Front parking sensor warning, at random
This started Monday, and has only gotten more frequent.
When slowing/stopping, even if there's nothing in front of me but an open intersection, my parking proximity sensor freaks out and goes to the most distant warning level.
Nothing has touched the front bumper, all the sensors look fine...suggestions?

Use a soft bristle toothbrush to clean all of the front sensors - it might help.

The only time I've had an encounter like that is actually in the winter, when the snow/ice seems to cover the sensor(s) and sets it off, driving or not. Scares the living $*** out of me when it does though.

Looks like I'll bristle them, gently, tonight when I get home. It was ultra-buggy around here a few weeks back...as in, the nose of Silvia looked like I'd just driven for an entire tank of fuel through farmland, at speed, near dusk. However, I'd driven a whopping 30 miles to work, in town.

Woo-hoo!
Thank you, forum-folk! I couldn't find a soft enough bristle brush to do it, but I cleaned all the front sensors with Windex, making certain to give it time to soften anything up.
Sure enough, no more false alarms.
Yay!!!

The sensors CAN go bad. I had one go bad on my LS430 and it presented the way yours did. Glad it was just bugs!

I have a 08 LS460 and have just starting having issues. This has been an unusually hot summer in the DC area and on 95+ degree days I receive the warning if I am in stop-n-go traffic. Once the car starts moving up to 30 mph the warning stops. We took a trip south a month ago and the temperature reached 102. We stopped for gas and the warning came on when I started the car. Once I started driving and the wind cooled the sensors down the warning stopped. I don't think I am going to spend any money to address this as long as it only happens in extreme heat.
