This page covers 10 recalls and 270 owner complaints for the 2012 BMW X5.
Complaints about the 2012 BMW X5 cluster most heavily around the airbag/restraint system and the engine. On the restraint side, owners frequently report a "restraint system malfunction" warning light, with many tracing it to the passenger seat occupancy sensor failing, triggering alerts that the airbags or seatbelts may not function correctly. Engine complaints cover a wide range of symptoms: timing chain failures, loss of power or hesitation under acceleration, coolant leaks tied to water pump failure, and check engine lights appearing intermittently alongside other electrical oddities like flickering interior lights. Powertrain complaints, the third-largest group, tend to overlap with the engine reports and describe similar hesitation and power-delivery issues. The timing chain failures stand out within the engine category, with multiple owners describing the chain breaking without prior warning symptoms.

By System
The 2012 BMW X5 has 10 recalls, the most serious being faulty airbag inflators on both the driver and passenger sides that can explode and send metal fragments into the cabin, causing serious injury or death.
Multiple recalls cover these airbag inflators, with some filings targeting vehicles registered in high-humidity states and territories where the risk is elevated. On the fire and steering side, the power steering gear can develop a fluid leak that strips away steering assist and, if fluid contacts a hot engine or exhaust component, can start a fire. There is also a separate fire risk on xDrive50i and X5 M models, where a turbocharger circuit board can overheat. The drivetrain has two concerns: on xDrive35i, xDrive50i, X5 M, and xDrive35d models, water and debris can wear out the front driveshaft's universal joint until it fails and the front wheels lose drive power. On xDrive35d diesel models specifically, an engine idler pulley bolt can loosen and break, causing sudden loss of power steering. Finally, a small number of xDrive35i vehicles built over a two-day window in late 2011 may have a transmission that does not actually engage park even when the display shows it, leaving the vehicle free to roll away.
