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).

I went to my Porsche dealer. It turns out it's a simple software fix under warranty; the parameters for when the light goes on have to be widened so it won't go on anymore in a panic stop. All fixed!

As mentioned above, a software update fixes that. Here is the detail on the update:

Cayenne S E-Hybrid (92A)

Subject:
Engine oil change quantity

Information:
On vehicles with a conventional drive system, the fuel that gets into the
engine oil is evaporated by the high operating temperatures of the
combustion engine. However, this fuel might not evaporate fully due to the
comparably low temperatures of the engine in hybrid mode on the affected
vehicles.

If the combustion engine does not reach a higher operating temperature for a
long time, e.g. during frequent short trips, this can cause the oil level to
increase to such an extent that the oil level measurement will activate the
warning message "Oil level above maximum" in the instrument cluster.
However, the functional properties of the engine oil are always guaranteed.
