In 2007 i was driving when i started hearing a knocking sound in my tires. i was had the vehicle checked immediately, but no determination was found. over the year i was forced to replace my tires 3 times because they would wear and i would slide and the tires would skid in simple weather. in march of 2008 i had to repair more tires and my ball joints on both sides in the front with wheel alignments. also in 2007 i started hearing a squealing sound in the engine, i had it checked immediately and was told my power steering pump would need replacing. but decreased once the mechanic put in power steering fluid. since then even now i still hear the squeaking and every month i have to put in steering fluid. i called chrysler regarding recalls relating to these problems and was told no recalls were in effect. i have not received any info in 2008 regarding these recalls that i now see online. also my automatic stick shift sticks especially when it's cold outside. i have almost hit something head on twice since december 2008 because it is hard to shift in park or neutral. *tr
