How are the CVTs in the 2011? Reliable?
Some CVT's have lasted over 200k, but they do need to have the fluid and both filters changed every 30-50k miles (instead of 120k like the manual says) or premature wear and early failure can result due to scoring of the valves and bores causing pressure issues.

If there's no service records, you might talk to a transmission shop that knows CVT's and see if they can road test it while checking the pressures.

Here's an example:
 
The earlier 2.4l were also solid cam followers and will tick some, especially in the winter until thoroughly warmed up.
 
Solid and hydraulic are two types of valve actuation. Solid has the valve lash or clearance preset to a gap, say .010 inches. Because of this, solid lifter/follower valvetrains tend to make ticking noises. Hydraulic systems use oil pressure to automatically adjust that gap to zero inches. Giving near silent operation.
 
I replaced my hearing aids with much better quality ones last fall, shortly before buying my 2010 Patriot. As received, they have a bit too much boost in the high frequencies, which I can get adjusted, but haven’t bothered to yet. I use the manufacturer’s app to fine tune it to my needs for now. I figured that out awhile after I got the Jeep. I had read somewhere in the forums about the valve lash sound, and was amused to find that I could hear the valve lash for the first mile or two of driving in the winter, and then it would suddenly fade out. With the hearing aids more properly tuned, I don’t notice it now. Nice to know I have a diagnostic tool, though.

Kinda takes me back to my first car, a 1964 Rambler American convertible with a straight six with adjustable lifters..
 
My 2015 has the 4th CVT. I'd leave it alone wouldn't touch it. If you don't know last oil change then maybe that should be done but warning, it could make it worse. My original CVT was changed at the 60k recommended warranty service time. Don't know what was wrong with it but dealer called and said could install a new one for under warrantee for $100. 2nd one would occasionally over-heat into limp mode and was changed under warranty again. After many miles of hard driving #3 became scatophiliac and failed on the freeway. I changed the oil & filter at home hoping to cure the problem. No effect. Dash lights were flashing, gear selector indicator couldn't decide what gear to stay in, if you tried to drive it the temp light went on & off and it tried to change gears every 5 seconds. I bought #4 on eBay for $1800 w 40k and paid a shop $1000. to install and program. No change. It drove about 3 miles and started doing the exact same as #3. Shop got it back and a week later told me it needed a Transmission Control Module (TCM). Took 3 weeks to get from Chrysler for another $600 plus install and programming. ASE Shop wouldn't warranty the work if not new TCM from Chrysler. Trans fixed and driving today. There is some very light buzzing noise that I believe is normal Planetary Gear wear, the same as my wife's New Bettle, but I'm not touching it and it has not changed. And . . . since the problem turned out to be TCM . . . I have #3 sitting in garage that may not have anything wrong with it! :) About the previous comment here about finding parts or other mechanics working on them. Good luck. There ain't that I know of. The one shop I found that told me they tried to work on them told me they discovered that they couldn't get parts. These CVT's are from a 3rd party independent manufacture and no one that I have been able to find is working on them, not even the dealer . . . they just swap them out. (They've told me that.) Good luck. I'm treating #4 kindly.
 
I guess others have pretty well explained the ticking noise. Mechanical lifters as described above will make a clicking sound.

As for the CVT, the weak point was the inadequate maintenance schedule in the owners manual. As Sandstone said, it needs to have its fluid and both (2) filters changed at least twice as often as the manual recommends. If the CVT gets the needed maintenance it's as good as any transmission. My first CVT failed at 110,000 so it never even made it to the first service interval. My replacement made it to 270,000 but it got the necessary maintenance. Unlike many owners I liked the way the CVT performed.

I've had several conventional trannies fail at <100,000 miles, and at least one almost made it to 250,000 miles. If it's made by humans, sooner or later it will wear out.

Indeed, Jeep dealers will not service the CVT, only replace it. Since Nissan used the same Jatco tranny, you may find a Nissan dealer who will do repairs. However, the CVT is relatively simple. Aside from a few minor items there isn't much to fix, hence the replacement policy.

PS, @Roadwarrior, you made me look up a new word. :poop:
 
I bought my 2012 new and it has been the most trouble free vehicle I've owned. I have over 130,000 on it now. At around 100,000 it started a whine in the cvt. I took it to the dealer for fluid and filter change, and no more whine. It has worked great and I like the way it works. The tick is common with the 2.4 and is likely not something to worry about. I've had a few, and they all have done it.
 
My 2011 2.4 has over 340,000 slight tick, change oil full synth every 5000 Use Lucas fuel treatment religiously Would not be afraid to hop in today and travel from east to the west coast with it
Which transmission?
 
Does the CVT have 6 speeds?
My window sticker from new says 2.4 FWD CVT but it can be manually shifted 1-6
Short answer, yes. Long answer, the cvt should just smoothly adjust the ratio at a steady rpm (say 3000) and the speed would just steadily increase. This lets the engine operate at its most efficient rpm for power and economy while letting the transmission vary the speed. But folks aren't used to that as car drivers and equate that sensation to a slipping transmission so modern cvt vehicles "step" the ratios to simulate a standard automatic shifting. When Subaru introduced the Justy back in the 90's, a lot of folks complained the transmission was slipping due to them just letting the cvt be a cvt.
