On XXX, while driving my HondaTrue Certified 2025 Honda Ridgeline RTL AWD, I stopped at a traffic light and the Auto Idle Stop system automatically shut off the engine. When the traffic light turned green and I released the brake pedal, the vehicle attempted to restart but failed. The starter sounded weak, as though the battery did not have sufficient power to crank the engine properly. The transmission automatically shifted into Neutral, and a battery warning light illuminated on the dashboard. I was unable to accelerate or move the vehicle under its own power. I had to shift the transmission into Park, press the ignition button to shut off the vehicle, and then manually restart the engine. The engine restarted normally, and the battery warning disappeared. I contacted an authorized Honda dealership, Lia Honda of [XXX], on XXX. After checking my vehicle's VIN, the service advisor informed me that a Honda service bulletin issued XXX, applies to my vehicle. According to the advisor, Honda currently recommends disabling Auto Idle Stop until a permanent repair is available. This malfunction occurred in active traffic and created a safety concern because the vehicle unexpectedly became immobilized at an intersection.

No Restart After Auto Start/Stop Engages
On June 3, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE22005 after the agency received VOQs and several field reports concerning the Auto Idle Stop (AIS) feature on 2016-2019MY Honda Pilot vehicles. The complaints allege that the engine fails to restart on its own from a complete stop at a traffic light or road intersection with the AIS function engaged. The subject vehicles are equipped with a 3.5L engine with a 9-speed automatic transmission. On January 6, 2023, Honda released service bulletins 23-008 and 23-009. These service bulletins address the failure to restart issue in the 2016-2019MY Honda Pilot vehicles, as well as the 2015-2020 Acura TLX, 2016-2020 Acura MDX, 2019-2022 Honda Passport, and 2020-2023 Honda Ridgeline vehicles. The repair outlined in the service bulletins is a two-stage countermeasure to remedy the issue. The first stage is a Programmed Fuel Injection (“PGM-FI”) software update. The second stage is only deployed if the software update fails to remedy the issue. The second stage, depending on the model and model year, consists of replacement of the starter assembly, starter relays, and a valve adjustment. Additionally, Honda extended the warranty coverage to 10 years with unlimited mileage for vehicles requiring the second stage component replacement. ODI continues to receive complaints of the AIS failure to restart, with many complainants alleging the campaign countermeasures had been completed.the federal safety agency has reviewed Honda's Information Request Letter responses involving warranty claims, lawsuits, and consumer complaints in addition to ODI's own data. This Engineering Analysis is being opened to further consider the potential safety defect, including gathering additional data regarding Honda’s service campaign efficacy. ODI is additionally expanding the scope to encompass all vehicles addressed in Honda’s service bulletins 23-008 and 23-009 as well as newer model year vehicles, which are substantially similar to the vehicles covered by the service campaign.

What 2025 Honda Ridgeline owners say
Most recent owner complaints, unedited.
Since the beginning of ownership of my 2025 Honda Ridgeline Sport, the Auto Idle Stop system has malfunctioned. The dashboard remains illuminated and displays an error message related to the system. I am concerned about the reliability of the system and the possibility that the engine may not restart as expected. This issue has existed since I first got the vehicle. I am reporting it so that the federal safety agency can review the problem and determine whether it presents a safety concern.
When sitting at a traffic light, the auto start/stop feature engaged and shut down the engine, when my foot was removed from the brake, the truck did not restart. I had to put the truck in park and manually press the start button. This caused a safety issue by making the vehicle inoperable in the middle of an intersection. The vehicle has not been inspected yet, but will in three days when i take it to the dealer.
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. They acknowledged it was a problem but that no recall has been mandated thus far and there is nothing they could do. They only suggested to call corporate Honda.
I bought the vehicle with around 13k miles in May of 2026. Since I have had the vehicle, I have had 4 incidents with the vehicle auto idle-stop (auto engine start/stop). I have experienced the vehicle completely die when trying to start back up during idle stop. Of the four times - one was on a major 3 lane highway in stop and go traffic. Another time, I was stuck in the middle of an intersection waiting to make a turn. It usually does not restart and battery lights come on the dashboard. After several attempts, or sometimes 30 seconds to 1 minute it does restart. I usually shut off the idle start/stop but sometimes I forget. After researching this issue, it seems to be a common problem. It is a severe issue and needs to be addressed. I use the truck as a second vehicle, but I am scared to let my son or wife use the vehicle. Honda needs to address the issue immediately before someone gets hurt or killed.
The vehicle was stopped at a light and just died. We are 99% sure the start/stop button was turned off but Honda insisted it must have been active because they have had to replace many starters due to the starter not starting after the vehicle has stopped at a light. We were not told this could happen. They said they do not know how long it would take for the part to come in and just press the start/stop button everytime after starting the car and it would be fine. We had been doing that for the last month so the air would stay cooling so we were not comfortable driving it. They would not offer a vehicle either. This appears to be a major concern. We filed with Honda Corp as well.
starter went bad due to the auto idle start/stop the vehicle shut off at an intersection and would not start back they replaced the battery and said it was bad 3000 miles later the starter is bad according to the Fred Anderson honda dealership as i was having the same issue
This afternoon, the Auto Engine Stop System Problem light came on, the truck hard-stalled at a very busy intersection, and it forced a manual reboot from Park to get moving again.
When I stop and try to go car turns off and dosnt start
On two occasions, immediately after re-fueling the vehicle, the engine auto idle stop failed to restart the vehicle. Both times this happened at busy intersections. A series of messages appeared on the display. I was flustered because cars behind me were honking as I was blocking traffic so I don’t exactly remember the error messages. One message said to put the transmission in park. Another said to hold the brake and the engine start button. Eventually the engine did re-start by holding the start button down.
