2023 Rivian R1T — steering wheel shakes only under highway braking

I wouldn't throw parts yet. Write temp, speed, and in-gear vs coast when the 2023 Rivian R1T does it — then decide on parts. If the cheap test changes it, stop and reassess. If it doesn't change the out-the-door or the repair estimate, it's noise. If it repeats twice more I'll book time.

I'd want a measurement, not a hunch. Loaded-suspension checks on the 2023 Rivian R1T catch play that a wheels-hanging inspection misses. Save the big job until that test fails. If you share a photo of the worksheet, easier to sanity-check. I'd rather be boring and correct. I'll poke at it this weekend.

This is usually cheaper to test than to guess. Get a real battery/charging test on the 2023 Rivian R1T, not just resting voltage, before blaming a module. That's the branch I'd chase this week. Just my two cents from doing this recently. Make the next action something you can finish this week. This is the version I'd tell a friend.

Start with the test that can prove you wrong. Write temp, speed, and in-gear vs coast when the 2023 Rivian R1T does it — then decide on parts. If the cheap test changes it, stop and reassess. A shop burned me once by skipping that step. No warning lights, which is why I'm documenting it.

Intermittent stuff lies if you only catch it once. Loaded-suspension checks on the 2023 Rivian R1T catch play that a wheels-hanging inspection misses. Save the big job until that test fails. On “steering wheel shakes only under highway braking,” that was the fork that mattered for me. Had a similar mess a couple years ago and that's what finally sorted it. This is the version I'd tell a friend.

Tried a second charger / second scan and the story on the 2023 Rivian R1T didn't change. Not interested in a five-hour wait for a shrug.

Post the numbers (or the code) and people can get more specific. Only after sitting overnight so far.
