2014 Wrangler, less than 60,000 miles, oil filter housing cracked. Leaks a ton of oil now, splashed in the exhaust, stinks, and could possible start a fire. For some reason this is a known issue for this particular year and model but there isn't a recall 🤔

The oil cooler assembly cracked causing oil to go all over the motor and transmission. It's around 800.00+ to replace this plastic part and it's a very very common problem in the 2014 Jeep Wrangler. Why hasn't there been a recall? I literally started it and let it idle for 10 minutes before leaving for work and it done this in my carport. Oil was everywhere.

Jeep has a known epic failure is design flaw in its 2014 Wrangler when it switched from a metal oil filter cooler housing to a plastic oil filter cooler housing. Hundreds of cases of the part breaking/leaking oil all over lower engine and exhaust which is a fire hazard. My part leaked oil over an unknown amount of time because I live with a gravel driveway.....now dealer shows me "metal" like glow to oil which could be engine failure.....hundreds of cases

Mopar oil cooler housing, which houses a cooler and oil filter, sits on the engine and has cracked, causing oil to leak out of it. Oil leaks down the engine and onto the transmission housing. This is a fire hazard and a common issue with 2014's, which can be found via a quick and simple google search. Car was stationary when I discovered the leak. Car dealership verified the issue and supplied me with an estimate, stating this is a well known issue. About 3 hour repair and could cost 700-1100.

I have taken my Wrangler in for the 2nd time now with a black sludge in the overflow and radiator. The last dealership replaced the radiator, trans cooler, all hoses and and flushed. Now one year later I am having the same issue and the vehicle only has 50,000 miles. The dealership is now telling me they have no idea what the issue is, and is wanting to charge me for a flush. This coolant is rated to 150,000 miles I should not need a flush. I believe I may be apart of an ongoing issue with sand in the heater core as they want to replace this but saying it may not be covered under my warranty. There is always an odor of anti-freeze with this vehicle. I have noticed when around other Wrangler jk's I smell the antifreeze with them too.

First few years had 2 major oil leaks where they took apart car to repair. I brought car in for oil change asking them to check oil that is leaking from bottom. Was told nothing was leaking. Weeks later my engine went out while driving 2 cylinders $4000 repair. Two months out of warranty. Now my Jeep is leaking oil again and I'm sure if I trust the Jeep dealer at this point. Please help
