Air Conditioner problems of the 2012 Dodge Journey

Over heating and running hotter than usual. Unusual smell from engine when accelerating quickly. Popping when making sharp turns. Air conditioner turning on and off or up and down randonly.

Crankshaft sensor and 2 camshaft sensors had to be replaced. Going uphill on a bridge that I travel 2x a day for 365/year, it decided to cut off while going up the bridge, I went from 52 mph to 0 mph and coasted to the foot of the bridge, it would sputter when trying to turn on and then after 20 - 30 mins, it turned on as if nothing happened and I drove home. The next day tried to drive over the bridge and it did the same thing going up hill. It just stopped. Mechanic says I had 2 bad camshaft sensors and 1 bad crankshaft sensor. The car still hiccups and shutters and acts like it is going to cut off again as I go uphill with the air conditioner on. I really believe in my heart the air conditioning is draining the power and somehow causing adverse affects elsewhere, I just dont know how I can prove the correlation. I don't feel like replacing those sensors is the end all to the story. I just don't know what else to do.

The instrument panel which controls your ability to turn on radio, tape player, and heating/air conditioning has gone out. I purchased this car in November 2013, and it's unfortunate for me that I did. Another failure of this automobile is when it rains heavily, my back doors fill with rain water. You can hear it inside of the doors. It makes me believe that the car was in some type of flooding condition. My back wheel on the drive's side also has a brownish-red tinge that appears to be rust. I am disappointed. Did I see the correct report of the reliability of the car? when you place the key in the ignition and start, or use any of the modes on the ignition, the screen was constantly stating, "loading," and it turned black and is out. This happened before in 2014 and I thought that maybe it was just a glitch, but it isn't.
