NHTSA Complaint #11417856 — 2020 SUBARU FORESTER

Subaru eyesight technology has a pre collision feature along with lane departure feature. Latter can be turned off permanently, the pre-collision feature cannot. Number of instances where this has malfunctioned in a way that is unsafe. Driving in upstate NY on foggy morning, winding hilly roads, 50mph roads. Road had a driveway with a parked car not moving, parked and the pre collision system tried to break, so slowed down the car but there was another coming behind from a hilly turn, not aware I would suddenly slow, especially as I did not anticipate the car would try to put on breaks on its own for a parked unmoving car. No collision resulted fortunately, but unsafe if the car behind had not been able to slow to accomodate for the faulty detection by subaru’s eyesight, thinking the parked unmoving car was a sudden stopping vehicle in front of me, when the winding road was actually clear for me to continue driving. Another incident on another road where a series of 4-5 cars driving constant speed, fixed distance from each other, then first car signalled to turn right and stopped; cars behind just went around them slightly as they were waiting to turn, and I was going to follow suit, the train of cars in front of me, when suddenly eyesight pre collision detected that turning vehicle as something to try to brake for, and the car behind me did not expect the sudden breaking attempt to slow down, and again, close call, no collision resulted but unsafe when the human driver was expecting to continue along with the other train of cars and not expecting a sudden stop. I have called subaru both dealership and main office but informed there is no way to permanently disable the pre collision setting in the car. Concerned that if this feature is on, and erroneously detects an object in front, such as that parked unmoving car, in other situations the cars behind me may not be able to accomodate the attempts at sudden breaking by the subaru eyesight technology. Dangerous.
