While driving with the Adaptive Cruise Control and the Road Departure Mitigation System engaged, then fails and disengages. The warning system indicates a problem that should be reported to the Dealer. This has happened on multiple occasions and was repaired by the dealer when the car had 254 miles by replacing the tailgate upper wiring harness and the Brake/Cruise Control switch. The part number replaced was 36750-TY0-J11 35350 SW. Since that repair, the problem has resurfaced at 4385 miles multiple times. After stopping and restarting the car multiple times, the systems apparently resets itself, but the problem reoccurs multiple times after that. I have no confidence that the system is consistently reliable. The problem initially occurred on Jan 17 2025 and again Sept 19, 2025
2025 Honda Ridgeline driver assistance complaints

Forward collision warning alarms when oncoming vehicle is recognized. This happens at least 3 times every time I drive. Only happens on 2 lane roads, not divided streets or highways. Very annoying and distracting.
As I was driving about 25 a 30 mph, I was in a right hand curve. When a vehicle in the opposite lane approached (still on their side of the road) my vehicle braked automatically for 1-2 seconds. This was unexpected and if there was another vehicle behind me then it is possible they may have rear ended my vehicle. The system has warned in similar instances to brake but did not actually apply the brakes automatically. This also happened when a vehicle in front of me was turning and as I had enough room to get by the vehicle again braked momentarily. This happened while going around 5 to 10 miles an hour and was unexpected and unneeded. I have not talked about this to the dealer but there are many complaints on Honda Ridgeline forums about this issue.
Collision mitigation brake system vibrates steering wheel,flashes brake, sounds alarm every time a car approaches in opposite lane on curves and often for no traffic at all. It gives so many false alarms I've had to turn it off for safety.
This is a brand new 2025 Ridgeline with only 900 miles. The Collision Mitigation Breaking System and the Lane Keeping Assist System does not work properly on my vehicle. The dealer where I bought the vehicle (Dick Brooks Honda in Greer) has insisted there's nothing wrong with the vehicle on two occasions. However, I took the vehicle to another dealer; the master technician said there might be something wrong with the radar system in my vehicle and to take it back to the original dealer. The original dealer won't even acknowledge what the other service department said about the radar system. Honda is just parroting what the original dealer is saying. I have a brand new vehicle that is not safe to drive and nobody is helping me. I have captured video on a GoPro of some incidents when this occurs. These systems go off for no apparent reason. When I manually turn off the CMBS, there's a persistent warning message that appears on the infotainment screen entitled, CMBS Problem. That message says: "The Collision Mitigation Braking System has a problem. Restart your vehicle. If the indicator remains on, have your vehicle checked by a dealer." The CMBS is malfunctioning, but how do I know if the system is off when I turn it off when this message appears? The dealer where I bought the vehicle from says "this is normal", but I know that is not true because I have looked at other 2025 Ridgelines and this message does not appear.
Unsafe auto high beams. They do not come on over 45mph. They have a mind of their own and seem to always come on and off at the wrong time. Also is dangerous to the oncoming vehicles that become impaired due to the high beams coming on when another vehicle is approaching. Especially most dangerous when you are on a 2 lane highway. Also the adaptive cruise control is inconsistent and seems to be very laggy and brakes way too hard.
The contact owns a 2025 Honda Ridgeline. The contact stated that the high beam lights turn on and off while driving 45 MPH or above at night. The contact stated that the headlights were flashing oncoming drivers. The contact had to deactivate the feature. Additionally, while driving on two occasions using the adaptive cruise control, the vehicle was braking hard. The contact was concerned about being rear-ended. There were no warning lights illuminated. The vehicle was taken to the local dealer, where it was diagnosed that the vertical mounting of the radar sensor was slightly off. The dealer leveled the system. The vehicle was repaired, but the failure recurred. The manufacturer was contacted and opened a case. The approximate failure mileage was 99.
I purchased a 2025 Honda Ridgeline and noticed that the turn signal is hardly audible. If you have the radio on or the windows rolled down, you will not hear the warning tone. In the infotainment system there is an adjustment that allows you to raise the volume of the warning indicator and even at the highest volume you can barely hear it. I also found that I am not alone and that this ia a common problem with some Honda models. Every other car I have ever owned made a mechanical or audio tone to warn that the signal light is active. This makes the driver behind you question whether you are taking a turn or not, should they pass you or not? I took it to the service department, and they could not tell me how to increase the volume. I had them go to another 2025 Honda Ridgeline and it had the same problem. I think that it is supposed to work with the infotainment system but even with their settings the issue persisted. Even the blind spot detection is inaudible. I think this is negligence on behalf of Honda. You can search on "Honda turn signal inaudible".
The auto dimming is way to sensitive. It turns down on road signs, street lights etc.
