2023 Honda Ridgeline electrical problems

Filed Oct 30, 2026 · Electrical, Transmission · CA

My 2023 Honda Ridgeline (about 28,400 miles) repeatedly loses power while driving. The instrument cluster lights up with every warning light at once, the truck stops accelerating, and I cannot maintain speed. It has happened on the freeway above about 60 mph, which is extremely dangerous with surrounding traffic moving at highway speed. Disconnecting the battery for about 15 minutes temporarily clears the warning lights and lets the truck move again, but the problem keeps returning. I have taken the vehicle to a Honda dealer three times for this same problem: July 2026, late August 2026, and October 2026. At the August visit, the dealer scanned the vehicle and found multiple lost-communication codes and DTC U0401 (invalid data received from PCM). The powertrain control module (PCM) was replaced under warranty and relearn procedures were performed. The problem returned after the replacement, and the truck is again at the dealer for diagnosis. I have video recordings of the failures and repair records for all three visits. I am concerned this is a defect in the powertrain control or vehicle communication system that can cause a sudden loss of power at highway speed, and that other owners may be affected. Please investigate.

This has happened for the last 2.5 years and has happened between 5 and 10 times. While stopped at a traffic light the Auto-Stop feature activates. When the light changes and I attempt to move, the vehicle enters "cuts off" and the dash board directs me to shift to Park or to step on the brake to restart the engine. It take multiple attempts but then it switches to Accessory Mode after which it generally starts. - Two pictures have been included. The one at night was in [XXX] and the other during the day, was taken on the corner of [XXX] and [XXX] in [XXX]. I also have a short video clip of the [XXX] incident which occurred about two days before the [XXX] incident. Once this begins I put on my hazards to direct other vehicles to drive around. I have reported it to the dealer. The dealer assured me it was the battery and they tested the battery but the battery was fine. The issue is similar to other 2023 and is covered by TSB 23-008/23-010 (Video Link: [XXX] ) INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Driving approximately 15mph on a gravel road in my subdivision I noticed smoke or steam coming from under the hood. The time was approximately 10: 30 am on June 4,2026 the 2023 Honda Ridgeline with 41,000 miles was immediately stopped and put in park. I exited the vehicle and started to open the hood and fire streamed out from the front of the vehicle. I backed up and went to the rear door and retrieved my dog from the back seat. The vehicle is a total loss as the fire spread incredibly fast. I’m lucky to be alive today. There were no warnings or messages.

The infotainment system failed intermittently two times prior, causing failure of the backup camera and cross traffic warning sensor system. The entire system failed a month ago and Honda has no idea when they can get parts.

The rearview camera continues to fail after recall for the issue was completed. Estimate 6 months+ since recall was performed to replace camera tailgate wire harness. It has begun random failures again. There is no indication from the dash of an error. When placed in reverse, the camera display in the dash goes nearly black or totally black; sometimes lane back lines are present, sometimes not. The current problem is entirely consistent with the failure conditions and symptoms prior to the recall update to replace the wire harness. The problem can fairly routinely be triggered by multiple uses of the dual-action tailgate movement. A few flat down and back up, then a few swing-gate actions will generally trigger the failure. When the camera monitor does have a normal picture, it will stay that way indefinitely -until you again have repeated tailgate movements using the dual-action feature. It is generally possible to perform several dual-action movements of the tailgate and restore the camera monitor to a functional view. The recall and replacement with an "improved" wire harness has failed to last; the identical problem is recurring. The vehicle was at a Honda dealer today. They report no error codes, they report no continuity issues with the wire harness. Proposed remedy is to replace the camera unit, despite no error codes. The only basis seems to be that they could not "see" a problem with the harness. Nor can they explain why the circumstances are identical to what caused the initial recall, but still feel it's not the cable. Nor can they explain why my repeated movements of the tailgate can make the display work again. This is a considerable safety issue as it's extremely difficult to back up the vehicle if you can't see behind/below the tailgate. Mirrors are not enough; safe backing requires the use of the rear view camera.

The automatic high beam system is terrible. It is too sensitive so the beams flash hi/low on and off. Even a small road reflector on a dark empty road will force it back to low beam. Other cars I own with this type system work much better. It’s a safety hazard because auto hi-beam is on by default and you can’t count on it providing the correct amount of lighting when on dark roads, plus it annoys oncoming drivers because of the constant flashing.

While driving a slow speeds will stall. It has a stalled in the middle of an intersection almost causing us to get T-boned. The last time this happen I was driving in a shopping center going around 5 mph and it has stalled. The truck is currently at the dealership for the second time for the issue. Also the transmission while driving at slow speeds shutters and vibrates. Also the lane keeping feature tries to pulled us off the road while driving at slower speeds.
