Battery Cable problems of the 2010 Dodge Grand Caravan

My 2010 Dodge Grand Caravan began having issues about 6 months ago. The abs light would light up and beep on and off and was taken to the dealership and they stated they could not determine the problem without it occuring at that time. As months went on the problem became worse. All the dashboard lights began turning on and off headlights would dimmer, clock and radio would shut off. Took to a few mechanics and none could determine the problem. The problem got worse battery light began staying lit. We then replaced the battery and the battery cables. The problems persisted, we took to another mechanic who stated the alternator needed to be replaced. We replaced the alternator and the vehicle was fine for three weeks, then the problem started again all the lights lit up, the air went in and out, the radio shut off and out of nowhere the car shut off while about to turn at an intersection with my children in the van. We have taken the vehicle to many different mechanics even the dealership and none of them can determine what is causing this issue. Through the internet I see that we are not alone with this problem. I don't know what to do besides attempt to get rid of the vehicle. This is the vehicle I bought to transport my children; I've been paying for rental cars because I'm scared to drive it. With as many complaints as I've seen for this issue you would think there should be a recall. Someone is going to be seriously hurt or dead if they don't do something about this.

Van started and key stuck, then when the key get finally removed the engine stay on and won't shut off unless remove cables from battery. When the battery cables are connected again the engine start by itself without a key or the ignition is on without the key and the only way to shut off the van or to turn off the ignition is to disconnect the cables from the battery or it stays on or won't shut off. Running the battery out and your gas tank empty.
