A friend of mine made a complaint once about what sounded like brake squeaking/squealing noise when the car slows down, even with just regen without him pressing on the brake pedal. Doesn’t matter if the weather is warm or cold. He thought letting off the accelerator pedal does NOT engage the mechanical brakes? I’m not even sure if it’s the brake that’s making the noise. He has made an appointment with his SC so hopefully he'd get it sorted out real soon.
Sometime last year, Rivian added "blended braking" which is where the car will automatically apply the brakes as needed in addition to pure regen. This option is on by default however you can turn it off. The thought here is that if regen is limited for some reason (battery is cold, you've been going down hill), the car will behave consistently by applying the hydraulic brakes - typically the rear brakes (which are the smaller ones).
I turned this feature off as I prefer to know when my brakes are being applied because:
1. Blended braking will increase brake wear which is expensive to replace.
2. Slight application of the physical brakes will create heat and reduce overall braking capability.
