This page covers 4 recalls and 19 owner complaints for the 2010 BMW X5 Sav.
For the 2010 BMW X5, the heaviest concentration of complaints centers on the engine and fuel system. Owners frequently report sudden power loss while driving, sometimes accompanied by the engine shutting off entirely, which also kills power steering and brake assist. A recurring theme involves the twin-turbo system, owners describe repeated turbo failures causing sluggish acceleration and a dangerous lag when trying to get up to speed from a stop. On the fuel side, multiple owners describe what appears to be water intrusion near the fuel injectors leading to electrical shorts and complete loss of power. A handful of complaints also reference the drive belt and idler pulley failing, with one pattern involving the battery warning illuminating before the engine cuts out. Airbags account for the third-largest complaint category, though the reports there are fewer and less consistent in their described symptoms.

By System
The 2010 BMW X5 has 4 recalls, the most serious being a driver's frontal airbag inflator that can rupture in a crash and send metal fragments into the cabin, posing a serious injury risk to the driver and passengers.
A second high-priority issue involves the crankcase ventilation valve heater, which can short electrically and overheat, raising the risk of a fire while driving or shortly after parking. On the braking side, a recall affecting 8-cylinder models covers a brake vacuum pump that can leak oil into the brake booster hose, reducing power-assisted braking and extending stopping distances. There is also a steering concern on diesel xDrive 35d models: an engine belt idler pulley bolt can loosen and break over time, causing sudden loss of power steering.
