BMW to recall 30,265 X5 luxury SUV over faulty brake vacuum pump

German automaker BMW is recalling 30,265 of its popular X5 luxury SUV in the US over a brake vacuum pump oil leak that can hinder the braking efficiency of power brakes.

The recall covers model-year 2007 to 2010 versions of the X5 made between 12 September 2006 and 18 March 2010, according to a filing with the National Highway Traffic Safety Administration (NHTSA).

BMW said the "brake vacuum pump may leak a small amount of lubricating oil into the vacuum hose, which could result in contamination of the brake booster."

BMW added that the "loss of power assist braking could occur," which "could increase stopping distance and lead to a vehicle crash."

The carmaker said that it discovered the problem when warranty claims increased.

BMW said that no reports of crashes or injuries were reported.
