NHTSA Complaint #11688524 — 2023 TESLA MODEL Y

The Full Self Driving (Supervised) ADAS in this vehicle will react to shadows on the road and can put the car or other cars at risk. We have had multiple instances where, on a sunny day, the car will react to shadows cast on the road and take evasive action like braking or switching lanes abruptly. This can be hazardous due to the random nature of the of the occurrences and them happening at times when a driver may be lulled into a false sense that the car seems to be driving itself well. So far we have been lucky that no other vehicles were traveling too close behind or to the side of us. We have experienced this behavior multiple times and there are other people online who have reported this. The car gave no warning indicators either before, during, or after the occurrence. Note that our car uses a Hardware 3 computer. I believe that this issue may have been fixed on newer Tesla cars that use Hardware 4.
