NHTSA Complaint #11450019 — 2021 TESLA MODEL Y

The vehicle driver assist system frequently has phantom braking in situations it should not be, especially when there are vehicles behind putting us at risk for a collision due to unexpected braking behavior of the car. This happens especially in setting of 2 lane roads with oncoming traffic, and guaranteed with a truck in the vicinity. On major highways it is less so, but does still happen occasionally. On local roads even if straight and no obstruction the automatic braking without notice occurs when least expecting. Also the lane departure system disables automatically for the remainder of a drive if you veer off a lane even once and didn't take the corrective action the vehicle thinks should have happened. That's not how a safety feature should work... It should remain on regardless. As much as I do enjoy this car, these quality issues definitely make you second guess and keep a closer eye on how you drive to avoid accidents if the system decides to not work as advertised
