Hey Everyone,
I have a 2010 Edge, and recently the RPA alarm goes off when there is nothing behind you. Sometimes it is constant, other times it is a few chirps a second, or once every couple seconds, there is no consistency to it. I have washed the sensors, made sure they were not scratched or knocked out of their positions. I made sure that all 4 sensor are clicking when the car is in reverse, which they are. No service lights come on, on the dash. I turned the RPA off, but it does turn itself back on. I haven't been able to find much online about it. Any ideas?
