A model year younger than 3 years is too early to compare, so it is left out of the years named as having the fewest or the most complaints. Recalls are a separate count. The numbers are for the US-market Porsche 718 Cayman. How we count.

Recall 16V-946 covers certain 2017 718 Cayman, Cayman S, 718 Boxster, and selected 911 models: the seat-mounted side air-bag inflator initiator may fail to ignite in a crash, so the side air bag will not deploy.
