MYP 22 accelerator pedal has an intermittent vibration

[Jsrconst]

MYP 22 accelerator pedal has an intermittent vibration. It's a ratcheting or grinding noise felt and heard in the pedal. I can't get it to reproduce, happens sometimes when letting off on the pedal and in a downhill direction. It is a drive by wire, what would be connected to the pedal that would cause a noise and grinding vibration. It doesn't happen everytime I drive. I think the noise is lasting longer now. Is this something I should be concerned with?
This car has a lot of rattles when you close the drives door the two passenger doors rattle. I have shaken them from the inside and they don't appear to be loose.
Thanks

Its the brake pedal doing that by blending in physical brakes over the regen, if you really hate the sound you can disable the setting “Use friction brakes when regen is limited”. Only thing is your regen won’t be the same strength with every drive and has to warm up for max regen.

That is great to know its normal, and I won't need to worry about it.

That got me as well when I first bought mine. It really is a horrible sound! @adc65 is right. I disabled that setting and all has been good ever since.
