Power Steering Pump problems of the 2010 Chrysler Town & Country

I took my van in for a simple valve change because it was using a lot of oil on 2/15/16. A week and a half later I received my van back and it stalled in front of a tractor trailer truck. Van was returned to the dealership and they claimed to repair /install new gas pump, egr valve, gaskets, crank sensors etc. I received my van back on 4/2 claiming everything was repaired. The van was no longer stalling. On 4/3 while driving on the parkway, in heavy traffic my brakes, steering wheel locked and van shut off while driving. Just missed going over the guard rail. Again took th van back to the dealership, contacted Chrysler customer service which made the dealership owner very irate. My van was in the dealership from 2/15 to June. I got the run around about we are doing everything to repair your vehicle. Guess what, it is still not repaired the van continuously stall anytime you made a hard turn. It was at the point of no return. The longer the dealership had it the worse the van got. Meanwhile all of this extra stress is starting to affect my health. I paid for a $42,000 van and even Chrysler has no idea of how to fix it. I got fed up in June and asked to have the van returned back to me. After more than 3 months they were ever so happy to return the vehicle back to me. As of now I still don't have all the receipts of exactly what was done to the van. All I know is that I would never buy another Chrysler again because of the treatment received and their uncaring attitude about the safety of the vehicle. At this point I found out that I am not the only one with this stalling issue. I feel Chrysler is aware of it and don't know how to go about correcting it. The vehicle was in the dealership at the time on 2/15 for a recall for the ignition node(r03). I don't know if the recall initiated all the action or incompetence. I have towing receipts in excess of 100 miles.
