2016~2023 Brakes

Hello everybody, I have two Mazda cx-9, one 2019 and one 2021. Both signature trim. The 2021 just surprised me with fading front brakes by driving through Bay Area hills. No hard or fast driving. Anyone has similar experiences? Just got it checked by brake shop. Everything is good!? They couldn’t tell me what to do but said high performance discs and pads would improve it. Also the brakes are somewhat under sized for a vehicle of this size/weight.
Thx
