“Vehicle won't go into park, drive, neutral, or reverse when I push the button to tell it to. Vehicle's turn signals don't turn on when I move the handle up or down to try and turn them. It handle clicks as if it is turned on but blinkers do not turn on. Almost got hit by another car when this accrued because the blinkers didn't come on and the car didn't see that I was stopping. Very scary and dangerous since I have two small children.”
NHTSA complaint #10917923, filed 2016-10, 70,000 miles“As described above. Instead of blowing a fuse , fuse housing melted from fire and heat requiring replacement of the entire housing with all fuses and relays.

They do not want to accept their own service mechanic 's description of what happened. I am afraid this car has all the potential of bigger fire hazard and potential for accidents and deaths. …”

After struggling for 5 minutes trying everything from locking/unlocking opening doors turning key slowly it finally starts. This problem started a month ago and is becoming more frequent now. After reading numerous complains on forums I assume it is the esi (electronic system ignition) and it is an expensive fix so I called merc benz and complained and asked if there is a recall. …”
