The 2014 Mercedes-Benz B 250e has 3 recalls, with the most serious risks being an electric powertrain that can shut down without warning and strand the vehicle in traffic, and a driver airbag that can deploy on its own.
The powertrain shutdown is caused by a communication fault within the electric drive system, which can cut power entirely and leave the car unable to move. A stalled vehicle in moving traffic raises the risk of a rear-end collision. The airbag concern is separate: the driver airbag can deploy unexpectedly without a crash, which can startle or injure the driver and cause a loss of control. The third recall involves the emergency call system, which uses a software fault that can cause it to report the wrong date, time, and vehicle location when an emergency call is placed. If first responders receive incorrect location data, they may take longer to reach the scene.
