I have almost a year old MX p100d and I have noticed that lately very often I get "systems are powering up" message. Sometimes it clears within a few seconds, but sometimes it takes much longer. I've been kinda ignoring it, but today I had a scary incident while I was waiting for my son in school car line. I was waiting for a while, so the car turned off and both screens went black. When it was my turn to move, the car wouldn't wake up- both screens remained black, pressing brake didn't help. I tried doing a steering wheel reset- nothing. I couldn't even use my blinkers to show people behind me that my car was dead. After about 2 minutes the car somehow came back to life. What is this? Should I take it in? Any advice is appreciated.
