Summary Verdict
The 2006 BMW X3, while offering a premium driving experience, exhibits some common reliability concerns typical of European luxury vehicles of its era. The inline-6 engines, particularly the 3.0L, are generally robust but prone to oil leaks and cooling system issues. Transmission problems, especially with the automatic gearboxes, can be costly to repair. Suspension components like control arm bushings and shocks are also known wear items. Electrical gremlins, such as window regulators and ABS modules, can add to the ownership cost. Despite these potential issues, many owners find the X3 to be a capable and enjoyable vehicle when properly maintained, with repair costs often reflecting its luxury segment.
