One problem related to engine noise has been reported for the 2005 Chrysler 300C. The most recently reported issues are listed below.
Whenever I fill up at the gas station about 2-3 minutes later while I'm driving the entire dash board will light up and the car will cut completely off. I have to put in in park and try to restart it about 5 times, each time the oil light comes on and it just stalls, once it does catch the speed fluctuates up and down but about 5 minutes later it happens all over again. I know it has nothing to do with the oil because I had gotten an oil change before I put the gas in the car. This had happened a couple of years ago so I had just stopped filling the car up and this time I forgot. The car cuts off while in motion, you can't turn the steering wheel, it just stops where ever you are, all I could do was cut on the hazards and keep trying to restart it, it sounds like you are trying to restart while it's already on, it makes a screeching sound, and sounds like it's trying to catch.
