Default 2019 Yukon XL Denali Adaptive Cruise control issues

I have had issues with this system being harsh on the cruise control on down hill. Hard braking around corners (75 mph set and braking down to 58 mph around a corner), Hard braking at night (75 mph set and braking down to 60 mph on a straight away.) System disengaging for no apparent reason. I upgrade the brakes to the factory Brimbo's (love them!), but I don't think the Adaptive Cruise Control software is corrected for the increase braking capacity. All in all I hate the active cruise or adaptive cruise. I understand the dealers can't or won't turn it off. I the problem isn't corrected I am tempted to lemon law it. Any work arounds for this issue?
