This is caused by cracked solder joints on the PCB behind the info centre.

There's a relay on there and it cracks around the base, giving the info centre computer an intermittent, ripply power supply: which is just perfect to trip it on its face as shown. When you shut the car down the relay clicks which is enough to re-make the solder joint, until it heats up again in use and you're back to square 1 and Martian on the readout.

10 mins with the soldering iron sorts it out and whilst you are in there renew every electrolytic cap you can see.
