Reliability snapshot
The F15 X5 is a refined third generation. Common items are cooling-system components (water pump, thermostat, hoses), the oil-filter-housing gasket, and on the turbo V8 (N63, revised in this generation) continued attention to oil consumption and cooling. Six-cylinder N55 petrol and N57 diesel cars are dependable. Electronics and comfort features are generally reliable; routine cooling and gasket maintenance keeps the F15 in good health.
