2012 Yukon Denali stock suspension. At speeds between 10 to 15 mph the front end sways left and right. I can see the front end move while driving.

[testdepth]

Front end makes no noises while this happens. I have done no recent work to the suspension or tires. This happens while driving straight at 10mph to 15mph and is very noticeable like the front tire might come off. Once at higher speeds it does not do this. Only noticeable at the low speed.

What might cause this or where can I begin to look?

Loose nut behind the steering wheel

I would start at the very front...as in that bowtie emblem....and get rid of it !!

But seriously I would start checking ball joint play and steering linkage play for wore out components.
This vehicle has given you a lot of trouble !!

Time to trade....
Let it become someone else's problem.

Man you ain't lying!!

2025 is the year of the 2012 Yukon Denali 6.2 repairs. Last week I had to replace the radiator. I finally got rid of all the other problems and this happens.

Motor mounts
Iridium plugs
Coil packs
Valve cover gaskets and grommets
OEM fuel pump and sensor
Crank Sensor
Temp sensor
EVAP charcoal box
EVAP purge valve
Radiator and both hoses
Oil pressure sensor and filter
Front brake pads

TBD what's causing the front end sway?

Have you had it up where you can check the front suspension components? If not, I would start there.
Put it on stands, on the frame, where front wheels are off the ground. Check play in tie rod ends, center link, upper and lower ball joints. See how they feel or if anything is loose.

Just put it in the air to look at front suspension. This is a 2wd Denali so no CV axles. I did not see anything obvious. All ball joints look good and not split. Lugs are tight. There is a small amount of play in both tires when trying to move the tires side to side to check the wheel bearings but it's minimal. Steering wheel does not move when this is happening.

No offense, but you may need someone with experience in suspension and steering to help you properly check components.
You need to put it on stands , on the frame, with tires about 6” off the ground. Insert a large pry bar under the tire and check play moving up and down, while watching ball joints. Moving side to side while watching tie rod ends. Also checking the strut components.
Spin the tires watching for any obvious wobble or warped look in them….sometimes belts will come apart and cause play.

If this is something you are unsure of , get someone with experience to help You look at it. What you are describing can be a number of things.

When was the last front end alignment? If it has been sometime, it may be worth having it done. Tell them to rotate tires from back to front and align front end. That should help some.
A good alignment tech should check all front end and steering components prior to alignment.
