I got 2019 NX300. I am trying to figure out if my Lexus behavior is normal during the lane assist cruise control.
When activated, it does not stay in the lane more than half of the time. It tries to wonder off the road than hits the lane, acting like a pinball.
Is this normal? If not, I may need to take it to the dealer.
I guess what I am wondering is how centered your car is in the lane when the lane assisted cruise control is turned on.

My 2019 Rav4 stays in the lane 90% of the time as long as the turn is not steep. Not sure why NX300 is not acting the same.

 

My 2019 model was built before Oct 2018. Does this model come with 'Lane Trace Assist' or 'Lane Departure Assist' feature or does it just come with 'Lane Departure Assist'? I think there is a big difference. Well, let me know how your 2019 model behaves after turning on that feature. Thanks.

 

It seems 2019 models should have both LKA (Lane Keep Assist) and LDA (Lane Departure Alert). For some reason, I think my 2019 only has LDA. This feature just basically alerts and turns the wheel retroactively instead of steering to keep you in the lane at all times. Could it be that LKA got disabled somehow? When active, I only see single lines on each side of the car on the front display, not double lines with an additional blue lines next to white ones....

Does anyone know if our car actually has LKA?? Would love to use it with the radar active cruise control for long trips.
