2021 HONDA PILOT Electrical System Problems

We were driving our 2019 Honda Pilot and at a traffic light the car failed to restart after the auto stop-start system shut off the engine. This happened when I started to step on the gas so we could have been rear-ended by the car behind us. The brakes also appeared stuck when I tried to depress them so I could restart the car. There was no warning until the car refused to start, but the computer system did appear to do some sort of a reboot sequence.

Car does not want to start even though the batter and alternator are good (tested by tow truck company). Restarts fine once batter is disconnected and then reconnected again. This has now happened twice.

While stopped at an intersection, the car died, the transmission shifted to neutral automatically and the radio would not turn on. The AGM battery was replaced approximately one year ago when a similar situation took place.

The infotainment system screen would simply not illuminate when the car is started. Also the auto engine shut off, chooses not to restart the engine when your foot is removed from the break peddle.

The contact owns a 2021 Honda Pilot. The contact stated that the vehicle was repaired under NHTSA Campaign Numbers: 23V174000 (VISIBILITY), 24V064000 (AIR BAGS), and under TSB: 0101T0. The contact stated that the dealer did not repair all the recalls. The contact stated that in the driver’s side mirror, the image appeared wavy and resembled a funhouse mirror. The TSB regarding the coaxial cable terminal (FAKRA) was not repaired properly. The contact stated that when the vehicle was started there was an abnormal popping and crackling sound coming from the speakers. The contact returned the vehicle to the Service Department to have the vehicle re-examined; however, the dealer refused. In addition, the contact stated that the rearview camera displayed a distorted image while the vehicle was in reverse(R). The dealer stated that the camera was on fish-eye mode. The dealer switched the lens and cleaned the camera. The manufacturer was not made aware of the failure. The failure mileage was 84,436.

While driving on the freeway at a slow speed due to two freeways merging, my Honda Pilot suddenly stopped/stalled. When I tried to restart the car by pressing the Auto Idle Stop button to vehicle did not start. It took three times of pressing the Auto Idle Stop button for the engine to restart. I am lucky that the traffic was going at a slow speed due to the merging of freeways so I was able to right away press my emergency signal lights on. I panicked and was scared for my safety and what could have happened to myself and others if the vehicle was running at a higher speed. This could have caused a major accident. Because this happened yesterday, I will be calling Honda to report the issue as well and have my vehicle inspected. My vehicle has had issues many times in the past with the Auto Idle Stop button not starting, however, it has never happened while driving. The concerning part as well is that the vehicle did not give any kind of warning light or message.

Honda’s Auto Idle Stop system shuts vehicle off when at a full stop and fails to restart after removing foot from the brake. Instead, when you remove your foot off the brake, the vehicle switches to neutral or park and does not restart despite following on screen instructions to restart (Example: switch to park, put foot on the brake, and press start button). We have to put the hazard lights on and try the steps over and over again until it restarts. This is a major safety issue, especially when at a traffic light or in heavy traffic, where every second counts and you have to worry about someone not noticing that you are stopped or have hazard lights on and plows into you.

Wife was driving car and it stalled when slowing down for a red light. No check engine light or dash warning notices. Car then displayed instructions to restart the car Tried to restart 4 or 5 times. Finally started. We were lucky she was not on a highway driving at highway speeds.

Component inspected by Honda dealer It’s the forward camera it has already malfunctioned and no longer works I only have 62,000 miles on my pilot. This seems excessive there is definitely a defect in these vehicles. The incident is the warning lights that came up and no longer worked

Car is slow to start or doesn't start at all, particularly after frequent engine stops/starts or when engine has idled for a period of time. Battery has been replaced. Symptom comes and goes, but seems to get worse with frequent engine stops/starts (i.e., driving to different locations with short stays at each, or with the automatic engine shut off)

The front camera which controls all of the safety features went out! 1 week ago. It has been confirmed and I am now having to pay almost $2700.00 to have it fixed. I am really upset to see how many issues this year of the car has. And the fact that Honda has known about it since 2019 and did nothing to fix them. There are 318 complaints on this car and I’m guessing over half of them have to do with the front camera. It is showing 5 safety codes.

Vehicle: 2021 Honda Pilot VIN: [XXX] Complaint: My 2021 Honda Pilot continues to have the same issues described in NHTSA Recall 23V-431 (backup camera / infotainment coaxial cable defect). The recall was marked “completed” about two years ago, but the safety problem persists. Symptoms include: •Infotainment screen going black •“Network communication lost” error messages •Backup camera flickering or failing to display Because the backup camera is federally required under FMVSS 111, my vehicle is not compliant with safety standards. The dealership told me that since the recall was already performed, I would now have to pay out of pocket for further repairs. This means the original recall remedy either failed or was not effective. I am filing this complaint because Honda and its dealership are refusing to correct an unresolved safety defect, leaving my vehicle unsafe to operate. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

rearview camera images ot appear on the dashboard screen

I have two issues. First issue is the car will hit an intermediately not start once shut off and will take a few times of making sure the car is completely shut off opening your doors letting it power down before being able to restart. The next issue is the forward collision notification will randomly beep at every car that goes by specifically white cars. And also the adaptive cruise control brakes a little bit harder than expected.

The contact owns a 2021 Honda Pilot. The contact stated that while at a complete stop with the START/STOP feature activated, the engine shut off while depressing the accelerator pedal. There was no warning light illuminated. After waiting for several minutes, the contact had to perform several procedures to restart the vehicle. The vehicle was initially taken to a dealer where a software update was performed; however, the failure returned weekly. Recently, the contact stated that upon restarting the vehicle after the failure, the vehicle began to jerk while accelerating, with an abnormal tapping sound coming from the engine. The vehicle was taken to a dealer and was diagnosed with a defective engine rod bearing. The contact was informed by the mechanic that the repair could not be warranted. The vehicle was not repaired. The manufacturer was notified of the failure but offered no assistance. The contact was referred to the NHTSA Hotline to report the failure. The vehicle was not repaired. The failure mileage was approximately 15,000.

Mileage: 15,000

My 2021 Honda Pilot SE has developed a failure of the forward-facing Multipurpose Camera Unit (mounted behind the rearview mirror). A scan with a professional tool confirmed Diagnostic Trouble Code U3000-49 – “Multipurpose Camera Unit Internal Electronic Failure.” When this occurs, the vehicle immediately displays multiple warning lights at every startup: Collision Mitigation Braking System (CMBS), Lane Keeping Assist (LKAS), Road Departure Mitigation (RDM), Adaptive Cruise Control (ACC), and Automatic High-Beam/Dimming headlights. In addition, the dashboard shows a “brake system failure” message, although the brakes continue to function normally. This single camera failure disables all of Honda’s Honda Sensing crash-avoidance features, leaving the driver without forward collision prevention or lane-keeping systems. The failure is persistent, and the DTC remains “Current” after clearing. I took the vehicle to a Honda dealer, but because the car is out of warranty they refused to perform diagnosis or provide a repair estimate, essentially telling me it was my responsibility to resolve. This problem is widely reported by owners of Pilots, Odysseys, CR-Vs, Accords, and Passports, all showing the same U3000-49 code and symptoms. Independent shops confirm they often see these failures, and forums show repeated cases of owners paying high out-of-pocket costs, sometimes with parts on back-order. Honda has recalled less serious issues, such as rearview camera display faults, while this defect disables forward collision prevention and lane safety systems—far more critical to protection. Other automakers (Toyota, GM, Subaru) have recalled forward cameras and radar modules under similar conditions. This is a major safety defect that removes federally promoted crash-avoidance systems with no fallback. I urge NHTSA to investigate and require Honda to issue a recall at manufacturer expense, and please advise how long the process may take, as my vehicle is less safe to drive

When stopped at a stop light the auto idle stop turned the car off. When we tried to go at the green light the car wouldn't move. The transmission shifted to neutral and was stuck. We couldn't put the car in park, we couldn't turn the car off, we couldn't put it in gear. We considered calling the police for help since we were stuck in an intersection. The car eventually turned off and we tried pushing all the buttons to do something it finally allowed us to turn the car 100% off and restart it. Then we could go.

The contact owns a 2021 Honda Pilot. The contact stated that after coming to a complete stop, the START/STOP function activated and turned the vehicle off; however, while attempting to drive from the stop, the engine failed to restart. After waiting 5-10 minutes, the vehicle was able to restart and returned to normal functionality, but the failure became a regular occurrence. No warning lights were illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 44,000.

My 2021 Honda Pilot SE FWD would not restart after the auto off/on turned my engine off at a stop light. Of course this happened at a busy intersection causing backup and an unsafe environment to get out and inspect the vehicle. The car had to be jump started by a kind individual.

All I did was simply change my battery. Up until this point the car had run perfect and no issues or warnings. Now after placing the correct AGM battery the dash has lit up like Christmas. I am getting ACC, LKAS, Auto Head light, forward collision and Brake System warning lights. I was informed that this is a very costly repair, a camera needs to be replaced and recalibrated, $2000 estimate. This should be a recall based on the other numerous complaints I'm seeing. I reached out to Honda with no response as of yet.

screen stopped working suddenly. will randomly flash bright blue or a gray static, then go back to black.

The Auto Idle Stop (AIS) feature on my 2021 Honda Pilot intermittently causes the engine to shut off at a stop and fail to restart. When this happens the vehicle remains completely unresponsive until I shift into Park and manually restart the engine.This has happened multiple times in traffic and at intersections, creating a huge safety risk. I have already replaced the battery and had the latest software update installed at my local Honda dealership, but the issue persists. The problem is intermittent and difficult for the dealership to replicate. The auto idle stop issue is a known problem with Honda even extending a warranty coverage for the starter assembly and starter relays. The NHTSA number EA25004 addresses this yet the local dealership will only update the software and change the battery. They are failing to honor the second stage of the repair calling out specifically replacing the starter assembly, starter relays and adjusting the valves.

The contact owns a 2021 Honda Pilot. The contact stated that while temporarily stopped at a traffic light or a stop sign, the vehicle occasionally shifted into neutral, or the vehicle shut off unintendedly. There was no warning light illuminated. The local dealer was contacted; however, the vehicle was not diagnosed or repaired. The contact was informed that the VIN was not under recall. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 68,000.

Mileage: 68,000

The contact owns a 2021 Honda Pilot. The contact stated that the idle STOP/START system suddenly activated while idling at a stop sign, stop light, and driving at slower speeds of approximately 5 MPH. The vehicle stalled while the failure occurred, causing the contact to make several attempts to restart the vehicle. The failure was more persistent. There were no warning lights illuminated. The dealer was contacted, and it was confirmed that the diagnostic test and repair were not covered under the recall. The vehicle was not diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 62,000.

The camera in the windshield used for collision mitigation, cruise control, lane keep assist, auto high beams, etc. has been found to have gone bad and need replaced by the Honda service center near me. The dashboard indicates all of these issues and disables the use of these safety features. The cost to repair is $1900 which includes camera, installation, and calibration.

The BCM body control module is not working. My wife is scared to drive thinking it can turn on lights wipers and other components. For being a Farley new car it’s crazy to think it’s defected. I had no warning prior to the incident. Honda dealer says they don’t know what caused it The alarm goes off all the time so I have to have it in the driveway with the battery unplugged Honda charges me $2,100 to fix it which is absurd

While driving the CMBS (crash mitigation braking system) turns on at random timed intervals causing sudden breaking and jerking of the steering wheel towards center. This causes severe safety issues including increasing the chances of a wreck due to wheel jerk movements during turning and sudden breaking. The CMBS error message pops up on the touchscreen and during the episodes of sudden onset the entire digital display both on the gage cluster and entertainment center go black and an audible clicking is heard in the steering column.

Auto start/stop feature turned off the engine at a stoplight. When the light turned green and the brake pedal was released, the engine did not restart. There also appeared to be some sort of electrical malfunction since the start stop button would not turn off the ignition system in an attempt to reset the vehicle. This happened on a light regulated highway with a posted speed limit of 55 mph.

No FIRENo INJURIES0 DEATHS0 The collision mitigation braking system problem, adaptive cruise control problem, lane keeping assist problem, road departure mitigation system problem and auto high-beam problem. All these are keep showing on my dashboard. It is stated that this is the Multi Point Camera RADAR avg cost repair 2000.OO

Vehicle when trying to start locks up, have had the battery alternator starter checked, changed the brake switch and still having issues with hard start to my 2021 Honda Pilot. When this happens all the lights come on. I push the Idle/Start switch when I do get it started so that it does shut off when I’m at a red light or stop sign. Because I’m afraid it will not start. Dealership could not find any issues with the vehicle, I’ve taken it to another mechanic and they could not. It has been put on diagnostics several times. I keep putting money into trying to find out what the issue is!!!

This seems to be an on going problem for many Honda owners according to the forums. My Adaptive Cruise Control, lane keeping assistant, collision mitigation, road departure mitigation, and auto high beams have all gone out after going to the car wash. I have cleaned the windshield but I find it crazy that this is a common problem and there is no recall.

The contact owns a 2021 Honda Pilot. The contact stated that after idling at a red light, the Auto Start failed to operate as designed. The contact had to shift to park(P), and several attempts were needed to restart the vehicle before the contact was able to continue driving. There were no warning lights illuminated. The vehicle was taken to the dealer, who diagnosed that the battery had failed and needed to be replaced. The battery was replaced; however, the failure persisted. The vehicle was not taken to the dealer to be diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 33,000.

Mileage: 33,000

The car on multiple occasions (4 separate incidents) after stopping at a red light or stop sign and the auto stop system stopped the engine, once the brake pressure is released, the car would auto start then immediately shift into neutral and completely shut off (engine, electrical, etc). Driver would have to coast/stop at side of road and turn car off and on again. In 2 of the incidents, this happened on a two lane road and completely blocked traffic until the driver could figure out what was happening and restart the car.

Engines sometimes fails to start again after being turned off briefly. Will have so turn off all electrical and push button to start multiple times before it engine starts again

Starter bad

The side curtain airbags deployed while I was sitting in the passenger's side of the car looking into the glove compartment for about ten minutes with the car being completely off and parked in the driveway. The Ignition was off and there was glitching and clicking sounds seconds before the airbags deployed. This could have happened at any point while driving on the street or the freeway. It could have caused an accident and could have killed me if it happened elsewhere. It could have been the passenger's side airbag that deployed and I could have been seriously injured. This incident happened on a Sunday, so I had the car towed to Honda the following day. Honda's response after investigating: "We contacted American Honda Technical Support. Our American Honda District Rep informed us to have the customer contact her insurance provider for repairs." Aside from this official response, I was told that they investigated what they could and found no reason as to why the airbags would have deployed. I was told I had two options. Pay for repair with them or report it to the insurance. I stated that the release of the vehicle was a liability if I decided to not pay for repairs with Honda. After some dialogue, they helped with a loaner car and did not release the car to me. There were no warning lights or messages on the dash whatsoever. About a month prior to this incident, the car started alarming randomly. The random alarming would stop when disconnecting the hood latch sensor. I took the car in for a diagnosis and Honda reported that the cause of the alarm was the keyless access unit. The car (screen and dash) would still glitch after the hood latch sensor was disconnected. My hope is that Honda & American Honda admit responsibility & provide a solution not only for me but for all Honda Pilot owners that may be in danger. Investigating should be a priority, but even if repairs are done to my vehicle, I no longer feel safe driving a my vehicle.

My push start is not starting the car. Then while driving the car will shut off on parkway, at a light and won't start. This has been going on since I purchased the vehicle 9/23 I have warranty and th auto dealership keep acting like they fixed it yet the haven't. This is the most dangerous issue. We can die getting hit from behind or the car can catch fire keep pushing start button and not turning on

I have had numerous issues with the car stalling while in idle- it will shut off but still display all the warning lights on the dash. It would require the car engine to be restarted. Has happened at stop signs, stop lights, carpool lights. This has happened at least 10 times over 3.5 years. Last week I had a similar issue but this time it was much scarier- it did that same shut off but completely shut off the engine. All systems were black and the start button did not trigger a response for at least a minute. Once it finally restarted it displayed a “lost power” message on the screen. More similar issues to report.

After contacting the dealer several times, I’ve been told the parts for the recall are unavailable and it has been more than 6 months. The recall is over air bags that may not deploy correctly. Additionally, the electrical panel is periodically going out, the electrical on the seat isn’t working, and the car charger isn’t working. Finally, the car hesitates when going from reverse to drive. It won’t go and then I have to press the accelerator hard and then the car jumps. This is after I’ve had the radio fixed for incessant crackling from a different recall. The car seems unsafe.

Autostart failed several times then starter ultimately failed. Taken to dealer and repaired at my cost.

Brake system light on, Adaptive Cruise Control problem and Road Departure mitigation system problem error messages. Brakes light turn on randomly, even when car is off. This intermittently causes issues with acceleration pedal not responding while driving as well as being able to start vehicle without depressing brake pedal which is a major danger if kids are inside and pushes the button. Unable to accelerate when needed also causes problem that can lead to a crash.

None of the safety sensors were working.

The sensors stopped working when the infotainment screen went out. It goes out all the time. Honda knows of this issue but does nothing to repair.

While driving at freeway speed the gauge cluster including speedometer, gear selection, and navigation system shut off. The speedometer area was blank and the navigation screen said "network connection lost" No MOST network. It began to come back on a minute or 2 later. The MOST cable recall work has been done.

Audio and backup camera panel popping noise and disconnects whole panel causing it to go black , which includes the backup camera. Extreme safety issue with no backup camera .

Our vehicle continues to randomly turn off and not go while driving. Whenever the idle start/stop is engaged, the vehicle will randomly not restart when traffic is moving. When this occurs you must completely turn off the vehicle, wait a few seconds, restart the vehicle, wait a few seconds, then attempt to place back into drive before being able to move. We have been having this same issue many times now. We have taken our vehicle in to the dealer service department multiple times with this issue. We have replaced the battery ($400) and it still happens. They act like they have never heard of this happening to anyone before and we must be "making it up". They then proceed to tell us that we need to let it keep happening until it is much more common. Then bring it back in again so they can see it happen. I complained to Honda USA with the same story, being that it keeps happening over and over, and they gave us the same answer..."wait until it happens so the mechanic can see it" as if it has never happened to anyone else before. This is going to end up causing people serious harm or worse. Honda is obviously trying to play down the issue to avoid cost at the expense of consumers.

1) Recall 2020-22 multi-model seat weight sensor safety recall. Called since February 2024 when it was posted. I called the dealership and was told that I will received a postcard by mail. I have been waiting for the postcard and called multiple dealerships multiple times. I have been told that they don't have the parts to fix the issue and be put on the waiting list until further notice. 2)The screen goes off or it goes blurry. 3)The Car charger goes out sometimes too.

Infotainment screen goes blank all the time. Nothing at all on the screen including back up camera. Now it is causing the other sensors not to work so you don't know if you are close to hitting something. Honda has had this issue now for years.

The infotainment screen was black and not working at all so no back up camera. Also all the sensors warning you that you are getting to close to hitting something stopped working.

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 I have zero issues ever starting the vehicle initially in both hot and cold weather. When I disengage the system, which I do practically every time I drive the car now, everything works fine. The dealer ran a diagnostic and found nothing and then charged my battery even though it read full charge. It did the exact same thing a day later at a stop light. Because it’s a safety hazard and rather embarrassing to have it keep occurring at red lights with people behind you, when it shuts the engine off I manually disengage the shut off via the button on the console and the vehicle starts up fine every time. The stalls only occur when I don’t disengage with the button and take my foot off the brake. I have spoken to several other pilot owners that this has happened to so I know it is not an isolated incident.

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.

Mileage: 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 month ago. They followed up with my husband two weeks ago asking for receipts from the dealership which we did not have. He informed them that the dealership should have them on file although the receipts never described what they attempted to do to fix the problem. Since them, I have followed up with Honda Customer Support TWICE and am not able to receive any sort of reply from them. I am at a loss with what to do as I don't feel comfortable driving my car but have no other option to. I heavily rely on my display and its back up camera features. It is greatly increasing my risk of a crash every time I drive it.

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.

Mileage: 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 use but manually deselect auto start/stop function each time I started the car or replace the battery (at my expense - not covered by warranty). I am reporting this due to how the vehicle handles this lower voltage state of the battery. I think it if the vehicle senses this situation it should 1) notify the driver of the low voltage state of the battery and 2) automatically turn of the auto start/stop function of the vehicle thereby preventing an unsafe and startling vehicle shutdown while on the road and in traffic. This is an unsafe vehicle reaction that should not occur with proper system programming. I confirmed with the dealership this is a normal occurrence when the battery falls below certain voltage requirements, but the operator of the vehicle has no prior knowledge when this situation might occur (ie no warning light). This creates a potential for vehicle accidents and personal injury. Some type of warning and automatic suspension of the auto stop/start feature should occur.

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 needed to get my vehicle towed. I receive a call the next day and I was told that it had an electrical malfunction and the entire keyless access control unit needed to be replaced along with the connector ends. I have had several issues with the 2021 Pilot and this takes the cake. First it was the auto/stop at a red light and it completely shut off the engine. I had to turn the vehicle off and shift to park and then start the car. Also my "warning brake" lights come on randomly which alarms me and it will shift the car over. I also have had some issues with getting on an entrance ramp and the car doesn't want to pick up speed and I push the gas and the RPM's rev. This vehicle is unsafe.

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 problem has not been reproduced or confirmed by a dealer or independent service center. The component has not been inspected by the manufacturer, police, insurance representatives, or any others. There were no warning lamps, sounds, messages, or other symptoms prior that would indicate an imminent failure.

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 the Idle-Stop feature stopped the engine and it failed to start back. My 2 children were in the car this time, I felt very much that our safety was in danger. This time, I needed a jump start to get the engine started.

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 dealer cannot supply an answer except to swap out the battery. Less than 1.5 years old and <26K miles.

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 all power there was another vehicle approaching, but I was not able to get the car moving fast enough to get out of the way.

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.

Mileage: 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.
