Can you request Honda to bump the idle speed up a bit to stop vibration? I don't mind a 1-2 mpg decrease as long as it's not a huge decrease of mpg and it stops the vibration. Even if it meant signing a waiver form about mpg loss.
Can You request a RPM increase?

No. They can't program that. You'd have to use k tuner or the like.

4cyl/CVT seat vibration at idle. The Seats do. 4Cyl CVT.

What does the K Tuner actually do?

KTuner lets you change a number of parameters regarding your engine, power, rev limiters and throttle settings.

That's a normal part of the CVT.

It's the engine's RPM, not the CVT. When the car decides to idle at just a tad higher RPM, the car feels like a V8 Lexus. When the RPM drops, it vibrates like a 3 cylinder. A simple change to instruct the engine to never drop below a certain RPM, and the problem goes away.
I would take the MPG hit if I can have that. But of course Honda won't be allowing that themselves, they got CAFE to think about.

Both my wife's 2015 CRV has 3,000 miles and my 2013 Accord has 23,000 miles. And, both cars idle very smoothly for a four cylinder engine.

Would shifting to neutral alleviate the issue? I know the vibration isn't caused by the transmission, but rather the engine idling so low. However, on my 2000 accord, I had the same problem. Putting it in neutral would usually stop the vibrations. Just my 2c

There are vibrations with the 4cyl that have nothing to do with the transmission. Once my engine is fully warmed up, it will vibrate a bit at idle. Increasing rpm solves this. Again, this has nothing to do with the transmission and everything to do with the number of cylinders. That being said, I don't mind it.

the 'problem' is a Honda. they decided to go with a high displacement 4 cylinder engine. with their programming wizardry and engineering mastery they have achieved massive power (on 87octane) and exceptional fuel economy. an engine like this would vibrate to no end so they have a nifty oil pump/dual balancer shaft assembly driven via a baby timing chain bolted to the bottom of the block in the oil pan. without substantial motor mount changes this is it - try to enjoy the car for what it is - an awesome machine! feel the vibration and imagine all it's moving and turning parts in harmony doing what has to be done - get you to point B.
civics don't have as noticeable a vibration due to 1.8L. there isn't a balancer system at in the 1.8L AND that car only has two motor mounts lol! when you start going over 2.0L you feel it more an more and require a balancer system to reduce (not eliminate) vibration.
it will be very interesting to feel the new 2.0L civic and especially the 1.5L turbo civic.

1. Just put it in neutral as others have said.
2. I find using accessories that draw a lot of power -headlights, defrost, HAVC fan on speed >2 also causes the Ecu to bump the idle speed to power the alternator. Car idles smoothly in gear.

While I agree with what you wrote I consider this vibration to a blight on Honda. I frequently rent mid size 4 cylinder cars (Camry, Legacy, Fusion) and none of them exhibit the vibration that the Accord 4 cyl does. It makes Accord feel very unrefined.
Just pretend/imagine that you are riding a harley. Vibrate like sh1t at idle and smooth once moving.
The vibration can be noticeable, but for the price of the i4/cvt Accord that performs well, gets good gas mileage and should be a long term low maintenance vehicle it is acceptable. It is a budget Honda, not a luxury vehicle.
I love my i4 accord sedan (vibration at idle and all) - boringly reliable, great bang for the buck, and much more fun to drive than the Camry/Fusion (never driven the legacy).

Why are you crying because your car is vibrating? Vibrating is a normal Honda car characteristic. I rather take a vibrating car that is reliable than any other car brand that is spontaneously prone to break.

My 2008 I4 Camry vibrates even more than my Accord when stopped in gear. Shifting into N makes it go away.

Wow, even a Legacy? Yikes. I always thought Subies were the absolute worst for vibrations. Their flat-4’s rocking couple is far more harsh than the secondary balance problems inherent to an I4 engine, particularly larger displacement I4s. Ironically the flat-4 engine has no primary or secondary balance problems but that rocking couple is nasty.
On the subject of secondary balance problems and the need for a balance shaft(s) on larger I4 engines, has anyone noticed this idle-vibration in past 2.4-liter Honda engines? I never noticed it or heard it discussed. What changed with this latest engine and as Markus pointed out why do so many other car manufacturers NOT have this problem in their big I4s? They all use balance shafts too.
Lastly if increasing the idle-rpm solves the problem I can’t see that adversely affecting fuel economy. What percent of the time do we sit at idle?
