The 2009 BMW X5 has 4 recalls, the most serious being a driver's airbag inflator that can rupture during deployment and send metal fragments into the cabin, posing a serious injury risk to the driver and passengers.
The heating element inside the crankcase ventilation valve can short and overheat, creating a fire risk both while the vehicle is moving and shortly after it has been parked. On the braking side, a vacuum pump that assists with braking force can leak oil into the connected hose, reducing brake pedal response and extending stopping distances. One recall applies only to the diesel xDrive 35d variant: the bolt securing an engine belt idler pulley can loosen and eventually break, causing sudden loss of power steering and making the vehicle significantly harder to steer.
