Brakes jerk or lock up when coming to a slow stop

I had my 10,000 mile checkup yesterday and brought up that I’ve been feeling the downshift again.

They ended up doing a recalibration on the engine and transmission computer.

The downshift is gone for now but he mentioned that if it returns, like it just did about a month ago (around 3 months after my 5k checkup) to bring it back because Lexus is releasing an actual repair for this problem soon.

Makes me think it’s probably going to start doing it again sometime in the future.
 
I already posted this in a different topic, but I wanted to share it here just in case you miss it.

03/30/2025 - I confirmed with my dealership that Lexus has released a new transmission program to address the downshift issue for 2024 models. If you own a 2024 model, you may want to check with your dealership about this update.

For the 2025 model, Lexus has not released a new program yet. According to the dealership, the codes for the 2024 and 2025 models are different.
