First Start-up and Driver's side seat shakes when I put on the AC - Goes Away When Car is Warmed Up

[NJWeatherman]

2026 Mustang GT Premium, A10, 1400 miles.

When I put my AC on during the first start-up of the day and car is in park, my driver's side seat shakes. The shaking becomes less noticeable as the car warms up and I put it in drive.
If I turn my AC on after the car has been running for awhile, I don't feel the seat shake.

Anyone else experience this?

I have not.

Maybe take it to the dealer and make sure the seat is properly secured.

No , if it just started doing this definitely take it to stealership. If it always did this take to stealership. Goodluck

I'll be doing more testing to see when it occurs

I just took ownership of it just prior to Easter. I had the AC on one other time on initial start-up, and I noticed it. It happened again the other day. The weather has not been very favorable for the AC. I'm going to continue doing some testing. My first service is at 5k.. I'll bring it up to them then since they will have it to keep it a day or two to test it.
