NHTSA Complaint #11634566 — 2022 SUBARU WRX

During driving, especially when it is cold outside, the Subaru Eyesight Pre-Collision system (automatic emergency braking) can be triggered by exhaust smoke from a vehicle in front of it. The braking system can be falsely activated, which could cause your vehicle to be hit from behind. There is no way to adjust the sensitivity of this system. It is only meant to be activated by objects, but since the system is camera-based it might think that a large cloud of exhaust is actually solid. In the specific instance when this happened, I was waiting at a red light behind a GMC Acadia. When the light turned green, a lot of exhaust came from that car, and the pre-collision braking was activated, causing the car to activate the brakes very abruptly. At the next light, the same thing happened, but the car didn't hit the brakes that time since I lifted off the accelerator, but the warning buzzer still activated. Video showing the problem: [XXX] The loud grinding noise after the pre-collision warning beeps is the sound of the brakes when they are applied by pre-collision.
