When I accelerate hard, maybe 75% throttle, at any speed, I'll notice a distant burning smell. Has anyone experienced this and found the issue if it is an issue? 2016 3.2L TH

Never had this problem with any vehicle.
Close all of the vents and/or use recirculate mode to see if the smell is coming through the vents.
Possibly a dirty cabin filter?
Check fluid levels and try to determine if something is burning.
If the oil filter housing is cracked and leaking oil it may be getting onto an exhaust manifold or catalytic converter.
The transmission cooler line fittings forward of the radiator have leaked on some Cherokees.
If a brake pad is dragging it could overheat.
Try to identify what kind of fluid is causing the smell.
Engine coolant and engine oil will have different odors.

Definitely not cab filter as I've replaced that. I don't believe it's burnt coolant, doesn't smell like it. Engine oil doesn't go down at all so I wouldn't suspect engine oil. I'll crawl under and try to see if anything is leaking

Could it be a dead animal being cooked in the engine compartment?

I have noticed an exhaust smell after doing a full throttle acceleration onto the highway. Goes away at cruising speed. Don't notice it any other time. Checked for exhaust leaks, none found.

Yeah the smell goes away right after I slow the engine down a bit

Tire Smoke.....LOL....

My 200 did this too. I haven’t noticed it in my trailhawk, but I chalked it up to being a feature of the pentastar.

This was common on my 2.4 Sport whenever I hit the throttle hard for passing etc: I always thought it smelled of burnt transmission fluid. Went away after a few minutes. Never had it checked out as I traded it for my Trail Hawk but I have experienced it.

One thing you never mentioned is what it smelled like. Oil, Transmission fluid, plastic, rubber etc: Might help with a diagnosis.

I'm not 100% sure cause the smell is kind of distant and goes away so quickly. I wanna say it doesn't smell like any type of fluid. If it was coolant or ATF I'd know right away.

I took it into some mud today for a while and stepped on it a few times and didn't seem to smell anything this time around.

Hah, I wish. The AWD works to good!

Make sure this is not your burning smell:

This is a new problem I will have to check on my 2014.

I also notice this in my '16 Trailhawk, however, I just attributed it to the custom intake & exhaust on her.

My Cherokee does the same thing smells like something is burning on the highway

took it in they found nothing

currently at another dealer however before i took it in i did find oil on my air filer and also oil on the top of the engine

Yeah my engine bay is totally spotless. I really don't think it's any burning fluid otherwise I'd know. Please let me know what they find!

If you are hitting the throttle hard, you may be going into Power Enrichment mode. Not quite as bad as open loop, but the priority is on (you guessed it) power; dumping a lot fuel instead of fuel economy and emissions. You could be smelling unburnt fuel in the exhaust.

 

[007]

Yes! My 2014 V6 does the same thing, exactly as you describe. I think @Rojhan's comment makes the most sense. It's never caused a problem with mine, either, as far as fluid consumption, oil in engine bay/air filter, etc.

I spend a fair amount of time on rocky desert trails here in Utah.Slow going and 4lo at times
And I notice a “hot” smell but have never had an adverse effect from it.

 

[Rand]

my 2017 does this
at first I thought it was spilled oil since the dealer grease monkey was slinging it around on my free oil change the day before.

Does it anytime you floor it on an on-ramp etc.. sometimes you wont smell it but if it wafts into the car it is Very stinky.

I would say it's more of a hot smell. Not really a specific fluid being vaporized or anything like that.
