Does use of OEM tire inflation kit require service if TPS is working?

[McQueen]

Took delivery on a new 2023 Mach-E Premium AWD 6.28.2024 (std range battery) that was built after 11.1.2022. On 9.19.24 the RT front tire showed only 35 psi on the screen, so I rolled into a WaWa gas station air pump and hooked up. IT DEFLATED THE TIRE TO 26 PSI BEFORE I COULD UNHOOK IT! (No sign it was broken!). So I used the OEM tire inflation kit for the first time to top-up the tire from 26 psi to 38 psi (w/a very tiny bit of the sealant before switching to the air-only input) and drove it 4+ miles home at speeds exceeding 50 mph. Tire didn't flatten and wasn't damaged, tire pressure sensors all appear to be working still (on-board system shows slight changes on all tires as it normally does while parked in my hot garage). So, I'm thinking the tire's valve and TPS monitor are fine. Do I really need to bring the car in for "service?"
Left messages at the dealership but haven't gotten any answers, yet.... By the way: love the car!

It would be fine.

If you just put air in the tire, it doesn’t need service. If you turned the knob and injected the goo, then it does need service within 48 hours to remove the goo.

FYI on the digital tire machines you have to enter the tire pressure with the +/- buttons before you hook it up. I think the default pressure is 26 psi so that might be why it let air out.

Thank you!

Thank you. No one at the WaWa air pump lined-up and waiting for me to be done could figure out why setting it wasn't working (so they thanked ME and left). Still waiting for a dealership call or message or email.... Only accidentally plugged the inflator into the sealant port for 20-30 seconds before seeing the mistake, so I'm thinking very little if any sealant actually was infused before I unplugged from sealant and plugged into air-only on the OEM inflator. No visible material/residue around valve.

I’m a little confused, did you turn the yellow knob to the repair position or not while pumping in air?

Yeah, I'm confused too. 20 to 30 seconds isn't "a tiny bit". I envisioned like 2 or 3 seconds.

Yeah, I did plug in and engage the sealant under the nail-in-the-tire icon. The 20-30 seconds was the time it took for me to put on my reading glasses (maybe a little less); which should've been done first!

Just spoke with my dealership's Service Tech on the phone. He said if the tire pressure monitoring system in the tire is functioning (i.e., showing the "normal" slight tire temperature variations the same as the other tires) and there is no "leak" (taking that tire down to -35 psi) while using it over the weekend, then it won't need any service. The Ford Service Tech said that the "problem" with any amount of sealant in the tire is that it coats the inside of the tire making it unable to be patched if it's punctured at some point later. (I think he used the words "too slippery" for the patch to hold).
Personally, given the huge weight of the car bearing down on it "heavy duty" Michelins, I'd never risk a patch anyway.
I was more than a little surprised that the Service Tech at my new Ford Dealership didn't reflexively schedule me for $ervice! After 13 years of my very nearest Ford dealership's shenanigans (don't get me started on my 2007 Mustang GT's "Smart Junction Box" experience$ with them), the new dealership's Service Tech's tone, patience, and assurances were refreshing.
Going to drive the car as much as possible over the weekend and keep checking that tire.
Thanks to all who took the time to weigh-in.

Patching a tire (which is removing it, putting a patch over the puncture, then remounting it), is the safe way to repair a tire (versus plugging it). There is nothing unsafe about having a tire properly patched.

I'll keep that in mind when it happens, thanks again. Just saw what a replacement tire costs.
