On June 3, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE22005 after the agency received VOQs and several field reports concerning the Auto Idle Stop (AIS) feature on 2016-2019MY Honda Pilot vehicles. The complaints allege that the engine fails to restart on its own from a complete stop at a traffic light or road intersection with the AIS function engaged. The subject vehicles are equipped with a 3.5L engine with a 9-speed automatic transmission. On January 6, 2023, Honda released service bulletins 23-008 and 23-009.

The car alarm goes off on its own,and the dashboard lights flash even when the car is turned off ,this continues until the battery dies and the car won’t start. I’ve taken it to the mechanic several times and no codes come up; I’ve replaced the battery with a new one twice.

My wife operates a 2020 Honda Pilot Touring, purchased new and currently with approximately 60,000 miles. The vehicle's automatic idle stop/start system intermittently shuts the engine off while stopped in traffic but fails to restart when the driver releases the brake and attempts to proceed. The driver must shift the vehicle into Park and manually restart the engine, leaving the vehicle unexpectedly immobilized in active traffic. The vehicle was previously brought to Atamian Honda in [XXX], in spring 2026 for this same defect. Honda performed a corrective repair, but the identical failure has returned approximately six months later. The driver now feels compelled to manually disable the automatic idle stop feature every time she starts the vehicle to avoid another failure. We believe this represents a serious, unresolved safety defect and are particularly concerned that the condition has recurred after a previous manufacturer-directed repair. We request that NHTSA document this repeated post-repair failure and consider it in its ongoing evaluation of Honda idle-stop restart safety issues. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On four occasions, my 2021 Honda Pilot SE AWD (VIN [XXX]) has shut off at a stop under the Auto Idle Stop system and then failed to restart, leaving the driver stranded. The incidents happened on XXX, XXX, XXX, and XXX in and around [XXX]. Component: The starter system and the Auto Idle Stop engine restart function. Honda has acknowledged this exact condition in Service Bulletin 23-009 and Warranty Extension 23-009/23-010 (“Engine Does Not Auto Restart After Entering Auto Idle Stop”). The listed remedy is a software update, a valve adjustment, and replacement of the starter assembly and starter relays. The vehicle and the original starter are available for inspection on request. Safety risk: The engine shuts off at stops as designed, then will not restart. The vehicle is left disabled at intersections and in traffic with no warning, which puts the driver and passengers at risk of being rear-ended and stranded. My wife has been stranded four times. Idle Stop turns itself back on every time the car is started, so the driver’s only protection is remembering to switch it off manually on every trip. The fourth failure happened when she forgot. Dealer confirmation: The Honda dealer in [XXX] has performed Product Update 23-008, the PGM-FI Idle Stop software update XXX, and a valve adjustment XXX. The failure has continued after both repairs. The dealer has not replaced the starter assembly and relays, which is the remaining step of Honda’s published remedy. Manufacturer involvement:

While stopped at red light or stop sign the car goes into engine auto off mode when the brake is pressed. When then trying to go, the car is turning off or going to neutral. This causes vehicles behind me to stop suddenly and can cause an accident. The only way to then go is to turn the vehicle off, and restart, then put back in drive. This is happening very frequently and again is a safety hazard for me and others.

The auto idle stop feature will turn my engine off like it's supposed to, but then my engine dies when I try to accelerate again. This is happening more and more. I would allow my car to be inspected. My car tried to roll backward into the car behind me today, and I have held up traffic each time this has happened. I have seen on chatrooms that other honda pilots have this problem. No one has inspected my vehicle. This time my car went into neutral and flashed an alert that my car was now in neutral.

To Whom It May Concern: I am requesting immediate escalation of a serious safety concern involving my 2021 Honda Pilot Touring, which I purchased as a Honda Certified Pre-Owned vehicle directly from Tempe Honda. I also purchased additional warranty coverage at the time of sale. I have owned this vehicle for less than two years, and it has already required service for an issue involving the automatic idle-stop system. That issue remains unresolved. More recently, the vehicle has begun unexpectedly shifting into neutral without any action on my part. This has occurred on multiple occasions, including when transitioning from reverse into drive and, most alarmingly, while attempting to accelerate from a complete stop at a traffic light. During these incidents, the neutral indicator actually illuminates on the dashboard. This is not simply an inconvenience or a minor performance concern. It is a potentially dangerous malfunction that places me, my passengers, and other motorists at risk. I am particularly concerned because I am a single mother who relies on this vehicle for daily transportation, including transporting my child.

The Information screen goes blank. Then at that point the backup camera will not show on screen when backing up. Creating a blind spot and hazard

Refer to [XXX]. My honda pilot started having electrical issues where the car alarm would go off randomly, radio would play at volumes randomly, dashboard lights would flicker on and off, interior lights would turn on, headlights would turn on. This resulted in multiple drained batteries and left the car inoperable until it could be jump started. This is a safety issue because if we drove somewhere without cell reception, could be stranded with a dead battery. Not to mention, it disturbed our neighbors when this occurred in the middle of the night. This is a known issue with various Honda vehicles from this timeframe. It is know as a problem with the "Remote Access Control Module," aka the "Keyless Access Control Unit," located behind the glovebox. Even though it is a known issue, Honda was unwilling to repair it at their own cost. We paid $903.22 to get it fixed.

This complaint is being filed regarding a FAILED REMEDY for NHTSA Safety Recall 23V-431 (Honda Campaign ZEM) on my 2021 Honda Pilot Touring. Although the vehicle history shows that the recall repair for the MOST fiber-optic wire harness was previously performed, the authorized remedy has completely failed to fix the safety defect. The central infotainment dashboard screen regularly displays a "Network Connection Lost" error message before freezing or shutting down entirely. This failure causes an immediate, total, and unpredictable loss of the backup camera display while the vehicle is in operation. Because the backup camera is a federally mandated safety feature, its random failure creates an active safety risk for myself, my passengers, and pedestrians during reversing maneuvers. Honda customer service has refused to provide further diagnostic or repair assistance because the recall is already marked as "completed" in their database. However, the safety hazard remains active and unresolved. I request that the NHTSA investigate this failed remedy and compel Honda to provide an effective, lasting repair for this defective system.

My vehicle's auto idle engine stops when brake is engaged, goes into neutral when released instead of restarting causing me to have to turn on the flashers, shift into park, turn off the ignition then restart. I was almost rear ended at an intersection & held up traffic during another occurrence, causing impatience behind me. I then found numerous complaints on the same by Honda owners & extended 10-year warranty via service bulletins 23-008 & 23-009. I brought my vehicle into the dealership to be diagnosed on 9/29/26, & they said it needed the referenced valve adjustment & performed it. A few days later, on 10/4/26, it happened again in a grocery store parking lot as I stopped for a vehicle pulling out of space. I called the next morning & made the appt to have the starter diagnosed later in the week. Later that day, it happened again at a red light. I brought it back to the dealership on 10/9/26 & advisor called a few hours later to say said the starter was pulling too much power & causing the problem & needed replacement, but did not have it in stock, with no expected date, but would contact me as soon as they received it. About an hour later, he called back & said he was sorry to inform me that the starter was NOT covered under the 10-year ext. warranty for my VIN, just the valve adjustment (which did not resolve the issue) even though the tech said the starter pulling too much power was causing the problem. I was then provided a $1200 estimate- for a malfunction that is

The electrical for the infotainment system cuts out and the rear camera is no longer on the screen, it will cause loud popping while driving as the MOST Net system is failing. There is also poor gas mileage and reads the gas tank contents incorrectly while displaying incorrect MPG typical with the fuel pump recall for this generation of Honda Pilot, but both of these recalls removed my specific year shortly after they were announced.

Airbag Failure Report – 2021 Honda Pilot (Incident Date: April 10, 2026) I am reporting a critical failure of the supplemental restraint system (SRS) in my 2021 Honda Pilot. On April 10, 2026, while traveling at approximately 40–45 mph, our vehicle was struck on the driver’s side by a white commercial van. The severe impact caused over $9,000 in structural damage—including the driver-side door, fender, wheel, mirror, and radiator support brackets—yet the side/curtain airbags failed to deploy. As a result of this failure to protect occupants during a significant collision, the driver sustained permanent, non-repairable neck trauma (aggravating a prior surgical site), and the passenger sustained newly diagnosed bulging cervical discs. I request that this failure be documented and investigated as a potential safety defect.

Vehicle: 2021 Honda Pilot NHTSA Recall: 26V-365 Honda Recall: AOU Recall Status: Incomplete/Unrepaire I am submitting this complaint regarding a serious motor vehicle accident involving my 2021 Honda Pilot. At the time of the accident, my vehicle had an open and unrepaired safety recall, NHTSA Recall 26V-365, Honda Recall AOU. I was driving my Honda Pilot downhill when the vehicle began gaining speed in a manner that felt abnormal and uncontrollable. I attempted to slow and stop the vehicle by applying the brakes, but I was unable to stop the vehicle. Despite my efforts to brake, the vehicle continued moving forward and I ultimately collided with another vehicle, resulting in a multi-vehicle accident involving approximately three to four vehicles. The collision was severe. The front of my Honda Pilot sustained extensive damage and the airbags deployed. The vehicle has not been repaired since the accident and remains in its post-collision condition. After the accident, I checked my VIN through the NHTSA recall system and discovered that my vehicle has an incomplete safety recall, NHTSA Recall 26V-365. The recall concerns corrosion at the rear subframe suspension mounting points, which may result in failure of rear suspension components and adversely affect vehicle handling and control. I am concerned that a mechanical or vehicle safety defect may have contributed to my inability to slow or stop the vehicle. I am not stating that the recall definitively caused the accident beca

While driving with my family in my 2021 Pilot on the interstate at 75mph, I felt a shudder while in traffic. Fortunately, I signaled to get over and cars around me responded, because the check engine light flashed on and off and the car shut off. We had enough time to roll to the side of the interstate safely because drivers around me were aware and considerate. The car would not restart so we had to tow it. The Pilot has been evaluated by an independent mechanic who says that a failure in the high pressure fuel pump caused oil to dilute gasoline. A full engine replacement is required. There was no prior warning of this issue. American Honda has been contacted for potential support. Early stage of that, but dealing with them has, so far, been great.

Multiple times, when stopped (i.e., red light) and auto-idle engaged, the car has not come out of auto engine stop, but instead has shifted into neutral upon releasing the brake pedal. Furthermore, the car cannot be put into drive from that state, but instead must be fully turned off, and then restarted, often after a pause, and a cranking challenge. Car has a new battery (8 months old) and weather is mild/warm. This problem is unpredictable, and has happened in busy traffic situations, resulting in both a personal and physical safety issue.

When the brake is pressed at a light or when idling, the gear shifts automatically to neutral and will not drive. I have to press and hold the power button to restart the car. It is happening more frequently. I have taken it to the dealership several times and they have not been able to replicate it. It also doesn’t give any codes. This is a true safety concern because I have impeded traffic multiple times when it occurs. I tried to add pictures of the invoices that I received from the dealership but was unsuccessful.

The entire ADAS suddenly failed. the vehicle started cycling through all warning indicators (adaptive cruise control problem, abs problem, lane keep assist problem, brake mitigation system problem etc) brought it to Honda today and they confirmed that the "multi purpose camera/millimeter wave radar unit with aiming" had failed and needed to be replaced. Honda charged $1764.14 for all work to fix this on 9/15/2026

The contact owns a 2021 Honda Pilot. The contact stated that the vehicle was repaired under an unknown recall; however, the recall repair failed to prevent the failure. The contact stated that while shifting in reverse(R), the rear-view camera failed to display a clear image. The local dealer was contacted. The manufacturer was made aware of the failure. The failure mileage was approximately 75,000.

Our pilot is experiencing similar issues found online with catastrophic engine failure due to a misfire caused by a knocking rod. Honda so far has not responded to our claim despite it being a known issue around the same time ours was manufactured.

I am filing this complaint regarding a recurring “Network Communication Lost” issue with my Honda Pilot. I am aware that Honda has issued a recall related to network communication issues; however, when I checked my vehicle’s VIN, it is not included in the recall. My vehicle is experiencing the same network communication problem described in the recall. I am concerned that my vehicle may have the same underlying defect but is not currently covered by the recall. I believe this issue should be investigated because a loss of communication between vehicle systems can potentially affect the operation, reliability, and safety of the vehicle. I should not have to wait until my vehicle experiences a more serious failure before this issue is addressed. I am requesting that NHTSA investigate whether the recall should be expanded to include additional Honda Pilot vehicles, including vehicles with VINs that are currently excluded but are experiencing the same defect. I would also like this complaint documented as part of any investigation into Honda’s network communication system issue and any related safety defects.

Vehicle has multiple safety system failures. After extensive online research and multiple diagnostics, repair technicians indicating safety camera failure due to heat. Technician indicating significant increase specific to this vehicle of late. Excessive environmental temperature “frying” ADAS camera. This causes failure to HondaSense safety features such as collision mitigation, lane keeping, and road departure mitigation - features touted as industry leading by Honda. Matter has been diagnosed and duplicated by service technicians. Extensive online research indicates potential widespread issue that requires highly expensive replacement/repair and calibration.

Multiple times at a stoplight, car switched into Neutral I have to turn on my hazard lights, turn off the car and restart it

The contact owns a 2021 Honda Pilot. The contact received notifications of NHTSA Campaign Number: 26V365000 (STRUCTURE, SUSPENSION) and 24V064000(AIR BAGS); however, the parts to do the recall repairs were not yet available. The local dealer was contacted and confirmed that parts were not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure.

Front safety camera no longer works which has disabled the lane keep assist, automatic cruise control, brake system, and road departure mitigation system. This is a safety hazard.

Warning lamps for lkas, acc, auto lights and brake system started to appear. Honda diagnostics have pointed to an electrical failure with the multipurpose camera. The Honda representative admitted that this is a very common failure. I was told the car is “safe to drive” but there are constant brake system warning lights flashing on my dash. The net result is that I have no ability to know whether there is an actual brake system failure if one were to occur.

On at least 5 occasions this vehicle has gone completely dead as slowing down to stop or being completely stopped. Nothing electrical is available. No tail lights, headlights, or emergency flashers. After a long waiting period it has suddenly re-energized so far. This was purchased as Certified Honda used car and never serviced anywhere but a Honda delaership. They allegedly replaced the start/stop system under "extended warranty". The occurence is random. The dealership pushes back on taking any action because they can't repeat the problem on the spot. The car has staranded us at very major interesections twice and had to be towed. The risk driving this car is unacceptably high. We have video evidence of the failure. There may be a police report as we called them to control traffic.

My 2021 Honda Pilot has repeatedly failed to restart after the Auto Idle Stop system shuts the engine off while the vehicle is stopped. When the system activates, the engine can fail to restart when I need to move, leaving the vehicle stalled in active traffic. This has happened multiple times and creates a serious safety risk, particularly at busy intersections. Honda previously performed the software update intended to address the Auto Idle Stop failure-to-restart condition, but the problem continued after the update. I brought the vehicle to an authorized Honda dealership because the problem persisted. The dealership has now diagnosed the starter as the cause of the failure-to-restart problem and recommended starter replacement. The vehicle and affected components are available for inspection. Honda has acknowledged Auto Idle Stop failure-to-restart problems on Honda Pilots and has extended warranty coverage for starter replacement on certain affected vehicles. However, American Honda has informed me that my specific vehicle is not included in the starter warranty extension, despite experiencing the same failure-to-restart condition, despite Honda's software update failing to correct it, and despite the Honda dealer diagnosing the starter as the cause. American Honda is considering partial goodwill assistance toward the starter repair but has told me that the repair will not be covered at 100%. I am reporting this because the Auto Idle Stop system can intentionally shut of

The infotainment system and rearview backup camera malfunction continually. While driving or attempting to reverse, the infotainment system frequently shuts off entirely and loses its fiber optic network connection. When it attempts to reboot and turn back on, loud popping and crackling noises emit from the vehicle speakers. Additionally, the backup camera regularly glitches and displays a message stating that the system is "Too Hot," causing the rearview monitor to go entirely blank. These issues are especially severe on hot days.This creates an immediate safety hazard, as it unexpectedly eliminates rear visibility while backing up, increasing the risk of a collision. It also causes distracted driving conditions due to the sudden, loud audio popping and screen blackouts. This failure mimics the exact symptoms outlined in Honda's active MOST Bus Coaxial Cable recall, yet my vehicle is experiencing the same severe safety defects. Rear view camera does warn it no longer works due to heat. No inspection done as of yet but plan on taking it to dealership.

Was driving vehicle and all of a sudden engine light pops up with no driver codes and the left side of engine starts knocking. I pull into the closest shop. They test a vehicle misfire in cylinder 5 and propose vehicle gets towed to dealership to look at codes. I tow vehicle to dealership for them to tell me rod bearings, crankshaft are bad and need a new engine. Engine was 99k and well maintained with every service record included. I asked about Honda goodwill which they denied me due to vehicle not getting serviced at Honda for oil changes. The rod bearings were recalled on previous Honda models and there is currently an open investigation on 2021 models but no official recall.

The vehicle won't start, electrical system failure. Sometimes the electrical system fails when the car is driving/it will stall on the road. It was predicated by the alarm going off intermittently and without provocation (in the middle of the night/etc).

I am reporting a catastrophic engine failure involving my 2021 Honda Pilot equipped with the 3.5L V6 engine. The vehicle has approximately 77,000 miles. The vehicle developed an engine rattling noise followed by complete engine failure and loss of motive power. I had the vehicle transported to an authorized Honda dealership for diagnosis. Following inspection and engine teardown, the Honda dealer documented a hole in the front side of the short block, a large amount of metal debris in the oil pan, and the cylinder #3 connecting rod broken in half. The dealer concluded that the engine experienced catastrophic internal failure with widespread metal contamination throughout the lower and upper engine components. Due to the extent of the damage, the Honda dealer recommended replacement of the short-block assembly, both complete cylinder heads, fuel injectors and associated components. The estimated engine repair alone is approximately $20,275. I am concerned that this failure may represent a safety-related engine defect because catastrophic connecting-rod failure can result in sudden loss of motive power. Honda has previously recalled certain vehicles equipped with 3.5L V6 engines for connecting-rod-bearing failures that can cause engine damage, engine failure and loss of motive power. My 2021 Pilot is not currently included in that recall population. I am not asserting that the cause of my engine failure has been established as identical to the existing recall defect. However, g

#1 connecting rod bearing failure at 89,000 miles, all oil changes were done timely and properly. Car is very well maintained. While engine is running it has a very loud rod knock coming from bottom of engine. I did some research and it’s the same symptoms and issues as (NHTSA Campaign 23V751) 2016-2020 Honda pilot recall.

My 2021 Honda Pilot displayed a U3000 diagnostic trouble code, indicating an internal electronic failure of the front-facing multipurpose camera that operates the vehicle's Honda Sensing safety systems (Collision Mitigation Braking System, Lane Keeping Assist System, Road Departure Mitigation, and Adaptive Cruise Control). As a result, these safety systems became inoperative. I took the vehicle to an authorized Honda dealer, who confirmed the U3000 code and quoted approximately $2,000 to replace the camera unit. I have since learned this is a widely reported failure across multiple Honda and Acura models (Pilot, Odyssey, CR-V, Accord, Civic, HR-V, Clarity, RDX, MDX) and is the subject of a proposed class action lawsuit alleging Honda knew of the defect and failed to disclose it or issue a recall. I am filing this report to document the failure and its safety impact.

My 2021 Honda Pilot Touring intermittently fails to restart after the Auto Idle Stop system shuts off the engine at a stop. This occurs about 10% of the time. When I release the brake, the engine does not restart, creating a risk of being stranded in traffic. I must shift to Park and press the Start button to restart it. No warning lights or messages were observed. The problem has not yet been inspected by a dealer. The vehicle is available for inspection. Scheduled appointment at Honda service.

Ive had about 5 times my car Honda pilot 2021 stall at a stop light, a stop sign. The first it took a minute to go and the light was green. I was honked at and yelled at. It finally kicked on and we went, the next time it went into accessory mode at a stop sign, then into N then off…. All while in drive to start. The rest were times I was in auto start stop and it just wouldn’t start. Each 5 times it gave an error code that disappeared right after I had to try snd restart by pushing the button. I went to Honda 2 times now, first time they said they did the program… that didn’t stop the issue, I then took it again after the 4th time and they said it was a bad battery… replaced it mind you $400 later… and it did it the next day.. they won’t cover a free inspection and when I said there’s a bulletin about this they said they did id already but still doing it. I am very frustrated and j drive 3 kids under 7 this is very very unsafe especially someone who already has a brain injury from aka c I dent.

The vehicle’s driver‑assist and collision‑avoidance systems began failing simultaneously. Multiple warnings appear on the dashboard every time the vehicle is started, and the cruise control system has stopped functioning entirely. Adaptive Cruise Control cannot be disabled, preventing the use of standard cruise control. Collision Mitigation System Problem Adaptive Cruise Control Problem (ACC) Lane Keeping Assist Problem (LKAS) Road Departure Mitigation System Problem Auto High-Beam Problem The failure of one component impacts multiple vehicle features, the ability to maintain safe following distance, avoid collisions, stay within lane boundaries, and properly manage headlights. The loss of cruise control functionality also affects long‑distance driving safety and consistency. These systems are designed to prevent accidents; their simultaneous failure represents a significant safety hazard. Dealer inspection indicates repairs costing thousands of dollars, often involving replacement of sensors, radar units, or wiring harnesses. No recall or service bulletin has been provided to address this widespread issue. Many Honda owners have reported identical failures on online forums and owner groups. The pattern suggests a systemic defect affecting Honda’s driver‑assist safety systems across multiple models and years. I am requesting that NHTSA investigate this issue as a potential safety defect affecting Honda vehicles. The failure of multiple collision‑avoidance and lane‑keeping sys

My Honda has recently began displaying ADAS Failure where none of the features work including cruise control. I took to a mechanic and they displayed code U3000. This seems to be a common issue that Honda is not addressing. The fee to repair is over $1500 and the car is less than 5 years old. This is a safety issue.

I am having these problems with my 2021 Honda Pilot Touring causing intermittent sudden braking. The dealership is quoting me a lot of money to fix them. Collision Mitigation System problem Road Departure Mitigation System Problem Auto High Beam Problem Lane Keep Assist Problem Adaptive Cruise Control Problem These problems should not be occurring to a an expensive vehicle worth over $45,000 for no reason. The dealership mentioned that they are caused by a failed battery fan.

When at a stop, the automatic idle stop shuts off the engine and doesn’t come back out of that to start back up. Have to put the car in park to restart. This is a major safety issue especially when vehicles are behind me beeping the horn. Happened on several occasions.

Since 2023, this car’s auto start/stop feature has malfunctioned. Honda keeps replacing the battery and saying nothing else is wrong. It has had 4 battery replacements since 2023. Now they are saying I need to replace the starter. I no longer use the start/stop feature, but if I forget and it engages, my car will not restart leaving me in an intersection trying to get the car to restart, which in a large city is scary. They did adjust the controls one time under an extended warranty, but it did not help. The service manager says nothing else can be done, but I’m reading this is an open investigation on this issue and Honda should be replacing the starter as well. My car has had all scheduled maintenance done at the dealership and only has around 56,000.

My current 2021 Honda Pilot (purchased used May 2024) is stalling out in live traffic - the most recent on XXX creating a massive safety hazard. (In addition, the engine is making the same exact clicking noise that the 2015 Honda VIN:[XXX] made right before the engine catastrophically seized on my way to work. That 2015 Honda Pilot seized due to a defective Variable Cynlinder Management (VCM) system. This defect was covered by a court-ordered federal class-action settlement warranty extension (Alex [XXX] v. American Honda, Case No. XXX), extending coverage to 10 years/150,000 miles. While that vehicle was fully within this window - Honda of [XXX] wrongfully denied this legal warranty.) The CURRENT 2021 Honda Pilot (Purchased Used) VIN: [XXX] suffers from intermittent engine stalling in live traffic. The dealership has failed to resolve this issue across three separate visits, while exploiting the emergencies. The timeline of failed repairs includes: 2/14/25: The vehicle stalled in live traffic. The dealership charged me $420.48 for diagnostics and a failed repair. 8/13/25: The dashboard lit up and the vehicle suffered engine failure leaving my family stranded for 9 hours waiting for Honda Assist. It was brought to the Honda of New Rochelle service center where they exploited this emergency to charge me an exorbitant $1,300.00 out of pocket for unrelated work financed via Sunbit loan. 9/24/2025: The vehicle stalled in live traffic for a third time. The dealership charged me an

Vehicle stalls when the car shuts off from the auto engine idle shut off feature. The concern was allegedly resolved twice with an update but the issue persists. My battery died in December 2025, when asked if it was a result of the recall causing repeated start failures, the dealership denied. Recently my vehicle shut off from the auto engine idle stop feature and completely died, I had to push to start my vehicle several times to start it back up and this was after replacing my battery 7 months ago. A heavy duty battery was purchase to meet my vehicle needs.

While driving down the road the emergency braking turned on many times when I wasn’t even near a vehicle. It turned on about a total of 10 times without a car being unsafely in front of me. I just got this vehicle today and I’m worried about whether I should keep it or not because of this.

My 2021 Honda Pilot has a recurring electrical/network communication failure that causes “Network Communication Lost” and “MOST Net Off” messages to appear on the infotainment screen. When this occurs, the infotainment system malfunctions, audio becomes unavailable, and the backup camera display is lost without warning. The problem is intermittent, unpredictable, and has occurred numerous times. The loss of the backup camera is a serious safety concern because it occurs while the vehicle is otherwise operating normally. During reversing, rear visibility is reduced, increasing the risk of striking another vehicle, pedestrian, child, cyclist, or object. The error messages and loss of infotainment functions also create driver distraction and raise concerns about the reliability of the vehicle’s electronic systems. I reported the issue to an authorized Honda dealership multiple times. They recommended replacement of the audio/display unit, and I paid for the repair. However, the same failure returned. The dealer later advised that the root cause may involve wiring, MOST network components, or another electrical defect and estimated approximately $3,000 in additional repairs. Despite multiple visits and approximately $983.29 in diagnostic and repair costs, the defect remains unresolved. Honda Service Bulletin 20-058 describes similar MOST bus symptoms, including communication errors, loss of audio, infotainment malfunctions, and multimedia network failures. My vehicle exhibits the

My 2021 Honda Pilot has a failing rearview camera caused by the identical MOST network coaxial defect described in NHTSA Campaign 23V431000, but Honda drew the recall population too narrowly and excluded my VIN.

The car shut off and put itself in neutral in the middle of the road. It seemed that the automatic shutoff glitched and caused the car to shift to neutral. We had to shut it off then start it back. It didn’t start right up. We had to try a couple of times. It was very scary being stranded in the middle of the road and not knowing how to correct the problem.
