2025 Honda Ridgeline Electrical Problems

Owner reports

Selected complaints filed with NHTSA by 2025 Honda Ridgeline owners, lightly cleaned up (personal details are redacted by NHTSA).

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. …

What component or system failed or malfunctioned, and is it available for inspection upon request?: The auto start stop feature failed, resulting in the vehicle lurching then dieing without any prior indication. How was your safety or the safety of others put at risk?: The vehicle's lurch and sudden loss of power occurred at a red light when turning left. If I were the first car in line, it would have left me in the intersection with a 65 mph speed limit, creating the potential for a significant accident. Has the problem been reproduced or confirmed by a dealer or independent service center?: No it has not, but was taken to a dealer in the last two weeks for this problem, in which all systems were operating as intended. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others?: Yes it has where the problem could not be identified. …

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. …

This vehicle has auto stop for fuel economy. It can only be turned off each and every time you start the car. I often turn it off but do forget to do so sometimes until it occurs on my trip. The problem is that approximately 7 to 10 times, when the feature is left on and the truck shuts itself off at a stop light, when attempting to go, the truck does not restart, a warning light comes on and instructs you to put it in park. You must put it in park, then shut off the truck, then restart in order to proceed. This is extremely dangerous and very unnerving when it occurs. I travel daily on a 55 mpg road with multiple lights. The problem could easily result in being rear ended as you try to go through the procedure to get going again once the light turns green. At the very least, I get angry beeps trying to get me to move which only heightens the anxiety. I contacted the Honda dealership. …

On several occasions, while driving at night, the Auto dimming headlights would not dim. Last evening, on 2 different occasions , on a rural road, no road signs, mailboxs . nothing that would cause a issues, the headlights would not go from high beam to regular (or Low beam.) 2 different times , vehicles coming at us, the lights would not dim. Time was apx 9pm , not a cloud in the sky. I had all so noticed while driving on a interstate , the same thing would happen, the lights would not dim,, drive maybe 50' or 5-10 seconds later. they would dim. There seems to be no rime or reason of if or when they will dim. We had 18 and 22 Outback and they worked perfectly , where the Ridgeline has malfunctions. Asking the dealer they have not heard of anything wrong .. I have not had them to check , but have heard from other owners of the Ridgeline and they are complaining about the same thing. …

The Auto Idle Stop/Start feature has malfunctioned multiple times, leaving me stalled out at a green light in traffic. Sometimes the system hesitates to restart and shows a warning message on the dash that is too long to read for the split second that it shows, and other times it requires a full manual restart of the vehicle. The feature works to shut the engine off, but intermittently does not start back up when taking foot off the brake, and requires a few shut off instructions that are complicated to follow when sitting in a parked vehicle in moving traffic. This is highly unsafe. The hesitation warnings were visible on my maintenance report, but nothing was said about them at the service center, so I did not think they were an issue. …

I bought a new 2025 Honda Ridgeline truck from Hendrick Honda, Easley, SC and within the first 24 hours the instrument display showed an "auto idle stop error" and to get service at the dealer. I took it back to the dealer within two days, and they said they ran diagnostics and couldn't find nothing wrong. The service advisor said "it will probably just go away as you drive it more." Well, after a couple thousand miles now, it has not gone away but sporadically reappears while driving. I called the service advisor back and he said I could bring the truck back and they could try a diagnostic test again. I asked him to instead contact Honda automotive as this is a known issue with the Ridgeline then call me back to notify me of the solution. He never called back.

When stopping with the auto idle stop system engaged, the vehicle failed to auto restart after letting off the brake pedal. This has happened three times with the last two occurrence less than a week apart. The first two times I was in a queue at a stop light and was able to shift into park and manually restart the car and proceed on the road without further incident. The third time in particular I observed that the manual start did not work on the first attempt but did on the second attempt. There were no warning indicators or messages prior to the auto restart failure. There is some risk of safety when a vehicle remains unexpectedly stopped in the road while surrounding traffic is moving. I plan to take the vehicle to the dealer for evaluation.

since I purchased this truck brand new from the dealer, the brakes always had air in the lines. No matter how many times I bleed the brakes, there is still air in the line. From my understanding, previous years of this truck had master cylinder issues. I went to the dealer and they refused to fix the issue, because I already attempted to fix the problem. Also, the car doesn't start when shut off during hot weather and you want to start the car again. You have to wait and try again. The car is laboring to start again. This vehicle is also known for slow starts.I hope you take this matter seriously. This is the issue with every brand new ridgline. Take your pick. I paid over 50k for a new truck and have to deal with these issues.

When stopped in heavy traffic, the auto idle engaged. I got a "System problem detected. Shift to Park." warning. When I shifted to park the vehicle experienced a total electrical blackout, including a loss of hazard lights. It took several minutes for the modules to reboot. This happened 3 times in 20 minutes as I attempted to find a safe place to pull over. My life was put in danger because it was dark, raining heavily, and my hazard lights were inoperative. It happened a few hours after I bought the car at the dealership. I am waiting for a tow truck now. It is available for inspection.
