Summary Verdict
The 2002 BMW X5, while offering a premium driving experience, is a vehicle that requires diligent maintenance and awareness of its common issues. The engines, particularly the V8 variants, can be prone to significant oil and cooling system leaks, with the V8s also having potential timing chain guide concerns. Transmission issues like harsh shifting are not uncommon. Electrical gremlins, such as window regulators and ABS modules, and interior component failures like pixelated displays, are also frequently reported. Owners should budget for potential repairs, especially concerning the cooling system, oil leaks, and electrical components, to maintain the X5’s reliability and performance.
