The auto start/stop on my vehicle doesn't always work. I come to a complete stop, the vehicle turns off and when I pick my foot up off the brake to restart the car sometimes it will stall. There is no warning message or indication whether or not the car is about to stall, it just happens randomly. We cannot consistently replicate the issue. In order to restart the car I have to hit the start button, wait for the car to completely shut off and then turn the car back on creating a huge safety issue especially if I'm in the middle of an intersection waiting to make a left-hand turn. This is an accident waiting to happen. I brought my car to a Honda dealership approximately 6 months ago and brought the issue up to them. They told me they could find no issue with the car, couldn't replicate it and told me they had never heard of it before. It wasn't until I did an online search a few days ago that I realized that I wasn't the only one having this issue. I drive my children in this car and would be willing to allow anyone to inspect my vehicle to try to get to the root of the issue. This is a huge safety issue for what is supposed to be a safe family vehicle.

we bought April 2021 and 1st issue not even 60 days after purchase, dealer removed warranty without us knowing! We have had problems ever since with warming lights coming on & flashing on multiple occasions, even while traveling @ 50 mph!. Huge safety issue as the vehicle jolts and then looses power and can't pick up speed and go with flow of traffic! Someone will get in an accident because of it and that will be a HUGE liability for honda as you all are ware of these issues and are doing NOTHING to recall them and fix the problem! This is a problem for many honda pilot owners from all the honda forums i have read and research ive been doing! i want the issue resolved as this is NOT a random. I just read that there was a service bulletin in 8/2019 pertaining to this specific car/VIN and it references faulty fuel injectors. i have no way to know if this was completed. i feel i should be able to have the injectors serviced/replaced at NO COST to me as this is a HUGE problem with 2016-2017 pilots and the fact a honda dealer pretty much sold us a LEMON of a car! I want our pilot fixed as it is a problem that Honda has been having with 2016-2017 pilots and Honda should be liable for this! Happened again today and has been happening more frequent in the past few months but have been dealing with it since we bought the vehicle. recent mechanic said the ECM/PCM may be faulty as you cant get a viable code as everytime it happens it throws all kinds of warning lights & codes that are not accurate.

I have a 2017 Honda Pilot Elite. My car has had issues since I purchased with the stop/start feature and it’s progressively gotten worse. It’s currently failing every day. In 2017, it was the automatic stop not working right. It would intermittently come on/off when at a complete stop. It never quite functioned properly. It’s so bad, that I turn feature off when I start the car. Unfortunately, I can’t have it default to off so if I don’t remember to turn off auto-start every single time, then I have issues. My son was 3 years old when I bought my car. I would be at stops and the car would shut off. Then, it wouldn’t start. It would require me to press brake+gas+start button to reset car. I have come very close to getting into accidents while at stops and have had drivers with road rage come after me since I made them miss the light while my car restarts. I have been in the turn lane with heavy traffic and my car stops in the middle of the intersection. In 2018-2020, it progressively gotten worse. I took to Southeastern Honda to get looked at and was told that’s just how it works. After 2020, the car stops and will not restart at all. It would intermittently happen where I would need to get a jump start to get car running. I took to Space Coast Honda thinking it was my battery or starter. I was told that it tested fine, but still does it. In 2022, my car progressively got worse and requires a jump start. I since purchased a jump starter that is portable. I have to use it every single day. I have narrowed down the symptoms. If I drive 30 minutes and turn car off and immediately back on.. it will not turn over. I have to wait 4 hours and it works. I have measured my stop battery at 11.7 when it doesn’t work. If I wait 4 hours or jump start.. then it requires a 12.6 to start. I researched and found article that is exactly what happens https://www.cnet.com/roadshow/news/2016-2020-honda-pilot-nhtsa-investigation-engine-failures/#ftag=COS-05-10aaa0j

When my auto stop idle engine kicks on, and stalls when I try to depress brake and press gas. It has happened approximately 10 times over the past year and a half, always in an intersection when it’s dangerous. I have taken to the dealership more than once and they have been unable to resolve and recommended I replace my battery which I did which has not made the situation better. I also just filed a complaint with Honda but this is very dangerous and needs attention.

On multiple occasions, while the auto idle was one, I stop at a red light or intersection and when I lift my foot off the brake the vehicle shuts completely off. One time, I called 911 for police officer assistance to alert that I was stranded in the middle of the highway. I was so afraid I was going to be rear ended by fast moving traffic. Just yesterday, while stopped at a red light, a fire engine stopped and 4 fire fighters got out to offer assistance while I sat there stranded alone on this busy highway trying to get my vehicle to start back up. The brakes lock up and the vehicle completely shuts down. Each time I try many times to get my car started and it takes many attempts to crank the vehicle. I asked my service agent about the problem and he was unaware. He said they would have to drive the car to see if it happens with them and there is a diagnostic fee for this. I declined because it does not happen every time and I felt quite sure it would not happen when they were looking for it. This malfunction is sporadic.

The auto engine idle stop fails to restart the engine after stopping at stop lights, stop signs, in traffic, etc. Even after repeatedly "working" to turn off the car and turn it back on, it can take up to 2 minutes to effectively turn off the car so it may be restarted. This feels extremely dangerous at stoplights, but especially when caught in stop and go traffic on the highway or on a bridge. Cars go around into the intersection, honk, and when traffic picks up from the stop-and-go situation, cars drive by at high rates of speed while I sit motionless in the middle of the highway. While I more often than not remember to turn off this "feature" when starting the car, there are times that I forget. It has been horrible for my newly licensed driver. The anxiety and stress this has caused has led to learned anxiety while riding in and driving other cars that do not have this "feature." The problem was first reported to my local dealer in 2021. Today I asked the dealer to look at it again, while the SUV was undergoing a fix for the hood recall, and I was informed it would be a $140 diagnostic fee and then whatever the cost would be to "fix" observed problems. The dealer has not documented my complaints about said problem, though they ran diagnostics and indicated that the starter and battery were operating according to spec. They "reset" the system in November, but it did not help with the problem quickly reappearing.

When the light turned green, and I let my foot off the brake, the engine would not restart, as if the battery were dead. I put the car in Park, turned it off, turned it back on, and was able to restart the engine. This happened in about March of 2021. Since that time I always disable Auto Idle Stop, as it may create an unsafe traffic condition or accident if this were to happen in traffic. I was going to replace the battery, but have not done so since the occurrence 16 mos. ago, and have had no other issues with the battery in that time.

Today (8/2/22) is the second time this has happened to my vehicle: The engine fails to restart on its own from a complete stop at a traffic light or road intersection with the Auto Start/Stop function engaged. My car died, with bare components still working (windows and a few lights came on - battery and oil), but I was in the middle of a busy intersection when this happened, which is also a few feet away from a railroad crossing, which would have endangered the lives if others were behind me if they failed to pay attention to my hazard lights - which they did). My battery was replaced at the Honda dealership in April 2021, so it's less than 2 years old. A jump was required for the vehicle to restart and is now at Germain Honda of Dublin (again) for inspection of the issues.

I was stopped at a red light. The stop idol engaged and the vehicle did not start when I attempted to make my turn. The instrument panel indicated that I should shift to park. I did so and attempted to restart the vehicle but it did not start. After a number of attempts to restart it eventually turned on and I drove straight home. I was in the middle of a major intersection with my son in the car. Car zooming by me as my car was stuck in the turning lane. If a car failing to start as a result of a feature that was integrated by the manufacturer isn’t a safety issue then I don’t know what a safety concern would be classified as according the this institution. Permanently shutting off the feature is not an option as it renegades every time you start the car initially. The car has stalled a few times prior to today’s incident but this is the first time it failed to restart. As I drove home I reengaged the system to see what would happen, if failed to restart again and began the stall every time once the idol stop was engaged. This is unsafe. If I forget to turn off the function of this feature and I am on an expressway what happens if the car fails to restart, my brakes lights may not be pressed as I am thinking I am simply going to drive off and I could get rear ended at 60 miles an hour. This is a safety issue. This is a ticketing time bomb and further delays are putting thousands of lives at risk. I did I not know about the problem until I research the internet to find a solution. Why haven’t we been informed of this problem? Is this institution waiting for the body count to be high enough to warrant a consumer alert? This is a safety issue.

4PE25008 · Engine Failure
Opened Aug 20, 2025 · No close date supplied
Status: open (inferred from source dates) · Engine
The Office of Defects Investigation (ODI) has received 414 reports of connecting rod bearing failures in the 3.5L V6 engine used in the following vehicles: Model Years (MY) 2018-2020 Acura TLX, MY2016-2020 Acura MDX, MY2016-2020 Honda Pilot, MY2018-2020 Honda Odyssey, and MY2017-2019 Honda Ridgeline. The subject engine failures were analyzed as part of a Recall Query (RQ24013). It was determined that these engine failures are outside the scope of Honda Recall 23V-751. Further, evidence gathered in conjunction with RQ24013 does not suggest this failure is caused by the same crankshaft manufacturing defect that is addressed by Honda in Recall 23V-751. Based on analysis of data from RQ24013, NHTSA has closed that investigation. The significant number of reports of engine failure in vehicles outside the scope of RQ24013 presents a potential safety risk that warrants further investigation. ODI is opening this Preliminary Evaluation (PE) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

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.

RQ24013 · Engine Failure
Opened Nov 8, 2024 · Closed Aug 20, 2025
Status: closed (inferred from source dates) · Engine
On November 8, 2024, the Office of Defects Investigation (ODI) opened Recall Query RQ24013 to assess the scope of Honda recall 23V-751 after receiving complaints that alleged connecting rod bearing failures in vehicles that were not within the scope of recall 23V-751. In November 2023, Honda recalled 248,999 various Model Year (MY)2016–2020 Honda and Acura vehicles equipped with the 3.5L V6 engine. Honda recalled these vehicles due to a crankshaft manufacturing defect that caused premature connecting rod bearing wear and engine seizure. While the out-of-scope failures involved in these complaints appear to have a very similar failure mechanism as the recalled engines, a thorough analysis of all available data from Honda has not indicated that the same manufacturing defect exists in the out-of-scope engines as the engines recalled by 23V-751. Based on this analysis ODI has determined that Honda has properly defined the scope of recall 23V-751. Consequently, ODI will close this RQ investigation. NHTSA will continue to investigate these complaints of engine failure as part of a new Preliminary Evaluation Investigation (PE25008). The Agency reserves the right to take additional action if warranted by new circumstances.
