2017 HONDA PILOT Electrical System Problems

I had been driving for over an hour at 70 when I crossed into Pennsylvania and encountered crawl speed traffic. I exited the highway at exit 1. At the top of the ramp there is a traffic signal. I stopped at the red and the vehicle shut down. The light turned to green and the vehicle immediately in front of me proceeded into the intersection. I removed my foot from the brake and attempted to go. The engine auto stop-start kicked the engine but then the engine immediately cut off and the chimes went off. The car behind be stopped abruptly to avoid contact. Attempting to understand what occurred i looked at screen. The screen indicated to shift the vehicle into park. I did. The vehicle did nothing. Since there is no way to to start the engine without it, I was forced to turn the vehicle off using the...

While Stopped at a stoplight the Auto Start/Stop feature stalled the engine. This has happened to us multiple times.

A few months ago, car started alarming randomly. Upon entering vehicle all lights on dashboard were going on and off, screen was going through each system followed by "problem" and repeated clicking heard in steering column and captured on video for 1 minute. This continued for several days but car drove okay. Alarming bouts came and went for a few days. I researched and found that it was probably the Keyless Access Control Unit based on other owners of similar years/models. Took to dealer and showed my video. After inspecting they came back saying that they called Honda and it was a different part (unknown) but described as more of the control computer for the car. They placed the part on order, but said that another customer had the part on order for over 4 months at that time with no ETA. Six weeks later, without an incident, the car...

When the vehicle has been shut off, there is an electrical system problem that attempts to re-start the vehicle. the alarm goes off, headlights turn on, the dashboard lights up. This cycles over and over unless you open the hood or a door to "fool" the system. If you don't do this, then often the headlights and dash light will remain on overnight and the battery is dead the next morning. This prblem has been occurring for two years, but the dealr has not diagnosed it becasue it is intermittand and doesn't throw a code.

Beginning in February 2023, around 2AM, my car alarm would sound. Upon inspection, the vehicle dashboard was lit up and clicking relay sounds could be heard from the dashboard. In essence, the car was trying to "start" itself. When the attempted start reached a certain level, the car would recognize the absence of a key fob, and thus, the alarm would sound. To remedy this, I had to leave my key fob in the car - which did not prevent the attempted starts, but at least prevented the alarm from sounding. In the morning the battery was dead from the headlights and interior lights flashing all night. Additionally this was a safety issue as I had to leave keys in an unlocked car. The dealership cannot reproduce the problem, as it happens in the middle of the night (particularly when it is raining or very humid outside). I have found...

The contact owns a 2017 Honda Pilot. The contact stated while at a complete stop, the vehicle stalled due to a defect with the Auto STOP/START feature. Several unknown warning lights were illuminated during the failure. The contact was able to restart the vehicle after several attempts; however, the failure persisted. The vehicle was taken to the dealer on several occasions where a software update was performed, the starter motor, starter switch, fuel injector and valve adjuster were all replaced; however, the failure persisted and worsened over time. The manufacturer was contacted and filed a complaint. The vehicle was not repaired. The failure mileage was approximately 10,000.

Vehicle sitting in driveway on hot day started alarm beeping, headlights and tail lights remained on and dashboard warning lights going on and off as if a poltergeist possesed. Car could not be locked. Depleted car battery resulting in new battery being required. New battery did not resolve problem Car drives without problems except some dashboard functions no longer visible Dealer states Smart Access Control Unit, part #38320-TG7-A32, is needed. Part is on backorder from Honda with changing dates of availability. Car is not safe to drive with children and subject to theft since it cannot be locked.

This vehicle keeps having a "Emissions System Problem" Then other times says "Transmission Temperature Too Hot" I bought and get this serviced at my local dealer. They don't know what the problem is and it goes away after I see them for a couple weeks but the problems come back. They say no problem. It's unnerving to drive a car with theses messages and I drive long distances.

Alarm spontaneously went off while in garage & several indicator lights lit up and repetitive clicking sounds heard. Honda dealership Johnson City, TN diagnosed problem as a faulty body control unit module. I was told I could drive the vehicle and afterward unhook the battery cable to keep the alarm from going off & draining the battery. I followed instructions but then it would not start and was then told the body control unit module is at fault. My understanding is that some features of safety are compromised with body control unit module malfunction so perhaps I should not have been given this advice?? When we first got vehicle, 2017 awd honda pilot w RES - the NAV system did not work. Supposedly they replaced it - still does not work. The RES quit approx 2019 - still not work. My wife was told it would cost 2-3,000$ to fix...

Emission system problem , transmission system problem. Car frequently stops with these error messages and it stopped the acceleration during driving on a freeway. It could have caused a major accident if I had not pulled over safely.

On March 18th, 2023 at 6:30 PM I parked my car and waited for the curbside pick up at a cafe with my 3 girls 6 (my niece) 7, (daughter), and 11 (daughter) years old. The car started blinking all the lights started accelerating by themselves and turned off immediately. while I tried to turn it on it never started instead it blinked and displayed many messages, including transmission system problem, emission system problem, etc. I thought the battery died and called my husband to jump-start the car and it took 30 minutes to get driving with all these scary movements. my kids were traumatized by the experience and I thought thank god they were safe and the problem is solved. After almost a week once again on March 27th at I'm driving the kids to Karate and driving back at 5:45 PM all of sudden it started blinking, shanking,...

The autostop feature on the car fails to restart the engine. The car completely shuts down and all electrical is dead. This has happened multiple times over the course of many years. Often is takes multiple attempts to restart the vehicle while sitting in dangerous traffic situations (e.g. highway, nighttime with no lights). This is a significant safety issue. Honda has failed to fix the problem despite a new ignition switch and new battery. They don't seem to know how to fix it.

Went out to garage and started noticing headlights and running board lights were on, so assumed another household member had opened door to put something in the car which is not common. After this started occurring more often, asked and no one fessed up so started paying closer attention and even opening garage door just to check. After that, started noticing clicking sounds under the hood. Googling, saw online that others had similar issues. One day went to start car to head out and the car was dead. Called dealer and they said I must have left the car in accessory mode, but I wasn't so sure. AAA jumped the car with much effort. Next morning, car would not start again. This time, I remembered I had one of those jumper boxes and was able to start it, maybe because it was just one day difference. I know I was...

This appears to be a known problem with the Honda Pilot with the car auto start/stop feature. The power/engine cuts on and off when trying to start back up. The dealer replaced the battery but after around 6 months it has started again. Before the battery replacement, we had the issue happen on the freeway while driving. So, it wasn't just after the autostop but it happens more prevalently then. It happened at least 2 to 3 times on the freeway. After reading that some vehicles don't start back up, I am concerned that if this cuts out on the freeway and doesn't start back up, it could cause an accident on the freeway at high speeds. I urge you to push Honda to recall the vehicle to fix this issue before someone get hurt. The dealer tech doesn't know what to do to fix the problem. And, doesn't appear...

The contact owns a 2017 Honda Pilot. The contact stated while driving approximately 15 MPH and decelerating, the fuel saving feature malfunctioned, causing the vehicle to hesitate and almost stall. The contact was able to drive the vehicle off the road to turn off and restart the vehicle. After restarting the vehicle, the transmission erroneously shifted to neutral and failed to drive. The cause of the failure was not yet determined. The manufacturer and local dealer were notified of the failure. The failure mileage was 24,000.

The contact owns a 2017 Honda Pilot. The contact stated while making a stop, the vehicle stalled without warning. The contact was able to restart the vehicle. The dealer was contacted, and the dealer confirmed being aware of the failure; however, there was no fix for the failure. The manufacturer was not contacted. The failure mileage was 40,000.

Idlestop issues

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 Dealshp also claimed they were unaware of any issues with the Auto Start/Stop feature. /////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// Scott Robinson Honda...

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.

The alarm has gone off 30 times from 7am this morning to 2pm. I also have a picture of the dashboard lights. About a month ago I took it to the Honda Dealership and they charged me for a bunch of other things and gave it back for it to do it again the same day. Honda said it's a control unit they need to replace but I have to pay?

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.

Several times while at a full stop, the idle stop feature has failed when I have taken my foot off the brake and tried to accelerate. The error message tells me to put vehicle in park then press start. That does not immediately work. So far, I have gotten the vehicle to start within 1-2 minutes but this is a safety problem for me and other drivers on the road. I have not taken this to Honda but will be doing that in the next few days.

My Pilot is suffering the auto stop/start fault that many others have reported online. The vehicle will sometimes fail to restart from the stopped state, forcing us to manually turn off, and restart the engine. As of this morning, the vehicle permanently reports an "Auto Engine Idle Stop System Problem" error.

Keyless Start System Problem indicator illuminated in driver information display. Error notification is displayed intermittently. Stays on for several drive cycles and then goes off for a bit only to come back on again. So far the car seems to start ok, not sure if this issue may eventually cause car to no longer start. This issues has been going on for a few months and will stay illuminated for weeks then suddenly turn off. Scheduled an appointment with local Honda dealership but the indicator was not showing the day of the appointment so we cancelled as do not want to pay for the repair. This is a Honda issue and they should repair regardless of the indicator being illuminated or not.

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...

Keyless Start System Problem indicator illuminated in driver information display. Error notification is displayed intermittently. Stays on for several drive cycles and then goes off for a bit only to come back on again. So far the car seems to start ok, not sure if this issue may eventually cause car to no longer start.

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-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.

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.

Auto engine start/stop has failed multiple times causing dangerous conditions in traffic. Engine will not restart for minutes after cutting off due to start/stop component.

Car fails to restart when the engine auto shut off engages. The engine will attempt to restart, but then nothing happens. The car is essentially stalled in traffic. This has happened three times. The car has to be put in park and fully shut off before it will restart using the car’s on/off button. One time it took a few minutes before the car would restart. This happened even after having the battery replaced. I informed the dealer about the problem, and the dealer acknowledged that there is some sort of problem with the auto shut off feature.

Car alarm keeps going off randomly and the electronic dashboard flickers repeatedly while the car is parked. I recently left the car at a parking garage and apparently the alarm was triggered and ran all day - I came back to the car that evening and there was clicking sound coming from the engine (not turned on, of course). The battery was drained and when I got a jump start, the alarm went off and the dashboard went crazy again. I wonder what would might happen when the car is being driven. There's clearly something wrong with the electronics. The dealer said I needed a new body control module (BCM), but the part is hard to come by apparently. Having done some research on the the issue, this appears to be a common problem with Honda Pilots. My car only has 50k miles on it and seems out of character...

When at a red light the engine turns off when you press the brake. When you life you foot it should restart automatically. Multiple times my car has no restarted. It sends me a message to put the car in park, press the brake again, and restart with the push button. But it did not work immediately. I had to do the process 5-15 times before it restarted. This is a safety issue because I’m in a stalled car at a red light with traffic trying to get around my car or worse cars coming at a regular speed who don’t see I’m stopped. After researching I have seen that this issue has happened to other owners as well. I called my local dealership who said to bring it in so they could inspect it - which I have not done so yet. Just today there was a brief flash...

Our 2017 Honda Pilot is having issues with the idle stop feature at a stop light or other standard stops. The engine completely shuts off and all electronics also shut off. It then needs to be placed in park and restarted. However, it sometimes takes multiple attempts to restart the engine. We are now having trouble with it even starting when the engine has been off. All the dashboard lights come on and it sometimes takes several attempts to start the engine. This issue is very unsafe when traveling and having your engine completely shut off while in traffic and could easily lead to a traffic accident. We have spoken to our local Honda dealer several times about this issue and they have said that Honda knows about this issue but does not have any solutions for the problem. Something needs to be done about this before a serious accident...

While the vehicle was stop, the auto shut off went off, and upon moving the foot from brake and depress accelerator, the Honda Pilot 2017 turned off and restarted requiring driver to depress Engine Start again.

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 has happened infrequently in the past but is now occurring more often, multiple times a month.

1. The automatic start/stop feature sometimes fails to restart the vehicle 2. On a few occasions now I have been stranded at a stoplight trying to restart the vehicle with people trying to navigate around me. 3. I have not have it inspected by the dealer or mechanic yet. In my own research of the issue I found the there are a number of complaints about the same issue in the range of model years that includes my 2017 Honda Pilot 4. There were no lamps or warnings prior to the issue. When I take my foot off the brake the engine is supposed to restart but didn't. I had to completely power off the vehicle and open the door (so that all accessories like the radio were also powered off) and restart the car. But it took multiple tries. When I pressed the starter button the accessories would come...

After stopping and the auto start-stop system is utilized to turn off the engine, the engine does not restart on its own when releasing the brake pedal. The vehicle must be shifted to park, turned off, and restarted before you can begin driving again. This has happened many times and poses a major safety risk since it happens predominantly at stop lights.

Numerous times the auto stop/start feature has failed to work. When the car tries to start back after the stop/start feature has been engaged, it does not start and will completely turn the car off. All the electronics will flash off and back on. When this happens the car has to be returned to park and can take several minutes to start back leaving the vehicle stranded in the intersection. I have complained to the dealership but they say there isn’t a problem and to just turn the feature off. In order to do that a button has to be pushed every time the car is started.

For years the stop and auto-start feature will not restart automatically. Sometimes the entire vehicle itself will shut down, lose, power, then restart by itself. It is more frequent now. Last week while on the freeway, the car shut down and failed to restart altogether. The engine did not respond. I had to put it in neutral and restart the car. I had to attempt to restart it a couple of times before it finally turned on again.

When stopped, the engine idles off but when I go to accelerate, the engine shuts off. This is becoming a safety issue as the last two times were on a highway although it is really always a safety issue. Last year the dealer had me get a new battery. While that worked for a bit, the issue is back and worse than ever.

The auto stop/start feature is defective. It turns off the engine when stopped at red lights, but many times the engine then fails to start again when the gas pedal is pressed when the light is green, and the car stalls. This has left us stalled in intersections many times, and sometime it takes 10-15 minutes before the car starts again. We even had to call for a tow once. This problem has been ongoing for a few years and I have communicated it to my Honda dealership many times, and have brought it in multiple times, and they have failed to rectify the issue.

While a stop light, the Idle Stop feature engaged as normal, however when the brake was released the engine failed to restart. This is not the first time this has happened, but this time following the instructions on display, place vehicle in park and press the Start/Stop button, didn't work. It was at night and I figured I would turn off the lights and radio to help. It took 4 or 5 attempts to get the vehicle to restart. This happens more frequently when idle stop is engaged short order, such as in a long line waiting for a left turn.

On multiple occasions now my Pilot has completely shut down while the auto-idle is on and I have been unable to restart it quickly. My young children and I have been stuck in traffic multiple times unable to move or get out of the way of oncoming traffic due to this and most recently on 9/16/22 I was almost hit due to be unable to restart my vehicle. I typically keep the auto-idle off for this reason but if I forget to turn it off, it happens again. I purchased my car on 7/06/22 and this has happened 3 times (which is a very high percentage of the time the auto-idle is accidently left on). I have tried to take it into be serviced but it does not happen every time so they have been unable to assist. There are no lights on, messages or any indication when this happens,...

The car sometimes fails to restart on its own from a complete stop at a traffic light or stop sign with the Auto Start/Stop function engaged. Furthermore, on two recent occasions the car would not start at all after it was turned off to get gas. One of those times it sat for 40 minutes at the gas pump while waiting for a jump start (it eventually started on its own), and the other it had to be towed to the dealer. After the first incident, we were told there was nothing wrong with the battery and a month later, when the car had to be towed, we were told the battery was completely dead. The concern with the start/stop trouble has been reported to the dealer and we were told there was nothing they could see. There have been no warning lights, lamps or messages. The start/stop problem began...

The auto-idle system causes the car to stall quite often and poses a major safety hazard. We bought the car brand-new in May 2018. The problem started happening approximately 2 years after buying the car. The car fails to restart when you lift the foot off the break and instead, stalls the car. My husband and I have had the car stall at red lights, at stop signs, and recently while we were in the left lane of a major highway in traffic. Just this past weekend, it stalled on me twice in less than 24 hours. It takes quite a bit of time to restart because you have to put the car in park and make sure it is completely shut down before trying to start it again, while also trying to remember to put on hazard lights. I did bring it to Lia Honda in Albany NY on...

The idle stop feature not working properly. Many times the engine will not restart after releasing the brake and pressing the accelerator. This has left me stranded in busy traffic situations including intersections. This is very dangerous and a hazard for me and my family.
