I have a 2014 C2S Cab and today the PCM was constantly freezing and then rebooting when listening to music from my USB drive. What would happen is no response at all to buttons on the PCM or through the steering wheel on the TFT screen, then it shuts off and reboots from the Porsche logo. Each time it rebooted, it seemed to revert to what it was doing when I started the car the first time today.

The drive had been previously working fine, and when I removed the drive and listened to Sat Radio instead, the issue stopped.

I have a November '13 build, so presumably have the latest software.

Any one else experience anything similar?

Sounds like a trip to your friendly dealership is needed.

sounds like they need to re-flash the software. My 2009 Cayenne had a similar issue, turned out it was caused by a corrupt file downloaded from XM/Sirius.

I had exactly the same problem. The dealer did a software update and I haven't had the problem since July.
