thank you for the help.

I pulled serpentine belt off, started engine ran it briefly and the noise is still heard without any serpentine components engaged. I assume that points to flex plate as you have previously indicated? I am getting beyond my level of comfort in the repairs so I am taking it to my mechanic on Monday.

Replaced idle pulley, replaced tensioner assembly, replaced serpentine belt. Noise still exists, most noticeable when turning on AC. AC blows cold, so maybe AC clutch?

Thanks guys, pulling it apart on Tuesday and will report back

This is also heard when AC is not on. Heard alone; with low throttle engagement, or when turning steering wheel with no throttle, or when turning on A/C with no throttle.

2012 Dodge Journey 3.6L SXT Anyone diagnose this noise? It is heard at low end throttle with rpm between 800-1200, also repeatable when engaging power steering(turning steering wheel), as well as when the A/C is turned on(this is what is heard in the video). https://streamable.com/j3ygdv

So took it into to one of my local dealers, quoted this TSB and asked them to check the diagnostics. They kept it for 2 days, called me and said "we know it is misfiring, but until we get a check engine light/code thrown at us, we aren't going to throw parts at it..." So any advice what my next plan of action should be? p.s. Had a friend replace the spark plugs, but not ignition coils. Could it be coil issue?

What is the estimated costs of having this done? My 2012 Journey V6 is doing this exact shutter after coming to a stop and transferring from brake to accelerate.
