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 is yet to test the BMW X4, and it’s more likely that the X3 will be tested first. In fact, the likeliest outcome is that the X4 will be covered by the X3’s score, as it’s essentially a body variation of that model like an estate compared to a hatchback.
In terms of reliability, both the X4 and X3 are too new to have featured in the 2018 Driver Power survey, so it is hard to draw any firm conclusions. However the brand as a whole had mixed results in the survey, finishing 21st place overall out of 26 brands and behind both Mercedes and Audi. Over 25% of owners reported a fault with their car in the first year of ownership, while both build quality and exterior design failed to receive much praise. Running costs, practicality and infotainment were plus points for survey respondents, but it remains to be seen how newer models like the X4 perform.
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. The BMW Service Inclusive cover is available for the X4 at a price of around £400, which should provide a saving, although this only covers a basic service and does not reduce the cost of consumable parts outside of the service schedule.
