It explains it all...

http://townhall-talk.edmunds.com/direct/view/.f197b14/43

Ok, here are my findings... and here is my advice:

The problem has been determined to be the VCM (variable cylinder management). It's affecting LOTS of people to various extents (like from subtle to rediculous).

The VCM is causing the vibration. A poor design and malfunctioning of it rear mount hydraulic comensator. This crazy little thing is supposed to counteract the vibrations by adjusting it's angle... In some vehicles it's misfiring and doing a bad job. I'd say, design flaw.

Here's the thing.... Honda admits that it's vibrating, but says that it's normal for it to bump when changing from 6 to 4 to 3 cylinders and back.

What they will not admit is that the pulsing and vibrations never stop in some cases... ever...

Here's what I suggest:

Contacting the American Honda Motor Co. directly is futile... They'll run you ragged and then just tell you they cannot help you.

Your vehicle should be "bought back" from Honda.

Contact the BBB, Better Business Bureau auto complaints dept at 800-955-5100.

Be prepared to provide them at least 3 service reports that are identifying the problem. Get started now. Tell the service departments that your VCM is malfunctioning and causing a steady constant vibration, and that you'd like it fixed. They won't be able to fix it. There is no fix. They will tell you it's normal.

They'll contact Honda and establish a case for you. Honda will start to respond.

I hope this helps.

My CT has already reach 3000 miles , at the speed of 60-80 never felt any vibration. Not sure if the " your diagnose" is for real.

Not my diagnosis brother, just a cut and paste portion of the link above.

Not sure if I am experiencing the same thing or not. Sometimes at around 70mph or so I feel a shudder from the engine. Almost like the transmission is slipping or something. Not sure how to correlate it to VCM activity as I don't know that the ECO light really correlates to running on less cylinders. I haven't asked the dealer about it as I am sure they will tell me they can't reproduce.

I have a 2012 AWD CT with 9000 miles.

First ask this question, is this going to cause damage to your car and lessen it's life span? If you answer no then next question would be can I live with it? If your answer is no again, then sell the car by a Audi. If your answer is yes , I can live with the vibration then forget about it and turn up your radio.

I had a Chevy Pick up that would make a tapping noise for the first few minutes till the engine got hot. It was called Piston Slap, Chevy told me it would not do any harm to my engine and they were right I sold the truck with 150,000 miles on it and it still had the power and torque when the engine had 50 miles on it.

We are victims of the 25MPH or 40KM an hour shudder. Honda Canada has acknowledged the issue and created a new axle for a remedy. We had ours replaced 6 months ago and as of a month ago the shudder is back. We worry about resale even though Honda has extended our warranty.

As I posted elsewhere:

"A TSB was issued on August 30, 2016 concerning what Honda calls the "judder" at speeds between 20 and 45 mph.

It is Service Bulletin 16-066 which says to "update the A/T and PGM-FI software and replace the automatic transmission fluid."

They have extended the warranty portion that covers this if your car is within the age and mileage parameters. You VIN number is required to verify these things.

So far, it seems to have worked for me."
