Yup. My frame is showing way more rust and peeling than I feel it should after only one Michigan winter, always being washed and in a heated garage at night......here's a couple photos. 2014 Silverado Double Cab.

Same issue here. Mine are clean and clear. Go off randomly. The truck is going in for another issue today, will have them look at replacing the sensors. Mine started after the first drive through car wash I went through had an underbody wash.
