2017 HONDA PILOT Electrical System Problems

On multiple occasions, the engine idle stop system has failed to restart the engine at an intersection when releasing the brake leaving the car disabled in a dangerous situation. This started after about 20k miles. When it happens the car is fine until brake release. It seems to try to restart but the entire car loses power. No lights, no anything. Won't restart at first either. After a few moments trying to get it to restart it will fire up and you can put it back in drive and continue. I did note it happened less when I replaced the battery for a while. Dealer has replaced fuel rail and ignition switch to no avail. As a car guy I can say when it happens it's almost like there is not enough power to throw the starter. At that moment it's like all the power is sapped away like a...

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....

On numerous occasions, when the auto engine start/stop engages, due to coming to a temporary stop, the vehicle completely shuts down. I then have to restart the car manually. Usually a notification pops up on the dash telling me there’s an issue and you have to follow the instructions. It’s very stressful because I am usually in traffic and have my children with me. This is a huge safety issue.

I was stopped at a stop sign and the auto-idle engaged. When I went to start again, the entire car shut down and would not start. I told me to depress the brake to start the vehicle, but the brake would not depress. I was stuck at the stop sign in the middle of a busy intersection because the car wouldn’t restart after the auto-idle engaged. After about 10 minutes, the car was able to start and I was able to drive it home. Prior to this, I have had some instances where the auto-idle would engage and when I went to drive again, all the lights would flash and it would delay in starting. The code reader read zero codes. Previous inspections from the deal found no errors as well. We are replacing the battery, but there are no other indications the battery was dead, dying or faulty and...

The contact owns a 2017 Honda Pilot. The contact stated that alarm on the vehicle would activate erroneously. The contact stated that after deactivating the alarm, the alarm sounded again hours later. The vehicle was not taken to be diagnosed or repaired. The manufacturer was not contacted. The failure mileage was 100,000.

1. The problem is linked directly to the Auto Start/Stop capability. The Car is available for inspection upon request. 2. Car shut down electrically in the intersection of the road and caused traffic and police presence, semi trucks rolling through were frightening 3. Honda West Dealership in Las Vegas inspected the problem but had no resolution to fix it. 4. No warning lights indicated a shut off was emminent.

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...

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...

Failed to restart when auto engine stop engaged in the middle of a busy intersection. Large truck with heavy duty battery jump started but it took 10 minutes of being connected to the battery for the engine ignition to start again. No lack of charge (all electronics working but turned off just in case) but a defect in the restart after cutoff.

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...

We own a Honda Pilot 2017 Touring trim. I saw your news report that there is a document out there published by the NHTSA that is investigating this issue. I’d like to add my experience to this. On or about April 2022, we started experiencing the start/stop issue while living in Kansas. When the issue occurred, an error message would flash very briefly across the dash, quick enough where we could not take a picture of the message. Our Honda would stutter then start back up. At this point, we took it to the Legends Honda dealership [10050 Parallel Pkwy, Kansas City, KS 66109] and after a free diagnostic they told us they could not A) replicate the issue, B) find evidence of the error message in the system. The next week, we had a complete engine failure while at a stop light for a full 5 minutes. During those...

The auto restart feature fails to restart the car after releasing the break sitting at a busy intersection. The car information center provided information to put the car in park and hit the ignition button again. I was able to get the car to restart after several tries by putting the car in park, shutting it off and turning it back on. This the third time this has happened in the past month.

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)

Car stalls when auto stop turns back on

Vehicle stalls REPEATEDLY when the automatic anti-idle function is active. Whenever the air conditioning and audio is on and I stop the car, the engine stops (as the anti-idle system is intended to work), then stalls out as the engine restarts. This has been happening for about 2 years and happens almost every time the anti-idle system engages. It’s terrifying when it stalls in stop and go traffic on the highway.

In support of NHTSA Action Number: PE22005 2017 Honda Pilot multiple experiences with the auto idle cutting off and not restarting. 8/4/2022 was worst experience to date. The vehicle cut off at a stop light and would not restart. The ability to roll down the windows and unlock the doors was disabled so 2 occupants were potentially trapped inside. Fortunately a door had just been opened to waive backed up traffic around the disabled vehicle. AAA and Sheriff's were called to the scene. It was successfully jumped and the AAA diagnosis was that nothing was wrong with the battery, starter, nor alternator. This is a major flaw in engineering and a fix has to be developed or the vehicle appropriately replaced.

Starting in the summer if 2020 every few weeks after coming to a stop and the auto idle stop would stop the engine. When releasing the brake the engine would not immediately restart. The pause on restart would slowly increase as the time between occurrences decreased. Occurred during each trip. Pauses increased enough that the entire control panel and radio screen would go black, and then the car restarted with warning message coming up on control panel. Contacted Honda and took it in on 9/9/2020. They couldn’t recreate the issue. They charged the battery, did hard reset. Drove car with issue still occurring. Returned the vehicle for additional service on 9/16/2020. They are still unable to duplicate the issue and opened up a tech line case#4376911. They replaced a Dc/DC converter. Issue continued. Returned car with same issue. Don’t know date at this time. They replaced the battery which did...

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...

When stopping for more than a few seconds auto-idle stop turns off the vehicle completely and does not turn back on by pressing the gas pedal. Car must then be completely turned off, back on and shifted into drive to continue moving.

The problem is that which is reported here: https://static.nhtsa.gov/odi/tsbs/2020/MC-10184330-0001.pdf My problem is that I am being told that my VIN number is not included in the group eligible for the warrantee extension and fee coverage for the replacement of the keyless start sytem. Seeing how my vehicle is the model, make and year that this problem is known to effect, I am confused and frustrated by the inequitable and arbitrary use of VIN numbers as determinant of coverage. This is a known issue for 2017 Honda Pilots. My vehicle CLEARLY demonstrated all the malfunctions described and therefore, I believe it should be provided the warrantee extension and that I should not have to pay for the replacement ($168.17).

For several year I've had a problem with the fuel-saving stop-start system on my Honda Pilot. Unless I turn this system off each time I drive it routinely (several times a week) fails to turn back on after making a complete stop, usually at a traffic light or stop sign. This has placed me in several dangerous situations as cars are speeding behind me, not expecting my car to be at a dead stop when a green light turns. It takes several tries to re-start the car and causes chaos at intersections. I took the car to a Honda dealer and was charged $975 to replace the battery, which they said would fix the problem. I have also followed all the safety recalls and yet the problem persists. I wanted to file an official report because this faulty system is a major accident waiting to happen. Given that my car...

The auto idle stop function caused the vehicle to stop running, needing a full shutdown and restart. This happened on busy roadways, and it has happened two times with this vehicle, one time each in different years. I think the first time was in 2021 and the second was definitely in June 2022. We have had this vehicle into a dealership multiple times attempting to resolve the issue. Each time the battery has been replaced due to low voltage, and they were able to reproduce the issue at least once. The most recent time I was informed that Honda released a service bulletin recommending a change to engine compression that may be straining the battery when restarting the engine, but I am currently waiting on Honda to decide if they will cover the cost of this service before agreeing to it. We are currently operating the vehicle with the auto...

Vehicle does not start back up after auto shut off activates. It is also stopping suddenly on the road

The Auto Start/Stop feature on my 2017 Honda Pilot has had issues for the last 2 year. It started with the engine occasionally "hesitating" to restart after I held the brake pedal down at a stop light. As it started to happen more frequently, I took it to my Honda dealer and they told me that they could not recreate the issue and thus could not diagnose and fix it. Within the last 6 months, the issue has become more and more frequent and severe to the point that I have been worried about the car not restarting and have been manually turning off the Auto Start/Stop feature when I drive the vehicle. It does seem to occur more frequently in hot weather when I running the A/C and there is more of load on the engine and system. On July 16, 2022, I forgot to turn off the Auto...

The Idle-Stop system shuts off when the SUV is stopped for two or more seconds. There are times when I release the break pedal after several seconds or more and the car engine does Not restart on its owLast episode 7/2/22

Vehicle stalls in the middle of intersection while attempting to auto restart with the auto on/off feature. This has been happening since we boughe the vehicle new in 2017. Dealer said they could not simulate. Happens a few times a day.

When auto idle is engaged, the car SHOULD start when the brake is released after stopping. We noticed problems when we released the brake. The radio and A/C shut down and quickly come back on again. So release brake, radio and A/C shut down and then radio and A/C come back. Reported to Jeff Wyler Honda and I believe I have a video. As of yesterday, 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. You have to put your foot on the brake, shift to park and restart. This occurred twice in two days. Once at a traffic light and once after a traffic jam on the highway. It is scary especially the first time it occurs. It has the potential of leaving the vehicle in a stopped position in dangerous locations if...

--AUTO ENGINE IDLE STOP SYSTEM. Yes, available for inspection upon request. --SAFETY CONCERN- Engine stalls in the middle of traffic... causing other traffic behind car to become angry and try and pass the STALLED car. As they attempt to pass, they endanger other traffic. Usually happens during heavy traffic, breakdown then needs driver to restart car completely in mid traffic and missing or heavy delay of green light which could itself potentially cause an accident. --The STALL happens constantly 1 once a month, but not able to reproduce every time car is stopped... therefore can not be repeated upon inspection. Happens at the worst time, during traffic stops. --Complaint was made during oil change, but dealer found no problem. No warning lights prior to stall. Problem has happened and reoccured for almost two years.

The auto start/stop system on the Honda Pilot is failing at intersections causing the car to stall out and be stuck in traffic. Dealer and Honda does not have remedy for this issue. This is a known problem that is well documented by other owners. This is now happening about three times per week and I am worried that it will cause a major traffic accident and or death if I get stuck in the middle of an intersection.

When breaking at a stop. Entire car shuts off instead of just the engine. Turns off and have to restart car while in traffic. Has occurred 4-5 times so far.

I moved into the left lane to merge onto another road. I had to come to a stop because a car had was stopped ahead of me. After that car moved, I lifted my foot from the brake and pushed the gas to make my left hand turn. The car didn’t move. A light flashed on the car that said something like “to start engine push brake and push start” I looked down at the gear shifter and noticed it was on N. I tried to hit “drive.” The car flashed the sign again. I put the car in park. I tried to put the car back in drive. The car would not change gears. I put on my hazard lights, turned off the car, and restarted it. The car transitioned from park to drive. There have been many instances where I’m merging onto a roadway or slowing down to...

Issue: engine sometimes does not start after engine idle stop activates On several occasions while stopped at traffic lights the engine failed to start requiring the driver to turn the vehicle off then back on. This occurs after the engine idle stop actives. When the engine stops electrical components, such as the radio, momentarily lose power. The dealership was not able to reproduce the issue. Members of my household have encountered this issue several times a week over a 2 month period. This is a safety issue as the car does not reliably start in traffic.

The auto start and stop engine feature leaves the car stalled and unable to restart until multiple attempts. We have been stuck in the middle of a highway multiple times with hazards on trying to restart

When exiting the interstate and stopped at stop sign, vehicle shut off due to auto stop/start feature. When I released the break to go, the vehicle did not start and completely shut down. The vehicle had to be placed in park, break pressed and ignition button pressed again. It took a little bit but it did start again. After this incident, this has also happened about 10 more times stop lights around town. It has always started again but it takes a minute to restart and multiple steps are needed for it to be restarted. Traffic has been backed up while I attempt to restart the vehicle.

I own a 2017 Honda Pilot Touring addition and recently learned there is an investigation on the auto start/stop feature. We have experienced the vehicle stalling too many times to count. However, it does seem to be getting more frequent as the vehicle gets older. When the vehicle comes to a stop the feature will engage and two things may happen: 1. The vehicle will immediately die causing us to put the car in park and restart or 2. The vehicle will stall/die when in the movement of taking my foot off the brake and pressing the gas pedal. On some occasions we have had to try multiple times to restart the vehicle. The most memorable stalls happened during busy traffic and of course caused a panic as the time to restart feels like minutes when it’s really only seconds. When this happens it has caused us fear of being...

The Idle/Stop function stopped operating at a stop light. The car completely shut off. My wife pressed the brake and ignition but the car did not immediately restart. After a few long minutes, the function worked. This is the second incident with the Honda Pilot. In May 2022, the vehicle stopped at an intersection and cut off. I took it to the Honda Service and had diagnostics ran. I was charged for the test but the Service Department did not find anything wrong. They recommended a new battery which I purchased. This was in May 2022. There is definitely an issue. No use taking it back to the dealer, they don't know the source of the problem.

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...

While driving I first noticed the radio would shut off- almost like an electric surge (Spring 2021). I brought in to local dealer to assess. Dealer couldn't replicate so was dismissed. Car slipped into "sport" mode randomly (July 2021). Brought in to dealer and couldn't be replicated.Then the car would take longer to start at a stop light. Eventually, at times, the car would NOT START when the brake was released and gas paddle depressed (August 2021). There is no warning or indiction that this will happen. It is periodic, random and unpredictable. The stall out has happened on long and short rides. This has occurred at stop lights, stop and go traffic on a busy highway and entering traffic circles. I could have easily been rear-ended at any of these stalls. I am afraid when driving this car. The dashboard lights up with alerts and the car must be...

At least once a week the vehicle shuts off and don’t restart at stop light/ sign.

Keyless start system problem error message even after replacing key fob battery

When the car comes to a stop at a light or intersection, the auto-idle function of the engine engages (indicated on dashboard). When you lift your foot off the break, the radio shorts out, the dashboard flashes, and the engine struggles to restart. This happens regularly. I've even had my vehicle stall in the middle of the road after auto-idle has been engaged (see video). I've taken my vehicle to the Honda dealer several times to be serviced, but each time I'm told they are unable to re-produce the problem. Last time I was at the dealer, I shared this video with them, but they communicated the same message. They can't reproduce my issue and my vehicle is safe to continue driving. I feel strongly that this is a safety issue. If I'm stalled at a busy intersection and drivers behind me are not paying attention, it is likely I'll...

I come to a full stop at a red light at a busy intersection. The auto engine idle shut off engages. When traffic begins to move I lift my foot off the brake. Usually this restarts the car. However, the engine turns off as if it is in Accessory mode. I try to put the car in Park and Turn Off and Turn On, but it requires me waiting a minute or two before I can restart the car. This problem has happened many times and I have reported it to the Curry Honda service in Yorktown Heights, NY (10598) many times. The are aware of the problem and says that there is no fix.

The auto start\stop feature doesn't work and is extremely unsafe and dangerous. I will be sitting at a stop light and when the light turns green I take my foot off the break and the car will completely turn off and error messages will appear. Multiple times it has completely turned off the car and the car couldn't be restarted right away, leaving us stranded in the middle of the street trying to restart the car while cars are going by me. It takes at least a minute for the car to restart once it turns itself off. This has happened at least 10 times. We always turn the feature off when we drive now but sometimes we just forget because it's extremely inconvenient and difficult to remember that we have to turn off the feature every single time we start the car. When we took it to the dealership...

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.

The idle shut off feature has shut the car off and then not restarted when it was supposed to. This has happened in two intersections and a stoplight. When it doesn’t restart, I am unable to do anything, shift in to park or restart the car. It is extremely unsafe as it leaves you sitting in the middle of traffic or wherever it decides to leave you and you can’t do anything with the vehicle. There is no warning when it does it. I have not approached the dealer since there is a button to override the feature I figured they would not listen. However I think it is ridiculous that you have to push a button to make sure your vehicle doesn’t die on you while driving. I would like to see the auto idle feature removed from the vehicle.

There is a major and potentially dangerous issue with the idle stop/start feature. When the car is at a stop and the engine shuts off (gas saving feature) and sometimes the car will fail to start again, leaving me stranded in the middle of an intersection or whatever road I'm on. Sometimes all of the collision systems fail to start again (dash warning), sometimes it takes minutes to get it restarted which results in angry drivers behind me and the potential to create an accident. This issue began within a few months of buying the car. I had informed the original Honda dealership where I purchased the car but they failed to properly document the issue because there were no error codes populated by the on-board computer. After it happened dozens of times I took the vehicle to a different dealership and was able to demonstrate the problem directly to...

On multiple occasions with the auto engine restart engaged, the engine has shut off while stopped at a stoplight and then failed to restart the vehicle upon attempting to go. On some occasions, the power blips but the engine restarts. On other occasions, the power blips and the car stalls, leading to having to fully shut the car down and turn it back on, with a successful restart. On a few occasions, this has taken multiple tries leading to the vehicle sitting at a green traffic light for over 15-20 seconds while attempting to restart the engine. This is a safety issue as I am now scared to leave the auto-restart feature engaged for fear of being stuck at a green light and rear-ended. I have tried to turn the feature off, but there is no way to disable it permanently… instead, I have to remember to turn it off...

Hello, I was driving down the road and my collision mitigation light quickly flashed on and then went off with no objects in front of me or bad weather or rain. Also, my vehicle felt like it tapped the brakes and the steering wheel slightly jerked a little. It was maybe a half second long and then went back to normal. I kept driving and the vehicle did it once again and then 2 more times. The last time I was pulling up to a light when it did it. I should have pulled over first but I decided to turn the vehicle off and turn it back on to maybe reset the computer. Also, I know the car does this anyway when I have my auto start/stop button on. I usually turn it off when I drive. I've had the vehicle since 2018 with no issues before so I...

I own a 2017 Honda Pilot Elite, with 65000 miles, that was purchased new. The vehicle has repeatedly stalled at various point of operation. Upon stalling, every light appears to activate on the dashboard. The vehicle remains stalled until the computer "recycles." I can usually restart the vehicle within 2+ minutes. The dealer, located in Rancho Santa Margarita, California, has identified the vehicle’s stop-start as the problem. The dealer suggested to turn off the stop-start while driving the vehicle but that is problematic as this needs to be done each time the vehicle engine is turned off and then restarted. The dealer, upon inspection, found some errors in the ECU, but none that would create this problem. The dealer is unable to recreate the problem and admitted that many Honda Pilots have this issue. To possibly fix the problem, the dealer suggested a valve replacement at a cost of $1000+...

The auto start/stop is not reliable. I have had three incidents in the past 2 years where if I'm at a light and the car turns off due to the auto stop, it will not restart. I did take it to my dealer and they could not find anything wrong with the battery or any other issue. I have to manually turn the auto stop/start feature off every time I drive the car in fear I will be stranded in an intersection. Very frustrating. It has been an issue for 2.5 years out of almost 5 years of owning the car.
