As the X4 is likely to be used as a family car, safety remains a priority, and this is reflected in the generous provision of safety systems. Autonomous emergency braking (AEB) is fitted as standard across the range, and this can be supplemented with the optional fitment of active cruise control and lane-keeping assistance.

The optional Dynamic Safety system adds pre-emptive safety measures such as tightening the seatbelts if it determines that a crash is imminent, and can apply the brakes if an accident occurs. Euro NCAP produced an assessment of both the X3 and X4 in 2017, awarding both its maximum five-star rating.

The X4 didn't feature in our most recent Driver Power customer satisfaction survey, while BMW itself came 21st in the best car manufacturers rankings – down from 16th in 2022. BMW owners who took part in the survey have said their cars could be more reliable, and are quite expensive to run and maintain.

Warranty

The BMW X4 comes with a three-year warranty, with no mileage limit for that period. Mercedes offers identical levels of coverage for its cars, while all new Audis get a three-year/60,000-mile factory warranty.

Servicing

Another significant factor in running costs of the X4 will be servicing and parts replacement, although the BMW Pay Monthly Service Plan allows you to spread the cost of scheduled maintenance.
