    Hey Guys,

    Recently bought a Prius Prime and the LTA is not working very well. It suddenly just shuts off and i veer off into another lane. Its not related to any settings (i'm well versed with how it works and under what conditions). I took it to the dealership and they were very hush hush about it....something about the can't discuss the details. I had a 2020 prime that worked really well so this is a big surprise...

    Anyone else with this issue?

    I have to admit that I’m a bit confused: what year are you talking about? ( for one), and why/how are you veering off into another lane if LTA shuts off? (For another).
    The only way I could do that in my ‘22 is if I was REALLY fighting the LTA, which, according to my owners manual, would cause the LTA system to disengage (ie: it won’t override my own input).
    Thus my confusion.

    This is in regards to a 2022 (also own a 2020). The LTA will veer off into another lane by itself....

    I turn mine off; because it's very annoying and bouncing the car between left and right lines, in the lane. I don't need a nurse-maid to tell my how to drive.

    It only works 32mph +. It's only intended to give the driver a warning, it will not keep the car in the lane by itself
