I once drove a 2014 Jeep Grand Cherokee Summit with the Hemi, and "Eco" would light up green in the IP when there was cylinder deactivation. On a car as expensive as the MDX, we really should have an indicator of deactivation, imo.There was a mod on the Jeep side for the same thing on the HEMI V8..
They didn´t have a light or anything so they retrofitted one so a dashboard light illuminate when it was running on V4 or V6. Perhaps there is a way to do the same here?
I have never felt anything. I just assume that when the mpg is close to 30 that the cylinders are deactivated.there's no light you can feel try to feel. cruise on hwy for a while then when you the gas slightly you can feel the other two cylinder come on or maybe that's just a placebo effect.
