2021 Toyota Camry Lane Departure Problems

When I do these checks I have my hands lightly on the wheel ready to correct the car when needed. The lane control assist tends to stay to the left of the lane, crossing over the left side lane markers, it also tends to head towards the right side of the lane, crossing over the right side lane markers without compensating. At times it does compensate but it causes the car to go back and forth in the lane without settling out. There have been times when the car is steered to the right with no compensation and without my correction would have gone off the road. The lane warning system doesn't always work. If I did not have diligence when using the system I would no doubt have gone off the road and crashed. The dealer has not checked the car, they say this is how it works even on their personal Toyotas. These problems have been prominent and have existed since the purchase of the car in 2021.
