Automatic Emergency Braking problems of the 2023 Honda Civic

Phantom braking when there is no cars or anything on the road. The car would immediately brake out no where. It could cause an accident randomly braking when using cruise control.

I am reporting repeated electronic safety system malfunctions in my 2023 Honda Civic sport sedan that occurred while driving at highway speeds and present a serious safety concern. In June 2025, while driving at highway speed, multiple warning lights and messages suddenly appeared, including: brake system warning, road departure mitigation system warning, parking brake/brake hold warning, and adaptive cruise control warning. These warnings appeared simultaneously without prior notice, raising concern about whether the braking and safety systems were functioning properly while the vehicle was in motion. I took the vehicle to a Honda dealership for diagnosis. The dealer did not identify a specific electronic or mechanical defect and instead claimed the issue was caused by liquid spilled near the electronic parking brake switch. I was told the repair was not covered under warranty and paid approximately $600 out of pocket. No evidence was provided explaining how this would cause failures across multiple safety systems. In January 2026, the same group of warning lights appeared again under similar conditions while driving at highway speed. This recurrence strongly suggests the issue was not caused by driver error but may be related to an intermittent electronic, sensor, or control system defect. I have a scheduled dealer appointment tomorrow to address this second occurrence of electronic malfunctioning. Because these warnings involve critical braking and collision mitigation systems and occurred while the vehicle was in motion, they present a potential safety risk. I am submitting this complaint so NHTSA can document and evaluate whether this represents a broader safety defect.

I rear ended a vehicle and my brakes did not respond nor the emergency system activate I gave a dash cam on the incident and no one has inspected the car for that failure.

The brakes slam on there own causing all safety features to go out and the car to go out of control. This is the 3rd time this has happened in 3 months. The dealership is telling me they won’t look at it for 3 months I could be killed in that time my car is dangerous.

Brake mitigation system will automatically slam on brakes and show brake light with no objects in the way.

5-24-2023 I was driving my vehicle on a clear unobstructed roadway when out of no where the collision brake mitigation system flashed on the dash and warned me to see dealer after this occurred I lost pressure and power to my brakes. After exiting my car I saw the front rotors where colored red and the right front passenger brakes where smoking.
