Intermittent shaking at red light

2014 Yukon 6.2

Slight vibration\shaking when at idle coming from the front end. Can feel it sometimes and other times nothing. Mechanic couldn’t recreate the shaking. Any ideas what it could be?

A few guesses: engine misfire, bad engine mount, throttle body needs cleaning.

original owner? bought it used?
I know on mine I changed out the broken, blown out fluid filled motor mounts for solid rubber hummer mounts
as such occasionally now there is some slight vibration at idle, no biggie just get to feel those ponies a little better

Welcome to the forum from Oregon.

I am assuming, I hate doing that, there is no CEL?

How long owned? Work done recently? Age of tune related components? Maintenance work needed or skipped? Like @Fless said.

I had intermittent vibration when idling/stopped. Then my car started shutting off when coming to a stop. Turned out to be a couple broken teeth in the timing gears. Had to replace the whole thing. wasnt cheap but shes running great now.

Bought it used a couple months ago. Pretty clean all the way around for the midwest. Went through that carbravo inspection prior to buying it at the dealer. My mechanic took a look also. No check engine light and drives good. Only that slight vibration and feels like it needs an alignment.

What makes it "feels like it needs an alignment"? What is it doing?
