  BACK OVER PREVENTION: SENSING SYSTEM: CAMERA

  Hyundai Motor America (Hyundai) is recalling certain 2021-2022 Santa Fe, Santa Fe HEV, Elantra, Elantra HEV and 2022 Elantra N and Santa Fe PHEV vehicles. Due to a damaged printed circuit board, the rearview camera image may fail to display. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 111, "Rear Visibility."

  Risk: A rearview image that does not display reduces the driver's visibility and increases the risk of a crash.

  Remedy: Dealers will replace the rearview camera, free of charge. Owner notification letters were mailed January 14, 2025. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 271.

   Several times, including yesterday, my forward collision avoidance engaged by braking suddenly and strongly and INAPPROPRIATELY, almost causing me to be rear-ended. I was nowhere near the car in front of me, and fortunately due to traffic was traveling below the speed limit. This seems to happen whenever there is an overpass above the road. I have reported this to Hyundai, and they don't seem very concerned. Very dangerous. I would think there could be a software or sensor…

However, I pulled over and the sensor did not appear dirty. After awhile the sensor went off on its own. Then a few weeks late the front collusion safety warning appeared again while I was driving on the highway. The warning has not fixed itself. I cannot use my cruise control. I took it to the Hyundai dealership…

    Over the past 4 months, this car's safety sensors have randomly activated on 4 different occasions. The car will suddenly brake when this occurs, which puts me and the other drivers around me at risk of crashing. Each time, I've taken it to a Hyundai dealership for repairs. They always claim they can't recreate the issue and don't fix anything. I've provided the dealer with pictures and videos of the warning lights on my dashboard. It doesn't seem to help them diagnose the…
