Tl- the contact owns a 2003 Mini Cooper S. The contact stated that while operating the vehicle at low speeds the steering wheel required more afford to turn. While inspecting the vehicle the contact discovered that the power steering fluid had leaked from the power steering fluid reservoir. The cause of the failure was not diagnosed or repaired. The manufacturer was not notified. The failure mileage was 136,000. Jft.
Steering fluid continuously leaks - replace hydraulic hose twice - known defect - Mini refused to fix for free engine cooling - fan runs after shutoff continuously - known defect - Mini refused to fix for free electrical - doors, windows, sunroof fire off on their own while car is moving and when is parked. Will do this at highway speed or when sitting outside (rain or shine) - car unlocks itself and windows all open up -known defect - kind of distracting at highway speed -Mini refused to fix for free. Dealers will not fix these issues unless you make them recall vehicles with multiple small problems ( not just one big problem) - this model has 73 tsbs that dealers charge you to fix even though the problems are known and dangerous issues. In my mind, many small problems can be more dangerous than a few big ones - steering, door locks, cooling - not good. This is an old car but these problems are old too - known tsbs should not be subject to warranty time frames, they are still dangerous after the warranty expires. When these cars are routinely serviced, these known/dangerous issues need to be corrected or the cars should be taken off the road. I used the date of the last incident, not the first one. Thank you.
The steering on my '03 Mini Cooper Started making whining/ groaning noises that were not the normal steering noises. The steering has limited power boost, sometimes near normal, other times almost no boost. The steering doesn't return to straight as it used to. After making a right or left turn, the car keeps trying to turn the last direction steered. With effort, I can hold the car straight, but it pulls noticeably the last direction turned. The electric steering motor groans, changing speed up and down, even when the car is not moving. All fluid levels are normal and there are no leaks or drips of any fluid. The power steering fan and radiator cooling fan are operating correctly. The steering effort is not consistent. Sometimes at expressway speeds, as well as slower surface street speeds, the steering stiffens up where it requires much effort to control, then minutes later, will go back to normal boost levels. This often happens when negotiating lane changes or expressway ramps with what should be a steady rate turn. An independent mechanic states the electro- hydraulic steering pump is causing these issues and that BMW is aware of this problem.
