Rivian Highway Assist Problem: Pulsing and Brake Tapping

[Rivian Mom]

Has anyone else felt a pulsing feeling when using assist mode in their Rivian? It’s much worse in All-Purpose mode, probably since all four motors are active.

This happens in daylight, with no shadows or cars nearby. It's also the first time it'd be acting this way.

I’m not too concerned about the motors’ behavior. It’s just irritating when the truck keeps tapping the brakes on the highway. It basically makes highway assist pointless.

Yesterday, during a long drive, I turned it off for a bit, then turned it back on, and it worked normally again. So for this week, I'd just keep an eye on it for any developments. Hoping it's back to normal for good.
