SUV pair could be affected by brake failure, with just under 400 units included.

BMW Australia has issued a recall for the 2018 model-year X3 and X4 crossovers over concerns of a fault with the braking system.

The manufacturer reports that "there is a possibility of air being trapped in the hydraulic braking system", which can cause the rear brake circuit to fail, or in "extreme circumstances" the brake pedal may "travel to the floor".

If the condition occurs, this poses a hazard to the driver and other road users.

All 396 affected X3 and X4 units were available for sale from 15 April 2018 through 27 June 2018 – a VIN list for these vehicles is available here.

Owners of the recalled SUVs will be contacted directly by BMW Australia or a BMW dealer. Customers are advised to contact their local dealer, or the company's customer care line on 1800 813 299.
