Steering Is Tight problems of the 2009 Dodge Grand Caravan

Vehicle while both driving on road and in park stalls. It givens no notice or warning that this is going to happen. At least 10 times I have noticed that the ignition switch has "moved" from the "run" position to "accessory," by itself. I have taken it to 3 different dealers but each has said they couldn't find an issue no codes have been coming up in the computer. I even had it stall in the dealer when I picked it up yet they have not done anything to fix the problem. When it stalls the steering wheel is extremely hard to move. I have 3 small children in the car when it stalls on main roads it is very frightening and dangerous trying to control the car, put it into neutral or park and get it to start or try to get to a safe place to restart it! I have contacted Chrysler-Dodge customer service, service managers etc all to no avail. I asked the dealer service managers if there was any recall and they told me there wasn't any. . . . I see on NHTSA website there is one but it is for 2010 and up but the 2009 vehicles also have the same stall problem! report receipt date: Mar 01, 2011 NHTSA campaign number: 11v139000 component(s): electrical system.
