NHTSA defect investigations
Federal safety investigators have looked into a possible defect involving the 2017 Porsche 718 Cayman:
Desiccated Air Bag Inflator Rupture
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited.
What 2017 Porsche 718 Cayman owners say
Seat belts
I have a Porsche 718 Cayman [redacted] I purchase this vehicle October 16, 2020 with only 1,500 miles on the odometer from Porsche of Tucson 4690 E 22nd St, Tucson, AZ 85711. Purchase Porsche extended platinum warranty for 96/100,000 miles. My passenger side 3- point seatbelt will not retract back properly. This is definitely a safety issue for the passenger. I set up an appointment to have it fix with the Porsche of Tucson dealership. I was told that it would not be covered under the platinum warranty. The odometer mileage I have now on my Porsche 718 Cayman is 13,685. I believe it should be covered due to a safety issue and especially with low mileage on the Porsche 718 Cayman with passenger seat belt not retracting back it stays loose on the passenger when seat belt is on. …
Both headlights get foggy condensation driver side seat belt retractor lose and making rattling noise windshield wiper has poor contact with front windshield. Poor visibility on rainy day
