BMW is recalling more than 30,000 SUVs to fix an oil leak that can knock out the power-assisted braking.
The automaker is recalling X5 SUvs in the U.S. with the model years 2007 through 2010 produced between September 12, 2006 and March 18, 2010.
The company says a small amount of oil can leak from a brake hose and cause the power-assisted braking to fail.
Even though BMW says the brakes would still work, the problem could increase stopping distances causing a crash.
BMW says there are no reports of injuries or accidents and the company will replace a brake vacuum line hose for free.
The recall is expected to start later this month.
