Was stopped at a very busy intersection today (2/12) and the vehicle's auto start/stop turned the vehicle off. When the light turned green, I attempted to apply gas and the engine stalled out. Was unable to restart the car again after many retries. I was very concerned that another vehicle would hit me since we were at a very busy intersection. All the electronic warnings on the dash appeared to flicker on and off when trying to restart. Eventually had to have the vehicle towed to the Honda dealer since the vehicle could not be jump started or restart on it's own.

Car turns off at stop after auto shutoff will not restart

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. //////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// This is an extremely dangerous vehicle malfunction and needs to be addressed as soon as possible before someone is killed. /////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// While driving on the freeway or highway, traffic comes to a complete stop, the engine idle feature stops the engine, and upon restart, the vehicle stalls. This leaves my wife and kids stalled, sometimes on the freeway for up to a minute until my wife can get the car restarted. During that minute, she's at risk of being hit by other motorists traveling at freeway speeds. ///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// I brought our Honda Pilot to the dealership, and they could not diagnose and fix the issue.

The auto stop/start does not restart after stopping at a red light.

- New Albany, PA, USA

Engine Idle Shutoff engaged while at stoplight, however, upon removing foot from brake and attempting to move along with the greenlight signal the vehicle failed to restart. This is the second occurrence with this vehicle since 2018. Engine failed to restart for several minutes while dangerously blocking moving traffic on a busy city street.

For the past couple of weeks, I have seen an quick error message (flashes and then disappears) and my Pilot has hesitated upon restarting after the auto engine idle stop has engaged at a stop sign. This was a longer hesitation (almost a failure to start) than the typical hesitation I feel when this feature engages. Yesterday, an error message stayed on the information screen, warning me that the auto idle stop feature was not working. This morning the error message was not there on startup. When I was at an intersection, my Pilot failed to restart after the auto idle stop feature engaged. It took a couple of attempts (pushing the start button) before the vehicle restarted and I could resume driving. This is a safety hazard for both me and other drivers. I have not yet taken the vehicle to the dealer for inspection.

My 2017 Pilot Elite has been suffering repeated issues with stalling out / engine not turning back on due to some sort of issue with the stop/start function (which will automatically turn the vehicle off when the break has been suppressed for more than 3 seconds). This is extremely dangerous and has put myself, my family, and others on the road in harm's way on multiple occasions. It appears that both NHTSA and Honda are both well aware of this issue, but for some reason are not moving forward with formal resolution despite the severity.

The contact owns a 2017 Honda Pilot. The contact stated that while her husband was driving approximately 5-10 MPH, the vehicle stalled at an intersection. The contact stated that while driving, the engine seized. There were no warning lights illuminated. The vehicle was taken to the local dealer but was not diagnosed or repaired. The manufacturer was not contacted about the failure. The approximate failure mileage was 96,000.

I am reporting 2 safety issues in this report, both involving the AUTO STOP/START function in my car. SAFETY ISSUE #1: MALFUNCTIONING AUTO STOP/START (ASS) FUNCTION: At least 4 times during the past 2 months, I have had a serious safety issue with my 2017 Honda Pilot wherein it stalls and is completely inoperable for a short time, while I-??m stopped at an intersection. This has caused me undue stress and jeopardized the safety of myself and my passengers, and disrupted traffic. According to my best recollection, the situation occurs when the ASS function stalls the engine (when stopped), and I manually press the -??Disable ASS-?? button to restart the engine. But instead of the engine turning back, all systems completely -??black out-?? as I frantically try to re-start the engine, to no effect. After several scary seconds, somehow it re-starts. SAFETY ISSUE #2: CORRECTLY FUNCTIONING ASS FUNCTION: Even when functioning correctly, the ASS function has caused a safety issue for me at least twice. When the ASS function was automatically engaged, I was unable to immediately accelerate to avoid a potential collision. Although no collision resulted, these few scares -??trained me-?? to manually disengage the ASS function whenever I remember to do so. Based on my experiences, It would be safest to have no ASS function at all.

The auto start stop function has failed multiple times on this vehicle in different situations with multiple different drivers. When my mother in law was driving my vehicle with my kids in the car the vehicle would not restart at a stop light in the middle of town with moderately heavy traffic. It took several tries to get the vehicle started again. This has happened to me several times at stop signs and traffic lights since I don't primary drive the vehicle I forget to turn off the auto start stop function. It has failed several times on my wife as well in similar situations. I have not brought this to the dealerships attention due to no fix available and not want to pay to have them tell me the same thing I already know.

Auto Start does not work. Car frequently stalls when in traffic or at red light and fails to auto start when removing foot from brake.

The issue with our 2016 Honda Pilot pertains to the Auto Start/Stop feature. The pilot began stalling out after being at stop signs/traffic signals and the vehicle would attempt to re-start and then stall. When stalled it was very difficult to get the car restarted. On several occasions, the vehicle has stalled in the middle of intersections which has been highly dangerous as the vehicle was stalled for several minutes. We have first logged a complaint with the Honda dealership on 06/10/2020. The dealer claimed it could not replicate the issue. We filed another complaint on 04/23/2021 as the problem persisted. The dealer, again, claimed they could not replicate the issue and then stated we needed a new car battery. The dealer is not being honest as we took our vehicle to a local mechanic (Henn Automative in Waxhaw, NC) for general servicing and he called us to inform us of a dangerous problem with the Auto Start/Stop. This independent service center performed their review on 12/20/2022. He alerted us that a formal action number had been opened by ODI under -??PE22005-??. Currently our fix is to disable the Auto Start/Stop feature every time the vehicle is operated. In rare occasions when we forget to do so, the vehicle stalls consistently. There have been no alarms, warnings or the like. I believe the dealer & Honda are well aware of this problem but have not garnered the necessary resources to address the issue and pretend that their customers are imagining these occurrences.

This vehicle is equipped with an "idle off" feature meaning the engine stops for a period of time when the car is at zero speed (for example a stop light) then restarts when the brake is released or the steering wheel is turned. In 3 separate instances, my vehicle has stalled during the re-start process. The vehicle will restart for a second or two moving about 5 feet then stalls bringing the vehicle to an abrupt stop. All instances have occurred in or approaching an intersection. Once stalled, the vehicle will not re-start immediately, it takes approximately 15 to 30 seconds to get the vehicle restarted. All 3 incidents have posed a safety concern for myself and other people traveling behind me.

Approximately 6 times in the last several weeks the engine of my Pilot has auto shut off at a stop light but then it will not restart when I try to go. I have to shut down the whole car and it takes several tries to get it restarted. The most recent time it would not restart for several minutes. I am then stuck in traffic unable to move. I have to remember to disable the auto shut-off/restart or this occurs.

Auto-stop feature failed to restart vehicle after auto-stop was engaged at a stop light. When letting off the brake, the auto-stop disengaged, but the vehicle engine failed to start, posing a safety risk as the vehicle did not restart in heavy traffic. This has been reproduced numerous times by the owner, but not by a dealer or independent service center. The component has not been inspected by the manufacturer, but the owner is an ASE certified mechanic. Warning lamps illuminate after vehicle fails to start, but the only way to restart the vehicle is to shift into park, completely shut off the vehicle electrical and attempt to restart. The system is receiving appropriate recharge from alternator, and battery is in acceptable condition.

On Sun NOV 13th, 2022 I was on I-75 going north and had to slow down and then stop at a 'stop and go' traffic in the beginning of or just before the construction zone. With my foot on the brake, complete stop on the highway, the Honda Pilot suddenly went into Neutral and I was unable to put it in drive mode. I panicked, as there was a lot of traffic behind and I put the blinkers on, put the vehicle in park, tried to restart and didn't work. After a couple of tries, fortunately the engine restarted. In the middle of the one lane construction, I had to stop once again as the traffic was stopped. Once again the Pilot did the same thing. It stalled, and I had to restart the engine. It was very scary and a big safety problem. I have placed a call into Honda service but no response as yet. It is scary now to stop at red lights and stop signs! It happened 2 times in the same construction zone within 5 minutes.

The engine would not restart at the red light. Start/Stop system was active, came to a red light and the vehicle turned off as normal with my foot on the brake, when the brakes were released the vehicle did not restart and I heard a click sound. I had to manually(push the start button) to completely turn off the car and then press it again to start the car. I had my entire family in the car including my child, with vehicles behind me on a main multi lane road. I almost got rear ended due to this malfunction.

Problem with the auto engine idle stop system. With the Honda stopped at a traffic light, the engine turned off completely and pressing the accelerator pedal did not restart the car. And continually pressing the Start button didn-??t start the engine, either.?It has happened three times so far. My family and I were unexpectedly immobile in the middle of traffic, with vehicles driving around our stranded automobile. We were nervous that an accident would occur. The brake pedal locked and I had to press the brake pedal firmly numerous times before the Start button would allow the car to start.
