• “In the 9 years I have owned my Jeep I have now replaced the oil filter housing twice. Each time has caused me over $300 just for the part, which is PLASTIC from the dealership to my mechanic then over $1000 to install. My mechanic explained to me that when plastic is heated then cold with oil it will eventually crack. This then drips on the exhaust which causes either smoke through the vents or a small fire eventually. This needs a recall.”
