2025 Honda Civic Driver Assist & ADAS Problems

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.

I am filing a formal safety-related complaint regarding my 2025 Honda Civic Sport Touring Hybrid and the performance of its driver assistance systems. This vehicle uses a camera-only driver assist and lane keeping system. I previously owned a 2018 Honda Civic Touring that used both radar and camera. The earlier radar+camera system performed significantly better, maintained the lane more accurately, and provided smoother, more predictable behavior. The 2025 camera-only system frequently: – drifts within the lane – loses lane tracking unexpectedly – requires frequent driver intervention – feels less stable at highway speeds In my opinion, the newer vehicle’s system represents a downgrade in functional safety compared with prior-generation Honda systems. This change was not disclosed during the sales process, and many owners may assume newer models offer equal or better driver-assist performance. My concern is that removal of radar and reliance on camera-only sensing has resulted in degraded lane keeping performance that could increase crash risk due to unexpected disengagement or poor lane centering. I request this information be reviewed as part of consumer safety monitoring of driver assistance systems.

While driving on Rt.119 through Uniontown PA, I was going 60-65 mph on a four lane road passing a cat on the right. I was about 3/4 of the way passing the car when three emergency braking kicked in and applied full braking. The road was straight, there was no vehicle or other obstruction in the road. This happened at approximately 3:30 P.M on 11/14/2025 with overcast sky and dry conditions. This caused the full sized tractor trailer behind me to lock up his brakes to attempt to not hit me. The only thing I can think of that kept me from getting hit, was I was able to hit the gas pedal.

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.

The contact owns a 2025 Honda Civic. The contact stated while driving approximately 64 MPH, the Forward Collision Avoidance system unintendedly activated without a person or a vehicle nearby. No warning lights were illuminated. The failure reoccurred on several occasions. The vehicle was taken to a dealer to be diagnosed; however, the cause of the failure was undetermined. The vehicle was not repaired. The vehicle was taken back to the dealer to be diagnosed; however, the cause of the failure was not yet determined. The vehicle was not repaired. The contact researched and was made aware of a Class Action Lawsuit associated with the failure. The manufacturer was notified of the failure. The failure mileage was approximately 6,555.

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.
