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?

Two separate instances of fuel line failure and fuel leak in the engine compartment. The first in March 2024 and the second in September 2025. The situations both resulted in fuel leaking on top of the hot engine components. Repair requires removal of the engine and transmission. In 2024 repair time was 9 weeks, in 2025 - 3 weeks. In the first case service was covered under warranty, the second partially covered by extended warranty. Repair costs approximately $6,000 per occasion. Leaking fuel on a hot engine clearly created an unacceptable hazard. The vehicle was serviced, and the defect confirmed, at Porsche of Fort Myers (Florida) on both occasions. Evidence of the problem was identified via fuel smell only - no warning messages in the vehicle occurred.

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
