Cayenne 3.2L V6

  • Automatic transmission
  • 174,000 miles

PORSCHE PCM reboot is reported a lot on the web - there is a lawsuit or maybe 2 regarding updates from Sirius XM causing failure of Porsche computer. The car continually reboots until battery is damaged.

My mechanic cannot get it to stop - so my fix will be to disable the PCM and use the car without it until a fix can be found.
