Problem: Malfunction of the auto engine idle feature. Multiple (five to ten) occurrences have been observed in this vehicle since 2021. When gas pedal was pressed to start the car moving forward after idling for traffic conditons, instead of driving forward, the car automatically engaged neutral gear. In order to place the car in drive gear, the driver had to power off the car and then power back on. This problem was observed while traveling in stop-and-go interstate traffic and also while stopped at stop signs. This is a safety issue because restarting the car immobilized it for about 20 seconds of time each incident, while in traffic that was trying to move at posted speeds. Because this has been an intermittent problem so far, it was unable to be replicated by the dealer-??s service technicians. There have been no indications of any problem prior to each stalling incident.

Multiple times the vehicle has shutoff when the it has reached a complete stop at a traffic light and has not restarted on its own. Took it to dealer but they could not recreate it supposedly. In addition fuel pump issues and the Honda dealer is not able to obtain parts to the fix the vehicle. Feels like a lemon vehicle.

Engine fails to start when idle stop is active. The June 2018 date was the first incident. There has been multiple incidents since.

The engine won-??t restart on its own from a complete stop, have to disable the auto engine shutdown due to concerns of car not re-starting.

- Santee, CA, USA

The automatic start/stop sometimes fails to restart and car stalls. The car must be shut off and turned back on. At other times, the engine shuts down immediately upon stopping, such as at a 4 way stop or in traffic. I must pump the breaks to restart. These are intermittent problems that sometimes go away on their own and it has not been able to be replicated when in the shop. No warnings or engine lights appear as a result of this problem. Because it is intermittent and can happen in traffic, it is dangerous. This problem has been recurring for months.

I have taken my car 5 times to the dealership due to it stalling at red lights or when stopped. This happens with the idle engine is engaged. It has almost caused wrecks due to shutting off and not turning back on. In addition, we are now having to replace the keyless access control system due to electrical issues that caused a severe crackling, alarm sounding, immobilizer activated. the only way the car wouldnt alarm was if it is unlocked.

When parked, the car begins to try to turn on. The interior lights flash, systems fire and the battery drains. Twice I was left stranded having to rely on tow trucks, replacing batteries that were still functional and running car continuously in order to not drain it since it is my only car and I needed reliable vehicle to get to my kids. I could have been stranded in unsafe areas, thus impacting the safety of myself and family. There was no warnings before this happened the first time. Then, after changing the battery, it went another week without issue and then randomly happened again, without warning or indicators. It was looked at by 2 mechanics, the first (Christian brothers automotive) could not find a problem. The second (Honda dealership) diagnosed it as -??body control module failure-code b12d3-??. They were not able to fix my car after diagnosing the problem today because they didn-??t have the part in stock. So, I am now having to disconnect my battery every time I park to prevent it from draining the battery and honking. As a single mom, with only one vehicle, this will be a long wait until the part arrives and can be fixed. On top of the exorbitant wait, the repair quote is $861.63 to correct. This is a manufacturing malfunction for which I do not believe should be my financially responsibility. Honda cars have had recalls of the BCM modules starting with the 2018 models. It is not a huge stretch to assume the 2017 pilot BCM was flawed as well. I hope this is made right, a recall issued and my repairs expedited and paid for by Honda.

The auto Start-Stop function is not working properly. In several occasions when the engine stops at a red light the engine will not start again. This has caused many dangerous situations as we got stuck in the middle of an intersection. The dealer has not been able to identify the problem. Also linked to this electrical problem is at time all kids of electrical warning messages appear in the cluster. I expect this to be an electrical/battery related problem.

For the past few months, I have been having issues with my vehicle stalling. This issue occurs while stopped at red lights, stop signs, and while sitting in stop and go traffic. My vehicle is equipped with the Auto Start/Stop feature, and while stopped at a stop sign for instance, the vehicle will auto stop but fail to auto start when taking my foot off the brake and hitting the gas. This has happened on numerous occasions, putting those in the vehicle and those in other vehicles around my vehicle at risk. I brought my vehicle to my local dealership, at which point they checked it and found nothing wrong with the vehicle. They also stated that they, and the vehicle manufacturer were aware of the issue, but have no solution for it. The first time I brought the vehicle in, the dealer told me that a possible fix was an update to the system, however I would have to pay for the update. After the service adviser spoke with the service manager a few times, the dealership paid for the $220 update. The vehicle has since continued to stall, the only thing that seems to assist is to turn off the Auto Start/Stop feature every time the vehicle is turned on. Last Thursday, the vehicle stalled again on my wife with our son in the vehicle at a t-intersection. The vehicle failed to start for approximately 10-15 minutes. I contacted my dealer again and was advised to bring my vehicle in. I brought it in and was told that I could have a rental car, but that I would need to approve paying a $160 diagnostic fee. They were unsure of a permanent solution for the problem.

Our 2017 pilot tries to turn on by itself, with the electronics in the dashboard starting and engine compartment relays firing, along with the exterior lights turning on without any driver being present or attempting to start the car. It happens even without the keys being present. As a result, the battery drains while the car is parked. We took our car to the dealership where we bought it and they confirmed the issue and stated we needed to replace our keyless access/TPMS unit to start and that we may need to a new start/stop switch. It cost $190.83 with tax to access. The car is serviced at Klein Honda in Everett, WA. The R/O number for the service visit is 652453/1. Instances of other Honda owners experiencing similar car issues can be found here: https://www.piloteers.org/threads/control-unit-problems.168522/ I noted that the 2016-2017 honda pilots have a recall/service bulletin for the start/stop switch (Honda Service Bulletin 20-117) and was told by the dealership my car is not included. I find that very disappointing since I own a 2017 honda pilot. I was quoted a repair cost of $967.36 + tax. This did not include the cost of the part (part number 38320-TG7-A32) costing $469.36 with tax. Therefore the total cost of the repair is greater than $1500. I ordered the part on March 16, 2022 and it is on back-order with no expected arrival date. I cannot currently drive my car because the battery is constantly being drained when the car is off due to this error. Our low-mileage 2017 Pilot (delivered on 5/31/17) should not have the failure(s) noted above. I am not aware of a greater recall that addresses the failure(s) and was told that our car is outside of the manufacturers warranty that could cover this since it is not part of the powertrain.

Vehicle randomly does not automatically restart after the auto engine idle stop engages when in stop-and-go traffic or when stopped at an intersection, resulting in a stalled vehicle in the middle of traffic. Takes multiple attempts of hitting the start-stop button to restart the vehicle. Have taken the vehicle to the dealer numerous times and each time told they can't figure out what causes the problem, but they replaced the battery at a cost of $500...didn't fix the problem. No warning indicators before the vehicle stalls, the engine simply doesn't start again after the brake is released, which should disengage the auto idle.

Driving into work, busy road/heavy traffic, the auto-stop engine function engaged. It shut down the entire car and would not restart after releasing the brake. I had to put on flasher, and then restart the car as normal. Component failure: Auto-Stop Safety issue: Could be rear-ended, or worse if this happened in an intersection Vehicle will be inspected tomorrow by Honda. This problem has occurred before.

- Marietta, GA, USA

The contact owns a 2017 Honda Pilot. The contact stated that while driving at an undisclosed speed, the emission system, transmission, and Collision Mitigation Braking System warning lights were illuminated. The vehicle then lost motive power. The contact was able to pull over and park the vehicle. The vehicle was towed to the dealer and diagnosed with an oil rocker arm error code within the VTEC system. The dealer informed the contact that a non-OEM oil filter was used, which might have caused the failure. The dealer performed an oil change; however, the failure recurred. The vehicle was towed back to the dealer and diagnosed with oil rocker arm spool valve failure. The dealer informed the contact that the oil rocker arm spool valve needed to be replaced. The vehicle was not repaired and remained at the dealer. The manufacturer was made aware of the failure but informed the contact that the vehicle was not covered under warranty. The failure mileage was approximately 61,000. The VIN was unavailable.

This is a random issue that has now happened 3 times in the past couple of months. When the auto idle system is engaged and going to restart, the car stalls. You are stuck in an intersection, at a light, etc. You then have to figure out how to restart the car, which isn't easy, the start button has to be pushed multiple times as you are trying not to panic.

Traveling about 70 mph on the interstate using cruise control. I don-??t think there was a change in steepness/grade, but if there was it was mild. Suddenly, the rpm-??s were erratic and the engine and gears seemed out of sync. Pressing the gas pedal didn-??t seem to effectively accelerate the vehicle. I don-??t believe the brakes were affected. The -??D-?? for drive indicator kept blinking on and off. Multiple warning lights on the dash display: transmission system problem, all wheel drive problem, and interestingly, blind spot monitor problem. The last indicator to show was emissions system problem, and this indicator remained on the screen. I exited the interstate. Shifted to reverse, then parked the car and turned engine off. After a few moments, I restarted the engine and the only anomaly I observed was the warning indicator light on the dash read: emissions system problem. There was roughly 1/4 to 1/2 tank of gasoline remaining at the time of incidence. I continued to drive approximately 350 miles more to my destination, without using cruise control and without further or other issues. I made a couple stops to add gas and both times the engine was turned off then back on again without issue. The following day, after restarting the engine, the -??emissions system problem-?? warning indicator light was no longer showing on the display. I have yet to encounter the problem thus far, but I haven-??t used the cruise control since nor have I driven at interstate speeds for any considerable length of time. I haven-??t yet taken the vehicle to the dealer for inspection. But will do so.

On my way to work yesterday, I took my exit and stopped at the light where the idle engine function enabled and then my car completely shut off on its own. It took multiple tries to restart the car. Meanwhile, the light turned green, multiple cars were honking at me, and could have most certainly rear ended me. If it was the next street over, it would have been quite a dangerous situation as it is a super busy area. Upon taking it to the dealership today, they cannot figure out the issue.

Auto engine stop does not restart when releasing brake pedal. This causes safety issues when stopped at lights as it takes time for the car to go into park in order to be manually started. Only solution is to turn off Auto engine stop every time car is started so that it won't automatically turn off when brake pedal is fully pressed. Honda needs to recall and provide a solution that permanently disables the auto engine stop.

- Pepperell, MA, USA

On multiple occasions over several years the car will shut completely down when accelerating from a stop light or stop sign. The car has to be restarted and it is not safe. Most recently it happened twice in 1 week and the car will not restart immediately because you have to get it into park. It's very dangerous and the dealer is useless as they "can't get the issue to duplicate"

- Pineville, LA, USA

So when I-??m at a red light that turns green, when I attempt to go by lifting the brake my engine quits, that i have to wait a few and restart the whole thing,
