Rear Cross-Traffic Collision-Avoidance Assist (RCCA) Slammed on my Breaks to Save a Shadow!

[ILOVE2DRIVE]

Sorry for the long title folks! My 2021 Telluride slammed on the breaks and scared the crap out of us the other day while going to lunch. I saw a wide open parking spot. All the parking was nose in or backup to a tall wooden fence (example below). We were backing up and no where near the fence, but it was sunny and shadowy. Suddenly, light, sounds, breaks! The Telluride stopped on a dime! Nothing there, just the sun casting shadows. Has this ever happened to anyone else?

PS: I know, silly example of fence.

That's not how rear cross traffic assist works. It's based on radar detecting motion coming across the rear (from a pretty good distance, too). Perhaps someone was walking behind your car (or another car next to yours).

Nope, there was no one around and the lot was empty kind of like the photo. I guess it malfunctioned but that’s a bit scary and I’ll have to keep track of that.
