What owners report

  • Some owners report the engine entering "limp mode" and dropping to 20 mph on the highway shortly after purchase, with a drivetrain malfunction warning.

  2. NHTSA 24V288000Apr 24, 2024Airbags5,761 vehicles

    Air bags:side/window

    BMW of North America, LLC (BMW) is recalling certain 2014-2015 2 Series Coupe (228i, 228i xDrive, M235i), 3 Series Sedan (320i, 320i xDrive, 328i, 328i xDrive, 335i, 335i xDrive, M3, 328d, 328d xDrive), 4 Series Coupe (428i, 428i xDrive, 435i, 435i xDrive, M4), and 2015 4 Series Gran Coupe (428i, 428i xDrive, 435i, 435i xDrive) vehicles.
