2015 Hyundai Sonata Collision Avoidance Problems

Forward collision warning is frequently inaccurately sensing collision even when no other vehicles are on the road. I am now afraid to use adaptive cruise control because I fear sudden breaking especially when merging lanes.

I had a safety recall on my car for the Smart Junction Box. I took the car to the dealership on March 9th 2022. They updated the software that controlls the Smart Juntion Box.

My scc an my ldws came on an my RPM an speedometer gauge flat lined on my way to work going 55 to 60 MPH I pull over as soon as possible because I was on a highway not passing anybody I turned off the car an waited a couple minutes thinking it was probably a glitch because I just got my engine replaced from the recall not to long ago an when I waited about 10 to 15 min my car refused to start an I couldn't take it out of gear an had 5o have it towed to the dealership

ABS and Traction Control warning lights came on, then went out the next time I started the vehicle. They then did this a second time. On the third time, they stayed on.
