Known issues on the 2014 B Electric Drive. The federal record holds three recalls for this hatchback. The most direct concerns the drivetrain: on certain 2014 B Electric Drive vehicles built within a specific production window, a communication fault inside the electric drive system could switch the powertrain unit off and leave the car briefly without propulsion, which dealers corrected with a software update. A second recall addressed certain cars whose driver air bag could deploy without cause, fixed by adding grounding to the steering components, and a third covered certain vehicles with an emergency call software fault that could send responders a wrong location. Of 21 owner complaints, 10 cite the power train and eight the electrical system. The manual's diagnostics, wiring diagrams and procedures cover these systems.
