The contact owns a 2023 Subaru Legacy. The contact stated that while driving at various speeds, the forward collision avoidance warning system would independently be active without an obstacle in front of the vehicle; the "Obstacle Detected" warning message would appear on the instrument panel. The contact also stated that the forward collision avoidance feature had failed to operate on two separate occasions in which the contact struck a deer. In both instances, the contact struck a deer while driving at about 30 MPH. No alerts, warning messages, or safety features were activated during either accident. The air bags did not deploy in either accident. A police report was not filed and no injuries occurred during either accident. The vehicle was taken to two separate dealers-Jenkins Subaru(750 Lodgeville Rd, Bridgeport, WV 26330) and Subaru of Morgantown(1730 Mileground Rd, Morgantown, WV 26505), but neither were able to duplicate the failure. The manufacturer was also notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 50.
