My 2016 honda pilot will not restart after it idles at a stoplight. This has happened multiple times and is happening more frequently (twice today). Both times today I was in a line of traffic and was in fear that someone behind me would hit me. The dashboard message said to put the car in park but that did not work. I had to turn the car completely off and restart it. The second time it took me three tries to get the car started. The guy behind me was very angry, gesturing and yelling. Road rage is scary too. I had the car looked at several months ago due the same issue and they could not find anything wrong when they ran diagnostics. I cannot recreate the problem on demand. It is sporadic. And scary.

My 2016 Honda Pilot has been experiencing an issue with the auto start-stop system, in which the vehicle's engine fails to restart after a stop and/or the dashboard indicators flash on and off with multiple error codes displaying. This has happened many times on the highway and on streets, one time where it would not restart on the highway and cars were going around me on both sides which was very dangerous. I reported this to Honda corporate and opened up a case, which was open for many months while the Pauly Honda dealer in Libertyville, IL and the Muller Honda dealer in Gurnee, IL tried to diagnose the problem. They ended up trying several fixes, including replacing the battery, but nothing has fixed the issue. The dealer also contacted the engineers at Honda Corporate, and they indicated that they were not aware of the issue and have not been able to provide any fixes. This is still an issue today, and the only workaround I have is to disable the auto start/stop function manually, every time I start the car. Dates: - I checked and we actually brought our car into Muller Honda of Gurnee in September 2021 where we reported an issue where "C/S (customer) feels like it wants to die coming to a stop. Dash lights turn off like vehicle died. All displays go dark." They felt that it was "Caused by: Technician verified keyless remote system problem light on dash. Tech found code B12C5 stored in system. Corrected by (Y9300) (6S100) Warranty extension. Keyless start system error with DTC B12C5. BulletinS". This did not fully resolve the issue. - Then in October 2021 we brought the car into Pauly Honda of Libertyville where we again reported the same issue where "Customer states in eco mode the center screen now goes blank then cycles and comes back on." This did not fully resolve the issue. - Then in the spring of 2022 we brought it back to Pauly Honda as more severe issues started occurring. I also opened up Case #13103604 with Honda Corporate.

When driving and stopped, the fuel saving features shuts the engine off to save fuel, it should restart the engine after letting your foot off the brake. At least 25 times now, the car fails to restart. In a panic, you have to put your foot back on the brake, put the car in park, restart the engine by pushing the start button, then put the car in drive before you can resume. This has nearly caused us to be hit by other vehicles that assume you will start to move when traffic resumes. On the interstate there was an accident ahead and the car did this when a semi was moving at great speed toward us with our family. I-??m not sure this car is safe. The Honda service department suggested we have valves adjust at a cost of $700-$800 claiming that could help. There are no warning lamps. The car has had the battery replaced in the last year and starts every time, the first time when we begin a trip. Our teenagers can-??t drive this car due to this safety issue. This started about a year ago and is becoming more frequent. It happened three times in the last week.

Repeatedly, the engine idle auto-stop function fails. The dealership and authorized Honda repair facilities say it is a known issue to them but not acknowledged by Honda. They state it must be due to driver error. When this function fails, it is random and creates an immediate emergency situation. The engine auto-stop feature is on by default. We try to remember to turn it off every time. But when we forget, we come to any stop (light, traffic etc), the engine will go from idle to stall! No notice, no warning, no indicator light. The car will completely turn off with the car in drive. You need to put the car in park, try to restart the car, get back into drive and hope an accident doesn't occur. We have a college teen now who drives this Honda Pilot. Soon to have a High School teen. They do not have enough driving experience to react to something like this. My fear is that a serious accident may incur. Last year this same engine had some type of issue where every light on the dashboard would light up. Apparently a know problem with a defective fuel injection system. We were never notified about this issue from Honda. Honda repaired it at no cost but, it was another know issue about a major engine flaw. Now this auto idle which is going out of control. Honda needs be accountable before fatalities occur. This car is becoming a lemon.

About a year after we bought the car the engines fail to restart after stopping, in some cases the jump start was required to get the engine going again. After it happened on the highway a few times we took the car into service and they said it was the battery they changed the battery which cost us a lot of money. After changing the battery it happened over and over again, we took the car again into service and they said it is not related to the battery and that they shouldn't change the battery in the first place. They said it's a software issue and they updated the software and we paid a lot of money and the problem continued. We report the issue every time we take the car to a car maintenance and they say it's a Honda problem and they can't help us (the service we go to is Honda car service). Whenever there is traffic we are afraid the car will stop and we will cause a collision. No warning lights before the failure.

I was exiting a highway and entering a right hand turn lane. There was traffic in the turn lane and I came to a complete stop. When I stopped my car shut down. I attempted to restart by pushing the engine start/stop button but the car did not restart.

When at a stop, t he start/stop feature is enabled and the engine shuts off as expected. When I lift my foot off the brake, it doesn't always restart, and I am left stranded in an intersection or at a light, and almost in accidents. Very unsafe. I have to turn it off every time I get into the car. When I forget to turn it off, it always fails to restart.

For years, dating back to 2018, our 2016 Honda Pilot Elite auto on/off switch operations has been failing. Vehicle will not restart the engine after its engaged the auto start off. Engine and all components including electrical are off. Dashboard indications light up and essentially we are stalled, at risk of not being able to drive. It requires to place the car into park and restart the engine. This is serious safety issue that could result in being struct by another vehicle without being able to move. I have been taking the car to several authorized Honda service dealerships to address the issue. They have replaced multiple times the auto on/off switch, battery, adjusted values and updated software with no resolution. One dealership claimed to disable the auto on/off switch but this is NOT feasible. With the latest inspection, another local Honda dealership contacted Honda Corp Tech Line for assistance. Once again they instructed the dealer to perform all the potential fixes above and to ignore a code P2638. After investigating this online, Honda and NHTSA have opened an investigation June 2022 on this issue after 220+ complaints. There is no known fix, yet Honda Corp Tech Line informed local dealer to conduct value adjustments yet again, at a labor cost to us.

- Arlington, TX, USA

The engine's idle-stop feature shut off my car while stopped at a busy intersection in urban traffic, and took 15 seconds to restart the automobile. The idle-stop feature kicked in when at an intersection. When I took my foot off the brake to accelerate forward, the car instead turned off. The dashboard prompted me to shift the car into park, put my foot on the brake, and press the engine ignition button. I did so, but the car did not restart, even when I repeated the process 2-3 times. Finally, on the fourth time, the car restarted.
