Electrical System Problems of Honda Passport - part 1

The improperly designed or manufactured most coaxial cable can deform its terminals. This leads to intermittent connection losses between the audio display unit and the vehicle cable connector. If connection loss lasts for more than 20 seconds while the vehicle is in reverse, the rearview camera image fails to display. This increases the risk of a crash or injury. Honda issued a recall notice to replace with a new harness. The replacement did not fix the underlying problem. Our vehicle was “repaired” under the recall but the problem persisted. We were told by our local Honda dealership that we would need to replace the entire av system to remediate the issue. We paid to have that work done, and the issue has started again. The dealership called Honda to consult with its technicians and they say that the issue is caused by the replacement harness. The work completed under the recall did not remediate the underlying safety issue, we paid thousands of dollars to try to fix it, and are now being told we would have to pay $5000 to repair a manufacturing defect.

This is the third time that the auto idle engine has caused an issue while driving. If I attempt to turn the system off at a stop light it will automatically force my car into neutral and will not allow me to put my car back into drive. I have to turn the car off completely which it also does not allow easily and takes several attempts while I’m sitting in the middle of the road with my hazards on and praying I don’t get rear ended! once I finally get the car to turn off it then allows me to restart and drive again. This should not be happening and is very unsafe yet when I took it into Honda they couldn’t replicate the issue so they said they couldn’t fix it even though it is a very common and known problem with the auto idle engine!.

My 2021 Honda Passport experiences a sudden, complete failure of the digital instrument cluster and infotainment screen while driving. The dashboard controls go pitch black without warning, resulting in an immediate and dangerous loss of the speedometer, critical vehicle safety warnings, and the federally mandated rearview backup camera. The system stays dark for 3 to 4 minutes before attempting a forced system reboot. This matches the exact failure mode of NHTSA recall 23v-431 (most bus network connectors). However, both the dealership and american Honda corporate refuse to cover the repair, stating my specific VIN is excluded from the current recall footprint. This is a severe, active driving hazard that removes critical speed and safety information while traveling at highway speeds.

The contact owns a 2025 Honda Passport. The contact stated that while stopped at a stoplight, the contact attempted to accelerate; however, the start/stop system failed to restart the engine. The check engine warning light illuminated, and there was an alarm sounded. The message "shift to park" was displayed; but the gear shifter failed to shift into park. The brake pedal was depressed with excessive force and waited for a while before the vehicle was shifted into drive and the vehicle was driven forward. The vehicle was driven to the desired destination and shifted into park. The dealer was contacted and an appointment was scheduled. The failure mileage was 30,600.

Driving from [xxx] to [xxx], just over 1hr into trip @ 100 miles out of town and on one of the many steep inclines on the route, the engine power seemed to pulse, as if increase and decrease of gas/acceleration, then has every single alert possible illuminated on dash with the bell sound: electric power steering system problem, steering assist reduced. Electric parking brake system problem, parking brake not available. Brake system problem, brake performance may be reduced. Brake hold system problem, apply brake when stopped. Vehicle stability assist system problem, reduced traction and handling. Trailer stability assist system problem. Hill descent control system problem, apply brake when descending. Hill start assist problem, vehicle may roll upon brake release. Adaptive cruise control system problem. Collision mitigation braking system problem. Road departure mitigation system problem. Low speed braking control problem. Emission system problem, avoid heavy acceleration and high speed. All wheel drive system problem, only front wheels may be powered. All alerts ending with 'see your dealer' the car then had reduced power which was a significant safety concern and driving risk when navigating hills and traffic flowing at 75mph uphill while this vehicle going slower and slower regardless of gas pedal pressure: 65mph, than 60mph, than 55mph, than 50mhp eating gas like crazy. Coasted into gas station to asses. At low speed there was a rattle upon pressing gas pedal coming from under the hood. The vehicle is 3 months old and has 4,197 miles. It is not simply that the alerts illuminated, those systems were all affected: braking, steering, acceleration, lane departure, cruise control etc. All were not working. Heavy acceleration and high speed were not even an option. Somehow made it back to [xxx] in limp/aux mode. Dealer has had vehicle for 6 hours and no update other than, 'it's not the battery' information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I have a 2025 Honda Passport with approximately 22,776 miles. Over the past several weeks, the vehicle has developed a progressively worsening starting problem that appears to be heat-related. After the vehicle is driven normally and reaches full operating temperature, then is shut off and allowed to sit for approximately 10 to 30 minutes, the engine will sometimes crank very slowly and sound as though the starter is laboring to turn the engine. The frequency and severity have increased over time. On two recent occasions, the engine barely turned over before starting. After the vehicle sits overnight and cools completely, it starts normally and cranks smoothly. A second related problem occurs when the auto idle stop/start system is active. Both my wife and I have experienced very slow restarts at stoplights. More recently, the engine failed to restart automatically after auto idle stop shut the engine off. I had to shift the vehicle into park and press the engine start/stop button multiple times before the engine finally turned over and restarted. This created a safety concern because the vehicle was temporarily unable to move while stopped in traffic. The vehicle was taken to an authorized Honda dealer for three full working days. The dealer reported that the battery, alternator, starter, charging system, and starting system all tested normal, and no diagnostic trouble codes were present. However, the dealer’s written repair description does not state that the vehicle was road-tested and then allowed to sit through the 10–30 minute hot-soak period that consistently produces the problem. The dealer stated that they allowed the vehicle to idle for an extended period and performed multiple starts, but this did not reproduce the conditions under which the problem occurs. I also opened a case with american Honda. Honda advised that they would not escalate the issue to engineering until the vehicle had been returned to the dealer one or two additional times. The probl.

This is a failure of 2019-2020 Passport pilot most bus network recall of 2021. My Passport was serviced for 23-047 1923 fakra service cables at most bus network on October 26, 2023. The system has failed again. The most system has popping, crackling and then goes out. Takes several minutes to recover. Presents the same safety hazard as the original recall I have video which I will show to the dealer on Thursday September 10, 2026.

I own a 2020 Honda Passport elite with approximately 63,000 miles. The infotainment display intermittently goes completely black while driving. When this occurs, the rearview camera also becomes unavailable. I have also experienced crackling or electrical-type noise through the speakers during the problem. The problem is intermittent. The system may operate normally for an extended period and then suddenly fail. On several occasions, the display went black, returned to normal, and then went black again several times while driving. After the vehicle was stopped and later restarted, the system returned to normal operation. This is a safety concern because the rearview camera can become unavailable, particularly when the vehicle is being operated normally and the driver cannot predict when the failure will occur. Honda safety recall 23-047 was previously performed on this vehicle. I contacted american Honda customer service, and Honda's records show that the recall repair was completed on June 30, 2023. Honda currently shows no open recall or warranty coverage for this problem. The symptoms I am now experiencing are similar to those associated with the most bus/fakra connector problem addressed by Honda, including display problems, audio problems and intermittent or blank rearview-camera operation. The vehicle has not yet been diagnosed or repaired for this current occurrence. I am requesting that NHTSA review this complaint to determine whether this may represent a recurring safety-related defect after the previous recall repair and whether further investigation or action by Honda is warranted.

Vehicle has excessive battery drain at times. Auto start-stop causes car to stop in traffic and difficult to restart. The original battery was replaced at 3 1/2 years of age. The replacement battery failed after about 2 years of service and replaced under warranty. That battery has now failed again. The car is a little over 6 years old and by all rights should only now need a replacement battery. I suspect parasitic drain problem but the dealer has only replaced the battery and no other parts I'm aware of.

The auto idle stop feature failed to restart the car after sitting at a stoplight twice this past week. The dealer (frank leta hoda) diagnosed the problem as a "bad starter". I believe this falls under the active investigation ea22005 - no start after auto start/stop engages. The vehicle is two years old with 40,378 miles at the time of reporting the problem to the dealer. I reported this to Honda corp and was assigned case number 16619534 which is being reviewed. The two incidents happened without warning during drives when I had already pushed the button to disengage the auto idle stop feature and was not expecting the engine to turn off at all.

“idle-stop” feature stays on per factory installation. However when car is stopped and brake is released to proceed with acceleration, the feature automatically throws the transmission into “neutral” and will not go forward, allow shifting of gears or shutting down the engine. This has happened numerous times in heavy traffic and creates a hazard. There is a button to depress to shut off the idle-stop but it must be done every time the car ignition is shut off then on. This is not a normal habit of long term drivers. After two inspections at the dealer and several phone calls Honda says they can not replicate the problem when serviced thus offering no solution. Searches online for assistance has revealed that this is a highly prevalent problem with Honda and Acura vehicles since 2019. As an elderly (over 75) driver with an excellent driving record it is creating a troublesome risk when driving.

The contact owns a 2019 Honda Passport. The contact stated that the infotainment system screen intermittently turned off while driving approximately 65-80 mph. The messages "network communication lost" and "most net off" were displayed. The failure caused the rear-view camera to become inoperable and the speakers to make crackling sounds, which distracted the driver. The contact stated that the vehicle was taken to the dealer and a second dealer, Honda of princeton (987 state rd, princeton, NJ 08540), where the fakra connector was replaced several times, but the failure persisted. The dealers attempted to repair the vehicle nine times over four years. The contact related the failure to warranty extension: 21-012 (2019-20 Passport/pilot most bus network connectors) and NHTSA campaign number: 23v431000 (back over prevention); however, the VIN was not included in the recall. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 62,000.

On August 14th I brought the vehicle to coconut point Honda after having the vehicle stall with the auto stop feature. At that time, I also noticed that the car had trouble starting at times. After being there for four days, I was asked to come pick up the vehicle. Yesterday, on August 27th, the vehicle stalled again, this time at a busy intersection. This narrowly missed causing my wife to get hit at high speeds. The car shifted itself to neutral, the battery and warning light came on, and a message saying “shift into park” appeared on the dash. Despite several attempts, the car would not restart until it finally sat a moment and then powered back on. The car was brought back to coconut point Honda where I again voiced the complaint and safety concerns regarding the vehicle stalling out and shifting itself into park.

2023 Honda Passport trailsport rear a/c is blowing warm air and will not get cold. If rear ac is not blowing any cold air than it will be sure that front ac will follow, this should be a manufacturer defect recall because there are many same model with the exact same problem.

Over the past two weeks we have been experiencing issues with the auto idle stop device on my 2025 Honda Passport. This has resulted in being temporarily stalled at several busy intersections. I have reported this issue to a Honda dealership where the issue was verified and it is scheduled for a starter replacement when the part is received from back order.

Automobile warnings include: "audio is turned off" "network communication lost" "most net off" loss of all audio, screen, and backup camera. Most common when starting the car or hitting imperfections along any roadway. I need all audio, screens, and backup cameras functioning completely and predictably to ensure safe driving. Vehicle was recalled twice already for most cable and audio defects. Dealership refused to investigate related issues on xxx. No follow-up after a call placed to Honda automobile customer service line [xxx] on xxx. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My car has 22,000 miles in it, and maybe around 19,000 miles my starter was already weak. I barely use my car, and one time I used it and my car won't start at all. I almost got stranded. Luckily it turned on, and I was near my house. This could've happen in the middle of nowhere and get me stranded. I don't feel safe driving this now if im not sure. I thought this was supposed to be a reliable car!.

There is a known issue with auto idle feature. If you do not manually turn off every time it stays on and occasionally will cause car issue when stopping. I have had it happen in vehicle about a dozen times. When you fully depress brake engine is suppose to I gel to save gas however on occasion the vehicle will completely stall out. I have had this issue happen when approaching stop signs or in traffic situations. The biggest problem is trying to reengage car. Sometimes you can feel it starting to do this and if you quickly apply gas you can avoid it however sometimes the car will lock up with display lights and you have to keep pushing the engine stop button to turn off the vehicle and turn vehicle back on. It is sometimes difficult to even turn off engine vehicle when this happens but seems to be only way to get vehicle to respond. I have had vehicles behind me almost hit me while I try to get vehicle out of this mode. I know it’s an issue as it’s all over the forums when you search for fix.

The car has failed to start on numerous occasions. The car has stalled due to the auto start/stop and the dealership told me that the battery needs to fail testing in order to replace under warranty. This is a major safety risk and the dealership said it’s a known issue but they can’t fix it. A recall needs to be put out immediately.

The starter motor on my 2022 Honda Passport failed, causing a complete 'no-restart' condition after entering auto idle-stop mode. The vehicle previously received the mandatory pgm-fi idle-stop software update under Honda service bulletin 23-008, proving that the software fix does not protect the hardware from failing. The dealership diagnosed a failed starter but stated that my 2022 model is excluded from the 10-year starter warranty extension under service bulletin 23-009, leaving me to pay out-of-pocket for a known defect. I am filing this to support the ongoing NHTSA engineering analysis regarding Honda auto idle-stop system failures, as the defect creates a dangerous stall risk at intersections.

My 2026 Honda Passport trailsport elite has twice applied its brakes on its own, with no obstacle, vehicle, or hazard in front of me to justify braking. On July 13, 2026, at approximately 5:36 p. M. , I was driving in evening traffic when the vehicle suddenly braked hard on its own. Nothing was in front of me. The car behind me nearly rear-ended me and had to brake sharply to avoid a collision, and the driver reacted with road rage. On July 16, 2026, at approximately 6:03 p. M. , my young son was in the vehicle with me. While I was driving in traffic, the vehicle again braked on its own with no obstacle ahead. A sedan behind me nearly rear-ended me. This sudden, uncommanded braking happens without warning while I am driving in traffic and has nearly caused a rear-end collision on both occasions. It is terrifying and I no longer feel safe driving this vehicle, especially with my child. The same vehicle also has ongoing electrical and drive-power failures (loss of power while driving, repeated stalling in reverse, and complete no-start events) that I have reported separately. Three dealerships have been unable to identify or correct the problems. No crash has occurred yet, but only because the drivers behind me reacted in time. The vehicle is available for inspection.

4th occurrence. Car fails to start. The instrument display reads: auto engine idle stop system problem. Electrical system including radio, a/c etc were working. (including the car alarm which begins honking the horn as soon as I open the door) repeated attempts to start the car failed to do anything except to annoy anyone within earshot as the horn kept honking! roadside assistance was not able to get the car started either so it was towed to the dealer. I've had the car into the Honda dealer for recalls but this problem has not been solved.

On July 11, 2026, while driving, the vehicle suddenly experienced multiple system failures. The dashboard illuminated with numerous warning lights, including a flashing check engine light, indicating multiple system malfunctions. The vehicle was towed to the dealer due to the severity of the issue. It is currently at the dealership for inspection and diagnosis. I have not yet received a diagnosis or confirmation of the failed component(s) from the dealer. No warning lights, messages, or symptoms appeared prior to the sudden failure. The abrupt illumination of multiple warning lights while driving created a significant safety concern regarding the reliability of critical vehicle systems.

For several months before the failure, the auto idle stop (engine stop-start) system became progressively slower to restart the engine after stopping. Each restart sounded sluggish, as though the starter was dragging, and the vehicle would remain stopped for several extra seconds before moving. This occurred repeatedly at traffic lights and other stops creating a safety concern as drivers behind me expected my vehicle to begin moving when traffic started. The unexpected delay increased the risk of being rear-ended or causing confusion in traffic. The failure eventually became complete. While stopped on a two-lane road waiting for another vehicle to turn left into a driveway, the engine shut off as expected with the auto idle stop system engaged but did not restart when I released the brake. Instead, the vehicle entered what appeared to be a neutral state and could not be driven. I was unable to restart the vehicle for several minutes, leaving it disabled in the travel lane while other vehicles had to drive around it. This created a safety hazard because the vehicle was stranded in an active roadway. The vehicle had not previously displayed any warning messages related to this condition. Looking back, the progressively slower and dragging engine restarts appear to have been warning signs before the complete failure to restart. The vehicle is scheduled for inspection the Honda dealership this week. The failed components should be available for inspection if requested.

The contact owns a 2025 Honda Passport. The contact stated that on several occasions, the auto start/stop intermittently failed to operate and the vehicle shut off while depressing the accelerator pedal. The contact stated that a battery warning light was displayed on the instrument panel. The contact was able to restart the vehicle. Due to the failure, the contact was forced to manually turn off the feature each time after starting the vehicle. Upon investigation, the contact's husband discovered NHTSA action number: ea25004; and associated the failure with the action number. The husband also associated the failure with the fuel injector or a possible software update. The vehicle was taken to the dealer; however, the failure could not be duplicated. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 15,800.

I drive the car with the engine-idle-at-stop function disengaged. Several times when slowing down, but still moving, the car shifts into park; the ac and radio remain on. I have to press engine start to start the engine. Several other times when already stopped, such as at a red light or in traffic, waiting to make a turn, the engine shuts off and the car shifts into park. I have to press the engine start button to turn the car back on. I am getting honked and hollered at in traffic, and could easily be vulnerable to being rear-ended when my moving car suddently turns off ad stops running (winds up in park). A non-dealer ran diagnostics and found no history of any error codes, and the system worked when they drove it. The day before the non-dealer had the car, it shut off 2 times in about 2 miles. He said the new battery is fine, the alternator is fine, and they do not know what to troubleshoot. No lights light up prior to the incidents, but they light up momentarily during it is the "charging system indicator" and the "malfunction indicator lamp" that light up. The new battery is one week old and installed as per the owner's manual and was checked by a 3rd party today. These events have occurred with both the original and new batteries. All of this has been over the past few months, with most incidents - an escalation - the past couple of weeks.

Got to red light, auto stop idled down car, when going to move car shut off and stalled out. Also happened two times in a drive thru. All times messages popped up auto stop interruption and vehicle in accessory mode.

While waiting at a stoplight, the car was in auto idle stop system mode. When the light turned green, I stepped on gas pedal and the vehicle shut off. The brake was hard and I could not turn off the vehicle for a minute. I opened the drivers side and passenger front door and closed, then was able to turn off vehicle. After a few seconds, I was able to start vehicle with push start button. The vehicle has sounded sluggish when starting up lately but battery tested good.

The contact owns a 2020 Honda Passport. The contact stated that upon starting the vehicle with the push-to-start feature, the adaptive cruise control, road departure mitigation, collision mitigation brake system, and lane keeping assist system, and the high beam messages were displayed on the instrument panel. An audible alarm sounded while the messages were displayed. The vehicle was taken to a local dealer, where it was diagnosed and determined that the multipurpose camera needed to be replaced. The vehicle was not repaired due to the cost, and because the parts were on back order. Upon further investigation, the contact stated that the windshield heat exposure might have caused the failure in the hotter weatehr. The manufacturer was not made aware of the failure. The failure mileage was approximately 94,078.

Car tried to start on its own, set off the alarm multiple times and killed a new battery after 6 months. Would not allow me to enter car by remote had to unplug battery. Issue with start/stop idle system, it is know issue with Honda ridgeline but having same issue with Passport.

Our 2026 Honda Passport tse suddenly stalled twice in active traffic intersections in albuquerque, nm under acceleration and during a left turn, causing a sudden loss of motive power and a severe safety hazard and a potentially life threatening situation. Telemetry logs from an aftermarket gps device installed in my vehicle captured a catastrophic voltage drop down to 10. 886v during the incident, which electrically blinded the ecu and prevented the vehicle from storing a diagnostic trouble code. The vehicle was taken to garcia Honda in albuquerque, nm who documented the symptoms ('loss of power on accel,' 'hesitates and jerks') but released the vehicle unfixed because no digital codes were present. The vehicle is currently grounded as unsafe to drive. American Honda corporate case number: [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Idle stop has failed to restart on more than once occasion. Battery tested low @ 25,000 miles.

The contact owns a 2022 Honda Passport . The vehicle auto start stop failed when at a traffic light. The vehicle was shut down and restarted and the vehicle was able to be driven again. In another occurrence, the vehicle stopped in the middle of the road at the stop light. After awhile, the vehicle was able to restart and drive without issues. The vehicle was taken to a dealer; however the vehicle was diagnosed with having a starter failure and burned out relay. The parts were repaired. The manufacturer was notified of the issue. The approximate failure mileage was 38,100.

I own a 2022 Honda Passport . The vehicle auto idle-stop system has failed to restart at a traffic light. The vehicle shuts down and eventually restarts after several manual attempts and was able to be driven again. Typically, the vehicle stops in the middle of the road at the stop light and the engine shuts down. After a while, I was able to restart and drive without issues. In the meantime I am in a stalled vehicle in the middle of high speed traffic. The vehicle was taken to a dealer. The vehicle was diagnosed with having a starter failure and two burned out relays. I have never had a problem starting the vehicle when I begin a drive. The parts were repaired. The manufacturer was notified of the issue. The approximate failure mileage was 38,100. Failed parts were retained by the dealer.

My 2026 Honda Passport trailsport elite (purchased new may 2025) has repeated, intermittent failures of the electrical system and drive-power (propulsion) function, beginning at ~16,700 miles. Severe symptoms first appeared in may 2026: multiple dashboard warning lights and error messages illuminating at once, and the instrument panel cutting in and out while driving. Sometimes a cascade of warnings precedes a failure; at other times the vehicle loses power or stalls with no warning at all. On July 4, 2026, the vehicle lost all drive power and shut down while I was driving ~75 mph on the highway, creating a substantial risk of a collision and of being struck by surrounding traffic. On four occasions (5/15/26, 5/22/26, 5/31/26, 7/9/26) it stalled immediately after being shifted into reverse. On multiple occasions it failed to start or had no electrical power, stranding me while traveling with my children. Additional failures: the driver's door intermittently will not lock or unlock, the exterior mirrors fail to fold and must be moved by hand, and the seat memory resets without input. Because the failures are intermittent, neither dealer could reproduce the condition on demand. The waco, TX dealer (6/1/26) could not duplicate the concern and performed no repair. The lufkin, TX dealer (6/8/26) said it could find nothing wrong, replaced the battery, and the failures continued unchanged. No specific failed component has been identified. The vehicle has been inspected only by Honda's authorized dealers. It has not been inspected by police, insurance, or an independent service center, as no crash has occurred. No crash or injury has occurred, but a vehicle that loses power at highway speed and stalls in reverse creates a substantial crash risk. The vehicle is in my possession and available for inspection upon request, along with video of several failures and dealership repair records.
