Vehicles Affected: Approximately 2,600 model-year 2014-15 Mercedes-Benz B-Class Electric Drive plug-in hatchbacks manufactured between Nov. 21, 2013, and May 26, 2015
The Problem: A communication error within the electric drive system may shut down the electric powertrain unit, temporarily immobilizing the vehicle and resulting in a loss of propulsion power; a vehicle stall in traffic increases the risk of a crash.
The Fix: Dealers will update the electric drive system software for free.
What Owners Should Do: Mercedes-Benz will begin notifying owners in December. Owners can call the automaker at 800-367-6372, the National Highway Traffic Safety Administration’s vehicle-safety hotline at 888-327-4236 or go to www.safercar.gov for more info.
