2023 Honda Civic: adaptive cruise control problems

Filed Sep 15, 2026 · Brakes, Driver assistance · KS

I have a christmas tree of lights on my dashboard, I cant use my cruise control or lane assist features. I took my car to a Honda dealership to have a diagnostic done and found that the EPB on the left rear brake was bad. I changed it out and had the computer reset to find that the car is still having issues and now I'm being told to change out the ABS wheel speed sensor that connects to the EPB. When looking online this is a commonly known issue with the 2022 and 2023 Civic sport touring and Honda is aware of this and are trying to get out of having to fix it. This is a huge concern for me because I'm currently living in [XXX] right now for work and have to park on an incline and have been told that at any point the parking brake can give out and my car can take off. This is a huge safety issue that could severely hurt someone, Honda needs to take responsibility for their poor build and fix it before someone gets seriously injured. For some of us not parking on a hill isn't an option. Please please please help us get this issue resolved and make them take responsibility of their poor design. Thank You!

Clutch began to slip at 20,000 miles. This caused unrepairable damage to the flywheel. This put my safety at risk as clutches wearing out could cause the car to slip out of gear and/or damage the maneuverability of the vehicle. This problem was fixed by the dealer, but they blamed me for the damage and claimed clutch is a wear component. I was charged $3,000 for the clutch and an additional $2,000 for the flywheel. I have seen many reports online of people with the same car (2023 Civic Sport Touring Manual) with the same issues. All people have been ignored by Honda corporate, citing user error. This has not been inspected by the manufacturerer as I am aware No messages of the problem, other than the cruise control stopping under load.

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 the federal safety agency can document and evaluate whether this represents a broader safety defect.

I get a random warning that is an issue with the braking system and the Brake light comes on. The lane departure and cruise control is shut off while the vehicle is in motion. There is a sudden and unexpected drop in speed when the cruise control is shut off by the vehicle. The vehicle remains operable without the systems activated the warnings go away after restarting.

Under multiple conditions, both intercity highways and two-lane country highways the cars adaptive cruise control with randomly slowdown/brakes extremely hard. In one specific instance I was driving home in the middle of the night with a vehicle behind me and with no other oncoming traffic or cars in passing lanes and the adaptive cruise "brake checked" the car behind me, I was able to react and cancel the adaptive cruise and avoid an accident. When adaptive cruise is set it will also aggressively approach the car in front, instead of gradually slowing down it will continue at the set speed until the car realizes it's to close and will slam on the brakes to slow down. When adaptive cruise is turned off the car will slam on the brakes if you attempt to accelerate to pass someone and coast back to set speed. in other words, the car will slam on the brakes to resume the set cruise speed. Fortunately, no cars have been behind me when this has happened. Nowhere does it say that this will happen when using normal cruise control? Speeds and conditions varied from city traffic going 20 - 40 mph, the highway going 55-65 and the interstate going 70-80 mph. some instances were at night others were during the day.
