Will brake hold feature cause more brake wear out?

Normally, your foot is completely off the brake before you apply on the gas paddle, but in brake hold mode, the brake is still on when you begin to press the gas paddle. Will that cause more brake wear out in brake hold mode every time you get the car moving?

I don't think so, you can clearly feel it disengage. I think the brake drag is very minimal.
Think about out how many times you apply your brakes a day, for me it's got to be at least 60 times a day. And that's taking a 5,000 pound vehicle and brining it to a stop at random speeds (sometimes high speeds). It's nothing for the brake pads to handle the demands of the brake hold function.

I've read the brake hold feature applies 80% of the brake power to hold the car. I agree with Double. I can't see it doing anything meaningful at all. I don't think it drags much at all.

Does the HOLD feature use the brake disc pads or does it use the parking brake? I know that if the HOLD feature stays on long enough (3 minutes?) it will set the parking brake, but I'm not sure which is actually holding the car.

Interesting but I would say they work together. I use the brake hold on some steep hills in Hot Springs to take pictures and it works great without any of those rare creeping sounds that I have heard..

Do I think this will necessarily warp the rotors any sooner? No. But it could. Do I think it is worth sweating over? No. I like the brake hold function, use it all the time. If I ever feel like I just pulled a fast stop, I click it off and let it roll a bit and drag the pads across the rotor. It makes me feel like I'm doing some good, whether I am or not.

I have always been told to NOT keep the brakes applied with full pressure while stopped because it will damage the rotors..... I am sure (hopefully) the Lexus engineers took this into consideration when they engineered this brake hold feature.
I have taken defensive driving instruction (high speed evasive maneuvers, skids, panic braking, etc.) on a race track with "street cars" and the instructors always said: "When you come in after driving the track DO NOT apply the emergency brake and keep your foot off the brake ..... just leave the car in park".
Let me tell you that when I came in from the road course you could smell the brakes burning on a Ford Crown Vic and Dodge Charger..... I wish I had a temperature gun handy to read the rotor temps.
