Hi, have been experiencing same issue, now in the shop for the third time. Long story short--it happened first time on the highway--loosing power steering and throttle power is not fun at 60mph. That was around 2000 miles. Dealer service said there was a connector that had loose pins behind the firewall passenger side but i could not get any more details. It happened again around 12,000 miles, now just happened at 16,000. Fortunately this time i was only reversing out of my garage. I took a video of the dash while it was happening. My dealer has it now but of course never seen/heard anything like it. So if anyone has had this issue and found any fixes, would appreciate to hear about it. I will ask the service guys to check the CAN connector behind the A-pillar as mentioned in Albertabackroad's reply.
