2023 Toyota Rav4 Lane Departure Problems

Your car is displaying multiple warning messages indicating malfunctions in the safety systems: the forward collision avoidance system, parking brake, and secondary collision prevention system. Additionally, the all-wheel drive system is also showing malfunction warnings. These warnings suggest that several electronic safety and drivetrain systems need diagnostic evaluation and repair.

Your car's lane-keeping assist system isn't staying centered in the lane — it drifts left across the left line, then overcorrects and drifts right across the right line, sometimes jerking back and forth without settling. There have been instances where it steered right without correcting, and you'd have gone off the road if you weren't actively steering. The lane warning system also doesn't consistently alert you. This issue has been present since you purchased the car in 2023, and the dealer says this is normal behavior. The fix will likely require the dealer to recalibrate the camera sensors that detect lane markings, or potentially replace the lane-assist control module.
