Anti Freeze Slowly Disappearing.

I have a 2017 Jeep with the 2.4 in it with about 18,000 miles. I have noticed the antifreeze is ever so slowly going down. I will need to add soon as the plastic fill container is now almost empty. This has been happening sense it was bought. As I said a very slow leak or evaporation. I didnít pay much attention to it at first because it will vary some with temperature but now I am certain. I looked very closely for any external leaks and canít find one. Now I fear it is internal. Question I have is, is this normal for the level to change over a long period of time? Other vehicles I have had, I never had to add. Does anyone else have this problem?

Thanks

I have not had this problem In my 2018 Latitude. If it is internal i would check the oil and see if its milky looking just to see.

I have just over 12,000 miles on my 2017 2.4. Had to buy antifreeze and add some as it was slowly getting lower. I have checked the oil dipstick and see NO milky substance...also no leaks on the cement, on the engine or anywhere...I will just keep checking as I do the oil ever so often.

You both have leaks. Check the hose connections for weeping. Especially on the header tank.

My wife's 2005 Jeep Liberty does that from time to time, always has. Granted, it now has over 260,000 miles on the original engine but it does not burn one drop of oil and has never left her stranded. I went through the "why ?" phase with hers, could never find out why except for one time I didn't have the cap on the bottle fully tight.

There is no rhyme or reason why it drops, it can go 10 months or more at full, the one day it'll be half empty. She travels the same route to work every day, no heavy traffic as she leaves at 0-dark-30 each morning. No staining in our driveway, no coolant smell when you pop the hood, it's just GONE. I replaced the cap on the bottle with a new OEM, made no difference. It never overheats, gauge never gets above normal, the bottle is just low.

Since that is the only "issue" whatsoever with that vehicle, and I mean the ONLY ISSUE, I just keep tabs on it. More so now that I own a Renegade; I have to check my oil weekly due to the "David Copperfield Effect" of oil in these infamous engines, so I incorporated checking her coolant at the same time.

A little advice though. In your Renegade, DO NOT pour in regular off-the-shelf green antifreeze. It's not the same as what's in your cooling system. Sure, the bottle will say "compatible with all types of antifreeze", but DON'T. Mixing types of antifreeze can actually gel in your system, something you don't want. For a little top-off, use distilled water, never regular tap water. Bite the bullet and pay the insanely high price for a gallon jug of the right stuff from the dealer. It'll hurt your butt a tad for a bit, but it's cheaper than replacing the engine or cooling system because you wanted to save a couple bucks on a gallon of coolant.

Others may chime in saying "you don't have to use...", "you can use this instead" "don't pay dealer prices" "you're foolish to believe that 'special coolant' line", etc. or any of the numerous paranoid conspiracy theories people have about using factory/dealer parts, but I don't pay them any attention. I'm way too old to play the "they said use this, but I used that, and I saved XX dollars !! Neener-neener !" game. I use what the factory says thereby you can't go wrong. If something does happen, they have no argument. You used THEIR product, your purchase is in their computer. That alone is worth the couple extra bucks.

It should be covered under warranty take it back to the dealer. Have them note it, even if they cant find a leak.

Slow coolant loss covered under warranty??!! The warranty doesn't cover engine oil feed-and-bleed rates of loss. Do you think a little bit of coolant weeping out somewhere will be covered? I doubt it.
I'm with Mud Pie. Monitor it. Add distilled water. If you add more than about a half-gallon of water start mixing in the correct coolant.

Thanks to all of you for the quick reply's.

Just to add a few more things. The oil is perfectly clean or it at least looks like it on the dip stick. I have had no real issues with this Jeep Renegade other than it burned a lot of oil when new. The oil burning issue has slowed to the point where it will just be on the add (dip stick) mark when it is time to change it, which will be about 1 quart in 7500 miles. It's a bit disappointing but acceptable now. Other then that i have been petty happy so far. I like the idea of taking it to the dealer and making sure they note the loss of anti freeze while it is still under warranty. Does anyone know it the factory warranty for the power train is 3 year 36,000 or 5 year 50,000.

Thanks
