I have a 2018 Ford Fusion Hybrid. Yesterday, while parking, I noticed the back up camera sounded... Off. Normally, as you get closer to the other car, the sound is more high pitch beeping out of all speakers, but yesterday, the sound seemed like it was only coming from the driver side, and it was lower, like a heart monitor beep rather than high pitched. Does anyone know what's wrong or have any advice on what to look for?
