NHTSA Complaint #11534065 — 2023 TESLA MODEL Y

Approximately half a dozen times this year on highway journeys between California and Las Vegas, when the vehicle is on cruise control at approx. 70-75 mph, I have experienced brief instances of unnecessary, automated braking. Each time apparently in response to large black patches in front of the car, either a mismatched repair of the highway or a dark mirage type reflection of the sun on the highway. It appears to me that the vehicle cameras are occasionally mistaking these dark patches as an obstacle. Presumably lidar sensors would not react because the radar would not bounce back off anything, but I believe my car does not have lidar sensors. In each case there was an approximate 10 to 15 mph reduction in speed and then the vehicle quickly recovered. Fortunately, no other vehicle was tailgating me at the time but if one had been, I believe there is a realistic risk of being rear ended. Alternatively, the driver behind would, presumably, apply the brakes, which may cause a chain reaction when the highway is in fact, clear ahead. I have not contacted Tesla. Based on other reports online, it appears to be a waste of time.
