While backing out of my driveway the right front ball joint separated and then the pulled wheel away from the vehicle, pulling the axle out. We had to remove the wheel, insert the axle and put the wheel back on before we could even move the car onto the tow truck.

The passenger front wheel disconnected from the lower control arm, resulting in immediate loss of control of the vehicle. Fortunately the vehicle was being driven thru a residential area at a low speed. Two months prior to the failure, the car had a front-wheel alignment, and the mechanic assured me that there was no detection of the imminent failure. I certainly do not wish to have this occur at highway speeds. I had both lower front ball joint/lower arm assemblies replaced. I still have the failed part in case you are interested.

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.

Since the first day I had the new car it has pulled to the left, it has been in the shop 4 times to be fixed, each time I get the car back with the same pulling problem, on the final time it was in they tried to fix it 3 times unsuccessfully, they finally called me and told me there was nothing else they could do. Lemon Mazda CX9 is a lemon.
