Hi, yes it does sometimes. I can go to the car in the morning and I have message in the MFD saying infotainment system is switched off and main infotainment screen in the dash is blank. I try and turn it on with left hand knob on the infotainment and nothing happens. I drive the car in the day and park up. When I return, sometimes, the infotainment main screen is alive and well when I start the car and I can access all the functions of driving data, sat nav, etc. Cheers,
