4 Power Train problem

Failure Date: 03/03/2010

We have had our Mazda cx-9 since 2007. At 58,000 miles we noticed a "humming" noise. We took the vehicle into the Mazda dealership since it was still under warranty. We got the run around stating it was our tires; however, it turned out the front wheel bearings were bad. They replaced the bearings and one year later we are having to replace the rear bearings. Through research we are finding that Mazda has a service bulletin issued 2/1/2008 about the rear bearings. Basically stating the noise is from an improper shape of the abs sensor and this is only covered if there is still a warranty on the vehicle. My question is if they know this is a problem then why is this issue not recalled because a frozen bearing is and can be very dangerous. Mazda refuses to help replace our rear bearing since we are now at 74,000 mile and our warranty is out. All we keep getting is a run around by our local dealerships. We also have had problems with our driver side mirror. Mazda replace the mirror a few weeks after we bought of cx-9 but it still shakes.
