and I am not a happy camper!
In fact I am royally pissed.

The braking injured my right ankle and knee just an hour ago!

How do I disable ALL of the Pre-Collision System/Braking?

Should be able to find the information here:

See the "Changing settings of the pre-collision system" section on pages 176 and 177 of the 2024 LEXUS ES250, ES350 OWNER'S MANUAL USA AND CANADA ONLY. If you want the pre-collision system (PCS) turned off for each time you drive, you have to turn it off each time you restart your ES since the PCS is automatically turned on every time the ES is started.

I don't know the circumstances causing the injury causing braking event but you may want to consider changing the sensitive of the PCS to the lowest sensitivity setting/warning timing since that setting is retained across restarts.

That said, you really need to consider the the utility of the PSC in preventing or reducing the seriousness of an accident. In some rapidly developing potentially serious accident situations the PSC will have started braking before even your fastest reaction can start depressing the brake pedal. It can really save your bacon when a developing dangerous situation momentarily escapes your attention. You're already behind the reaction curve when that big old BRAKE flashes up on the Multi Information Display and (if equipped) the Heads Up Display.

How did it happen? I want to learn from your mishap so it doesn’t happen to me!

The pre-collision system can be a violent shock designed to immediately and abruptly stop the car. It has actually startled me a couple of times, but without injury. One time was backing out of a hand car wash stall. A person was walking to the office to presumably buy some tokens or something and I didn’t see them. It sounded like a loud crash, but was just the braking system “slamming down hard!” The other time was in an underground parking lot, driving pretty slow, looking for a stall with my head turning back and forth and a kid ran out in front of me. The parents yelled to the kid, but I didn’t hear, cause the acoustic windows do a great job of giving you a quiet ride. Anyways, loud BANG. I wouldn’t have hit the kid anyways, but the automatic system is very sensitive. I could see the angry parents trying to tell the kid to walk with them and not run around with cars around.

There's different systems controlling emergency braking for forward and reverse travel directions. The pre-collision system controls forward travel emergency braking. For reverse travel, the Rear Camera Detection (RCD) system controls pedestrian detected emergency braking and the Rear Cross Traffic Alert (RCTA) system controls cross traffic vehicle detected emergency braking.

Saved my butt several times when some moron walks behind your car when backing out.

After the first shock, who doesn't back out of spots like a 90 year old grandma when in shopping mall lots

This system avoided me minor damage to the car and another 2 or 3 times when backing out of mall parking slots, etc.
I’ll never be without it again—-ever. It’s one of the best features of my wonderful car, along with Intuitive Parking Assist that’s also indispensable for me, especially now, in my “declining years.”🥴

Sow how did OP sustain his injuries?

I’ve never been injured by it but it scared the hell out of me the first time I experienced it. I was at a hand car wash and was backing into position for them to dry, vacuum, etc…..my F Sport. There was a guy behind me telling me when to stop backing when the system kicked in. He never knew it activated but I sure did.

Curious how you were injured with a seatbelt on. If the seatbelt did not prevent you contacting any surface in the car then there might be an issue with that system.

He probably caught the edge of his brake pedal twisting his ankle while the car jerked to a stop?

Sometimes we never get the rest of the story. Where's Paul Harvey when you need him?

I'd rather have slightly sore body parts than crumpled sheet metal or damaging another person or their property.

Am I the only one that finds rear visibilty poor on the ES350? The reduced height of the rear window makes backing up a chore. I feel like I'm looking thru a peep hole compared to my old Avalon. This is my first car with a rear camera which helps but I wish the rear window was less slanted and taller.
