We recently started smelling antifreeze when we got out of our 2014 Jeep Wrangler Rubicon. My husband was adamant that you shouldn't just be able to smell antifreeze so we went on a hunt to find out what was wrong. Mind you the Jeep only has just over 32,000 miles on it and just came out of warranty in September. I of course went to the computer to do some research. I found quite a few complaints of just this. Most people just gave up and couldn't actually find the leak. The few that did find it found that it was coming from a cracked thermostat housing. My husband then went on his hunt and sure enough there was antifreeze residue on the thermostat housing. He cleaned it up and we went for a drive. The Jeep is never getting hot and isn't losing enough antifreeze that you would notice. When we got back from our drive he let it cool off and went looking again. There was again antifreeze on the thermostat housing and now you could even see the liquid very slowly oozing out of it. So off to the dealer I went. Sure enough, just got the call and the thermostat housing is cracked and of course it isn't covered under warranty. I have contacted Mopar and we will see if it does any good, but I just wanted to give a heads up. This seems to be a very common problem in these Jeeps. Hopefully this will be enough to get others to catch it before their warranties expire since it's $324 to have it repaired. I am hoping that sometime in the future something is done about this since the only way this part could crack would be because it is faulty. We love our Jeep, it makes me sad that there is already something wrong with it!
