2024 FE left wheel squealing in specific situations

Darn - I was hoping that was the issue. They serviced all my brakes today. I turned the auto parking brake back on to see if the squeal returns tomorrow morning.
Specifically, what did they do, when they ‘serviced all your brakes’ today?

Hi - sorry for the delay in responding. The service appointment record only says "Serviced rear brakes at this time. No visual signs of parts rubbing causing squeal. If squeal still present in the morning after rear brake service recommend having vehicle stay over night to be able to duplicate concern".

The appointment took about 45 minutes and that included a test drive so I don't think it was too intensive. The appointment was Monday - I reversed out Tuesday and Wednesday morning. There was one small squeal on Tuesday and nothing on Wednesday.

I don't know if the cleaning/servicing solved the issue but it seemed to help in the short-term. I will post again if the squeal comes back.
 
My LC is still doing it, this morning it was extremely loud backing out of my driveway.
Had service today and like others mentioned, they were not able to help at all. I have an appointment to leave the car overnight later this week so they can try and replicate it, but honestly I'm not that hopeful.

This is my only issue so far with the LC but it almost makes me not want to drive it with how embarrassing the sound is. Maybe I'll try some rock crawling in reverse next time.
 
I just noticed this for the first time this morning when backing out of my garage. Parked the car the previous evening after driving on wet roads during a light rain. The noise appeared to come from the rear of the vehicle when I gently applied the brakes.

The noise started while the car was backing straight up (i.e., wheel wasn’t turned in either direction) and worsened for a second or two when I turned the wheel to the left. It hasn’t occurred again today after several other instances that I’ve put the car in reverse and backed up.
 
We need a poll as to how many members this has happened to. But that’s too high tech for me.
I have sme problem 1st thing backing up. Took it in 4 1st oil change last week dealer could not replicate. Now where have I heard that before?
 
Are we talking about brake squeal here or something else?
Surely everyone knows what a squeaky brake sounds like, right??
I ask, because I had an intermittent AWFUL sounding harmonic scraping sound going on. I pulled off the front wheels and inspected the brakes and everything else. I pulled my dust shields back from the rotors to give a little more room (the noise sounded like a rock between the dust shield and rotor to me) and I have not heard the sound again. Not sure if I found the source of the sound yet, or not…

OP here. I have now taken it to the dealership twice and the first time, they thought that maybe it was the dust shields. So they clean those and the sound came back. Then they replaced the brake pads and it disappeared for a while, but then came back. I was pulling out of the garage this morning, and my wife was standing nearby, and we both clearly heard the squeal. Unfortunately, this not seem to be a brake issue in and of itself.

In reverse - beginning of the day - sounds like brake squeal to me

Yeah, in retrospect, maybe my comment was not clear. The squeal clearly happens when you apply pressure to the brake. But all of the typical things they do to try to remedy brake squeal do not seem to work.
 
Same issue here, only mine happens with the wheel turned to the LEFT(backing out of the garage or a parking space after the car has sat for more than a few hours).

Started happening 1,500 miles, currently at 2,500 mi.

I’m assuming it’s the same root cause regardless of left vs right?
 
(I apologize for copy/pasting my post from another thread, but this one seems more active.)

Has anyone considered trying to contact Toyota to escalate? Not sure how much it will help, but I submitted a video and details to them using the Toyota Brand Engagement contact form. Contact Us | Contact Toyota (scroll to the bottom of the page).

I also provided links to various threads in here that had the most replies. Maybe if more people do that, we won't have to wait years for a fix. (or maybe they will just forward my message to the dealership, who basically say it's up to Toyota and they can't do any more).
 
I’ve driven down some dirt roads this week dove hunting and it’s done the squeal 3-4 times a day the last 2 days. It has to be a dust shield issue but it’s only the driver side front tire that makes the noise which doesn’t make sense.

Mine did this fairly loud this week backing out of a parking spot slowly
 
Interesting to note that after experiencing this for the first time on September 16th, I began regularly hearing the noise when I backed up for the first drive of the day. Weirdly, the noise has completely disappeared and I haven’t experienced it in the last two weeks despite driving in a wide variety of environments (e.g., wet, dry, warm, hot, cold, high humidity, low humidity, etc.). I’ll keep an eye (or an ear) out for it as we are going to get much cooler and wetter weather this week, but the issue may have resolved itself.
 
To answer the questions so far, it’s definitely not the hybrid motor. That is a soft, high-pitched noise. This is a noticeable squeal coming out of the left wheel well.

As for brake pressure, it happens when I apply more pressure than less, and usually only from a cold start, and only when I have the wheel turned all the way to the right.

I suspect it has something g to do with those three factors: cold start, wheel turned to the right, in reverse. Probably some way the pad engages with the disc. Guess we’ll see. I just dropped it off at the dealership again this morning.

did you have any luck with squeaky brake fix?
 
Did replacing the pads fix the problem?
Update for anyone interested in the thread. I took it to the dealership and they confirmed the noise, then said that absolutely should not be happening and are replacing the brake pads. They speculated that the pads might be a touch off and therefore make noise when the brake is not fully engaged and it’s off a cold start. We’ll see if that does the trick. The pads come in Tuesday and I’ll get them replaced then.
Hello, did this fix the issue? Thank you.
 
I just went back to the dealer with this brake squeal issue. This time insisting on a fix, and not didn’t accept things look ok or all brake squeal. I gave them a string from this forum, which showed same issue with Lexus version of LC and the fix and parts list.
…basically new pads and shims. Interesting they told me all parts are on back order. I’ll use this forum again, thank you, showing them there is not a real back order others are accessing parts. I thought this might be another stall strategy.
