I bought my 2016 Willy's 2 door in October last year and it just clocked over 18,000 miles recently. Lately I have noticed that when i drive next to a wall or another car I can hear an offbeat ticking noise that sounds different than the injector noise, when I listen to it idle through the wheel wells I don't really hear anything that sounds off to me and when I open the hood all you hear is the injectors and everything sounds normal. I have tried listening to other wranglers start up when they are parked near mine at the store or something but I cannot tell. I mostly hear the ticking when the motor has been running for a while and the cooling fan has cycled quite a few times already. Before I take it in to the dealer and start to deal with all of that fun I was just seeing what anyone else might know about this.

Hey Greyghost51,

I didn't see any TSBs on file that matched what you're experiencing, but please let us know if we can help make an appointment if you decide to use your dealership for service!

I had the same thing happen to me on my 2013 rubicon. It was something in the clutch that was loose. Brought it to the dealer bc I had just got it replaced by them and they tightened something inside.

I appreciate you taking the time, mine is just a weird noise I hear, I dont remember hearing it when I first bought it but I was also so overwhelmed that I actually bought the Jeep that I wasnt thinking about noises. Everything runs perfect and it drives smooth and there is no rough idle at all. I just heart this noise and I had a 4.0L in my old Cherokee that made tons of noise but everyone says these 3.6 engines are supposed to be whisper quiet and that has not been my experience.

Yea defonately not. Haha. Mine ticks all the time. But that's just the normal ticking. Been making the noise since I drove it off the lot with 0 miles on it.

Every ticking noise I've heard my engine make does not sound weird or abnormal at all to me, but I watch these videos people post and mine sounds similar to theirs and they had to get heads replaced and lifters went out and exhaust valves collapsed. With how much these brand new Jeeps cost it just concerns me.

Now you made me worry. Lol. I'm not far from my 60000 mile warrantee. Maybe I should have it checked. Even though they will say it's bc my lift and all the mods.

Here is the video I watched where mine sounds similair

I guess I should just make an appointment just to be safe, from what I have been reading supposedly the ticking was mostly on 2012, 2013, and 2014. Apparently Chrysler released a new head designer that fixed the ticking for 2015, 2016, and 2017. But then I also read that they ran out of the new head designer and just continued to use the older design. There is just too much out there to read.

I just had my 15 JKU to the dealership for lifter ticking. It started doing it recently and only does it in the morning when I first start it up. Funny thing was as I was sitting outside waiting on for them to change the oil. They were jockeying new trucks around on the lot and there was was one that had lifter rattle BAD.. They didn't seem to care about either.. Feel sorry for that buyer.

I'd have it checked. I would also take a look to see what head the engine has on the left bank of the engine. I honestly believe some people with late model JK and JKU's might have an AA or an AB head, even though there were revisions. Chrysler didn't scrap those heads, and might have used them in later JK and JKU's hoping they wouldn't fail, they weren't all bad, and they spread out warranty claims. It wouldn't be the first time it was done in the auto industry, and certainly not the last. I was told by a few different sources that this was the case, but I haven't seen or heard a later model JK or JKU with the problem as of yet.

Where at on the head would I find that number?

There was thread here a few years back that ran on and on. It showed pictures and how to determine what head you have. I had it saved and can't seem to find it, sorry. Maybe someone else can find the thread and link to it here.

The code is just about dead center along side the head, near the 02 sensor which is almost vertical. You'll need a mechanic's mirror to read it, the thread has info on how to decode the numbers. HTH

I'll keep digging to see if I can find someone else's pictures. Do you know if the AC heads have had any issues like the other 2?

As far as I know no, but no one has posted what heads they had on the later model years with problems. But I might have missed a few threads. What I've seen is people with the later models either had problems with lifters, rockers, or both, the head itself was OK. But I haven't read all of the threads with ticking complaints. Now if you have a bad head, and it is an AA or AB head, then what I thought and was told about some of them in use in later model years would be correct.

Are you certain it isn't injector noise? Some of these engines tick for a second or two after sitting overnight. If that's the case I would consider a good synthetic 5w30 oil.

I mean when I drive it I hear the normal ticking of the engine and when I open the hood everything sounds normal, really the only thing making me question a ticking is after I have been driving it a while and the cooling fan has circulated several times. I hear a sort of intermittent ticking when I drive next to a wall. I cannot hear it when it is in park and I just put my ear down to the wheel well or anything. Really everything sounds completely normal to me but I hear people say how quiet these motors should be and mine has just not been quiet at all, but to me it all just sounds like normal operating noise. I just want to know if I am imagining the tick to be something worse than it is or if I really do have a problem starting to form in my brand new engine. Ive always used penzoil platinum full synthetic 5w20 and a mopar filter at every oil change which I do every 5,000 miles religiously.

After reading your latest reply I have a feeling you are spooked by reading up on things like this. It happens, trust me.

No CEL, it runs good, drive it, and don't worry. Odds are there is nothing wrong. I'd consider Pennzoil Platnium 5W30 next oil change, you might be pleasantly surprised, and hear little to no noise at all. ;) Stick with the Mopar filter, or a Fram Ultra filter. I think you'll be good to go and notice an improvement. I run the Pennzoil Ultra 5W30, and so far it runs like a champ.
