Vibration at low RPM and idle

Vibration at low RPM and idle
I was wondering if this was normal and due to the extreme cold weather we have been experiencing lately in our area. When my 2007 HCH is idle (but not auto stop) there is a slight vibration. This vibration is felt on the steering wheel and very slightly throughout the car. Once I accelerate I find the vibration is still there from about 1000 - 1500 RPMS and once I go over 1500 it goes away. If I put the car in neutral when stopped then it does not do it so it seems to be transmission related. Is this normal or should I be concerned?

Re: Vibration at low RPM and idle
Any automatic will shudder slightly when stopped. It varies in intensity from transmission to transmission, and also tends to be worse before the car is fully warmed up.
I just happened to notice this on ours recently. Like you, shifting to neutral helps, seems to make it happier. Your symptoms don't sound abnormal.
One thing: when I switch to neutral, I'll keep my hand on the shifter, as a reminder, to avoid inadvertant roll-back or engine rev when it's time to go.

I vote normal.
All autos do this to some extent. In Drive, there is a load on the engine. Turn the AC on at idle, and it'll get worse. It's just that - load.
It can be compensated by increasing idle speed, but this wastes gas and increases engine noise in the cabin.
Little 4-bangers (and ours is quite little at 1.3l) just don't like it much. Also, a 4 cylinder engine is just not a smooth as a 6 or V8, nor as powerful, so it's more noticable.
I think the Civic Hybrid handles this quite well most of the time - much better than I thought it would, actually.
Shift into N if you like to "take a load off."
But keep foot on brake.

Thanks for the replies. I had a feeling it was normal but just wanted some second opinions. My wife has an 07 LX Civic and it does not feel the same at all in terms of the idle "load". But she has the 1.8 with a completely different transmission so that likely explains it.

I have this same problem. My 2008 is a nightmare in stop and go traffic. I find the vibration to be very annoying. I noticed that if I put the tranny in neutral and rev'd the engine, the rpms would spike down and vibrate... then the idle would come back up.

I have had the same problem. Dealer says it is a "characteristic" of the vehicle. I made a video on you tube.
Is this the same thing you are referring to?

Re: Vibration at low RPM and idle
mhaven98, thanks for your response, very detailed, and basically covers exactly what I have been experiencing. I talked to the dealer multiple times, and have escalated this, and sent the video to the Service Director, not manager, Director. He is contacting Honda today, and I hope to get more info on this. Maybe this is something they can fix with a software update, and if enough people complain about it, we can get it fixed.

Re: Vibration at low RPM and idle
It seems the dealers aren't explaining this quite right, it is a normal operating feature though. When you idle or take your foot off the accelerator while cruising, the ECM will often shut down cylinders in order to save gas.
My HCH does this at idle too and it feels just like someone removed a plug wire and I am running on 2-3 cylinders, which is one way the car gets the mileage it does. It is a bit disconcerting at times and if you are having problems taking off from a start because of this then there is a problem with the system and it needs to be diagnosed.
