MASTER THREAD: Auto Wiper functionality, complaints, praise, etc.

Possibly. I repeatedly pressed the end of the stock as the spray was coming out and the physical feel of the button returning to its rest position felt normal. Without my touching anything, the pump would run for a couple of seconds, stop a couple of seconds, then keep repeating this cycle all while the wipers were at rest in the stored position.
Now I'm a little nervous to go anywhere since our roads are wet with slush/salt/sand covered surfaces.

I don't blame you one bit. Without a for-sure explanation and resolution, I'd be contacting Tesla if it were mine.
Mine does the same thing. It goes crazy after it’s been raining but has stopped. I just let it run wild wiping nothing for like 20 seconds and it turns off after.
Definitely the weakest link so far for me in an otherwise excellent experience. Auto function just isn’t good enough. Heavy spray on a busy road and I’m fumbling round trying to get them on.
Also I don’t have a washer function - the motor works but a drop of water at best comes out. It’s like the jets are blocked? Despite this I had a low washer fluid warning so I thought perhaps it was never filled. However I’ve filled it and still get nothing more than a dribble. I really don’t want to drive 2 hours to Tesla if anyone had a fix?
thanks very much

My M3 wipers come on with only 1 drop of water which is too sensitive now. They even come on heading into a tunnel over shading at the very entrance to the tunnel.

Regarding you washers not working: A while back someone discovered that the little hoses that go from the reservoir/pump to the wipers had become disconnected. As I recall, there is a Y where one hose splits to two (one per side), and a hose had come off (or never been put on in the first place). Easy fix. As I recall, you pop off the cover just behind the frunk storage compartment to access this.
Today I downloaded software version 2019.40.2.1. The wipers went from not wiping at all in torrential rain pre-update to hysterically wiping with the slightest drop ot rain post-update. Another car I own is a 14 year old Land Rover Discovery 3 where the rain sensor has always been working perfectly. Upon downloading the newest software release I got some nice text about the auto wipe function improving with deep learning and so forth, but in essence it seems that it boils down to Tesla having installed a crappy sensor as the aforementioned Discovery rain sensor has been working fine for the last 14 years without any learning whatsoever 
You should get some RainX windshield washing fluid. The orange stuff. They are amazing and I never use anything else. Most of the time you don't even need to use the wipers.
Autowipers are still terrible on 40.50.1. I have noticed one thing though. It may be a side effect of the car's aerodynamics more than anything else. Next time you are driving in misty conditions, take a look at the top of the windshield where the cameras are. You will probably notice there is almost no water spraying up there for the cameras to pick up. Not sure if there is a software fix for that one...

Yeah, I’ve noticed that too. It’s drier near the top. I keep a spray bottle in my cup holder. When this happens, I reach out the window and spray at the cameras.
That's an interesting solution but I guess do what works? Haha.
Now that I have noticed that it stays drier at the top, I am sad to realize that the autowipers will probably not get much better because if there isn't water getting on the area covered by the cameras, there really isn't any way for the cameras to know its wet. Not really a software solution there...
It will do it automatically, how accurately it works is a matter of huge debate.
The new neural net wiper update was sent in the holiday update, it's supposedly supposed to be a huge improvement.
The recent wiper update has worked wonders. Now you can put it in auto and leave it. Just remember to shut it off when you enter a carwash
Or when you park in a garage - every time I forget to disable auto-wipe, it will do so when I put the car in reverse.
Neural net or not, "one setting fits all" approach will NEVER work for the entire population of Tesla owners.
Some prefer more frequent wiping action, some less so.
Some have applied RainX or similar products to their windshields, some did not.
Some live in climates with rain and ice accumulating on the windshields (when wiping is ill advised), some do not.
A far simpler approach is to regulate the frequency of wiping manually, so suit your preferences and conditions.
You can semi-achieve that by pressing the turn signal stalk button in once (for one wipe). Then set the frequency UI pops up, and you can adjust it manually.
HTH
