What could be the reason for the 2022 S90 suddenly shifting at 3000 RPM?

It's really frustrating. Sometimes it's just the sensors acting up. I asked the dealership, and they said it's normal at low speeds. I guess they can't figure it out either.

Are you using the sport mode?

I've encountered similar situations before.

I don't know why, but after turning off the engine and locking the car, it was fine in five minutes.
