You can bet your bottom dollar that it'll occur more frequently after the warranty expires!!!

OK maybe I'll reschecdule the appointment after the holidays.

I just hate going into the dealership now. Come in with one problem, leave with two. I have a mark on my otherwise like new leather, from last time they did work on it. (try to prove it was them however...)

All he said they were going to do is reflash the PCM. Its the same software so.....

Having the same problem and took it in twice. Flashed the PCM both times with no luck. Sometimes it reboots every 3 or 4 minutes and other times the PCM works perfectly. I was thinking it might be the hard drive going bad because you can actually hear the high pitched whine of the disk slowing down right when the system crashes and reboots. The only thing is that it's not consistent. Going to take it in for a third time. On a side note anyone with a panamera s having issues with launch mode not working consistently?

I've had my 2010 PTT for a couple of months. In that time twice the map view has said "Loading" or something to that effect for a long time on both the main screen and instrument cluster screen. Both times were right after I got the car but it hasn't happened since. Keeping my fingers crossed that I won't see it happen again.
