Engine idle stop function failed to restart automatically while I was stopped at a stop light. I was at a complete stop at a four way intersection with vehicles behind me and my vehicle did not restart after light turned green and I released brake and stepped on accelerator. Error message flashed stating to press brake and push start button. Vehicles behine me honked for me to proceed but I could not move. I turned on my hazards and attempted to restart engine. I stepped on brake and pushed start button. Vehicle did not start, I repeated stepping on brake and start button again and did not start. I did it a third time and vehcile started. A police car behind me pulled up and asked if I was ok just as I started my vehicle and pulled away. This is the second time this has happended but I did not report it and thought it was me not stepping on the brake hard enough. The first time was about six months ago in a similiar situation at a four way traffic light.

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 will be taking the vehicle back to Honda to address this auto start failure, but I am aware that there is currently not a recall for this auto idle stop/start feature, despite it being well documented by other Honda vehicle owners.

I am reporting a recurring auto idle stop no-restart and starting-system failure in a 2024 Honda Ridgeline. At approximately 35,072 miles, while stopped at a traffic light with auto idle stop engaged, the engine shut off but failed to restart when the brake pedal was released. The vehicle remained disabled in the intersection until it was manually restarted, creating a risk of a collision. An authorized Honda dealer found both positive and negative battery terminals loose, tightened them, reported that the battery passed a load test, found no diagnostic trouble codes, and returned the vehicle. The battery had already been replaced at approximately 30,238 miles after a slow-start complaint and a failed battery test. The condition recurred at approximately 42,563 miles. After the engine shut off at a light, the vehicle displayed an orange “p” and “system problem detected - shift to park,” went into neutral, and required a manual restart before drive could be restored. The dealer later reported that the replacement battery tested at approximately 197 cca against its 650 cca rating, but no root cause for the rapid deterioration or the shutdown/no-restart condition has been identified. The vehicle now intermittently cranks slowly and appears strained while starting. No permanent repair has been completed. The vehicle is available for inspection. The condition creates a safety risk because the vehicle can fail to restart or move from an intersection and may enter neutral unexpectedly.

My wife and I had decided to empty our storage unit, so on memorial day we began moving everything into the garage. After five or six trips Honda, I pulled the car up beside the RV and close to the house for what turned out to be the last load. I unloaded my bicycle and nearly everything else, leaving only a few small items, and then removed the massage table from the back seat. The engine was off this entire time. That was when I noticed smoke coming from the engine compartment. At first, I thought the radiator had overheated, so I tried to open the hood, but it was too hot. I went into the garage for gloves and a fire extinguisher and tried again, but still could not get it open. Realizing the situation was getting worse and that I could not stop it there, I jumped into the car and tried to start it. To my surprise, it started immediately, and I drove it as fast as I could out to the street in front of the house. Only later did I realize that this likely saved my RV—and possibly the front of my house as well—from catching fire. We were so blessed that I was able to move the car to a safer location and no one was hurt. It was a miracle.
