22 RX 350 lane assist

I have a 22 RX350 and the lane assist always fights me and pulls me to the center line or crosses the center line. She has 35k on her and I’ve taken her to Lexus and they said she’s fine and within limits. I can’t ever have lane assist on with how much I fight her because I look like I’m driving drunk! This is my 4th 350 and I miss my 2019 she was flawless until a deer took her out. Rest in peace my old 350! Any ideas on how to fix this or should I try a different Lexus dealer?
