 I have a 2007 x5, ever since we purchase this vehicle, we had problems with the engine lights which the dealership told us is the battery problem, it has took them several times to fix the part for the battery but still having problem with battery draining either low or high. Since having the vehicle for less than 2 years, we must have gone to BMW for service no less than 10 times for problem such as peeling leather, broken front venting knobs, falling door panels, unworkable menu buttons and more. Will never buy another BMW vehicle in my life ever again
