Automatic windshield wiper erratic behavior with software update 2021.4.15

Hello:
After I downloaded the software update 2021.4.15, the automatic windshield wiper turns on without any rain or moisture. Anyone else experiencing the same?

Yes, something similar happened the other day when I went under a freeway overpass. It was a clear sunny day, but the wipers turned on just after going into the shade of the overpass. Tesla will get it figured out.

Not having that problem, but auto hi beam is not working. Trying to get it to work causes multiple main screen crashes and reboots. Ranger coming tomorrow.

Is your windshield clean?

Is your windshield clean?

Yup.

Which model Tesla? I have 2021.4.15 in both our S and 3 and haven’t noticed the issue. I have had occasional unexpected wipes before but not related to a particular software version.

Must be Tesla’s “new and improved” wiper software

last time it rained in the vicinity of my car, it rained everywhere, not just on the windshield
Maybe they're using the other cameras to see if its rain or spray etc - I thought Green was brighter than that.

Yes, windshield is clean. It does not happen all the time. Did not happen yesterday. Three days ago, wipers came on nonstop, as if I was driving in the rain. Both days were similar, no rain or moisture.

Well, the Ranger came yesterday. He confirmed it is a software bug and that Tesla hadn’t seen it before. He offered to do a factory reset and reload if I wanted, but warned that this would erase all my settings- especially Homelink. We decided to wait and see if the next update cleared the problem, and if it doesn’t he will come back and reset. While he calls it a bug, I believe it is a corruption of one of the files. Not a serious problem, as I can always run the lights manually. Unlike what some people say, I have excellent service from Tesla, especially the Rangers, far better than any other company.

Having this issue also. Had my client in the car telling him how great Tesla’s are then it goes off.

Ver. 2021.32.22
10/26/21 Similar bug; very annoying in light mist. If "mode 1" enabled, wipers run intermittently even if windshield dry! Then I have to switch to "off." When mist accumulates, must turn "on"! (On a "normal" car, I could just flick the stalk; on a Tesla this method is not available.) Now that, in CA, seasonal "rain" has resumed, this is a real P___ in the A___!

Strangely, (and I don't think immediately after an update) I got in the car one day and the wiper (which I leave in mode 1) started "wiping" grit over a dirty windshield.

I will make sure my side cameras have cleaned lenses, but I recently had the car washed.

On a "normal" car, I could just flick the stalk; on a Tesla this method is not available.

Press the left stalk button once, half way, will activate the wiper for one wipe. press it fully, i.e. pass the click, will add washer fluid.

mine seems to be on a go slow --- can be bucketing down and its still thinking about a wipe- resoprted to 4x speed rather than auto --- used to be reliably judged - not just now --- any suggestions?
