Steering Is Tight problems of the 2008 Chrysler Pt Cruiser

I have been driving this car for a while and on the day this happened I had returned from work parked in my driveway with no problems. When it was time to go back to work I backed out of the driveway and noticed the car handled hard. I stopped shifted it back into park and then went back into drive still the steering was hard to turn. Of course the was late Friday memorial day weekend so I ended up renting a car for 5 days because of the holiday and the fact I had an extended warranty so no Chrysler certified mechanic was on duty to work on my car. Tuesday morning I go over to the dealership only to be told a belt had slipped and there was no explanation for why it happened. I wasn't charged for this but it cost me a tow and 5 days of rental for a car so I could get to and from work. When I got on this site I couldn't find any info so I still am not sure if the car is safe to take very far.
