2012 BMW X5 Sav

Complaints for the 2012 BMW X5 cluster most heavily around the powertrain and engine. On the powertrain side, owners report transfer case failures that result in sudden loss of power delivery to the wheels, and at least one owner describes a driveshaft snapping at relatively low mileage, leaving the vehicle immobile. Engine complaints center on the diesel variant's EGR system, owners describe a failed or leaking EGR cooler and non-functioning EGR valve, with symptoms including a diesel smell in the cabin and a check engine light. A separate engine report describes the motor seizing without warning while driving, with the vehicle having to be towed and no clear cause identified at the dealer. Steering complaints make up the third-largest category, though the reported volume is smaller. The EGR cooler failure and transfer case issues are the most consistently described problems across multiple reports.
