I have experienced several instances where the vehicle's auto stop-start system fails to restart the vehicle's engine after a stop. This has happened 2-5 times. Specifically, when the vehicle is at a full stop (with brake fully depressed), the auto stop-start system is designed to stop the engine to conserve fuel by turning the engine off. During the episodes at issue, the system works correctly to stop the system. However, when I have released the brake pedal and attempted to resume driving, the engine has failed to restart and the power system appears to fail/reset. The vehicle then requires that I attempt to restart it using the stop/start button. On at least one occasion, I had to make multiple attempts to restart the vehicle before it finally began operating again. This situation often results in the vehicle obstructing traffic for an extended period of time and creating a dangerous situation. I have begun disabling the auto stop-start system when driving the car to avoid this problem occurring.

My car completely shuts off at stop sign/red light when engine idle feature is activated. I have to put car in park and restart it. This has been an ongoing issue since summer 2021. Vehicle was evaluated at dealership with no resolve. In addition, a new cam shaft had to be installed in fall 2022, at Honda's expense.Car completely stalled while passing another (55mph)

- Sylvania, OH, USA

Vehicle would shift into neutral upon acceleration such as when passing and take up to a minute to reengage in a gear to continue acceleration. Generally happened at 50-60mph on the highway. Called dealer multiple times and brought in at 47,000 mi, but no codes generated by vehicle and dealer couldn't replicate. Finally at 81,000 transmission completely failed on a busy highway exit ramp and car could not be put in gear. Blocked traffic for 2 hours before car could be towed to the dealer. It appears Honda had transmission based recalls up to 2016 but not 2017 model year.

The contact owns a 2017 Honda Pilot. The contact stated that while the vehicle was idling at a stop light and attempting to proceed to drive, the accelerator pedal was depressed; however, the vehicle lost motive power and stalled. The contact shifted the vehicle to park(P) and restarted the vehicle. The failure only occurred whenever the Auto START/STOP function was activated. The contact took the vehicle to the dealer who diagnosed that the fuel injector failed and needed to be replaced. The failure persisted. The contact returned the vehicle to the dealer who then diagnosed the vehicle and determined that the torque converter and converter clutch failed and needed to be flushed or replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 56,000.

Per PE 22-005, with Auto Idle Stop enabled, when coming to a stop light, I stopped. 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.

Driving on the highway, came to a stop due to high volume of traffic, car stopped completely and auto/start turned off the engine itself like it should when brake is stepped on all the way, traffic started to move, let go of the brake to have engine turn back on like it normally would, however this time the engine did not start back on itself, tried to step on the brake and would not allow to press on it. Hit the engine start button light would come on however brake still would not allow to be stepped on, its like it is stuck. Tried this for about 5min and suddenly I was able to press on the brake and start the engine by hitting the start engine button. The component that failed is the engine, auto/start feature, power train, and electrical system. This was a big safety issue and yes it would not only put myself at risk but others safety at risk too. No the problem have not been reproduced or confirmed by a dealer No the vehicle or component has not been inspected by anyone No there was no warning when it first appear, it just happen.

At least once a week the vehicle shuts off and don-??t restart at stop light/ sign.

This car has an automatic start/stop feature/function that shuts the engine off when the brake is fully pressed. The purpose is to save fuel when stopped at a red light or in heavy traffic. As soon as you release the brake, the engine is supposed to restart automatically. Unfortunately whats been happening is either the engine does not restart or it begins to restart and then stalls. In either case, the car needs to then be put into park, fully turned off, and then restarted. In most cases, it more an annoyance for everyone involved. However, what has happened a number of times is that we-??ve moved into an intersection to make a left, stopped for oncoming traffic to pass, and then started our turn. The car has stalled then. Luckily there has been no accidents, but that is by luck. As the lights change, we have to quickly restart and get out if the intersection. I-??ve searched online for a solution. Many people have post about the same issue in various forums. Many have also taken their car to Honda dealership for service, but there has been no consistent response as to the cause or a solution. In more recent models, Honda has changed how this feature works, but they have not provided any solution for models preceding the change. Thank for any resolution you can bring to us the many others impacted by this point problem. FYI this is not an issue on a single date; it is inconsistent but recurring.

When the engine stops when the brake is applied, there are times when the engine shuts down completely, restarting electrical systems and not starting up again. This incredibly scary and dangerous. I have brought it to the dealer who has no idea how to fix it. I read an article that this is something the NHTSA is investigating and am very relieved that there is finally some attention being paid to this problem. I wanted to log my vehicle as being effected also.

Engine does not restart after start stop feature {auto stop} when stopped at a stoplight or stop sign. Sometimes engine turns off with just a soft application of brakes. So far no serious accident except holding up traffic at an intersection. Could become dangerous. So I immediately turn off the feature whenever I remember when I get in the car. Thanks.

We were at a Sheetz gas station last month and the auto-start/stop cut the engine off and it would not restart. We had to place the car in park and manually restart it. We have had this issue happen on another occasion and we purchased the car in April.

At start up, both with remote start an manual start, the vehicle will lurch forward. It seems to be happening with more frequency for a total of about 10 times. My worry is that at start up the vehicle will strike nearby pedestrians or property. The transmission has had start / stop issues and -??hard-?? shifts but the dealer has not found any issues. There are no warning lights associated with this issue.

For the past few months, I have been having issues with my vehicle stalling. This issue occurs while stopped at red lights, stop signs, and while sitting in stop and go traffic. My vehicle is equipped with the Auto Start/Stop feature, and while stopped at a stop sign for instance, the vehicle will auto stop but fail to auto start when taking my foot off the brake and hitting the gas. This has happened on numerous occasions, putting those in the vehicle and those in other vehicles around my vehicle at risk. I brought my vehicle to my local dealership, at which point they checked it and found nothing wrong with the vehicle. They also stated that they, and the vehicle manufacturer were aware of the issue, but have no solution for it. The first time I brought the vehicle in, the dealer told me that a possible fix was an update to the system, however I would have to pay for the update. After the service adviser spoke with the service manager a few times, the dealership paid for the $220 update. The vehicle has since continued to stall, the only thing that seems to assist is to turn off the Auto Start/Stop feature every time the vehicle is turned on. Last Thursday, the vehicle stalled again on my wife with our son in the vehicle at a t-intersection. The vehicle failed to start for approximately 10-15 minutes. I contacted my dealer again and was advised to bring my vehicle in. I brought it in and was told that I could have a rental car, but that I would need to approve paying a $160 diagnostic fee. They were unsure of a permanent solution for the problem.

Traveling about 70 mph on the interstate using cruise control. I don-??t think there was a change in steepness/grade, but if there was it was mild. Suddenly, the rpm-??s were erratic and the engine and gears seemed out of sync. Pressing the gas pedal didn-??t seem to effectively accelerate the vehicle. I don-??t believe the brakes were affected. The -??D-?? for drive indicator kept blinking on and off. Multiple warning lights on the dash display: transmission system problem, all wheel drive problem, and interestingly, blind spot monitor problem. The last indicator to show was emissions system problem, and this indicator remained on the screen. I exited the interstate. Shifted to reverse, then parked the car and turned engine off. After a few moments, I restarted the engine and the only anomaly I observed was the warning indicator light on the dash read: emissions system problem. There was roughly 1/4 to 1/2 tank of gasoline remaining at the time of incidence. I continued to drive approximately 350 miles more to my destination, without using cruise control and without further or other issues. I made a couple stops to add gas and both times the engine was turned off then back on again without issue. The following day, after restarting the engine, the -??emissions system problem-?? warning indicator light was no longer showing on the display. I have yet to encounter the problem thus far, but I haven-??t used the cruise control since nor have I driven at interstate speeds for any considerable length of time. I haven-??t yet taken the vehicle to the dealer for inspection. But will do so.

When slowing down to stop at a light, or pull into a parking space, the vehicle rather than braking and stopping, accelerates violently on its own, and there is no way to stop it other than putting the vehicle in park immediately, or slamming on the emergency brake. This is an intermittent problem. It happens once every few months, however last night it occurred and I did not put it in park quickly enough, and I was close to another vehicle while parking, that I slammed into the other vehicle doing extensive damage. Obviously, this is a very dangerous situation that could kill or maim myself or an occupant of another vehicle; the police officer who happened to own the other vehicle said I should not drive my vehicle until the problem is solved, which, of course, makes sense as my vehicle at present is unpredictable and dangerous. I have now taken the vehicle into the dealer, but I've found in the past these intermittent problems are difficult to diagnose. Should it not be diagnosed and fixed--I noticed that others have had this same vexing and dangerous situation, and it was not fixed or resoved to their satisfaction--I will no longer drive the vehicle as it is too dangerous. There seems to be a glitch with the drive trains/engines of the 2017 Honda Pilot and this needs to be fixed and the vehicles recalled before serious injury occurs, if it has not already. Owners of these vehicles should be compensated, or receive a comparable vehicle that is road worthy.

In the past week, my Pilot has stalled for no known reason. Both times the vehicle was stopped and the feature that idles the car down to conserve energy was activated. When I let off the brake instead of the car restarting or gearing up and accelerating, the car just died. Warning lights went off on the dash, but the car wouldn't restart for at least a minute both times. No warning lights were on the dash before the incident and after the car restarted, no warning lights remained lit on the dash. I took my car to an automotive store and had them check the battery, the alternator and the starter - all of these came back as being in perfect condition. I was extremely scared when both of these incidents occurred. One time I was at the bottom of an exit ramp of a busy interstate and the other occurred on an interstate in stop and go traffic. In addition to these two incidents, for the past 2 years, the car has been having issues after it idles down and then should restart and accelerate. About 2-3 times per month, when the car is stopped and has idled down, when I let off the brake and accelerate, the electrical system will flash on and off. The entire dash goes dark, the audio goes off and comes back on, etc. The entire electrical system reboots. When this happens, it does not impact the ability of the car to accelerate because it is more like a flash - the car doesn't die and have to be restarted. I am taking my car into the Honda dealer on Monday to attempt to diagnose the problem, but from the research I've done, may other Pilot owners are having the same problem and their dealers aren't able to find an error code caused by these issues. I have been attempting to get a video of this when it happens, but so far, I've been unable to reproduce the issue.

My vehicle is a 6 speed automatic transmission, which is experiencing symptoms known to affect 9 speed transmissions as documented in TSB 20-029, Hard Upshift with Steady Acceleration. The transmission has intermittent harsh or jerky upshifts with steady acceleration. The vehicle will 'clank' and jump slightly forward, while accelerating between 20-45mph. Does not happen always - have not determined a pattern.
