Squeaking disc brakes are sort of a fact of life. A lot of them do this. While it can be annoying, it doesn't affect how the brakes work. Your Chrysler repair guys will probably tell you this unless: 1. There is some sort of technical service bulletin on this due to customer complaints, etc. or 2. They can somehow get away with repairing it and charging the repair back to Chrysler. More than likely, you'll get the "it's normal" explanation. Try anyway as the car is still under warranty.
Now "grinding" brake noises are something else. Our '96 Town and Country goes through front brake pads about every 35,000 miles (56,300 kilometers). If your car has been used in an area with more slope than normal, it may be due at 44,000KM. Squeaking can be annoying, but grinding is definitely bad.
Best,
