There are 3 owner-reported fuel system complaints for the 2013 Porsche Cayennein NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Engine light came on and vehicle decelerated while making a turn in traffic. Based on the owners manual and code test, it comes up as a DPF issue. We could have been seriously injured had the oncoming traffic been closer to us or had someone attempted to follow me on the turn. When the car lost power, I could not accelerate to complete my turn. The problem has been duplicated by my husband who has some mechanical expertise, but the next step would be to take it to a dealer. It is available for inspection, but it is not safe to drive. The check engine light and the glow plug lamp came on at the same time. It happened once before on the interstate coming across I-80 on the interstate. In the middle of nowhere with no cell phone service, we were able to pull over, shut off and restart the engine which cleared the code for the rest of the trip. Then it didn’t do this again for nearly two months.
