2018 Honda Pilot: start-stop system problems

Filed Aug 22, 2025 · Engine · IL

Although I had the Honda taken in for the prior auto stop/start engine recall. The software fix has not solved the issue. While in traffic, even with the auto stop/start feature OFF, the engine will randomly turn off and it becomes a safety hazard as I’m blocking traffic scrambling to turn my engine back on, sometimes it is challenging to get the engine back on, and in the meantime cars are driving all around trying to get around me. This is ridiculous that Honda is doing the bare minimum to address what is clearly a huge liability for me as a driver and others in traffic.

Auto restart failed. Vehicle failed to move forward at a red light. Dash instructed to place vehicle on park then press the engine start-stop button hence restarting in the middle of the road presenting a safety hazard, cars behind me almost tail ending mine. People were honking and I couldn’t move fast enough. Why is the Honda dealer saying they will charge $222 to inspect to see if it’s a starter issue? Just fix the problem. I already had the system reset due to recall. This is a prevalent problem, shouldn’t it be inclusive to a recall. Also putting the customers at risk knowing its an issue is a huge problem. Please advise and help resolve this safety issue.

There is an auto start/stop feature on my 2018 Honda Pilot. I’ve owned it new since July 2018. My wife and I have experienced the same issue both together and separately. The auto stop feature will engage with the break depressed, but the auto start function will not always engage when the break is released. This has left us stranded in the middle of intersections in the middle of left turns with oncoming traffic driving around us, stalled on the freeway with cars whizzing by us at 70+ MPH blocking the fast lane, blocking congested one lane roads with no recourse for drivers behinds to get around us, etc. This feature stops the engine but periodically does not allow it to turn back on. With the engine stopped by this feature, but not shifted to park/ neutral, pressing the ignition start/ stop button does nothing. Shifting to park, and pressing the ignition start/stop button significantly delays removing the road hazard now created by the vehicle’s now dangerous location. To further complicate the matter, the engine starting has, on many occasions, taken multiple minutes to start, endangering myself, my wife, my four children, and other family / friends on too many occasions to count. My local dealership recommended replacing the vehicles battery, even though I had no other battery related problems. I did, in fact, follow that recommendation, only to have the same problem persist. I have encouraged my wife to disengage this feature proceeding forward, but the feature automatically resets itself everyone the ignition is started. This becomes problematic if the feature is forgotten to be turned off or, due to placement of the features button, the feature is inadvertently re-engaged.

While driving my 2018 Honda Pilot I stopped in an intersection to make a turn and when I came to a complete stop my vehicle stopped running. Assuming it was the auto start/stop I released the brake and attempted to accelerate to complete my turn the vehicle failed to re-start and shuttered / stalled. I then could not get my vehicle to restart and had multiple warnings on my dash along with check engine light being lit. 1 of the errors showed "Emissions System Problem" as well as "Move vehicle to side of road and park". I could not get the vehicle to do anything even though it was already in parked from stalling out. I had to press Start/Stop button to turn my vehicle off completely for approx. 2 minutes and then was able to get vehicle restarted and then shifted to Drive to clear intersection. This has happened multiple times in different circumstances. I have had the vehicle back to Honda dealership twice and they said the do not see any issue or cannot get issue to repeat.

The contact owns a 2018 Honda Pilot. The contact stated that while his wife was stopped at a stop light, the vehicle inadvertently lost motive power; however, the vehicle was able to immediately restart. After restarting the vehicle, the vehicle returned to normal functionality, but the failure became a regular occurrence. The STOP/START warning light was illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 94,000. The VIN was not available.

The vehicle's auto stop/start function shut down power to the engine at an intersection and would not restart. The vehicle was unable to move at a busy intersection and would not manually restart either. A dealer or independent service center has not reproduced the problem, but I do see plenty of other cases on different automotive forums. The vehicle has not been inspected by the manufacturer, police, insurance, or others. There were no warning lights or other symptoms prior to the engine shut down. This has happened on more than one occasion and usually in the summer months when the A/C system is running. It doesn't seem to be an issue without the A/C running. Thank you

As of 11/21/23, our honda pilot has approx 75,000 miles, we purchased it new so we are the only owners. A few weeks ago, the vehicle while driving about 45 mph, completely shut off, all lights on the dash cam on and the transmission became disengaged. We were able to shut it off for a few minutes, and drive it about 1/2 mile to the local Acura dealership. The car did not operate normally though, it would only go about 20-30 mph, before the transmission disengaged for a few seconds, then re-engage and continue driving. Acura said it was a producing a bad cam-shaft sensor code, they reset it, but said if it happened again, they would need to open up the engine to inspect the cam-shaft. Two days later, the exact same thing happened, we returned it to the same Acura dealership, where they said the cam shaft, and abunch of other parts needed replacement, at a cost of about $2,500. We had no choice since the car was immobilized. Now, the week of 11/20/2023, a recall regarding the rod bearings was issues, which cause the exact same immobilization issues we experienced, which is very dangerous as a driver. Upon research online, the cam shaft sensor and faulty cam shaft is more common than I expected, and I believe should be investigated before someone is seriously injured. To add, our specific pilot is not showing the engine rod recall, but we have experienced issue with the vehicle in regards to the auto start/stop feature and the car not restarting, as well as cruise control issues where the car will go into neutral at 70+ mph when cruise control is activated. We will probably not have this vehicle much longer because of the issues we have had in the first 75K miles, and the continued safety issues that plague this model. More needs to be done for the safety of it's drivers and passengers.

While stopped at an intersection, the vehicle's Auto Start/Stop technology engaged. When driver attempted to drive, the Auto Start/Stop wouldn't disengage, as a result the car would not start. The vehicle prompted the driver to put the car in park and push the ignition button to start the car, however nothing happened, meaning the car would not start. After about 2 minutes, the car was able to start and the driver was able to continue driving. An immobilized vehicle at an intersection put its passengers at risk, including 2 children under the age of 3. Dealer will be notified of this occurrence.

Vehicle auto start/stop feature actually shuts the car off (at times) and requires me to put the car in part and go through the car startup process. This causes issues when you’re at a green light. I have taken the car to Honda and so far they’ve performed a software update, replaced the starter, and tuned the valves.

he auto start/stop is not working for my 2018 Honda Pilot Elite. The vehicle does not start in the middle of the traffic when it stops. I've stuck stuck multiple times and now for last 1 year I have to force switch off that feature every time I drive the car.
