general problems of the 2021 Honda Pilot - part 1

The multipurpose front camera just went out and a series of many warning lights came on in my Honda Pilot. The camera just stopped working for no reason, with no warning and never an issue before. I took my Honda Pilot to the Honda dealership service department to have it checked and resolved. The dealers resolution was quoting me $2,000. 00 just for the camera, with no labor or calibration, that is extra. They told me its a glitch in the Honda's system and that's probable why the camera stopped working. They told me they are not responsible for the camera and won't replace it. They showed no concern for safety and I had to pick up the vehicle if I did not replace, at my cost, the $2000. 00 camera plus labor and calibration which may be around $3000. 00 all told. I can't believe that if this is a known problem to Honda and Honda is aware of it in their system, why aren't they responsible to replace a faulty manufacturing problem. Honda is passing their problem to consumers at a cost of $2000. 00 just for a camera. This should be unacceptable and it is outrageous the fact that Honda knows of a problem in their system that creates a safety problem and still are allowed to have the financial burden put on the consumer with no accountability. I had 2 other recalls on file and nothing was done. With the warning lights on, I am very concerned of the major safety issue. I don't believe, I as a consumer, should be responsible for the cost of a manufacturing issue. Now I have a vehicle with a safety issue and an extremely high cost resolution. I wanted to inform you because I believe that I am not the only person this has happened too and hopefully you can address this issue with Honda. Thank you.

While operating with the auto shut off enabled, vehicle stalled. Warning lights came on directing the driver to put into park. Vehicle would not turn off/on, could not take out of park. At the time, vehicle was in bumper to bumper traffic in a construction zone causing a very dangerous situation for the driver. Vehicle was towed and 10 minutes after the incident, the vehicle could be restarted. This is the second time this has happened in the last 9 months. Unfortunately the first was not reported. This is completely unacceptable. Honda knows this is an issue and refuses to address it.

This is the major safety issue while driving with my family on a highway. Keyless control unit is failing when car stops. While on a highway, all the lights on the dashboard start flickering, alarm went off brake system got locked. I need to pull over, stop the car and restart the car again. The flickering dashboard problem persisted the whole day and alarm went off intermittently till it drained the battery. Problem is reproducible.

The contact owns a 2021 Honda Pilot. The contact stated that while driving at an undisclosed speed, the vehicle's rear brakes rub significantly to the point of prematurely wearing out the brake pads. Additionally, the instrument panel is failing and displaying all warning lights, and the side mirrors flicker while driving. The vehicle was taken to a local dealer where it was diagnosed to be NHTSA campaign number: 20v439000 (back over prevention, electrical system) however, the VIN was not included in the recall repair. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 75,670.

The vehicle has routinely had issues restarting from auto idle. When the vehicle turns off in traffic at a stop or stopped at a red light, then it will not restart and the vehicle will essentially be dead for several minutes and unable to be turned on or moved.

When driving. Car I hear crackling noice. I did research it has to do with electrical wiring under the dash. It effects all information on the display screen can not access maps direction phone calls won't work,effect radio from working,causes panel lights not to work heater & ac display information won't work caused ac & heater not working. Defrost won't work caused windshield to fogged up could not see through windshield lucky I did not crash or harm any cars it doesn't happen everyday but it has been happening more it could catch on fire. Problem been occurring since 2023. Happens all the time at least 3-5 times a week.

Auto idle stop activated at a stop light for the 2nd or 3rd time over a few years. Lifted foot off the break and stalled, the car went into park and I could not put it into neutral or drive. The odometer screen looked like it does when the engine is on. The battery light was on. I tried to turn down the radio and the volume didn't work. I tried pressing the ignition button to turn off the car entirely but it didn't work the first couple of tries. Once I was able to completely turn it off, it struggled to turn over when I tried to start the engine, which I've never had happen, but did turn over. Dealership wanted to charge $325 for a few hours of diagnostics which we declined.

There is an electrical malfunction which causes all of the electrical components to flash on/off, glitch. This has occured while driving but primarily when the vehicle is parked and unattended. I’m afraid it can short and cause a fire. The vehicle will turn istelf on and off repeatedly and rapidly while unattended. This has been going on for 2 years with our vehicle and not under warranty.

Auto idle stop stalled at a red light causing my car to not move and having to shut off my car in the middle of traffic. Once I tried to turn back on it wouldnt start at first. I had to do this twice in order for the car to come back on.

The car engine autorestart causes all sorts of problems. We have repeatedly had the warning come on and the engine stop while at a light or paused in moving traffic. We have replaced the battery and other parts. The safety issue is that the car totally stops while in traffic and we have almost been hit multiple times as we try to restart the car. You have to put the car in park and restart the engine due to "compression issues" or something else. That has nothing to do with being a branded title and everything to do with a safety issue. The car just stops and won't autorestart. This has happened several times in the last week and then yesterday other warning lights came on resulting in the car then not accelerating beyond 25 mph initially and then 45 mph. Imagine this happening on a highway. This is really scary as it has happened on an interstate when traffic stopped and at a traffic light. I called Honda and they acknowledged it was safety issue but written up as a warranty extension so they refused to cover the repair of the vehicle. I am therefore escalating what I believe you are already investigating according to articles I have seen.

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 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 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.

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.

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.

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).

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.

Rearview camera images ot appear on the dashboard screen.

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 infotainment screen blacks out completely and sporadically, but as of recent, almost daily. Sometimes for about 3-5 minutes. When this happens, the rearview backup camera is completely disabled, creating a blind-spot safety hazard, violating federal motor vehicle safety standard 111. This issue directly impacts back over prevention and driver visibility. I have multiple videos of this occurring. In 2023, a Honda dealership performed the most bus/fakra connector safety recall on this vehicle. That manufacturer recall remedy has failed, and the exact same safety defect has returned. I did schedule the vehicle for a formal diagnostic inspection at a Honda dealership this Friday to pull the network communication error codes. There were no warning lamps or warning messages prior to the system blacking out.

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.

The contact owns a 2021 Honda Pilot. The contact stated that while driving at various speeds, the vehicle unintendedly accelerated without the driver depressing the accelerator pedal. The security alarm randomly activated while the vehicle was parked and turned off. The check engine warning light was illuminated. The message "emissions system failure" and a key fob error message was displayed, and the vehicle failed to start. The vehicle was taken to the local dealer. The cause of the failure was not yet determined. The manufacturer was not notified of the failure. The failure mileage was 98,000.

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.

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.

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.

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 following warning lights: adaptive cruise control problem, lane keeping assist, collision mitigation system, road departure mitigation problem, auto high beam problem.
