2025 Toyota Camry — steering wheel vibration only at one highway speed

The car is smooth around town, but there is a noticeable steering-wheel vibration in a narrow highway speed range. It gets better again above that speed. Tires look normal at a glance. What would you test first before replacing anything? I would rather test this logically than replace parts. What would you check next?

If it were in my driveway, capture voltage while the 2025 Toyota Camry is actually failing — after it restarts you've lost the clue. Don't erase codes until someone who can help has seen them. If they can't show the line item, I assume it's hiding. I'd rather look cautious in this thread than stuck later.

It did steering wheel vibration only at one highway twice this week, both times after sitting. No change in mileage feel. Wrote this up on my lunch break.

Same neighborhood, different next step: Get a real battery/charging test on the 2025 Toyota Camry, not just resting voltage, before blaming a module. If the cheap test changes it, stop and reassess. On “steering wheel vibration only at one highway,” that was the fork that mattered for me. Keep sale price, fees, and rate as three different conversations. Climate here is different, so treat that as a local data point. That's my plan before I call anyone.

I wouldn't throw parts yet. Swap the cheap/easy piece first on the 2025 Toyota Camry and see if the fault moves. That's the branch I'd chase this week. I'd want that in writing, not as a promise. Video is ugly but it shows the hesitation.

If it were in my driveway, move a coil or plug on the 2025 Toyota Camry if it's cylinder-specific and see whether the code follows. If the cheap test changes it, stop and reassess. This is from a 2025 Toyota Camry in Detroit. I'd want that in writing, not as a promise. Happens in gear, not in park, for what that's worth.
