2025 Honda Civic: adaptive cruise control problems

Filed Sep 28, 2026 · Acceleration, Brakes · AZ

I was driving with the cruise set at 74mph as a lead car on a highway, overcast day. No vehicles, animals, trees or plastic bags had flown in front of me when the car slammed on the brakes causing the car following me to also slam and switch lanes to avoid rear ending me! Today is the third time I have taken this car back to dealership to look into. The previous two times they told me to shut off the adaptive cruise control which is not a fix! That is a feature I use because most of my driving is highway. Dealership of purchase is also dealership that I have taken care to previously. This event today actually scared me, thank goodness the driver behind me was paying attention.

This vehicle suffers from phantom braking. With the adaptive cruise control set, at times, in the display of the instrument cluster, the display shows a semi, motorcycle or car that is not there in real life. When this happens the car applies the brakes and starts slowing down. Sometimes this is bad enough that the collision warning message comes on and the brake application is very aggressive. The type of weather or road surface does not seem to matter. It seems to be very random. This happens once a week. Not just on the date provided below.

“Collision mitigation system problem see dealer” warning! Once at unknown mileage around 6,000 and once at around 10,000 miles. Random vehicle braking around 6-8 times in 12,000 miles with no reason. Braking happens while in cruise control. Both times that the warning messages appeared it was along with warnings for adaptive cruise control, automatic braking, lane departure, lane keep assisting. Many warnings all flashed consecutively with the final warning about collision mitigation system problem see dealer.

On November 5, 2025 a few dash errors came on, they were: 1. Brake hold system problem 2. Vehicle stability assist problem 3. Emission system problem 4. Road departure mitigation system problem 5. Collision mitigation system problem 6. Lane keeping assist system problem 7. Adaptive cruise system problem 8. Hill start assist system problem 9. Tire pressure monitor system problem I called the dealership on 11/5/25 and made a service appointment for 11/6/25. The dealership looked over the car and stated that the code the car was throwing was "Low Fuel Pressure". The dealership stated that they do not know why the code was present as the car showed signs of issues, they cleared the code and released the car back to me on 11/6/25. On 11/24/25 while driving on a major highway the car stalled about 8-10 times. I contacted the dealership and went right into the dealer on 11/24/25. The dealership kept my car and issued a loaner vehicle to me. On 11/25/25 I received a call from the dealership stating that the high pressure fuel pump would need to be replaced. The fuel pump was replaced on 11/26/25 and the service manager called me stating that they would keep the car to test drive and monitor it for further issues. On 11/28/25 I received a call from the service advisor stating that upon further checking the car they have located a transmission leak and found large chunks of metal in the transmission. The service advisor stated they would reach out to Honda and get the recommendations on fixing the problem. On 12/1/25 the service advisor reached out to me and stated that Honda recommended they clean the leak and release the car back to me. The service advisor stated that they were not happy with this outcome and then reached out to their district representative, the district representative recommended that they clean the leak, test drive the car for about 20-30 miles and send photos of the chunks of metal in the transmission. I am now waiting to hear back.

While driving at highway speeds with the Adaptive Cruise Control system active, the system is causing the vehicle to come to a complete stop to avoid a collision that does not exsist. In all cases when this has occurred, there are no other vehicles on the road. This inlcudes in front, beside or coming toward me from the opposite direction. When this does occur, the screen does show a vehicle icon as if it is detecting a vehicle in front of me but there is none. Since purchasing this vehicle in May 2025, this issue has occurred 6 times. I have brought this to my dealers attention during my most recent visit and was advised Honda was working on an update to resolve this issue but I have not received any communication from Honda indicating a recall was coming or an update to resolve.

While utilizing adaptive cruise control in clear weather, the system will harshly brake when there are no obstacles or vehicles ahead. I have almost been rear ended on numerous occasions due to unexpected braking while at highway speeds. I have not gone to the dealership yet, but intend to do so. During these braking events there are no other warning lights, and no other visual or audio alerts.

When traveling with cruise control enable the vehicle random slams on the brakes by itself even when their is no vehicle present in front. This has happened mutiple times on the highway and interstate. It has almost gotten me rearened from a vehicle deiving behind me. This is extremely dangerous. I made the dealership aware of the issue and they refused to address it.
