2013 RDX AWD Engine Issue

I've had my car since August. Drove awesome until November. Starting noticing a hesitation/vibration with the engine when trying to drive an maintain a speed. For example if i'm driving 30 mph and just try to keep at 30 by applying slight constant pressure on the gas pedal the engine will start to shake. Reminded me of when i needed a fuel pump on a previous car. Had the fuel pump tested and its fine. Since the issue i've also noticed my MPG has decreased. We would typically get 26-28 MPG on the highway now we're averaging 21-22 MPG highway. I've had in the dealership 3x and they say the vibration/hesitation is normal and how RDX drives. I've driver others when car is serviced and its fine. The Head Machanic said he can definetly tell their is an issue but they have no answer and Acura Corporate Engineers say thats just how they drive. I need help and suggestions?

A couple of suggestions....I'm not a mechanic but just offering hope.
1. I wonder what speed/load the VCM engages. Could be a bad sensor that engages the VCM?
2. Tranny. Again, a sensor might be interacting with the computer giving false load readings thus throwing the VCM into confusion.

Sounds like it could be related to the Variable Cylinder Management system as well.

Ours is also a 2013 AWD RDX. Our experience appears identical. The vibration is very, very noticeable at constant speeds of approx. 40 and 50 mph especially, other speeds at times too. Our experience with the dealer also seems identical. Our dealers assistance has also been the same. The Service Manager said news to her, no reported problems whereas the Service Advisor, post check-out a couple weeks ago (approx. 17,000 miles), advised this is seen regularly in most Acura's since 2004 (our other vehicle is a 2003 TL which we like), that it is a VCM issue and that the only solution he knows of is to speed up or down outside the problem speed ranges. Can this (chronic problem) be true? It seems hard to believe that Acura would have any clients buying a second time around. I joined this forum hoping for some insight and advice. Thanks.

We have a 2014 RDX with Tech pkg 3500 miles
Started to notice a slight vibration at low speeds around 25 mph under a light throttle load. Now we are getting a more pronounced vibration around 55 mph. I called our dealer in St. Paul Mn. And he said they have had other similar reports , and have one in the shop waiting for Acura to come up with a fix. At this point this shop doesn't know what the cause is or what to do about it? At least they acknowledge there is a problem, and they said they would contact me when they get answers. The problem is most likely in the VCM system....Dave

2014 RDX Vibration

I brought the exact vibration issue (2014 RDX) to my Minneapolis dealer. The mechanic acknowledged Acura is aware and Acura's solution is a drivetrain vibration dampening system planned for the spring in 2014. Said my new Acura would be fixed free, however, I am trying to confirm this is all true. The engine already has a dampened system. The cause of the vibration is the engine fuel economy system and shift timing.

Has anyone else heard of this planned fix?

I have owned a 2013 Acura RDX FWD for 17 months (11k miles) and I have experienced this dreaded vibration from day 10 (funny -> only 10 days of happiness)
I have been to 2 different dealership to complain about this problem and on both occasions, after driving with the tech foreman, and even after they have "felt" the humming noise and subtle vibration, I have been given the 'normal specs' crap. I even called Acura corporate to complain about this issue and I was given the same type of treatment. Basically they don't (or don't want) to acknowledge that there is a problem.

Yes, they issued a TSB for vibration in the drive train but my car is not included because it is a FWD. I just wished that there was a non-hacking way (switch) to disconnect the dreaded VCM because I would gladly give up 2 mpg if it means getting rid of this stupid problem.

This whole issue, together with noisy suspension, bothers me to no end; but I have resigned myself to the fact that I have 2 choices: Either 1. Live with it [have worked with self-affirmations but they dont seem to work] or 2. Trade it. I am still considering my options (lexus NX 200T or lincoln MKC 2.3T) but I can simply said that the way my mind is working now, I dont see myself buying another Acura in the future.
