All HEMI’s, including the 6.2’s. One guy on YouTube had a 300 with 400 miles and another one had a Durango with 64,000 miles.

You think the MDS causes this? I have a 12’ and I turn my MDS off every time, mainly cause I have magnaflow mufflers and it sounds like crap when the MDS kicks in, plus it doesn’t help with my gas mileage at all.

Yup. So much so that guys are deleting the MDS.

It is a 2016 Longhorn Laramie and I have never seen anything flash on the screen indicating MDS is active or feel a power change when scooting along.
I also have a 2006 Hemi with 173k (ranch truck) and when I recently changed the oil in it I heard the infamous tick when I first lit it off after the change. I didn't hear it afterwards so maybe it was the oil resupplying itself through the passages since pulling the filter allowed most of it to drain out.

5.7 Hemi problems
From the web:
How does the Dodge MDS work?
First, it reduces the engine's pumping work by closing the intake valve later. ... Dodge's fuel-saving MDS system seamlessly alternates between smooth, high-fuel-economy four-cylinder mode when less power is needed, and V-8 mode when more power from the new 5.7-liter HEMI engine is in demand.
Kinda like the old Northstar systems in late model Cadillacs.

Not exactly. When someone rebuilds an engine, they usually fix or upgrade what’s wrong. The shade tree mech usually don’t go that deep in it.
According to them:
“Remanufacturing products are not “rebuilt” to fix only what’s necessary to make them work again. Remanufactured ensures that every part is machined, every process completed, every time. Our remanufactured products are not refurbished or used. The products are stripped down to their individual components, cleaned, machined, and rebuilt to be at or better than OE specifications.”
