In the 2.5 years I've owned my 2015 Porsche Cayenne S e-Hybrid, I've had only two issues:
1. The electric charging filler door stopped opening; the dealer replaced the actuator under warranty.
2. The oil filler light quite commonly goes on, indicating that there's too much oil! I then have to take the oil filler cap off and wipe it down, then put it back on--the warning light goes off. But then it comes back several days or several weeks later. I find it difficult to believe that there really is too much oil in the engine. Does anyone have this same issue?
Other than these two issues, I've had no trouble whatsoever. I get the Cayenne serviced once a year (inspection, oil and filter change, fluid top-off, and tire rotation).
