Engine Rattling And Whining Sounds problems of the 2012 Chrysler 300

I had just left my house and was approximately a quarter mile from home when my son and I noticed a strong smell of something burning. Then the radio turned off. I looked down and the message center said "battery saving mode". I had just put a new battery on less than 4 months ago. Then I heard a whirring noise under the hood and the vehicle would not accelerate up a hill. The red outline of a battery appeared on the dash. I took the car back home and parked it -- then had to have a new alternator installed the next day. Mechanic said there was definite evidence of the alternator burning up. After picking up the vehicle with the new alternator -- my heat would not blow out the front vents. Turns out the actuator had gone out. I am still trying to determine if this was caused by the electrical system or just a really strange coincidence. I am still afraid to drive the car when I get on the interstate even with the new alternator because I was told it could happen again at anytime without knowing the cause of the problem.

On August 14th 2014 I was driving my Chrysler 300s through town at 31mph when my traction and antilock brake lights came on my dashboard. My "battery save mode" info also illuminated on the dashboard. I then heard a whining sound coming from outside the car from under the hood. We immediately pull over into a gas station and opened the hood and the alternator was on fire melting and burning. We immediately shut the car off and the car is completely broke down. Nothing works on the car now. We had the car towed home. I have 42300 miles on the car only 6000 out of warranty and this car is catching fire. If I would not have pulled over right away I hate to think about how my children and I could have been seriously injured or even death.
