2021 HONDA PILOT Electrical System Problems

The contact owns a 2021 Honda Pilot. The contact stated that the infotainment screen and the rearview camera screen intermittently failed to activate while the vehicle was shifted into reverse. The vehicle was taken to the local dealer, and the contact was informed that the VIN was not included in NHTSA Campaign Number: 23V431000 (Back Over Prevention). The vehicle was not diagnosed or repaired. The manufacturer was contacted; however, no assistance was provided. The failure mileage was approximately 32,000.

The auto-idle feature on this vehicle stalls out the engine on a regular basis, causing risk of accident from surrounding traffic. When breaks applied for red light, stop sign, traffic, etc., the auto-idle feature first engages and powers down the engine, however upon releasing the breaks, the engine stalls out, shifts into neutral, and the battery light comes on. I then have to get it into park and try to restart the vehicle. Sometimes it starts right away, other times it can take a few tries. Meanwhile, cars behind me are honking because I can't get my vehicle to move forward with traffic. Several times I have almost been rear-ended because the car behind me is expecting me to move forward when they see my brake lights turn off. I've talked to my dealer who informed me they completed a auto-idle recall software update in 2023 (recall #23-008) but the...

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...

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...

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....

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...

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...

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,...

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.

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.

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...

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...

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.
