Power Window problems of the 2006 Chrysler 300C

The car has been stalling out after being started. Now it is almost shutting off or becoming unresponsive mid acceleration from a stop sign. The car will at random stall. The engine does not need to be restarted so far while driving. It will "die" for a few seconds and then comes back again just short of complete engine shut down. Rear window on passenger side is also non responsive. It has only worked once since I have had the car.

I have an 2006 Chrysler 300c, 3 power window regulators went out at the same time. Took it to the dealer and it now is going to cost over $700 to repair. I asked the service tech how can 3 regulators go out at the same time and I was told because of poor quality parts that he has had to replace a few of them. My question is he knows that then so should Chrysler. If one unit went out then I wouldn't be complaining but three at the same time something is not right. Thank you for your time lawrence.
