2020 HONDA PILOT Electrical System Problems

Honda Auto-Idle Start/Stop system does not restart. Auto-Idle system will engage and sometimes not restart. This happens while at intersections (red lights/stop signs) and in traffic. Vehicle cuts off and can take several minutes to get the vehicle to turn back on. When it happens, it puts my safety at risk, along with any passengers, and any other vehicles nearby that might not notice my vehicle is disabled. Dealer is unable to replicate the issue. Honda America is aware of the issue. First occurrence 9/17/2022. 6/24/2023, 7/19/2023, 8/16/2023, 8/23/2023 all additional occurrences of same issue. Several of these I have video evidence of.

I was stopped at a stop light with my auto-idle system engaged. When the light turned to green the auto-idle would not disengage leaving me stalled in traffic. When I pressed on the gas I got an error message about the 'anti-collision system' being offline. I had to restart the car to resolve the issue. The dealer/service center states no known issues.

When auto start/stop feature engages at times vehicle does not restart and will not restart. This has happened 5-6 times in heavy traffic leaving the car dead in the middle of the road until we repeatedly try to reset and restart.

Last week, my wife was picking up our 2 year old son from daycare in our 2020 Honda Pilot. She secured him in his car seat and placed her purse with the Honda key fob on the back seat and closed the door. The car somehow locked itself between the time she closed the door and attempted opening the front door, leaving my son locked in the back seat. The key fob battery had just recently been replaced so we are certain this is not a matter of the key fob battery being low. We needed to call the fire department to come and emergency open the car for us. Today, we did have a second key fob made at Honda for our vehicle so that we have a spare in the event this happens again closer to home. We are hoping to be reimbursed for this cost and the...

July 21,2023 Pulled of highway and car went idle at a light car turned off completely and didnt turn on car turned on after 2 minutes. August 13, same situation happened car didnt turn on for 3 minutes. In May car was serviced forr idle recall and I never had this issue until now. The dealer says its a weak battery. But it only happened when it was on idle and not when I turn it on. I had kids in the car and just got off highway. I could have had an accident. The 2nd time it happened it said to put the car in park and restart the car. There were no issues prior to the failure.

There is an intermittent problem with loud crackling noises coming from the speakers. The information center is turned off, but the crackling continues. It is either an electrical malfunction or a short of some sort. It is a distraction when driving and therefor a safety issue. There is a recall open with regards to the MOST cable for the camera but the camera does not have audio so it doesn't make sense that these would be related. We do not have many miles on the car and the information center is used primarily for navigation. Shutting it down in traffic is a safety issue because the driver is distracted. If this is an electrical short then there could also be a fire issue.

On three separate occasions, after stopping at a traffic light or in a parking lot, I was unable to move my car. The first time, the transmission dropped into neutral and I was unable to get it to any other gear . I had to turn off and restart the car multiple times to get it into gear. I was on a heavily trafficked road with multiple cars behind me at the light. Turned my flashers on and prayed to not get hit. The second time. I was in a parking lot and was leaving. I pulled into a space to look for something and got a message to put the car in park. I was unable to do so. Had to turn off and restart the car twice before It would go into park. I then turned it off and back on and was able to get it into...

My husband was getting off the highway when a car ahead of him braked suddenly. He attempted to hit the brakes, but the car did not stop. The automatic stop crash feature did not turn on. The abs did not work. Ultimately, crashing into the car ahead of him. Manufacturer Safety-related recall issued NHTSA #23V-174 Recall #FE5 2020-22 Multi-Model Door Mirror Glass Safety Recall Status: Remedy Available

Car completely shut down while in drive. Towed to dealership where I was told there was a software update that needed to be done. Car working fine now.

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...

Audio problem and the screen dashboard doesn’t work no connection Bluetooth we stop on the road trying to turn off the car but when we started we have same problem … I have videos I can’t upload

We had the recall repair done for the crackling speakers issue but it started again and is worse. The crackling sounds like rocks hitting the windshield and scares the heck out of everyone in the vehicle. Now when it does this we also get a network failure notice on the infotainment screen and then the infotainment system shuts down. Sure wouldn't expect these issues with a $50 K dollar vehicle barely over 3 years old with only 24 K miles on it. This has happened 4 times since it started again. That's 4 times in the past 3 weeks.

Electrical components for navigation, hand free devices, back Up camera & radio have an advisory from HONDA. Can has been into dealership multiple times claiming to be “fixed” but when delivered it is not. Wiring harness for radio is on back order for 5+ months, but dealership is unsure if this will correct the problem. Another concern is that 60,000 warranty is within 10,000 miles of expiring.

As I was driving vehicle it shut down. Dashboard went haywire as did the front panel, radio, windows. Could not turn on car at all, not even put it on neutral. Hazard lights did not work either.

The infotainment system screen will go black/turn off for several minutes, completing disabling the backup camera and other functions. Last week, the system went black completely and I tried to turn off / on the car multiple times but the infotainment system still did not reboot. I had to disconnect/reconnect the main battery to make the system to reboot. Few days later, the system went black again for a short period of time. When the system is up an running, there are many time that my concentration on driving has been disrupted by the sudden cracking and popping sounds stemming from the infotainment system. There is no pending recall on my car, so I do not what to do with my situation.

I pulled into my garage to turn off my 2020 Honda Pilot. I put my car in Park and set the Parking Break. I pushed the On/Off button of my car to turn off the ignition. The car failed to turn off. The electrical systems (radio, heating/AC displays) inside the vehicle turned off, but the engine continued to run. The error message "auto engine idle stop system problem" flashed on the dash. I tried multiple attempts to turn my car off. As I write this my car is sitting outside on my driveway, with the hopes my car will turn off. I have had previous issues with the auto on/off capability of my vehicle, to where the car would auto turn off and fail to turn back on. To combat this issue I always disabled the auto on/off capability of the vehicle. This car has had issue after issue from...

We purchased our 2020 Honda Pilot in January 2020. Shortly we heard popping sounds in the windshield. It became more frequent so we called our local Honda service and they didn’t know what was wrong. Later we called another Honda service and they knew what was wrong. We took our car in and they replaced some part in the radio electrical unit. It lasted a year and started doing the same thing again. Popping sounds and our display network would black out the whole screen as before. We lose our gps and backup camera and also no radio. We called Honda and they said it was the wiring harness and we would have to pay for it ourselves. There have been law suits filed against Honda for this very thing. Other owners have had the same problem we are still having. The popping sounds are very distracting while driving. Honda...

The entire infotainment screen shuts off, screen goes dark. So far it turns back on with no issues. The problem is intermittent. The USB phone connection also intermittently looses the connection. Sometimes it reconnects, other times I have to disconnect the phone and reconnect. I have changed the usb wire...same problem

In two, separate, instances the vehicle exhibited sudden acceleration with the brake pedal depressed. The first instance was, as the 2020 Honda Pilot was pulling into a driveway and was approximately 10 feet behind another vehicle parked in the driveway. With the brake pedal being depressed, as one does when parking, the 2020 Honda Pilot suddenly accelerated and struck the rear of the other vehicle. The automatic braking system was never deployed. The second instance was when the 2020 Honda Pilot was on a city street and was parked behind another vehicle on the right side of the street against the curb. The 2020 Honda Pilot was approximately 10 feet behind another vehicle parked against the curb. With the brake pedal being depressed, as one does when parking, the 2020 Honda Pilot suddenly accelerated and struck the rear of the other vehicle, driving it over the curb and into the...

Auto start/stop feature failed to restart vehicle and shifted to Neutral when foot was taken off the brake. Collision Mitigation Warning lights came on after vehicle power was shut off and turned back on to restart the motor.

There is a popping and crackling sound that comes from the speakers whether it is on or off. When this occurs the infotainment system, rear entertainment system, and blue tooth stops working. This happens every single time the vehicle is used. This causes distracting driving because the noises happen all of a sudden when driving. Second problem-the car seems to shut off and turn back on by itself after pressing the gas when its on auto idle shut off. For a few seconds when I let go of the brake peddle, instead of turning on from the auto idle shut off it just shuts off, then I press the gas and it turns on. It has done this several times that it is concerning and I fear it can cause an accident if it moves forward when I think it shut off on its own.

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...

Third time now that my speakers have been popping and crackling. All this leads to "Network Connection Lost" and the entire NAV screen goes black, also the main dashboard display sometimes...very unsafe. First couple of repairs were the connectors in the dash being replaced. This time my dealer has to call Honda for authorization. Received a call from dealer this morning that my battery was dead and this cleared out all of the warning codes, how convenient and it's only 3 years old. Now it needs to be kept until the warning codes "possibly" come back.

Frightening experiences with Auto Engine Idle Stop feature. My local mechanic, as well as the dealership where I purchased my brand new 2020 Honda Pilot Elite AWD were unable to address the issue. Have been experiencing electrical failures associated with my AEIS for about a year that have gotten progressively worse. At first, once disengaging from AEIS at a red light (by releasing my foot from the brake pedal) the radio would shut off and switch back on, but to AM radio. What seemed like a few months later, when AEIS was disengaging, my whole dashboard went blank and I received a message to "Shift to Park + restart engine". I have tried to be diligent in turning off AEIS immediately after starting my vehicle, but in the few times I have forgotten, and my AEIS has failed, the dashboard goes blank and the car shifts to neutral (indicated by...

The Auto Engine Idle function has been problematic for a while now, causing the engine to stall. It seems to have gotten progressively worse and now happens whenever I forget to disengage the Auto Engine Idle. One time in the spring of 2021, my husband had pulled into the intersection and was waiting for the chance to turn, only to find the engine stall and not respond to anything. It took a good almost two minutes of turning off the engine and trying to push the power button back on. It finally did turn on so we did not need a tow, but it was extremely scary to be in the middle of an intersection with a stalled engine. Subsequently the engine stalled a couple of times, briefly flashing an error message on the dashboard before shifting into Neutral on its own and then indicating to shift into Park. I...

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.

My vehicle has had repeated instances of the audio "infotainment" system causing loud, unexpected popping and crackling noises. During these instances, the infotainment system sometimes quits working completely and often the handsfree telephone function quits working. When this occurs, the volume control and audio on off button have no effect whatsoever. It can occur with or without my telephone connected to the system. The only way to temporarily correct the condition (and it only works sometimes) is to pull off the road, turn the car off completely, and then restart it. This issue has occurred during three seperate time periods, and each time, it has progressed from intermittent to continuous. The first time I took it to the dealer and they replaced some small wiring harness connectors. The second time, they had a Honda Field Engineer look at the car and replaced the entire dashboard harness system (July 2022). Then...

When I drive the 2020 Honda Pilot it has started to make a cracking noise when I turn or go over any bumps in the road. It cuts off navigation and phone conversations from my infotainment system. The cracking noise happens if the system is on or off. It makes it difficult to even carry on a conversation with someone in the car. Not what I expected when I paid over $40k.

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.

Stop/start system shutdown the engine and failed to restart while at stop light. It occurred twice on 9/8/2022 and twice on 9/9/2022.

I have owned the 2020 Honda Pilot Touring since Jan.2021. Up till now, theses similar situations have happened 4-5 times. It always happens when I am gradually slowing down to a complete stop at crossroads. My 2020 Honda Pilot has shut off a few times while stopping at a red light. Each time has been after coming to a complete stop at a red light and sitting there for a couple minutes. Suddenly there is a beep sound and the engine shuts down. Only the entertainment system is left on. The gear changes to N by itself and I am unable to change it to any other gear. With my foot on the brake, trying to change the gear and trying turn off the car for about 3 minute in the middle of traffic with my kids in the car, eventually I was able to shut off the engine completely...

I understand there may be an investigation of Honda's stop-start system, the system which is meant to improve fuel economy by shutting the engine off when the vehicle comes to a stop. I experienced this one (1) time while stopping at a traffic light, date unknown. The engine went off, as it was supposed to, but when I took my foot off the brake and pressed on the accelerator nothing happened, the engine had not restarted. I attempted to restart the car by pressing on the start button but since I was in Drive it wouldn't start. I think I tried to shift the transmission into Park (it's been several months since the incident) but I'm not sure if it shifted or not. I turned the car off by pressing the start button, waited briefly and then pressed the start button again to start, which it did. I shifted into...

Issues with infotainment system, a continuous crackling sound, sounds like electric spark. This occurs for several days and now the system is not working and this affects the operation of backup camera.

Vehicle has died when at a stop light, would not automatically restart. Days later the vehicle’s electrical system would not allow the car to start, many code warnings on display. Have had it towed. Battery would not jump and vehicle would not shift into neutral. Found out it needed a specialized tool only the Honda service had.

died and switched into neutral by itself, wouldnt start or switch into drive mode- in the middle of a busy intersection! it was scary and dangerous trunk doesn't open/close properly Infotainment center dies unexpectedly, freezes, won't restart on it's own. Have to pull over and restart car a few times or let the car sit off for a while speakers crackle at random times Took the car numerous times to Marin Honda, the computer they plug the car into showed "no codes" so they said there wasn't an issue. No warning lights of any kind. electrical just shuts down

Vehicle shut down and failed to start at stoplight. It was as of it shifted off or in to neutral. Battery light showed red when initially tried to restart. Finally engine started after tuning off and back on again. I believe it was a failure of the auto engine stop system currently under investigation. It has had repeated issues lately getting going at stop lights but this was the first couple shutdown

On multiple occassions, my Engine Auto Idle Start/Stop has malfunctioned. In particular, when the car goes into idle while stopped at a traffic light, there are times when the car completely shuts off. This is dangerous at any time because it has been unpredictable. The problem gets more frequent until finally the car won't start. Upon taking the car to Keating Honda in Conroe TX twice for the inability to start the car, I have had my battery replaced twice within the last year. They have not been able to identify any parasitic drains to the battery. At 39,000 miles, my 2020 Honda Pilot Elite required it's 3rd battery. The problem has been labeled battery failure, but frankly the problem has been the Engine Auto Idle Start/Stop feature and I am certain this feature is directly related to the battery failing.

The radio began making crackling noises. After a week or so, the entire system (navigation, clock, charging ports, dvd, radio/ sound system) stopped working completely. Shortly there after, the battery became completely drained. The dealership refused to honor the 100 month battery warranty, so I was forced to purchase a new battery. The radio & electrical system began to work again, but only for a week. Then the crackling sound began again, followed shortly thereafter with the entire system not working again.

My Pilot has approximately 25,000 miles. I was stopped at a red light, my vehicle has the ignition shut off feature, which engaged while I was stopped. When the light changed and I went to accelerate, instead of the engine restarting, the entire car stalled and would not restart. There were a variety of flashing lights and the car appeared to have power but the engine would not turn over. I immediately turned my hazard lights on, but each time I tried to restart the car, the hazards would turn off which was particularly concerning. The police responded and we looked for options to get the car into neutral so we could move it out of the intersection but there appears to be no option for a layman to manually override the transmission and place the car in neutral. As a result I was stranded in my vehicle for nearly...

Incident happened 3 times in 1 week (June 8th, 11th, & 15). When stopped at a light or in traffic the car shuts down. The engine does not restart when it's supposed to, leaving us with a dead vehicle. The car had to be jump-started to get the vehicle moving again. In worst cases, the battery doesn’t even hold a charge. Other issue would be when pressing the gas the car would stall sometimes before accelerating.

The contact owns a 2020 Honda Pilot. The contact stated that the vehicle was experiencing hard starts. Additionally, the contact stated that the Auto START/STOP function failed to engage automatically while attempting to drive from a complete stop. There were no warning lights illuminated. The contact stated that the failure recurred and the vehicle turned off while at a complete stop. The contact was able to restart the vehicle. The vehicle was taken to the dealer where the battery was replaced; however, the failure persisted. Additionally, the contact stated while driving through an intersection, the vehicle stalled. The contact was able to restart the vehicle after several attempts. The vehicle was taken to the local dealer where it was diagnosed that the battery needed to be replaced. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 30,000.

Auto Engine Idle engaged and the vehicle died and would not restart. The vehicle has died a couple of times in the past in similar circumstances but always restarted until the most recent incident. This left us stranded in the middle of the road at an intersection with no way to put the vehicle in neutral and push it to the side of the road which is another unrelated safety complaint. The car cannot be taken out of park when not running. The component has not been inspected as of the time of this complaint but is being scheduled for review by the service shop. There were no warnings or messages prior to the incidents occurring.

The infotainment screen in the vehicle which includes the backup camera display, navigation, radio, Bluetooth and other important vehicle functions and settings, shuts down and reboots in a continuous loop and sometimes turns off (blank screen) completely. This results in a backup camera function that is no longer useable as the screen does not/cannot display the camera image behind the vehicle. This is an SUV with a large rear blind spot that cannot be viewed simply by turning your head especially if there are short/small objects below the view of the rear glass. The other functions that rely on the screen also do not work and this constant rebooting/flashing is very distracting to the driver. There are also strange noises emanating from the sound system regardless of whether the system is on or off. This appears to be a widespread problem with this vehicle that still does not have a...

When the 2020 Honda Pilot sits for over 3-6 days, the battery goes dead. I have brought it to the Honda Dealership and they have checked out the battery and alternator and say it's working properly. I have jumped the Honda Pilot 6 times because of a dead battery and had the battery replaced once. Never had a vehicle ever do this before. Very dangerous for anyone parking and flying from an airport. Unbelievable!!!!!! This has been going on since we purchased NEW!

The infotainment system makes a popping/crackling sound. The dash display and infotainment display flickers on and off at times. This condition makes impedes the use of the the user controls and feedback systems. The vehicle went in for service on October 15, 2021 to have a technical service bulletin update implemented. The vehicle started exhibiting the issue again on February 9, 2022 in a much more extreme and severe way. It went back for service on February 15, 2022 to have the original work "inspected". The dealer said everything was fine and did nothing. Honda as implemented a couple of Technical Service Bulletins, but no permanent fix has been implemented. The dealer mentioned that they apply this TSB to approximately 2 Pilots per day.

I was driving and a LOUD cracking popping noise started coming from the dash. The stereo went dead and the instrument panel went dead. I was startled at the noise and almost lost control of the car. I can’t see my speed or other functions of the car. Honda has no permanent fix for this.

Since new, the audio/navigation system has repeatedly turned off and on, had crackling noises emitted from the speakers and issues system warnings. I retuned my first Pilot for the same issues and now this Pilot is demonstrating the same issues. I have had the vehicle at the dealer several times and they just say that it’s common with this vehicle model and the Passport with navigation systems. HONDA national service does not return calls and this issue is noted on many HONDA forums. This condition is unacceptable and dangerous.

Stopped and put the car in park and the entire vehicle shut completely down. No electrical power. Wouldn't start up again. Took about 3-5 minutes before I could restart it.

Head unit has supposedly been "fixed" already, still losing all electronics, black out screen, loud and startling popping noises. Been asking Honda to fix for months, assigned a case, they just do not seem to care and now vehicle is undrivable due to loud, startling sound that may cause an accident, as well as not knowing if any of the safety electronics are working or not. It almost sounds like shorting out and that means possibility of electrical fire. Honda is dragging their feet doing ANYTHING on this obviously as this has been going on for months.

My vehicle was recalled twice before 2,500 miles for wiring harness connector issues (snapping, popping, crackling). I was told I could lose visibility with all dash functions, navigation, radio, etc. After the first and second recall service fix I continued to experience the same symptoms. I opened a case with Honda in June, 2021, and notified my local dealer. The Honda case number is 12314702. I have heard nothing from either Honda and my local dealer, and I am concerned nothing is being done on this issue and I will lose visibility of my dash at some point, putting myself and family in danger.
