2013-2014 Acura RDX VCM, Vibration Problems
I purchased the car in June 2013 and drove it for 2000 miles without a problem. Then around the 2000 mile mark I noticed a rumble and vibration from the undercarriage and engine compartment. I called the dealer and they said they were unaware of a problem. I notified the Acura corporate office and they said they are aware of an issue and the engineers are working on it but that I should take it to the dealer for diagnosis. When I take it in a mechanic and I go for a drive and the mechanic states that "I feel it a little" and "ok there it is again but not too bad". I am in the passenger side and my butt is shaking like crazy and I hear the engine making a grinding noise. I have to take it in next week for a full diagnosis where they drive it feel for issue then unplug vcm and drive it again. The issue is the VCM. You can feel the engine switching from from more cylinders to less cylinders. Based on my reading of issues with the Honda v6's it appears that I am in for some problems (like oil consumption as I get more miles). Why would Acura adapt a 6 cyl from an 2008 accord that is the subject of a settlement of a class action lawsuit and has so many issues with more miles. I wish I read this information prior to my purchase. If you have this issue do not let them tell you this is the way the car drives. It did not drive this way when I test drove it and for the first 2000 miles. Other people in other forums stated that driveshafts were changed, motor mounts replaced, tires balanced and aligned and the problem comes back.
