PKSB malfunction Clean Sensors

I ran my 2020 Limited Prime through an automatic car wash last week and started to get a warning of the sensors need to be cleaned. The warning went away for a couple of days but just returned. They are clean so I wonder if anyone else is having this issue. my main concern is I don’t want the sensors misreading that there is an object and slamming in the brakes. I think that might have happened yesterday at a stop light. I was creeping forward and all of the sudden a beep and a red “stop” flashed up on the screen and brakes slammed on. I was going about five miles pes per hour. I was not that close to the car ahead of me and they were not stopped. No harm was done but I’m glad I was not rear ended.

 

That may have been it. They are fine now. ThNks
