Affected Cars

RepairPal Expert Overview

Our Quick Take:

On X5 models equipped with a diesel engine, the vehicle may unexpectedly lose power steering due to an engine drive belt issue.

What Should You Do?

BMW will notify owners of affected vehicles during January 2013. An abnormal engine noise may develop prior to failure of the power steering or there may be no symptom related to the recall. If you don't receive notification and you feel you should have, please contact your dealer. It’s helpful to have your vehicle identification number (VIN) handy when you call.


The engine drive belt has a device called an idler pulley that helps to keep the belt properly aligned with the power steering pump. The bolt that secures the idler pulley may come loose, causing the drive belt to fall off and power steering assist will be lost. If this occurs, you will still be able to steer your vehicle, it will just take much more effort. Your BMW dealer will replace and properly tighten the idler pulley bolt.
