2020 Hyundai Sonata Lane Departure Problems

The driver seat belt pops out sometimes for reasons unknown. The speakers suddenly stop working at random times so I got lost while listening for navigation directions safely paying attention to the road instead of watching the screen for upcoming turns. And the biggest one, a few times I almost crashed into oncoming cars and guard rails because if the road has a dip the sonata decides to jerk hard to the side and overcorrect itself when lane assist is on. When the road is level it just beeps annoyingly loudly when it can't see the lines or you accidentally cross over it, but does not actively assist even tho active lane assist is on. This is a major safety issue!!!!!
