BMW X4 review - Reliability and safety
There’s a high standard of safety equipment across the range, but the X4’s reliability is yet to be proven
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 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 makes 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 a full five stars.
The X4 didn't feature in our Driver Power customer satisfaction survey, although the X3 finished 49th out of 75 cars. BMW itself was voted into 27th place out of 30 manufacturers, with owners saying their BMWs could be more reliable, and are quite expensive to run and maintain.
The X4 comes with a standard BMW warranty which is for three years from the date of first registration and unlimited mileage, which is the same as offered by Mercedes but superior to that of Audi, which is limited to 60,000 miles within the first three years.
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.
