NHTSA Complaint #11535290 — 2020 HYUNDAI SONATA

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!
