Brakes jerk or lock up when coming to a slow stop

[Let’s Gooo!]

I saw someone post it a while back but wanted to see if anybody has had this happen now that there’s more GX out there.

It’s annoying, feels like being rear-ended every time I come to a slow stop. Doesn’t happen when I have to stop suddenly.

A friend said it could be a rotor problem but this soon? I just hit 4,500 miles.

Possible you're experiencing the same symptoms in this thread?

GX550 Luxury + at the dealer for a new transmission (5k miles)

I experienced an unusual jerk in my luxury+, which made me think it might be a transmission issue. The dealer confirmed after a week, and a new transmission is scheduled to arrive in mid-November (on back order 👀).

Oh no

Yeah, sorry. Didn’t mean to scare you. Just remembered seeing that thread after reading your post and wanted to pass along the info. Hope your car is ok.

I have the same experience however it’s not the brakes I think, it’s the transmission shifting down to 1st gear late or sometimes when it comes to complete stop.

Its likely your transmission and not brakes. Slowing down to 1-3 MPH, my transmission noticeably hard shifts down to first gear causing what feels like a thud/jerk. Is what you’re feeling consistent with what is discussed in the other thread mentioned above?

I had a very weird (but great) experience after I took it in for service.

Basically they did the 5,000 mile checkup and called me to say the brake/transmission issue couldn’t be replicated. They asked if I could take it for a test drive with them to pinpoint the problem.

I did and it was gone, not happening anymore. I didn’t understand why or how it was fixed. They said all they did was the 5k service which included tire rotation.

So I guess it’s fixed. I’m happy but confused. Glad it’s gone.

Yes that’s exactly if it was older car I had to replace the trany. I’m sure there will be a recall.

 

[ralmassi]

I am sure it will come back mine does it about 50% of the time.

I'm baffled by all of the nagging issues with the GX, yet I haven't seen anywhere near as many issues with the new LC 250. What is going on at Lexus?

Different drivetrains, different drivetrain problems…. 6 cylinder vs 4 hybrid, 10 speed vs 8

LC 250 has different power train.

That’s why I opted for the 10yr/100k mile extended warranty. 1st model year will always have more issues. I luckily haven’t had any issues so far at 900 miles in, but it’s a small price to pay for the security in my opinion.

OK. And Toyota apparently got theirs right and Lexus fumbled?

I don’t own a LC, but your post got me curious so i went to toyota LC problems forum and it looks like they suffer similar problems with squealing breaks and tranny issues. See link below:

Prob not related but have you turned off the ‘Braking Assist’ in Settings? I remember it being super jerky with this setting on. Just a thought

Just had this happen for the first time today (13K miles). Was coming to a stop and it felt like a real hard downshift. I've had hard downshifts before in this vehicle, but this was noticeably wrong. Drove it around afterward, everything seems fine. Not sure if it was just a fluke or what. I also had the Hold feature on (I usually don't) and I kind of wonder if it was engaging too early or something. Still, whatever it was was hard enough to be disconcerting. The last time I felt a tranny act like that it was on its way out.
