Vibration at idle

New MKC, 2.0 FWD, with about 460 miles. While stopped in "D" (as at a stop light), at times there is a noticeable vibration that I can feel mostly through the steering wheel. While any car is going to have some degree of vibration, about 50% of the time the level is enough to be irritating, especially in a vehicle that retails for > $46K.

Anyone have a similar experience? No need to complain if this a "they all do that" item.

I haven't noticed or felt any vibration to any degree really let alone to the point of being irritating.

Not here either. From P to R to D (change in direction) there is a bit more drivetrain 'bounce' than I am used to, even for a FWD. But nothing really raggy at idle. What is your idle rpm? Does it go away if you put in in N?

I am not finding any major vibration issues in Park or idle Drive for my vehicle.

I don't have a persistent vibration per say..but what I have is a little different. The first week I had my MKC and I hit the push button gear to take it from R to D, the car literally slammed into gear. I thought at first I pressed it wrong (idiot check, first time I am using a push button gear) and maybe pushed two buttons at once. It brushed it off. It happened again a few more times in the next 10 days or so. It did not happen every time I put it into a different gear though and then seemed to kind of go away all together for a month or so.

At that time(month into driving) I noticed a weird shift going in lower gear (going between 25-35MPH), it seemed to kind of hold back a little, not quite a hesitation, then would fling me forward (I literally move in my seat). Again this comes and goes and the push button gear problem now does not slam into gear but it kind of "shakes" like its going to stall (rough idle?) when I push a gear. Its brief but it almost feels like its struggling to go into gear. I notice particularly backing out of my driveway when going from the R back to drive. It also kind of shudders sometimes when I pull in my garage and put it into P.

The shifting between 25-35 is almost like a slingshot lately. It holds back then flings me forward into gear. It is more noticable than any other gear shift (although I feel my MKC does not shift as smoothly as previous cars I've driven). Perhaps just the way the EcoBoost engine works? Husband has 2013 Escape Titanium with 2.0L (I have 2.3 in MKC) and we don't notice it.

Sounds like maybe the Torque Converter issue. Mine has been doing that. There is a TSB on it. other owners have commented on it elsewhere in the forum. The Converter is replaced per the TSB. Or there is also a separate TSB to reprogram the PCM to deal with harsh shifting or shuddering between park and the drive or reverse gears. Mine is in the dealer now for this, as well as the heat/cool seats fix and Sirius fix.

No bounce upon shifting that I've noticed. Idle in D when stopped is about 800 rpm. When I'm experiencing the vibration, shifting into N reduces but doesn't eliminate it.

I did recall people talking about the symptoms of the torque converter and although some of the symptoms sound similar I am not certain that's my problem. My car never made a noise while shifting and although the push button gear probably started off slamming hard like described, that only happened in the first week or so. The push button gear "shudder" also comes and goes (or more accurately it stands out more at times).

Overall what stands out more right now is the "slingshot" shift in the lower gear. Just seems overly harsh and overall my shifts seem "more spirited" This is in comparison with 2006 SRX and 2013 Ford Escape. Maybe not a problem but just different?

That 800 rpm does seem about right. I agree with others that a dealer trip to reflash the trans software makes sense. In the meantime, I might suggest tuning the AC off to see if that changes the harmonics of the drivetrain enough to smooth it out-it will probably idle a bit higher rpm. If that helps, the dealer might be able to bump up that idle speed a little. Or maybe a motor mount is not tight enough.
