2020 Honda Pilot: won't start

Filed Jul 14, 2026 · Driver assistance · TX

Lots of crackling noises via the audio system. Display reboots itself many times before it finally went BLANK. Radio / DVD DEAD. Blind Spot warnings DEAD. Back up camera DEAD. Navigation DEAD. Eventually the battery goes DEAD and the car will not start. Got Stranded a few times. Changed the battery. But hopeless and reliability is DEAD. Definitely disappointed with HONDA.

The problem on our Honda Pilot is related to the starter. We have had four instances now where the auto start/stop function has failed to restart the car after sitting at a stop light. This has happened at very busy intersections resulting in difficulty restarting the car and the car temporarily disabling the auto start/stop functions. I just had this happen for the fourth time on 7/9/26 at approximatlely 6:00 PM. I am planning on taking it into the dealership to have it looked at since it has happened multiple times. I also see on the Internet that other owners are having this issue and the federal safety agency is looking into it. I feel this is a significant safety issues since this happens in traffic and could result in people being rear-ended when their car won't start. This problem started for me about two months ago but I thought it was just a fluke but apparently it is not. The battery and electrical system has been checked and are working properly.

The auto stop/start idle function does not re-engage after stopping the engine. This has happened at least 4 times in the last 3weeks with my vehicle. When stopped in traffic or at a light and stop sign the engine idle engages and stops running the engine, when releasing the brake pedal the engine does not turn on as it should and the car stalls. This requires the operator to engage hazard lights, shift into park and repeatedly try the push start button to turn on the vehicle to proceed. The passenger safety of myself and children are of concern. While having to wait on a car function, that is the core operation of the vehicle, it is dangerous to shut off a vehicle while in operation. Having other vehicles honking and trying to pass or even stopping at a highway entrance ramp then trying to engage the car to meet highway speeds is a dangerous time for an engine to stall and not re-engage. Yes, the issue has been reproduced and a dealer has already addressed the issue with a software update. This update has not resolved the issue. There are no current recalls on my vehicle. There are no warning signs or messages or the ability to turn off the function permanently. In addition, there a times during the operation of the vehicle where the engine stop/start function works after many stops but then randomly does not start. It is an inconsistent feature.

What component or system failed or malfunctioned, and is it available for inspection upon request? When calling the dealer they believe it is the “Smart Control unit.” How was your safety or the safety of others put at risk? My vehicle will not start most of the time…leaving me stranded when I have to go anywhere and I have to get out to take the battery terminal off and back on just to try to reset it long enough for it to try to start. Has the problem been reproduced or confirmed by a dealer or independent service center? No, from my understanding of reading other people having the same problem Honda knows it is a common issue and has not done anything about it. The dealer wants paid to do an inspection. I do not have the money they are asking for. I know inspections aren’t very expensive but most people (myself included) can’t afford even a simple inspection. Just to pay for the car takes all I have. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? At first I noticed my car alarm would go off randomly and originally thought my doors weren’t being shut all the way however after making sure all doors were in fact shut it still went off. I was at work that night and had to keep going out to turn my alarm off…the next morning I go in to start my car and leave and it had trouble starting saying “keyless start system problem” after finally getting it started I drove to the gas station to get gas and turned off the engine as I was walking away I heard cracking noises and my car making the ding noise it makes when you turn it on ACC mode. When I came back to the car all the lights on the dash, radio screen, headlights, tail lights, and mirror lights (the ones that light up when a car is close) were flashing like crazy and still heard the crackling noise.

While stopped at a red traffic light after taking a freeway exit with one foot on the brake, my 2020 Honda Pilot engaged in auto stop (auto idle stop). When the traffic light turned green, I took my foot off of the brake, the vehicle attempted to start but stalled with the electrical components still on (dashboard indicators and ventilation still on). I stepped on the brake and attempted to put the vehicle in park, but noticed the vehicle would not shift out of neutral. I pressed the start/stop button (ignition) and the dashboard indicators flashed but the engine did not start until the second attempt. Somewhere in between, I pressed the emergency lights to indicate to drivers behind me of an issue. About 15-20 seconds had lapsed during my troubleshooting attempt. Prior to this event, there were at least 8 individual events where when the auto start/stop was engaged and disengaged, the dashboard would flash warning signals for a fraction of a second with an audible warning sound. Dashboard warnings flashed on and off too quickly to clearly see what was being displayed. A short delay in restarting the vehicle from idle stop would occur, about 1-2 seconds but the car would then proceed and run as usual.

On four (4) separate incidents, my car has either abruptly stopped running (waiting at a stoplight) or not been able to start. When I push the Engine Start/ Stop button to restart the car, it does not start and several random warning and dashboard lights flash on and off like crazy. These incidents occurred twice before the recall was fixed and twice AFTER the recall was (supposedly) fixed. Please help as I don’t want to be stranded AGAIN! This car is only a few years old. Thank you

Numerous times while stopped at a red light/stop sign/traffic, the auto idle stop feature will kick in, but then the car will not immediately restart. Most times if the car is then turned all the way off and put in park it will restart. Now two different times, it would not start back up at all causing to car to be stuck in the middle of the road and requiring it to be towed. Prior to the incident occurring there were no warning lights or error messages.

The Auto Idle Stop system was engaged at a red light after exiting an expressway. When the light turned green, and I removed my foot from the brake, the transmission moved to neutral, and the engine would not start up again. I was unsuccessful in getting the car to start again by either pushing the start/stop button or adjusting the transmission to park. The battery indicator light was illuminated during this process, but no other errors were displayed. I connected a battery-powered jump starter within 3-5 minutes of the failure, and the vehicle started on the first attempt. The Auto Idle Stop system had worked as expected earlier in the drive and there were no other indications of any issues with the vehicle prior to the incident. My entire family's safety was at serious risk since we were stalled on a busy 6 lane road with no ability to move the vehicle to the shoulder and I had to avoid traffic to get to the trunk and under the hood and spend time connecting the jump starter and subsequently attempting to start the vehicle. We are yet to bring the vehicle to the dealership for inspection.

The Honda Auto Start Stop system has been taxing my battery through daily use and creates unsafe situations. On more than one occasion, similar to the following, I have experienced the Honda Pilot stop the engine via the A.S.S. System. Upon releasing the brake, the system attempts, but fails, to come to ignition and the electrical system lacks the ability to start the engine, creating a need to re-start (or attempt restart). On 1 such occasion, my family was traveling through a city on the interstate. After driving on the interstate for a few hours we came to a stop light and stopped. At the green light, upon releasing the brake, the Honda Pilot attempted to start again and failed. The car went completely dead in the middle of a 4 lane interstate with my family inside. The car did not start again until the 3rd time attempting to restart the vehicle. Approximately 10 seconds later than intended, we were able to clear our vehicle from the interstate intersection. On normal occasions, such as the course of business with the Honda A.S.S. System, driving in situations that would be categorized as "start/Stop" situations, the Honda A.S.S. System leads to stalled response and delayed lurching into traffic creating situations due to the delay in response. Multiple times this has been reported to my dealer. They acknowledge it as a "Battery" problem. They test my battery per HONDA WARRANTY and tell me it "Passes". They basically are just charging my battery and sending me out the door. The time between vehicle events is decreasing. Please help address this obvious vehicle shortcoming. There is no permanent means to disable it. Thank you.

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. I was at an intersection at 10:30pm and it was extremely dangerous as my car would not start and was completely black. I could not even turn on hazards or put the car in nuetral to move out of the way. I had to call 911 and have the police assist. My car was towed to the dealership and I am waiting for an update. This will be the 4th time I have had my vehicle there for service for an electrical issue.

When stopped at a red light, the car went into idle stop mode. When I released the brake, the car did not restart. The electrical flashed. An error message was displayed to put the car in park, press the brake and engine restart button. That did not resolve the problem. The car would not start. We could not shift it from park to move it. I was in the traffic lane on the down side of an overpass with limited visibility behind me. I was concerned about getting rear ended. The car had to be towed and the battery replaced. The original Honda dealership performs all routine maintenance with the most recent service in June 2022. There has been no prior indication that the battery was weak or needed to be replaced.
