Tonight on 7/29/2023 after driving between 5-10 miles at night with very light traffic, my dashboard flashed a message telling me "Forward Safety system disabled. Radar blocked." After receiving this message and it clearing from the digital instrument cluster, a small triangle appeared with a exclamation mark. After driving between 1 to 5 miles further down the interstate the triangle cleared from the screen. There is no damage to the grill, or sensor, and no indication of mechanical issues as I was driving down the road. The grill and sensor both also have little to no dirt as I routinely wash my car each weekI have read through multiple other comments like me stating nothing whatsoever is on the front grill that could be obstructing the sensor. And like the other complaints, if there is no warning light, there is no code stored!

Whenever I am close to a Tesla in traffic or at a stoplight, my parking sensors go off. I believe that the frequency of my Sonata parking sensors is being interfered with by Tesla sensors. This could lead to unexpected braking in traffic. This problem has not been reproduced by a dealer or independent service center. It has not been inspected by the manufacturer, police, or insurance representatives. Warning sensors go off.

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!!!!!

GASES FROM THE DASHBOARD HEATING CAUSE A FILM TO FORM BETWEEN THE WINDSHIELD AND THE CAMERA. BECAUSE OF THIS, IN HEAVY DIRECT SUNLIGHT, LANE KEEP ASSIST TOGGLES ON AND OFF WITHOUT WARNING CAUSING UNINTENDED LANE DEPARTURES WITH OUT WARNING. ALSO, WHEN USING SMART CRUISE CONTROL, THE VEHICLE SLOWS TO A STOP BUT MAY CONTINUE MOVING SLOWLY EVEN AFTER DISPLAYING THE PRESS GAS TO CONTINUE SCREEN. THE AUTO HOLD LIGHT DOES NOT ILLUMINATE.

The contact leased a 2020 Hyundai Sonata. The contact state that the radar in the vehicle interacted with the radar in Ford vehicles. While parking in a parking spot there was a beeping sound detected. While at a stoplight with a vehicle in front to the side, the radar engaged when a Ford vehicle drove up. The contact stated while turning nearby another Ford vehicle the radar engaged and the driver applied the brakes. The Forward Collision-Avoidance warning light was illuminated. The contact called the local dealer, but the vehicle was not taken to be diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 6.
