NHTSA recall 09V255000
Service Brakes, Hydraulic · BMW of North America, LLC
Details
What's wrong: The rear brake discs may not have been manufactured according to specifications. As a result, a reduction in braking performance at the affected rear wheel could occur.
Why it matters: In an extreme case, the affected rear brake disc could break resulting in a loss of braking at that wheel increasing stopping distances and the risk of a crash.
The fix: Bmw will notify owners and will repair the vehicles by inspecting the rear brake discs and, if necessary, replace them free of charge. The safety recall began on September 11, 2009.
