general problems of the 2002 Dodge Caravan

The steering wheel gets lock were ever I stop ,internal control failure, radiator heat constantly when I am driving ,.

I heard a "banging" noise while driving on the highway at 50 mph. So I called my dealer to schedule an appt for multiple of reasons and they found the following issues again with my car; my front brakes (shoe pades, rotor's turned) needed to be replaced again since I've had this car and the car only has 45,000 miles on it and previous to that, the dealer replaced the shoe pades again at 19,000 miles?? also at 19,000 miles, the dealer had to replace the "bushings and links" for the front end and again at 45,000 miles two days ago. I am strating to wonder if there is a direct link between the two parts going prematurely. I also had to replace all four tires because due to the wear/tear on them becasue they were unsafe. The dealer won't warrenty them, so I had to buy new set of tires at 19,000 miles. I think the tires worn out prematurely due to all the front end problems that I am having. There also have been a number of "power steering" issues with my vehichle since I purchased it. I believe there has been two recalls on the power steering unit and had the dealer take care of them. (had the car towed because the power steering won't work and it leaked all over my new driveway) I 've had the car back to the dealer 3 times for "power steering" leaking. The latest new was the a "boot" of some sort in the "rack-and-pinion steering" was the cause of the power steering leak and they also found an oil leak on the headcask cover too. After everything was finally finihsed (after 2 days) I picked up the car and drove it home but I am going to bring it back to the dealship because now the car is swaying left/right and the dealership said they did a front end alignement because of all the work they had to due to the vehicle.
