BMW has a great reputation among motoring enthusiasts, yet the brand has failed to impress owners responding to our Driver Power survey in recent years. Safety is beyond refute, with plentiful active and passive kit to help protect occupants and pedestrians. 

BMW 4 Series reliability

The BMW brand could only manage 27th out of 30 manufacturers in our 2020 Driver Power survey, beating only Mercedes, Vauxhall and Dacia. Audi managed a slightly better result, coming in 21st.

Running costs were deemed too expensive and owners weren't impressed with interior or exterior design - issues the contentiously styled 4 Series may only exacerbate. More pressingly, around 20% of owners reported at least one fault within the first 12 months.


It's not yet known if the 4 Series will get its own Euro NCAP crash-test rating, but the virtually identical 3 Series has already scored the full five stars, with an impressive 97% score for adult occupants. BMW includes autonomous emergency braking and lane departure warning as standard. An optional Driving Assistant Professional pack can steer the car and keep pace with traffic on multi-lane stretches of road.
