Blind Spot Detection problems of the 2020 Tesla Model Y

In Tesla’s from Model Years before 2021, the side “repeater cameras” that are rear facing suffer from a light-leak of the blinker. There are three small holes in the pcb circuit board that allow light from the blinker to leak into the camera at night. Tesla subsequently fixed this problem, first by applying a sticker over the holes in the circuit board, and later by redesigning the part entirely. But this “light leak” problem exists on hundreds of thousands of cars. There are two problems with this: 1) Tesla has now changed their “autopilot” and “full self driving” software to a Tesla vision system that only uses cameras for the autopilot features, including lane keeping and lane changes. They no longer use ultrasonic sensors or forward looking radar, even though it is still installed on these cars. This reliance on vision makes it impossible for the Tesla side facing cameras to see when the blinker is turned on. This can result in unpredictable behavior when changing lanes or turning at night with autopilot engaged, including unpredictable or erratic driving where the car abandons a lane change mid course and swerves back into the lane. 2) even when autopilot is not engaged, the blind spot monitoring in this car consists of a pop up window on the center screen showing the side view camera when the turn signal is engaged. At night, with the blinker on, the driver sees a bright light flashing intermittently in the side view camera. This is very distracting and potentially hazardous to the driver. Tesla has refused to replace the cameras on my car under warranty because they state the cameras are “neither a defect of materials nor workmanship” and are an “expected condition based on the inherent capability of the camera design”.

When activating the turn signal at night, the blind spot warning image will display a glare that obfuscates the view of approaching vehicles.

When you turn on the either signal at night you can not see a clear picture on the blind spot camera's, they have a red haze on the display. It get so bad sometimes you can see anything. It looks like it's caused from the camera and turn signal being in the same housing. I have video I can send you.

Blind spot camera is unusable at night due to bleed through of light from turn signal.

Turn signal causes excessive glare effect on the side repeater cameras during nighttime use. Driver is unable to view blind spot camera feed properly when engaging in a lane change.

Side cameras have terrible glare which make them useless.

Backup camera appeared in on screen window as usual when I put the car in reverse to back into my parking spot. The camera looked clear and trajectory lines moved appropriately when I turned the steering wheel. However, main backup view in center of screen did not update as I moved the vehicle backward, it remained on a static, still frame of video. I reversed into a low fence post that I knew was behind me somewhere but could not be seen when looking out the rear window or using any of the mirrors. I usually look to the backup camera to show me where this post is and help back up close to it. There is a large blind spot behind this model of car that is well covered by the camera, but now that is has happened to me I have found many reports of the issue happening to others.

I realized that Model Y 2020 doesn't not have pedestrian warnings speakers even though my car built is from 2020 (between June-August). I took this delivery of Model Y in early first week of September. I am wondering NHTSA mandate this law in September of 2019. Since my car do not have even produced in 2020. I am really concerned about pedestrian popping out from no where. There were some times I almost near miss pedestrians. This mandatory feature could have helped.
