In a year, this is my 3rd time having this issue, but this, on video, is the most agressive one: car doesn't start at all. The car has this behavior: when starting the car, the screen goes off (MEDIA NAV) then or it restarts by itself or it doesn't restart at all. If the car restarts, it restarts with the MEDIA NAV off, and nor sensor nor the AC system works. As you don't have screen, the rear camera is useless... so you go back to a 1970s car. Old style!
HAVE YOU HAD SOMETHING SIMILAR? The Renault/DACIA workshop is clueless.
