2017 Nissan Altima — dedicated winter tires or modern all-weather tires?

I'd want a measurement, not a hunch. Capture voltage while the 2017 Nissan Altima is actually failing — after it restarts you've lost the clue. Save the big job until that test fails. That's the sequence I'd use. I'd rather be boring and correct. I'd rather pay for diagnosis than a second guess-repair.

I went back under the 2017 Nissan Altima and it only happens after a heat soak, not on a cold start. That's my plan before I call anyone.

It did dedicated winter tires or modern all-weather tires twice this week, both times after sitting. No change in mileage feel. I already checked the easy fluid levels.

If it were in my driveway, a pressure test beats staring at a dry driveway if the 2017 Nissan Altima is losing coolant with no puddle. Save the big job until that test fails. Take it or leave it — that's what I'd do. Not trying to scare you — just skip the expensive first guess. If it repeats twice more I'll book time.

I wouldn't throw parts yet. Swap the cheap/easy piece first on the 2017 Nissan Altima and see if the fault moves. Save the big job until that test fails. If you share a photo of the worksheet, easier to sanity-check. Video is ugly but it shows the hesitation.
