My parking/backup sensors are not working. We're pretty sure they used to work, but we haven't had the car very long. We asked at the dealer when we stopped to pick up our plates, and they said it didn't look like we had any sensors (not visible), but we learned later that they are integrated into the bumper for 2021. Is there any trim package on the 2021 Santa Fe that does not have the parking/backup sensors? I'm guessing not. Thanks.
