Porsche Cars North America, Inc. (Porsche) is recalling certain 2021-2023 911 Turbo S, 2022 911 Turbo, 2022-2023 911 GT3 Touring, 911 GT3, 911 Carrera 4 GTS, 2022-2024 911 Carrera GTS, 2023 911 GT3 RS, 911 Dakar, and 2024 911 Carrera T vehicles equipped with optional full bucket seats. The seat-mounted air bags may deploy unnecessarily during a crash.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“The fuel injection problem on cylinder 2 and 4 had injector electrical faults for the last two years resulting in reduced power warning. I finally took my car to the dealer for an analysis. After their analysis here is their statement on the service invoice: "Client state check engine light comes on and vehicle will run rough - Client scan for codes and had codes P0202 & P0204. Cylinder 2 and 4 fuel injector electrical faults. After updating DME software, clearing faults and test driving, mil illuminated again. Quoted fuel injector replacement. Due to the large amount of labor required for replacement, all 6 have been quoted to circumvent a potentially bad batch and to prevent a re-visit to replace any additional injectors at a later date." I had to pay almost $11,000 to replace "bad batch" injectors on a car that has only 13,455 miles. If they are "bad" injectors, is this a wider problem than my vehicle?”
“2021 Porsche 911. Consumer writes in regards to missing computer chip for proper steering.”
“THE SEAT BACK RELEASE ON BOTH SEATS IS VERY HARD TO PULL. ON THE DRIVERS SIDE THE STRAP BROKE FREE WHILE ATTEMPTING TO EXIT AND THE SEAT WOULD NOT RELEASE. THIS COULD BE A SAFETY DANGER IN A CRASH WHEN REAR SEAT OCCUPANTS WOULD NOT BE ABLE TO EXIT”
