Mercedes-Benz dashboard display can go blank while driving high
In these Mercedes-Benz cars and SUVs, the infotainment computer can restart by itself while you are driving. When it does, the digital dashboard in front of the driver goes completely dark. You lose your speedometer and any warning lights, so you cannot tell how fast you are going or whether something else on the car needs attention. The dealer loads updated infotainment software at no cost to fix it.
