Power steering issues: Mini Cooper Convertible 2005. The first evidence of my problem was when the electrical system seemed to be faulty. I replaced the alternator, and that fixed the car for about two weeks. At that point, I noticed a fan running a lot, and then found the battery dead on several occasions. Finally, I figured out that a fan was continuing to run--and I traced the noise to the power steering pump. I disconnected the battery, and then drove to the shop. They replaced the power steering cooling fan. This solved the problem for about three months. This weekend, I parallel parked in a tight space with a slight dip. I realized while parking that I suddenly had no power steering, but I thought it was because of the way I parked. It did not get better as I left. I muscled the car out of the space, and drove it to my local shop, where they told me that the fan still worked, that the fuses still worked, but that the power steering pump had failed. Had already read extensively about power steering pump failure issues when I heard the fan running in the first place. But. . . I thought after a few months that I was lucky to avoid the pump failure--in catching the fan first-- but it seems that many here have described. Exactly the same trajectory. I called Miniusa and a local dealer, and they refuse to help, because my car's manufacture date is a little under two months past the date included in the "extended warranty notice". This is ridiculous! it is exactly the same problem described in the recall, in every detail, and it is a safety issue. I am extremely lucky I was not hurt by it. I filed a formal complaint directly with Mini USA. If I felt it were for lack of maintenance, or normal wear and tear, I could accept that, but this car has meticulous maintenance, and records to back it up.
