When attempting to start the car's engine by pressing the start/stop button, it takes several times of pushing the button to start the engine and the dashboard displays a keyless start system error. There is a tech service bulletin for 2016 and 2017 models of the same car providing an extended warranty for customers to get free start/stop switch replacement. I took my car to a dealer and and they reproduced the problem. I was told it was not covered under the warranty. Why did Honda provide warranty and free replacement for previous model years but not for 2018 model that had the same problem? Please advise.

As of 11/21/23, our honda pilot has approx 75,000 miles, we purchased it new so we are the only owners. A few weeks ago, the vehicle while driving about 45 mph, completely shut off, all lights on the dash cam on and the transmission became disengaged. We were able to shut it off for a few minutes, and drive it about 1/2 mile to the local Acura dealership. The car did not operate normally though, it would only go about 20-30 mph, before the transmission disengaged for a few seconds, then re-engage and continue driving. Acura said it was a producing a bad cam-shaft sensor code, they reset it, but said if it happened again, they would need to open up the engine to inspect the cam-shaft. Two days later, the exact same thing happened, we returned it to the same Acura dealership, where they said the cam shaft, and abunch of other parts needed replacement, at a cost of about $2,500. We had no choice since the car was immobilized. Now, the week of 11/20/2023, a recall regarding the rod bearings was issues, which cause the exact same immobilization issues we experienced, which is very dangerous as a driver. Upon research online, the cam shaft sensor and faulty cam shaft is more common than I expected, and I believe should be investigated before someone is seriously injured. To add, our specific pilot is not showing the engine rod recall, but we have experienced issue with the vehicle in regards to the auto start/stop feature and the car not restarting, as well as cruise control issues where the car will go into neutral at 70+ mph when cruise control is activated. We will probably not have this vehicle much longer because of the issues we have had in the first 75K miles, and the continued safety issues that plague this model. More needs to be done for the safety of it's drivers and passengers.

The contact owns a 2018 Honda Pilot. The contact stated that while stopped, the Auto START/STOP activated, the vehicle shutoff but failed to promptly restart while depressing the accelerator pedal. 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. The failure mileage was approximately 90,000.

The wave radar came on during out travel. We traveled in south Dakota on through construction when the light came on. Now I went to the dealership to get an oil change and ask them about the error. I was informed the the wave radar part had been over worked and need to be replaced. Cost $1268.70. We never got in a collision. The part should not fail for being used causing the error message. I also belive it is a huge safety concern because I dont know if the collision system will work. The second issue we are having with the vehicle is that we turned it in for the recall for the idle stop function. It continues to turn off our vehicle at stoplights and on stops on s hill. I dont feel safe operating this vehicle with me and my family.

I previously reported issue 11360107 which Honda attributed to a bad battery cell and replaced the battery on this vehicle. I followed up with them that I consider auto-idle-stop functionality that doesn't restart despite the battery being capable of restarting to be a safety issue. I re-iterated to them that I "rebooted" the car by holding the car start button down until the Honda logo appeared in the driver display. The car then proceeded to start and I didn't have any issues with the battery being able to start the car before or after that. As stated in that issue, this happened on the access road of a major Texas Freeway while stopped at a stop light. Cars were flying by at 50 mph with my family in the car sitting at a green light. Honda has apparently issued a "fix" for this, but today I experienced a similar issue at the gas station. Today was different b/c my auto-idle-stop was disabled. My Honda dealership had disabled it the second to last time I brought it in for service, but didn't tell me. I had complained to my dealership about this issue in the past, but the feature had been disabled when I received it, without notating the change in any paperwork. I asked about it the last time I had my car at the dealership and they acknowledged that Honda was telling them to disable the auto-idle-stop on vehicles where the owner said something. Today, July 16th, 2023, I experienced the same behavior when I stopped for gas. The car would not restart, the starter would not attempt to star the car. I had driven about 60 miles in this 100 degree weather in Aransas, Texas. After filling up with gas my car wouldn't start, the electronics worked, the radio came on, but the car wouldn't start. I got out of the car while the electronics were on, went to talk to another person in the caravan. I came back and tried again and the car started. The battery was obviously capable of starting the car without jumping.

When the vehicle is turned off, the lights panel will flicker. You can hear the relays clicking behind the panel. The headlights will come on. The car alarm will go off at random. On average 7-10/per day. I-??ve taken the vehicle to the dealer and there appears to be a back order of the part needed to fix the issue.

Emissions light comes on due to a faulty Fuel Injector and Catalytic Converter. This continues to show up in multiple forums when it comes to this problem.

- Heartland, TX, USA

The car has an automatic engine shut off when the car comes to a complete stop (brake pushed fully). Over the course of a month, the car will stop and start correctly many times, however 5-7 times a month the engine will not come back on...the lights and radio will all be on and the engine will not come on. This requires me to put the car in park, turn the car completely off, restart the car all while the light is green and cars are behind ready to go. The battery is fine. There is an issue with the automatic system. Unfortunately Honda Dealership has not been helpful and is more interested in charging extra money. I have read this is a problem that needs to be addressed.

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.

- Lake Clarke Shores, FL, USA

The problem began in May this year and has gotten worse over time. The idle engine stop does not always work properly. After driving for 10-15 minutes in stop and go traffic, when the brake is released, a popping noise or click is heard and the electronics (radio, AC, etc.) go off momentarily. When the idle engine stop is working properly, there is no noise and the radio, etc. are not interrupted. After several additional miles of driving, the noise or click becomes louder and the engine will not restart. I have to put the car in park and restart the engine. This is a safety issue in that my vehicle blocks traffic and given the number of aggressive drivers today, I am concerned someone could react in an inappropriate manner. Now, whenever I begin to hear the noise, I am forced to manually turn off the idle-stop feature. Honda responded to my concern by saying they have no "open campaigns" on the issue and for meeting to see the dealer. In the past the dealer says they have never heard of this problem and said they could not do anything. I saw online there are multiple others with the same problem and the NHTSA has opened an investigation as of June 2022. I am very disappointed that Honda US does not seem to be addressing the problem so I am adding my complaint to the NHTSA investigation. I look forward to hearing what can be done to alleviate the problem. Thank you, Dan

When the idle stop feature is active the vehicle can stop, ceasing all functions, including steering and engine. The entire electrical system does not function, and the vehicle cannot be restarted. In order to restart the vehicle you are required to jumpstart the vehicle. This issue was not common during early ownership of vehicle, but has become more frequent with age. This is a safety issue as the vehicle can become inoperable in busy intersections.

When stopping at a traffic light the engine auto stop/start engages, but then the engine will not power back on when I release the brake. I have to completely restart the engine, causing a safety concern with other vehicles behind me. This has been ongoing for the last 6 months or so, and it seems to be getting worse. Sometimes the car will turn off mid intersection and we will be stuck there for 10-30 seconds while I try to get the car back on and going again. It is a very dangerous hazard and Honda denies there being an issue. After reading online it seems that many people are having a similar problem.

- Wellesley Hills, MA, USA

When stopping at a traffic light the engine auto stop/start engages, but then the engine will not power back on when I release the brake. I have to completely restart the engine, causing a safety concern with other vehicles behind me. This just started in December 2022 and seems to occur daily.

- Lincoln, CA, USA

Numerous restart issues when car in in idle mode stopped at a traffic light or stop sign. Car does not idle but completely powers off. I'm required to place car into "park", turn on power, shift to drive in order to accelerate

- St Augustine , FL, USA

On at least three occasions after being stopped at a light the engine suddenly died (not simply auto idle stop). After putting in park and shutting off ignition (button start) and waiting some time the vehicle could be restarted. Battery is good. Fuel is good. Injectors already replaced. Dangerous as vehicle may be unexpectedly on powered while in traffic

- Cincinnati, OH, USA

Car does not turn on after stopping at a red light with auto start/off on. Turns on after being jump started. Also windows automatically come down without pressing any buttons after opening or turning off car. Dealer reports no issues. Battery has been changed with no solution. Car is inoperable with concern for pedestrian safety and personal safety.

- Corona, NY, USA

I was stopped at a red light, the engine cycled down because of the environmentally friendly option. My foot was on the break. The transmission shifted to neutral and turned orange. I could not get it to shift back to Drive. I had to turn the car off and restart it. At that point I was able to put it in drive and move the car. This was very dangerous because I was on a busy highway and could have been rear ended by a driver not noticing the car was stopped and off.

Auto engine on/off option- when on and at a stop the whole vehicle shuts down I have to hold brakes down press engine on/off to correctly shut it down the start the vehicle

- Arnaudville, LA, USA

The vehicle routinely shuts off at intersections and is unable to restart. This often causes traffic to back up behind the vehicle and vehicles around us having to make sudden stops. This occurs during normal driving conditions about 3 times/month. It seems to be attributed to the automatic shut-off feature but does not restart as it should when operating properly.

- Sandy Springs, GA, USA

On multiple occasions the idle stop feature will engage and upon re-engage it will stall my vehicle. When I place the vehicle in park, press the brake and press the ignition start, nothing happens. Upon multiple attempts to restart the car it will either do nothing or making a chug without restarting. Continuing my attempts to restart the vehicle it will finally restart. During these times I will be stalled at a stop sign or traffic light with impatient drivers going around me. All the dashboard lights come on. I have taken it to the dealership, they stated they couldn-€™t duplicate the problem. This is unsafe for motorists or pedestrians. If this happens while I'm in an intersection or other location with moving traffic it could be very unsafe for myself, other motorists and/or pedestrians.
