We've been experiencing issues with the Auto Idle Stop feature (the auto restart in particular). On multiple occasions, the vehicle will automatically turn off the engine while stopped in traffic, but will fail to start back up, requiring the driverto manually turn the vehicle off and back on via push button starter (sometimes multiple restarts is necessary to get it moving again). This seems VERY similar to the investigation referenced under - EA25004.

The idle stop system frequently fails to restart the car after shutting down the engine at a stop light. In some cases the car is difficult to restart using the starter button. In other instances the car restarts and then dangerously lurches forward.

The vehicle's Auto Idle Stop system shuts off the engine at stop lights and other low-speed stops and, on multiple occasions, fails to restart, and the AIS disable button is sticking. We disable AIS every single time we drive the vehicle, and on multiple occasions the button has re-engaged itself mid-drive, meaning the safety hazard cannot reliably be avoided even with the workaround Honda recommends.

The vehicle's auto idle stop system is malfunctioning, resulting in the engine failing to restart from a complete stop. This total failure has occurred on five separate occasions, including while stopped in active traffic intersections. Prior to these total restart failures, the vehicle showed the following symptoms: 1) Initially, the vehicle experienced rough engine idling, abnormal vibrations, and a raw gasoline odor after driving. 2) This progressed to a noticeable delay between releasing the brake pedal and the engine attempting to ignite, during which the starter sometimes sounded strained. 3) This has culminated in the current defect where the engine shuts off normally when stopped at an intersection, but completely fails to immediately restart when the brake is released. This defect completely immobilizes the vehicle in active traffic lanes, exposing us to an immediate and severe risk of a rear-end collision. When the engine fails to restart, the vehicle locks the transmission out of drive and triggers a warning on the dashboard. It is a highly hazardous situation, especially with a lot of distracted drivers on the roadways.

I've had several incidents of my car stalling occur since the purchase of the vehicle over the span of 16 months, probably around a dozen times or so. I will stop at a stop light and the vehicle's idle-stop system does not function properly. The vehicle shuts off but does not auto-restart. When I try to manually restart, nothing happens. There have been times where it took several times before the vehicle started back up. Even more seriously, I've stopped in the middle of traffic and the same thing happened. We have had a couple of very scary incidents of cars having to move over a lane to pass our idle vehicle. Thankfully no car hit us due to our idled vehicle. We have owned this vehicle for less than 1.5 years and have had two battery replacements. I've also had the vehicle not start from my garage or parking lot. When I try to start the vehicle a second time, there are times where the start button feels very firm and doesn't push down easily. I have to push the start button several times before the vehicle starts. I'm grateful there have not been any major accidents occur but this is an extremely unsafe situation for the driver and their passengers.

This is the second time I have taken it to the dealership. When sitting at a stop and the automatic stop and start happens, it acts like it does not want to crank back up. Last time the dealership said it was the battery; they replaced the battery, but that has not fixed the issue. if I am at a stoplight and it does not start back, that is not a good feeling my wife now does not want to drive the van anymore because of the seriousness of this issue as well has having young children in the car. This is a van that was bought brand new and has been in the shop more than it has been driven.

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.NHTSA 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.
