Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. Notes: Power steering problems are a major issue with the 2004 Mini Cooper, with hundreds of owners reporting complaints to the NHTSA about their power steering suddenly failing while driving.

Some power steering failures have caused crashes & injuries. Average mileage at failure is well under 100,000 miles & the repair cost is over $1,000. Not good.

The contact owns a 2004 MINICooper. The contact stated that while traveling 35 mph, the power steering completely failed and the steering wheel seized.

Failed component 1: lower control arm bushings diagnosed at dealership as bad and oil leak is due to faulty O ring. Failed component 2: power steering total failure. Dealer stated this was due to poor design of steering pump fan (poor placement of the fan). Dealer stated there was a possible recall regarding power steering failure due to this poor design possibly pending. Work to repair these failed components has not been completed pending a dealer recall. The car is not drivable.
