Chronological view of owner reports
The digital dash, which shows my speed, mileage, engine temperature, rims and fuel level goes blank. Then comes on for a few seconds and goes dark again. Vehicle only has 43k miles. MB dealer said this is not uncommon condition with the 2018 mb e400. Car is not safe to drive. MB dealer wants $6,100.00 to replace the unit. A software reboot will not work.
Alternator failed on my E400 cabriolet 23,000 miles resulting in car shutting down while engine running. Required a tow to dealer service area, 35 miles away.
The back-up camera failed while in the middle of reversing. Screen went completely black and unresponsive. Putting the car in Park then back to Reverse didn't work, screen still black. Tried turning off the car and turning it back on, screen still black and no back-up camera when I put the car in Reverse. I tried turning on / off the infotainment system and no change, screen still black. Later in the day when I got back in the car, the screen came up MUCH slower than usual, but did eventually come back up. This has happened multiple times and I've taken it to the dealer multiple times for this, but they've not been able to fix it.
Backup camera does not work sometimes. A picture of the camera with a slash mark across it comes up on a black command screen. This is a big safety issue when I back up
