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.

My 2004 MINICooper S has 48,000 miles. The transmission has gotten so bad that I cannot change gears without great difficulty. I have read numerous reports online about power steering pump failure, brake failure and a host of safety issues with the cooper. I think this car needs to be evaluated for safety issues. Thanks, karen

problem #2

For absolutely no reason the manual transmission failed and locked up causing me to loose control of the vehicle at 40mph. No injuries or damage to the vehicle as I was able to control the slide. However I have spoken to both dealer and manufacture and they both admit the transmissions in these vehicles both automatic and manual are weak and can cause failure at any speed which will result in lockup of the front tires. Numerous reports from other MINICooper owners show the same. The transmission was replaced in this vehicle 3 years ago for the same problem. Now it needs replaced again. The only repair is to put a rebuilt unit in place with the same weak gears. MINIno longer warranties the repairs as of 2008 because of the problems. I got lucky but I carry my 3yr old son with me most of the time and this does not feel like a safe vehicle considering out of nowhere with no warning this failure could occur again. Both MINIusa, BMW have been very unhelpful in the matter unless I'm willing to pay over $1000 to have it towed to a MINICooper dealer just to have it looked at.
