This will be my 3rd time having this [XXX] Plastic oil filter/cooler housing replaced and this will be 2nd time having done less than a 2yr time-frame... But this time; after getting the oil changed at Walmart today, my car was about to catch on fire from majority of the oil was running done on the passenger side of the car where the transmission sits and burning off of the Hot [XXX] Catalytic Converter! It's [XXX] shame that Chrysler/Mopar had more than enough complaints about this well known Catastrophic Issue and won't take any Accountability for it... That's why Dorman [XXX] and a few more companies had at least stepped up to the plate and created an better version, of the oil filter cooler housing. Not only is it better but is also all aluminum and doesn't warp or become brittle under extreme conditions from atmospheric temperatures nor engine heat! [XXX] which eventually manifest as severe oil and coolant leaks. The number of complaints regarding the Pentastar V6 oil filter housing and cooler assembly is staggering. See them here, at [XXX] . There have been so many complaints – with the OE replacements even, that Chrysler has discontinued the manufacturing of the Pentastar oil filter housing and cooler assembly. Even more surprising is that Chrysler has known about this problem for a long time and has never issued a recall.

LOSS POWER ON THE HIGHWAY IN THE PASSING LANE SO I STOPPED AND CHECKED OIL LEVEL. THE OIL WAS LOW AND FOUND I HAD A MAJOR OIL LEAK FROM THE OIL HOUSING. TONS OF FORUMS ONLINE DISCUSSING THE PROBLEM. TOOK IT TO THE DEALERSHIP WHERE THEY HAVE 14 OIL HOUSING KITS THEY ARE WAITING FOR TO FIX CUSTOMERS VEHICLES. THIS IS COSTLY AND SHOULD BE A RECALL ITEM.
