I had PCM/xm radio issue a few months back.
My local porsche dealer quickly resolved since i'm still under warranty.

Today, I received notification through mycarfax that my CTT had an open recall for the XM radio.

For those who had XM issues where the radio kept cutting out and rebooting, check to see if you are included in the voluntary recall.

The fix is a pretty straight forward PCM update. At least that resoled the issue i was having.

 

Same topic, slightly different issue.

For those with early 2015 models that had the XM missing from their PCM. Porsche just offered me the option to retrofit XM or extend my SiriusXM subscription. I chose the latter and they paid for 3 years of service for me.

 

I was wondering how that specific issue turned out.
Good news.....and certainly sounds at least fair.
