2021 HONDA PILOT Electrical System Problems

The infotainment system has some major wiring issues that cause the screen to go black and disconnect which then renders the back up camera useless. There is a potential class action lawsuit over this issue. Lots of Honda Pilot owners have this same issue.

Center infotainment system screen shorts out and goes dark. Back up camera will not work and it is unsafe to back up as you can't see below the rear window.

Infotainment system is crackling through the speakers and then the whole screen goes black and nothing works including the back up camera.

The heat stopped working last year when parked. To the point where it's blowing out cold air. I brought it to the dealership and they told me nothing is wrong. It appears to be the thermostat which I now have to replace on my own. Also the transmission slips randomly and I was told that could not be repeated either. Yet the car only has 90,000 miles, this should not be occurring.

Auto start-stop system failed. The car completely shutoff when the engine idle was engaged in the middle of traffic.

The truck lights came on, with no reason, ACC and LKAS dealer wants to charge 200 just to diagnose, I keep hearing many have thir problem, honda needs to fix this problem that they know they have.

Infotainment systems makes a crackling sound then the whole system will shut down and screen goes black. Nothing with the system will work including the back up camera.

Vehicle spontaneously caught fire. There were no known/indicated issues with the vehicle. Vehicle was eventually extinguished by the fire dept. It took them 45 mins to render it extinguished. Vehicle was parked in my driveway at the time of the incident.

I have a 2021 Elite and have been experiencing issues with the Auto Engine Idle Shut Off for the past year. The engine with shuts off normally when I come to a stop when I have the system engaged. The problems begin when I take my foot off the brake expecting the engine to start up again. What happens inconsistently (though more and more often) is that when I take my foot off the brake, the engine shuts off, shifts itself into Park, and I have trouble getting the engine to start up again. A number of warning messages show up on the center console as well. Things like, Collision Mitigation Braking System, Road Departure Mitigation, Brake System warnings start displaying. Sometimes, I can get the engine to start up again within 10-15 seconds. Sometimes, it's been more than a minute. It almost sounds like the battery is dead but...

Like others have reported, similar to the odyssey we own that did have a recall to fix the issue, the vehicle fails to restart after it idles at a light. Causing very stressful situation in traffic because it take 10-20 seconds to get vehicle going. Happened 5 times in 6 months.

The contact owns a 2021 Honda Pilot. The contact stated while driving approximately 55 MPH, the contact stated that several unknown warning lights started flashing. The contact stated that the Cruise Control and the Lane Departure and Lane Assist were inoperable. Additionally, the front view camera had failed to operate as designed. The contact had taken the vehicle to an independent mechanic where the vehicle was diagnosed, and it was determined that the electrical system had failed and that the front view camera needed to be replaced and recalibrated for all of the other systems to work as designed. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was approximately 50,000.

ACC, LKAS, collision mitigation system problem, road departure mitigation system, and auto high beam problem warnings all appear on instrument panel. None of these systems work. Have replaced battery and problem not fixed. Warnings continue to appear each time car is turned on. Vehicle has 47783 miles on it. Codes indicate there’s a problem with the camera in the front of the car. The car is only 3 years old. Shouldn’t be having these issues. Have researched online and found many other complaints from others from various Honda models. Major safety problem that warrants a recall.

The battery has gone bad twice (second replacement only took nine months) since an update was applied to the auto engine restart function. The car will work for some amount of time after the battery is replaced and then begin to not restart (shut off) at a light after the auto engine shutoff is engaged from the brake. It progressively gets worse until we replace the battery.

Problem Dealer said recall for airbags risk/ seat sensor cannot be fixed due to unable to get parts.

The infotainment screen went black. No back up camera available.

The contact owns a 2021 Honda Pilot. The contact stated that while the idle stop system was deactivated, while idling at a stop light the vehicle suddenly turned off after releasing the brake pedal and shifted into neutral. The vehicle was eventually restarted and operated normally. The contact stated that the failure had occurred on multiple occasions. The vehicle was taken to the local dealer. The cause of the failure was not yet determined. The manufacturer was not yet notified of the failure. The failure mileage was 33,000.

When I’m stopped and try to drive my car it sometimes dies. It’s a big safety concern and happens often and when I have my kids in the car. I can’t get it to start again for a little while. The lights come on the dashboard but it won’t start at all until a while after trying.

This is regarding the MOST FAKRA Service Cables Safety Recall which affects the display in my car. It started off with the radio cutting out but has progressed to the display not working which affects the rear camera. I believe this is extremely dangerous. I have taken my car to the Honda dealership in Burlington, Iowa FOUR times and they have not fixed the problem. It's my understanding that they have not replaced the cable harness but have only "checked the connections" and in one instance, one of the maintenance workers told my husband that they simply "hit the dash" and it started working again. This dealership has been very troublesome to work with as they simply say that the screen never malfunctions for them. I don't believe this as I encounter a problem with the display EVERY time I drive it. I contacted the Honda Customer Support almost a...

When stopped at red light idle stop feature was active and car wouldn’t restart couldn’t turn the truck off or on all electrical components such as radio, screen and heating were on but engine wouldn’t start or stop

There appear to be more than one issue. When using the auto idle feature, my car will turn off completely. Meaning the engine turns off and it is difficult to restart. I also have issues starting the car from scratch. This has occurred multiple times where the engine will not turn on but other components will. I cannot be jumped or put in neutral as the transmission won't move out of park if the engine is not on. It has been to the dealership multiple times for both issues. A software update was done to fix the auto idle issue, but it has not fixed the issue. i know longer use the auto idle feature. The most recent incident was today.

The contact owns a 2021 Honda Pilot. The contact stated that the Auto Idle feature on the vehicle intermittently failed to operate as needed. The contact stated that the vehicle failed to restart upon the depression of the accelerator pedal. The contact stated that an unknown message was displayed on the instrument panel during the failure. The contact had taken the vehicle to the dealer on several occasions and software updates were performed; however, the failure returned soon after the updates were completed. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 30,000.

I was driving my Pilot and came to a stop during stop and go traffic on a highway. Normally the auto stop/start feature would stop the engine and start it again when I released the brake, but at this stop the vehicle stopped the engine and lost all power. The car went completely dead. As traffic started moving again I had no idea what was going on and my vehicle was in the path of moving traffic causing a hazard and safety risk to myself and others. I was able to restart the vehicle with the normal procedure, but it was in park and had to be shifted back into drive to get moving again. This became a normal occurrence so I took the vehicle to Honda for evaluation. They contend that the battery, while still "good", was not providing adequate voltage for the stop/start system. Proposed solutions were continue...

The car shuts down when coming to an idle such while stopping at a light. All systems are powered down including the hazard lights, front and tail lights and windows. The car has so far restarted after multiple attempts at the start button. This may range from 30 seconds to 5 minutes before the car will restart. This is a safety concern as when this occurs in traffic especially at night with limited visibility, this can lead to being rear ended waiting for the vehicle to start. When this occurs is unpredictable. The Honda dealer was unable to replicate the issue and as such carried out a software reset to address the issue. This has happened 8 times already.

The contact owns a 2021 Honda Pilot. The contact stated that the information center was not connecting. There were no warning lights illuminated. The vehicle was taken to the local dealer for NHTSA Campaign Number: 20V439000 (Back Over Prevention, Electrical System) and the vehicle was repaired but the failure occurred. The manufacturer was not contacted. The failure mileage was unknown.

Two weeks ago, the audio in my 2021 Pilot became very distorted also as if the car was losing power. On my way to work this morning, I reached a red light, came to a complete stop, and the vehicle went into idle mode as normal. However, while in idle mode the vehicle turned completely off just as I was about to release the brakes to start driving again. The battery indicator on the gauge clustor flashed a few times and the car automatically went into neutral. I was not able to put the vehicle back into park as instructed by the message prompt. After waiting a couple of minutes, I pressed AND held the start button and the vehicle finally turned back on. I do not know what the issue is, but due to this incident I felt that it was completely unsafe.

Honda Pilot 2021 Elite AWD w/ 34k miles shuts down at a complete stop e.g. traffic light, stop sign or highway stop and go rush hour. Panel says put in Neutral, but the push button transmission shift does not respond. Attempts to restart with the push start/stop button and fails multiple times first and then it starts again, while other motorists are honking behind you for blocking traffic. Major safety concern.

When going from stop light, car died in middle of intersection. Couldn’t get it started. Had it towed to dealership.Dealer did diagnostics and couldn’t find any issue. Drove car home. Turned it off. The car would not restart. Had it towed back to dealership. Not sure if it’s starter, alternator, auto engine stop features. Battery seems to be Gett drained. Danger is that the car randomly dies and won’t start. Dealer has no idea of the issue. Tow truck driver said he has towed severs Honda pilots with the same issue.

Audio system popping noise affecting the dashboard system and audio system not working loss of power controls to use any of the systems digital components including speed control backup camera entire audio system

The Entertainment system makes popping and crackling sounds and will cut out. This is very distracting while driving. It does not allow you to use the screen at all including to view backing up. I contacting Honda Corp and was told to get a formal diagnosis which is scheduled for June 16, 2023. Was also told this has happened many times before in other models of pilots.

Last week the the security alarm went off for no reason. The following day, I arrived to work and parked my car. 45 minutes later, I am notified my headlights were on. I ALWAYS keep my headlights on AUTO so they never should have been on. After I started my car for a minute, everything seems fine. 3 hours later, I hear an alarm in the parking lot but did not think it was my vehicle. I leave work and go to outside and realize my alarm has been going off for a couple of hours. I go to open my vehicle and try to start the car but all the whole dashboard lit up and the speakers were popping and making horrible noises. I could not get the car started and my driver seat kept moving on its own. I called Honda of Murfreesboro and they advised that I...

The contact owns a 2021 Honda Pilot. The contact stated that while driving in stop and go traffic, the Auto START/STOP feature malfunctioned causing the vehicle to lose electrical power and shut off. During the failure, the display and instrument panel became inoperable. Additionally, the turn signals were inoperable, and the shifter could not be shifted to neutral. Triple AAA was called to the scene and was able to get the vehicle restarted by recharging the battery. The cause of the failure was not yet determined. The local dealer was contacted, and a service appointment was scheduled. The manufacturer was not yet contacted. The contact referenced the NHTSA Investigation: PE22005 and indicated that the vehicle experienced a similar failure. The failure mileage was 29,000.

2021 Honda Pilot Black Edition with 37,007 miles. Navigation screen will display "Network Communication Lost" and "MOST Net Off" before completely shutting down for 5-10 minutes at a time, only to do the same thing after resetting. This is a known issue for Honda, hence Technical Service Bulletin 20-058 to cover a range of vehicles, including my 21 Pilot; most older covered vehicles are at 5 years 60k miles, but because my vehicle is newer, it isn't covered and is limited to 3 years 36k miles. I am having to pay out of pocket for these repairs. Contacted Honda and they couldn't help, stating my vehicle is out of warranty. It makes no sense to cover older vehicle but not a newer one when these issues are known and reported under TSB 20-058. Honda complaint Case # 13646867.

There is speaker cracking noise and monitor goes black when using navigation. This is distracting and dangerous do to myself as a driver and others. It is distracting and concerning that a new vehicle goes crazy and Honda has no idea how to fix this. I have taken the vehicle to get serviced 4 times and still there is no resolution.

My 2021 Honda Pilot's Idle-Stop System has been failing at random and dangerous times. The engine shuts off when Idle-Stop is engaged and as expected. However and until recently; when I release my foot from the break, nothing happens. The engine does not start. Restarting the engine has taken me to shift to park, turn the car off, wait a few minutes, and then it starts without any hesitation. Today this happened during a busy stop where I did not feel safe for myself or my passengers. The problem does not reproduce at my will or by performing any specific set of steps. After today, I'm nervous to drive with this system enabled. The problem never happens if I remember to manually disable the Idle-Stop System every time I start my car. Nevertheless, it's not a normal practice for me to have to disengage a feature that should work. This...

My car, a 2021 Honda Pilot, has a feature called "Idle-Stop" where the engine stops when the break is depressed, when the break is released, the engine is supposed to start back up. Twice in the past week, while at an intersection, the Idle-Stop has engaged, stopping the engine, but failed to start the engine back up. After this occurs, I could NOT start the car back up, the engine would not turn over. The first occurrence was at the turn lane of a very busy intersection and there were numerous cars blocked by mine. Thankfully after about 30 minutes, the car managed to start up. I took it immediately to the Honda dealership where they said the car needed a software update. The dealership said the battery was fine and that there were no other issues. One week later, the same thing happened, I was a stop light and...

Auto restart stalls the car when reengaging the engine after coming to a full stop

With the auto idle feature engaged (disengaging requires manually turning off the system with each vehicle start) while at a stop light the auto idle feature shut the engine off. Typically, when you release the brake the car start back up and you can begin to accelerate. Over the past few months the issue has stalled the engine, but restarted and give the warning "Collision Mitigation Braking System Malfunction." On the past 2 occurrences the engine has shut off completely and I have had to restart the car. This occurs when at an intersection or similar after going into a complete stop, so vehicles around you are ready to move. Once it took me opening the car door and closing it to get the electronics to allow the car to restart.

When the automatic engine shut-off is engaged during traffic stops, sometimes the power to the vehicle shuts off. It can happen at stop signs with out warning. The vehicle usually powers back up in Park.

Auto braking applies randomly cause brakes to lock up happens when driving in any conditions. This problem has already caused a minor accident with my vehicle due to brakes locking up and no throttle

New car battery and car died while waiting at a light. The vehicle idle/stop system kicked in but car was not able to restart. While lights were still available on dashboard, the emergency hazards would not show nor could I put the car in neutral. The dealer looked at this problem twice, first time stating this can just happen and this time they said the new battery was perhaps faulty and replaced the battery. Very dangerous situation as the car just died at the light and cars had no way of knowing the car was disabled as the hazards would not work. Had an emergency jumper pack and was able to move the car to get out of road before it died again- no option to push car as I could not put car in neutral. This is the 3rd time this issue with the battery dying has happened and...

The car's automatic engine shut-off feature when stopped at a red light failed to reengaged after removing foot from break the car shut down and the transmission button shifted into neutral and displayed a message that you must put your foot on the brake and shift the car to Park. The battery indicator light was flashing and everything turned off in the car. After doing this the car told me I must put my foot on the break and restart the car. It then allowed me to shift back into drive. The dealer was not able to recreate the issue, and no other things showed the issue other than the battery indicator lamp flashing on and off until the car was back in drive. The light I lost all power at was on a road with a 55 MPH speed limit. When the light turned green and the car lost...

Our Pilot is brand new - we started noticing popping and cracking sounds from the dashboard. It is pretty loud. We thought it was possibly the radio but it continues with the radio off. We thought it was the dashboard contracting/expanding but it happens in all weather. It has become increasing loud and consistent and now any sounds from the stereo, regardless of input, skip and glitch and we turn it off and the popping and cracking sound continues seemingly from the speakers. We took it to the dealership for repair but they said they can't repair it. This is not acceptable for a new car.

The contact owns a 2021 Honda Pilot. The contact stated while driving 30 MPH, he noticed that several warning lights illuminated and remained illuminated. The contact continued driving to his residence. The following day the warning lights disappeared. Several months later the failure recurred. The contact took the vehicle to the local dealer to be diagnosed. The mechanic related the failure to an unknown electrical failure and performed a software update to fix the vehicle. the contact stated that the failure recurred. The vehicle was taken back to the dealer but was not diagnosed. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 1,000.

Loud popping and crackling noise emitting from speakers. Cannot turn them off, and causes major interruptions in navigation, radio, entertainment. Dealer said Falkra wiring is faulty, but is back-ordered, and could not even give us an estimate of when it would arrive. Essentially told us to suck it up, but it is more than distracting (my daughter actually said it gives her a headache) and I'm worried about larger (safety) issues if the wiring is indeed faulty. What if my other electrical systems malfunction as well?

There is an issue with the electrical system in this car. The radio has intermittent static on any station and hands free calls drop after a short period. I have Googled this and it is a very common complaint on this type/year vehicle. I am concerned there are other electrical issues that may be more safety related. The dealer did a hard reboot of the computer, but nothing changed.

I was about to cross the border I was not driving faster than 3 mph when a few functions stop working

The dash crackles sometimes a little and other times it crackles constantly all across the dash. If the radio is playing, it interferes with the radio or using the Bluetooth. At first it seemed like something hit the windshield and now it's worse and crackles all the time. There was a recall on this recently but not for the 2021 Pilot. This needs to be fixed. It is quite distracting and annoying.

WHILE DRIVING FOR ABOUT AN HOUR ON THE FREEWAY THE SOUND TO MY BLUETOOTH AUDIO QUIT. THEN THE APPLE CARPLAY WOULD NOT CONNECT. WHEN I GOT TO THE GROCERY STORE TRYIN TO MANEAVER INTO A PARKING SPOT THE BACKUP CAMERA DID NOT WORK WHEN I PUT IN REVERSE. AT FIRST I THOUGHT I HAD PRESSED PARK INSTEAD OF REVERSE BUT THAT WAS NOT THE CASE. NOT UNTIL I PARKED, SHUT THE VEHICLE OFF AND RESTARTED IT DID EVERYTHING START WORKING PROPERLY ( AT LEAST FOR NOW). THE VEHICLE HAS APPROXIMATELY 1500 MILES ON IT. I HAVE BEEN READING ABOUT A RECALL ON NEWER PILOTS (Y7Y) AND WAS WONDERING WHY MY VEHICLE IS NOT INCLUDED SINCE I AM EXPERIENCING THE SAME ISSUE. I MENTION ALSO THAT TWICE AT ABOUT 500 MILES I EXPERIENCED THE CRACKLING NOISE IN THE AUDIO THAT HAS BEEN A PROBLEM WITH THE 2018 AND NEWER PILOTS.
