2020 Hyundai Sonata Collision Avoidance Problems

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!

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.

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.
