Well, for their part, Chrysler/ Dodge has always had great powertrain engineerso. They've had a few hiccups, but far fewer than Ford/GM/Chevy. I think the legendary 426 Race Hemi probably helped attract a following of good powertrain engineers.Why is it a great feature? A few miles per gallon seems like a poor trade off to me. If just a few of the things that can go wrong with VCM do so the owner will sure be sorry they have this device, I do believe!!! I am not trying to be argumentative, just concerned with the new Ridgeline not living up to anticipated positive results. I love my Ridgeline, and like so many other folks who own a Ridgeline and visit this forum, I had hoped for better!!
