If you own a 2011 through 2013 Chrysler product with the Pentastar V6 you will likely experience a broken retainer for the oil filter bypass valve when the oil filter is being changed. The valve is plastic and is under pressure with a stiff spring behind it. The plastic fatigues and breaks away and the valve and the spring typically go flying when the filter is pulled out. Chrysler requires that a entire new filter/oil cooler assembly be purchased for several hundred dollars and a couple of hours labor. Dorman products now make a repair kit, p/n 917-992 that for under $ 30. provides a two minute permanent fix. My local quickie oil change facility didn't know about this rather common failure which is rather surprising since I would have to believe that all the Pentastar engines in this model year range will experience this failure eventually. I would recommend that everyone that has a 2011 through 2013 buy one of these kits and keep it in the glove compartment. Don't count on your mechanic, quickie lube joint or certainly the dealer, to be aware of this recently introduced Dorman repair kit. Thanks Motor City Mechanic !
