NHTSA Complaint #11463233 — 2021 SUBARU CROSSTREK

Subaru Pre-collision braking activates when no danger present. It detects exhaust steam or smoke as an obstacle. Approximately February 25th of 2021: While acceleration from a stop light in winter, Eyesight falsely detected the exhaust of the car in front of me as a danger and slammed on the brakes to a full stop causing the car behind me to bump into me. Thankfully this driver was paying attention and no damage was caused. This function overrode my foot being on the accelerator. Late Spring of 2021: While using cruise control on the highway, 70+mph, a diesel truck accelerated to merge. The eyesight again detected the exhaust as a hazard and slammed on the brakes causing the drivers behind me to take evasive actions and put them at risk for no reason. During both incidents, the collision warning lights fully activated. I spoke to the dealership about these incidents and was told to turn off the pre-collision system on cold days and watch out for diesel exhaust.
