One problem related to brake disc pads has been reported for the 2006 BMW X5. The most recently reported issues are listed below.
Brake pads wear out within 35,000 klm on BMW X5. Not covered under extended warranty and the average for performance brakes like these are suppose to be 50,000 klm. BMW will not replace the brake pads without replacing all 4 rotors at the dealership level. All other vehicles with performance brakes on sports cars have lasted over 50,000 to 90,000 without replacement of brakes. We're not hard on brakes if you take a look at our last 2 vehicles with performance style brakes on sports cars. . .
