Air Conditioner problems of the 2001 Mazda Tribute

I were driving down a hill when my car engine dies while driving on the highway, the (radio dies, a. C. , engine, and steering wheel tighens. This is the second Mazda Tribute I owned in a year with the same problem that the company can't fix. The other s are not as major. I feel this is a( lemon and a recall) if the company can't the problem. Safety play a big part in this case when the engine dies for no reason. This is a highway safety issue.
