The contact owns a 2019 Hyundai Santa Fe. The contact stated that the check Forward Collision Avoidance warning light was illuminated. While driving at various speeds, the vehicle veered into oncoming traffic. The vehicle was taken to the local dealer where it was diagnosed that the sensor in the windshield had malfunctioned. The vehicle was not repaired. The vehicle was taken to an independent mechanic who stated the windshield sensors were working as designed. The manufacturer was notified of the failure and referred the contact to the local dealer for assistance. The failure mileage was approximately 69,550.

12/26/2021 Driving on I40 E between Santa Rosa and Tucumcari using adaptive cruise control (SCC) at approx 68 m.p.h the brakes were harshly applied which resulted in the vehicle rapidly de-accelerating from approximately 68 m.p.h to approximately 5 m.p.h. (There was a warning displayed on the odometer panel). no vehicle or other obstacle within eyesight to the front, side of rear of our vehicle. Vehicle resumed driving on cruise. No warning prior to the event. Vehicle was taken to the local Hyundai dealership on 12/30/2021 for diagnosis, the mileage was 21066. The technician reported no DTC's found and suggested it might have been caused by the windshield mounted "dash cam", the "dashcam" was not in a position where it could possibly interfere with the vehicle camera, (it has been in the same position since vehicle purchase and remains in the same position today), possibly some critter that ran out in front of us and we did not notice it or maybe a big bug flew into the vehicle. also there was no obstruction to the forward vehicle radar. The vehicle was not road tested. This fault since the first instance has not happened again. this fault has been noted by other owners on various Hyundai owners blogs. This vehicle has FCA + Pedestrian, SCC, LKA.

"FCA" system disabled radar blocked" error came on while test driving on 3 separate occasions but no diagnostic code recorded, prior to taking possession they replaced a camera they thought to be the cause 11 days later during a snowy morning I got the same error again. Again it didn't register a code and I was told by the dealership no code, no problem. Spoke with Hyundai customer relations and was told I have to take it back to the dealership for them to diagnose it, and the condition has to be reproduced for them to note the error but We have not had snow since that morning therefore the system error has not reappeared. The likelihood of being able to reproduce the circumstance during business hours and be able to get it to them to witness the situation is minuscule at best. If this safety feature is deactivated when something as simple as a snowflake blocks the sensor then it isn't really a safety feature. The safety features contributed to my decision to purchase this vehicle (Nov 1st) but all I am told was the radar was blocked and therefore caused the deactivation, but again how can something as simple as a snowflake cause this error and the manufacturer not address this as a safety concern.
