What's wrong, in plain English
The welded spur gear inside the front axle electric drivetrain on these vehicles may not have been welded correctly. A weld that was not done properly can leave the gear weaker than it should be. Over time or under stress, that weak weld can cause the gear itself to fail, affecting how the front axle drivetrain holds together and functions in the vehicle.
What you should do
Contact a Mercedes-Benz dealer, or call MBUSA at 1-800-367-6372.
The front axle electric drivetrain will be replaced free of charge.
