BMW X5: Steering
Affects BMW X5 · 2009–2012 — about 6K vehicles.
The hazard
On certain BMW X5 xDrive35d (diesel) vehicles, the engine belt idler pulley bolt could loosen and/or break. As such, the belt may become detached, resulting in a sudden loss of steering power assist. A vehicle experiencing a loss of steering power assist would revert to a manual steering mode which would require greater driver effort, especially at low vehicle speeds. This could ultimately result in a crash causing property damage and/or personal injury. Correction: Dealers will replace the idler pulley bolt and tighten with a revised torque procedure. A thread locking compound will be applied to the replacement bolt.
