline where owners discuss real-world experiences not captured in federal databases.

Complaint trends by era
← All yearsClick a window below to see complaint data scoped to just those years.
2016–2019 models account for the most complaints on record — 76% of 29 classified.
Year-over-year complaint volume
Complaints filed per individual model year, not blended into 5-year bands like the chart above — hover a bar for exact numbers. Recent model years show fewer complaints mainly because they've been on the road less time.
5-year windows, not manufacturer generations — this database doesn't have reliable platform/redesign data to draw real generation boundaries from. Recent model years show fewer complaints mainly because they have been on the road less time, not necessarily because they're more reliable — read this as complaint volume and mix by era, not a reliability trend.

From owner-filed complaints to NHTSA, not independently verified. Federal mileage reporting on recent complaints is sparse — see methodology. Cost ranges are national estimates from book labor hours and parts pricing, not this vehicle's actual repair history — they don't account for your location or shop type.
