The contact owns a 2020 Tesla Model 3. The contact stated that while driving 75 MPH at night with self-driving assist mode, the auto high beams lights engaged three times within 20 seconds. The contact stated that the driver ahead of him then decelerated and veered to the side of the road because it appeared that the contact was sending him an alert through the activation of the high beams. Additionally, the contact was pulled over by a Police Officer. The contact stated that the auto high beam feature was distracting to other drivers. The contact stated that he was unable to disengage the feature. The manufacturer was notified of the failure and informed the contact that the driver did not have control over the feature. The vehicle was not diagnosed or repaired. The failure mileage was approximately 70,000.

Currently occurring with FSD Beta firmware V.2022.27.12 but the same has occurred with previous firmware versions also. Normal operation of the vehicle with the ADAS engaged puts the windshield wipers into AUTO mode. At times the windshield wipers are activated when the windshield is dry. It isn't raining or misting and there's nothing on the surface of the windshield at the location of the front-facing cameras. "No rain" occurrences seem to correlate with times when visibility ahead has low contrast and there are no highlights and shadows to sharply define the scene, (ie, a little "muddy"). Observed when it is overcast but not raining, around sunrise when the sun is low in the sky and the light levels ahead are relatively low and headlights aren't helping illuminate the road ahead, and at times there are high-contrast light and shadows immediately ahead but farther down the road there is mist or fog, creating the same low contrast lighting conditions some distance away. It is as if the ADAS is aware that the scenery is not sharply defined and is "wiping its eyes" in an attempt to gain a more sharply-defined view. Occasionally, but rarely in my experience, the windshield washer is also engaged. Having the ADAS activate the wipers at these times is not a safety hazard, per se, but it is distracting and concerning as it gives the driver the impression that perhaps the ADAS is malfunctioning. I've read in user forums reports from a fair number of FSD Beta drivers complaining that the wipers go on when the windshield is dry and the ADAS is engaged. I haven't observed the same when the ADAS is not engaged.

Activating FSD Beta Version 2023.27.7 switches the Display brightness to AUTO and to a brightness that is higher then the level set by the driver. In a darkened vehicle at night the Auto setting was too bright and a distraction to safe driving at night. I then spent 2-3 seconds with my attention away from the road ahead as I reset the brightness on the display screen to the comfortable level. After disengaging FSD Beta the display remains at the brightness level set buy the driver. The next time FSD Beta is activated the display brightness is once again set to AUTO and the distracting process of taking the display out of AUTO and adjusting the brightness to a level comfortable to the driver must be repeated. Activating FSD Beta puts the High beams into AUTO and allows the system to use the high beams when the Vision system requires it. This is excellent and works well. The display brightness is a driver preference and adjusting the display brightness is not needed for the vision system to operate effectively and should remain set at the driver's preferred setting so as to no be too bright and so the driver does not need to repeatedly adjust the brightness each time FSD Beta is activated.

I was driving to work on the morning of February 24th 2023 and it was raining. After some time, and while on the freeway, I noticed that my low beam headlamps icon (green telltale) on the center display was not showing. As I always drive with lights in AUTO, and since it was raining (windshield wipers were activated automatically), I expected the headlights to turn on automatically. I worried that I would not be seen well by other drivers, and had to navigate to the controls on the center display and switch the headlights from AUTO to ON manually. The headlights then turned on (I assume, since I couldn't see indications on whether they were on or off on the outside, but the green icon did appear after I pressed the "ON" button). Given that it was raining outside, relatively dark, and the windshield wipers were on, I would expect the headlights to be activated while in the AUTO mode. I have never had issues with this before, and wonder if this came from a software update. The switch to go from auto to manual lights isn't very easy to reach from the driver seat so I would expect the auto mode to work well so this situation doesn't have to happen.
