DETROIT - BMW is recalling more than 30,000 SUVs to fix an oil leak that can knock out the power-assisted braking.

The German automaker says the recall covers X5 SUVs in the U.S. from the 2007 through 2010 model years. The vehicles were made between Sept. 12, 2006, and March 18, 2010. They have eight-cylinder engines.

The company says a small amount of oil can leak from a brake hose and cause the power-assisted braking to fail. Brakes would still work, but the problem could increase stopping distances and cause a crash.

BMW says it has no reports of crashes or injuries. The problem was discovered when warranty claims increased.

The company will replace a brake vacuum line hose for free. The recall is expected to start this month.
