About 4 weeks ago I got the 2025 Prius Plu-In Hybrid XSE Premium. At about 66 miles on the odometer I noticed that there is a scratching/grinding-ish sound and pedal sensation when the car transitions to friction braking. If I press the pedal quickly it goes straight into friction braking, and I hear/feel it. This is only heard/felt at low speeds (20MPH or below). This is NOT ABS going off. I know what that feels like, and have experienced it in this car as well. I took it to the dealer and they claim it’s normal. They said pads and rotors look fine. However, I tried another Prius on the lot, and it does not behave this way. Anyone else here experience this? My previous car was a 2022 Lexus ES300h, and it did not have this issue with brakes.
My Prius gets that way every time it has sat parked over a rainy night. I fix it, the next time I drive it, by shifting to Neutral for my first 3 or 4 stops. That rubs off the flash surface rust that has formed on the rotors, making the grinding/scratching/vibration.
