Ball Joint problems of the 2014 Toyota Camry

I called Toyota (customer experience center) to get more detailed recall information related to my make/model vehicle. The recent recall is for the 2014 Toyota Camry- steering control loss; front lower suspension arm/ball joint. I am a consumer and it is my right to get detailed information on this issue related to my make/model vehicle. The representative from Toyota refused to provide me with any information.

I filed several complaints about the tires bouncing and excessive vibration coming from the front end of the vehicle. I was told by the dealer that it was a tire problem, and that I should try 40 lbs. Of air instead of the recommended 35 lbs. I contacted a local bridgestone dealer and was told not to exceed the recommended pressure. The Toyota dealer acknowledged there were a lot of similar complaints and that it was the fault of the tires,. I have 12,000 miles on the car and the front tires are worn out and Toyota is refusing to DE anything. I believe the problem is caused by the ball joints or front end suspension, but can't get anywhere with Toyota. If it's an ongoing tire problem as the dealer says why hasn't it been addressed. If it is a manufacturing defect why hasn't it been addressed. At 50 miles an hour the tires start to bounce and shimmy and the vibration can be felt in the steering wheel. The car feels unsafe at highway speeds.
