My 2017 Honda Pilot does not want to start after the auto idle comes on. For example. When my Pilot comes to a stop and the auto idle system shut the engine off. The vehicle does not want to start when I take my foot off the brake. I thought it may have been my battery, it the problem still happened after I got a new one.

When at a stoplight, auto idle causes car to completely stall and shut down and won-??t restart unless car turned completely off and try to restart again. This has caused me to be placed in some dangerous situations where I have almost been rear ended from behind. Dealership says that it-??s the battery but from hearing from multiple people, this has not fixed the problem. It seems like it-??s something electrical with auto idle stop feature.

Many times over the past few years, my car has stalled out at a light or stop sign when the auto start-stop has been engaged. I noticed this happens more in the summer than winter. I have to disengage this function when driving, however, with no permanent way to shut off this feature, I often forget to shut it off every time I start the car. As a result, I frequently have to deal with the stalling. I have always been able to restart the car after a minute or so, but it's obviously a safety issue with cars stuck behind me. No warning lights come on before this happens, and I have no taken the car to a dealer or repair shop.

Auto start stop - car turns off and will not restart via auto start/stop system at red lights and stop signs. This is extremely dangerous in a heavy traffic situation. The system, if doesn-??t completely shut down is very delayed in responding to turn back on. I-??ve had this issue since I purchased the car. Dealership had no idea how to fix. They replaced the fuel injectors, thinking it would solve issue, which didn-??t help. I still own this car. 75,000 miles and this still happens.

The car auto stop/start feature is failing to restart the engine when coming to a complete stop, sometimes while in a turn lane turning left with oncoming traffic.

- Kirkwood, MO, USA

Auto start/stop has caused the engine to shut off multiple times. One particular incident occurred at a stop light and only turned back on after several attempts using the ignition button.

- Renton, WA, USA

Auto on/off issue. Vehicle did not restart after auto shut off. Luckily not in a place where it caused a traffic problem. After a minute or so of being off the vehicle being completely off it started up again. After it sputtered a few more occasions, I have been turning off the feature manually each time I start the car now. Honda doesn-??t allow you to permanently turn it off. It has to be done each time.

On numerous occasions when engine has automatically stopped, it has failed to restart to allow continued driving.

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.

- Crestwood, KY, USA

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.

- Cable, OH, USA

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.

- Wilmington, DE, USA

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.
