Camera System problems of the 2020 Hyundai Tucson

The backup camera in the 2020 Tucson ultimate is blurry, creating a serious safety issue. We have taken the vehicle to the dealer repeatedly with this complaint and although the service advisor agrees, Hyundai has refused to replace or repair the camera. Note that there are many of the same complaint that can be found through a simple internet search, but apparently Hyundai refuses to acknowledge and repair the issue. Both the driver's safety and the safety of others are at risk, since it's not possible to see clearly what is behind the vehicle. The problem has been confirmed by the dealer and the dealer requested a replacement backup camera, but Hyundai declined authorization for the replacement. Federal regulation that went into effect in may 2018 requires that all new vehicles must have a backup camera. Surely the backup camera must be usable, as opposed to just existing to satisfy the legal requirement? this camera is so blurry it is barely usable. We had this exact same make and model from the 2016 model year and the backup camera was crisp and clear, so this is definitely an issue with this particular model year.
