2024 Subaru Outback: false forward collision warnings

Filed Sep 10, 2026 · Driver assistance · AL

I own a 2024 Subaru Outback Limited XT, VIN [XXX]. While traveling approximately 45–50 mph on a four-lane road with Adaptive Cruise Control (ACC) engaged, my vehicle suddenly and rapidly decelerated and automatically applied the brakes as I approached a police vehicle traveling in the lane immediately to my right. There was NOTHING in my lane for at least one mile ahead of me. The police vehicle was not in my lane. It was traveling in the adjacent lane to my right. As I approached the police vehicle, my Subaru unexpectedly began rapidly decelerating and automatically braking. I did not apply the brakes. There was no warning beep before the automatic braking occurred. The vehicle behaved as though it had detected an imminent collision or obstacle directly in its path, even though there was no vehicle, pedestrian, or other obstacle in my lane for at least a mile. The event occurred while Adaptive Cruise Control was engaged. I am concerned that the EyeSight/Adaptive Cruise Control and/or Pre-Collision Braking system incorrectly detected the police vehicle traveling in the adjacent lane as an obstacle or as being in my vehicle’s path. The sudden automatic braking at approximately 45–50 mph is a serious safety concern. A vehicle traveling behind me could have struck my vehicle because the deceleration was unexpected and there was no warning beep. This type of false or inappropriate automatic braking could cause a rear-end collision or other crash. I am requesting that the federal safety agency investigate whether 2024 Subaru Outback vehicles equipped with EyeSight and Adaptive Cruise Control are experiencing unintended or inappropriate automatic braking, phantom braking, or rapid deceleration when vehicles are traveling in an adjacent lane. I would like this complaint associated with other reports involving sudden braking, rapid deceleration, Adaptive Cruise Control, EyeSight, and Pre-Collision Braking in 2024 Subaru Outback vehicles. I am willing to provide additional informati INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION

On at approximately XXX 5:30am, while driving my 2024 Subaru Outback Premium Northbound on [XXX] right in front of the [XXX], the EyeSight Driver Assist / Pre-Collision Braking system engaged with hard/sudden braking despite no vehicle, pedestrian, or object present in or near the roadway. There was a vehicle following behind me, and the sudden braking created a near rear-end collision. Road conditions were dry, weather was dark but clear, and traffic was light to moderate. I am concerned this represents a false-positive activation of the automatic emergency braking system that poses a collision risk. I am requesting this be logged as a safety complaint against the vehicle's Collision Avoidance/EyeSight system.

The pre-collision braking system has engaged twice during normal traffic flows and came close to causing an accident.

The front collision warning does not work in this car. When coming within 5 feet of the car in front of my vehicle at higher rates of speed my car offered no warning indication nor did it brake. Pre collision braking is turned on. Lane departure all functions is turned on. Driver monitoring system is turned on. I took car in to have it evaluated and colonial Subaru in Feasterville told me all systems were fully functional.
