The auto idle stop failed to restart at a traffic light. This happened at a busy intersection in heavy traffic. The date given below is the most recent incident; it has happened twice now. Usually I try to remember to disable the idle stop feature, but this time I forgot, and it failed. The first time it happened was November 2024.

At a red light in an intereection the auto engine idle stopper feature stopped the engine and it failed to power / restart the engine. The cars electral system locked up. Could not restart engine, and could not put car in neutral because engine needs to be on. Had to car battery jumped. Took car to Honda dealership after incident. They concluded that the battery and electrical systems passed all diagnostic tests. If this is the case there is a major safety issue with the car.

The Passport is equipped with an auto stop/start engine feature. In the last week, while stopped in traffic in the roadway the engine shut off, but did not turn back on causing the car to stall in traffic for several minutes before I was able to restart it. The vehicle shifted to neutral and wouldn't restart until the power was fully off and the door was opened and closed. Both times I was stuck in a travel lanes for approximately 3-5 minutes.

On 4-5 occasions, the auto shutoff system will shut the vehicle down at a stop light when the brake is depressed. The vehicle did not restart as normal. In order to get the vehicle to restart, the vehicle has to be turned completely off and allowed to sit for 1 minute. The battery was fully charged and less than 1 yr old. The dealer was asked and did not find any problems and could not determine a cause. As a retired couple, this is quite concerning especially when in a major city, fully stopped and unable to get the car moving. The other drivers get upset and angry, which is scary these days. I am concerned that the auto shutoff might engage in heavy interstate stop and go traffic, which could lead to a major highway crash. Interestingly, I just received a note from a law firm filing a class action suit against Honda, if repairs were made. So, clearly there is a defect in the auto shut off system which need to be addressed.

The auto idle stop, turned off the car at a busy intersection, I was able to restart the car and took it in to the dealer. They installed a new battery, which has been working for about a year, then yesterday the ais caused the car to stop again at a stop light and again today when I was waiting to make a left turn. Each time it has stopped it has taken longer to get the car to restart. This is a very scary situation when driving in traffic with my grandchild in the car. It seems unlikely that I need another new battery. The car only has 55,000 miles. I will be taking the car in again, but doing my research on this issue I find it is a very big problem with this model of car, so I wanted to add my issues to the count, so hopefully something will be done to solve the problem before there is a major crash.

First issue was I was in need of a transmission while only having the car for 1. 5 years. I reached out to Honda corporate and I was unable to receive any help with goodwill. Secondly I am now experiencing issues with my alarm going off suddenly, and frequently. The dash board lights up and flickers. Upon doing research I have found that 2019 Honda Passport has had major issues with transmissions, keyless modules controls and electronic issues. In addition my radio keeps going off and it says connection is lost. This has also been a very known and common issues upon doing research on the 2019 Honda Passport there’s different dates for events. I will be able to email my invoice for my transmission.

Owned the 2021 Honda Passport for 4 years and have had multiple issues over that time. 1st. Electrical issues. Randomly while driving the center/head unit will continuously restart on a loop until vehicle is turned off and turned back on. 2nd. The speakers make crackling noises randomly while driving. Even when the audio/speakers are turned off the crackling continues. (very loud and annoying) 3rd. The Passport sometimes shuts off completely when stopped at red lights and has difficultly turning back on / restarting. This showed an error that there was a battery issue, which the battery had just been replaced a month or two earlier. It said something about being in accessory mode. 4th. The sensor that tracks oncoming traffic goes off sporadically. There are times on single lane roads that the car forces the breaks on because it senses cars on the other side. 5th. There has been issues while accelerating that feel like the car is having trouble shifting. It continues to rev but not go, when letting off the gas it almost feels like its doing an engine break to get back down to a certain rpm or something. Had the whole car bouncing, had to pull over and turn off the car to get it to start working properly. *** all of that said, this car has been and continues to feel unsafe to drive for multiple reasons listed above. I'd be more than happy to go into more detail for them if needed. ***.

Hello, I have put 3 batteries in this vehicle so far and it is a 2019 model year. In April, the car died while my wife was stopped at a light in the middle of town. I could not do anything. . . Put it in gear. . Nothing. . . Could not even open the door locks. I had to crawl into the back of the vehicle over the seats to get to the booster cable in very rear of the car. I was able to boost the battery and get it started after watching 100's of cars drive directly by me and around me while the car was stuck. It was a little dangerous. An automotive shop replaced the battery. The manufacture date on the battery is 2/25. My wife went the start the vehicle today. . . 6-19-25 and the battery was dead again. There is something wrong here! I looked at the website for recalls and the only thing that comes up is the fuel pump recall which I tried to schedule several months ago and they did not have the part. Please make Honda expand this recall and make them responsible for this problem until we are sure it is fixed. This really should be covered at no cost. Thank you!

Today, while backing from my driveway into our residential street, I came to a complete stop and placed the vehicle's transmission from reverse to drive and when doing so, the vehicle shut itself off, put itself into park and engaged the parking brake. I was able to re-start the vehicle and it operated as usual. We have an appointment scheduled with our local Honda dealership on 05/19/25 to inspect the vehicle.

The navigation when using apple maps simultaneously tells the driver 2 different sets of directions that do not match. The small screen on the gauge cluster shows incorrect street names that are nowhere near your location, and also tells you incorrect turns. For example, the large navigation screen on the infotainment system will say to make a right turn on the correct street, while the small screen on the gauge cluster will tell the driver to make a left turn an a different street that that the vehicle is not near. Sometimes it will make up random street names. This is dangerous to drivers who are not aware of the problem or forget about it because it causes confusion while driving. This causes the driver to wonder which set of directions to follow, make wrong turns, and look for streets that are not there. This would be especially dangerous to new drivers or elderly drivers. The vehicle was taken to 2 different dealerships for service but neither one of them were able to fix the problem. The dealerships have acknowledged the problem. There are no warnings or messages about the problem. The vehicle is available for inspection and the problem can be easily reproduced 100% of the time.

Auto has a known defect with headlight condensation ,Honda put out a bulletin sb 23-024 stating they are aware of this issue. Vehicle had this problem at 38000 miles just outside their standard 3 year 36000 mile warranty. To repair this Honda dealer stated a price of $1400. 00 ,which is a lot of money ,my concern is that failure to fix will lead to other headlight issues such as burned out bulbs and harness corrosion. Not to mention adding to dim light poor visibility.

On 11 Apr 2025, I was driving my 2023 Honda Passport at night on a toll road in clear weather when my infant son began screaming in distress. I pulled over onto the shoulder, partially onto a dirt area with bushes for more space. I pressed the “park” button, unbuckled my seatbelt, and opened the driver door to step out. As I did, the vehicle suddenly began rolling forward despite being in park with the door open and the seatbelt off. I fell trying to exit and had to roll away from the vehicle as it continued moving. A passenger jumped into the front seat and stopped it. This wasn’t a lurch or slight movement the car rolled enough to put me in danger. It behaved as if it were in neutral, not park. I later tested the same conditions (engine running, door open, seatbelt off), and the vehicle auto-shifted to park as designed. This confirms the safety feature failed in that moment. No warning lights, alerts, or error messages appeared before or during the incident. I reported the issue to Honda and asked the dealer to inspect the transmission and interlock systems. No faults or diagnostic codes were found. The service advisor said park can take a second to engage, but the movement I experienced was excessive and unsafe. This is a serious safety concern, especially with children in the car. I’ve also seen other reports of similar issues in Passport and pilot forums. I have manageable scrapes and a joint effusion in my knee.

The vehicle infotainment system froze. Several minutes later after driving, I pressed the brakes but they did not function. The vehicle would not stop and crashed into the vehicle in front of me. Emergency braking did not engage or otherwise show signs of activation. After turning off the car and dealing with the accident, I restarted the vehicle and the brakes and infotainment system operated normally.

Description: I have a concern that I will follow-up with a letter via usps. Imagine driving your 2019 Honda Passport on an interstate, speed limit is set at 70; your speed is 75; you're in the middle of the three lanes of travel; and your vehicle suddenly decelerates and every warning the vehicle is equipped with start giving alerts in rapid succession. This is what happened to me on [xxx] at approximately [xxx]. What is concerning is that this exact same thing happened April 2023 and I was told it was the idle control sensor. The dealership that sold me the vehicle was gracious enough to let me bring it to them for repair, without charging the full cost of the part but, labor cost I incurred. When a consumer purchases a vehicle, the second most expensive purchase in one's lifetime, it is implied that outside of normal and routine maintenance, the car has been assessed and inspected for drivability. Being that this is the second occurrence, I am questioning if this vehicle was thoroughly inspected for this issue? I had my vehicle towed to the greensboro Honda dealership, 3633 w. Wendover Ave. , greensboro nc 27407. Although my faith and loyalty to the Honda brand has diminished, the customer service provided by ms. Karen was comforting and reassuring. She understood my concerns and was phenomenal in letting me know what to expect. Surprising for a weekend as, most employees are not wanting to work. The reason for this email is two fold, notification of the issue and hoping that Honda will take accountability financially and resolve whatever "root" issue(s) that could be cause. Thank you and if my life has any significance to you, I hope to hear from you regarding this serious concern. Information redacted pursuant to the freedom of information act (foia), 5 u. S.

We are currently experiencing very cold weather in my area. I have a Honda Passport that uses a camera for its braking, lkas, acc, and other features. During extreme cold, the camera shorts out causing safety systems to fail. Others report the same issue on Honda cars: [xxx] no accident or injury resulted - merely trying to avoid a future safety issue information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Traveling up a hill of 5-degree incline. 20 mph speed limit. Came to complete stop, pushed reverse button. Back over prevention camera did not activate. Did not depress gas pedal. Vehicle rolled backward 35 feet before coming to rest partially in traffic and partially in private driveway. Instrument panel indicated vehicle p for park throughout the entire event. After coming to rest: (partially in traffic) vehicle would not shift out of park. Error messages on instrument panel stated: "stop driving when safe. Transmission problem. See manual. " check engine was not illuminated. Turned off car and back on. Same error message was still present. Gear selector buttons would not respond and vehicle remained in park, partially stuck in traffic. Repeatedly attempted to get vehicle to shift out of park. Eventually the battery positive terminal was removed and reapplied and tightened vehicle started, error message no longer present. Vehicle shifted out of park into reverse. Back over prevention camera activated at this time.

Audio screen reboot issue - the audio screen turns off while driving and takes several minutes to reboot.

My auto-electronic braking was randomly engaging while I was driving. It was unnecessary, & scary. It would just engage, then stop. Then, my emissions systems light came on, & would not go off. I had to get to a safe place. The dealership told me to bring it to them, it never went off the warning was on consistently. It never blinked or went off @ all. I was on the highway, & they kept it overnight. They told me they cleared it & the emissions code never came on. Yes, it did. They still have it tonight bc I refused to take it back, when I was clearly being told I did not see what I saw (even parked) where would I get that from if the light didn’t go come on? they refused to acknowledge what happened, & as of right now I’m in a rental even though they wanted their rental back. It’s a 2023, bought brand new. Full warranty, & they are putting people @ risk. I drove as slow as I could, & followed the directions from the owners manual. I could have been re-ended, due to erratic braking, & my entire vehicle could be destroyed if Honda refuses to own up to the malfunction. I have had problems w/this SUV since the 1st week I bought it. I believe it should be taken back under the lemon law! it’s not safe! not even 7,000 miles on it yet. I bought it w/7 miles. It started by saying I was departing my lane when I wasn’t for about a week, then the brakes would just slam on randomly. They said they reset it, they refused to change the oil @ 70%, had a new guy, who stated the emissions light did not come on! it did! I drove as slow as possible on the highway to get it to service bc I had no choice. They said the the camera was dirty, then the braking was fine, via the code went off, but did not drive it. They literally called me a liar that the emissions light didn’t come on. It was on when I drove it in, & left it. They did not inspect emissions. Emissions has nothing to do with their explanations. I don’t have an invoice yet, I refused taking it back. They haven’t even driven it.

I am having an issue with the turn signal / emergency flasher not making any noise while in operation. The system visual components work fine. It's the inability to hear the flashing of the signals while driving down the road this could lead to issues with other cars trying to interpret the intention of the movement of my car while I am driving. I went to the Honda dealership (gillman Honda) service department and was informed that my particular model does not have a fix or capability for the sound level to be adjusted, whereas other models (pilot, accord, etc. ) do have this capability. Replacement of the flasher is not an option. Could the NHTSA please create a minimum decibel level standard to help insure safe operation of vehicles on the roads.

Rear camera is malfunctioning. The view is blurry and frequently distorts to a green saturation removing visibility to the rear of the vehicle. This is a major safety hazard as the visibility is unpredictable and is obstructs the critical view behind the vehicle. Previously there was no issue. The issue only started occurring after a recall replacement was performed in December ‘23 for a similar issue. Previous recall info: recall 23-047 fakra cable inspection cause: fakra connectors update correction: fakra connectors update op code # 0101t0 1. 70 - the replacement from recall or camera is faulty and needs replacement. Honda is stating they will not take action without a diagnosis which they are stating will cost $200 to the consumer. Please help protect the consumer here as it appears Honda is well aware of the issue persisting beyond the previous recall and purposefully not taking action.

When engaging the accelerator after auto-stop the entire vehicle stalled. Nothing was displayed on the dash or media console, the vehicle cut off, no steering, and no acceleration. When attempting to restart the vehicle it failed multiple attempts until about 45-60 seconds later. Thankfully this occurred at a redlight, but it was a single lane and other drivers behind me were not pleased. This has happened twice now.

The vehicle suffered an electrical failure while driving (55-60mph). During this electrical failure the engine shut off, had no power steering or brakes, and had to get the vehicle off the road and stopped under these conditions. After getting the vehicle stopped, the vehicle would not restart and vehicle ultimately had to be towed to a Honda dealership for diagnosis and repair. This has happened twice, (xxx) and (xxx), since an electronic control unit (ecu) and wiring harness were replaced under a warranty/recall/known defect on (04/12) at gwinnett place Honda in duluth, georgia. The first attempt to diagnose and repair this issue at autonation Honda in columbus, GA didn't uncover any error codes and the issue could not be reproduced so no actual repairs were made. The vehicle is now sitting at Honda in albany, GA awaiting diagnosis and repair for a second time. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The rear view camera is all red and blurry. .

On Sunday April 14 while driving on the lie middle lane a person driving at a high speed went from right side across to left lane in front of me when all of a sudden the brakes activated itself and my car nearly came to a stop nearly causing a car behind me to rear end me. This happened several times before while driving approaching vehicles in front scaring my family and I. Now my cmbs lights are permanently on on the dash. This system is nerve racking and will cause a severe fatal crash. Many people on several platforms are complaining about the same or similar issues. And understand an investigation has begun. Something needs to be done to resolve this issue. I have owned my 2021 Honda Passport since November of 2023. With 19k miles.

I purchased my vehicle in August 2023 (used). Phone calls (both through using carplay and with the phone unplugged and with genuine cables) sound terrible on the part of the recipient. We replaced the fakra cables and harness late last year and just replaced the microphone (and I got charged a diagnosis fee). The issue is continuing. It's gotten so bad that I have to use my airpods to make any calls for my recipient to hear anything I'm saying (which is illegal in my state and should not be a requirement in a car that is less than 3 years old). I've dug in to forums and this is a common issue for the ex-l trim level in the 2021 model. Additionally, this can impact the backup camera and other lane keeping assist issues. I have factory reset it multiple times and it's still having similar issues.

Car will at times not start and require to be jump started. Battery has been replaced and the issue persist. The car will randomly say collision warning when no cars are on the road.

On January 5, 2024, I was traveling to destin florida, on interstate I-24, the interstate came to a complete stop. My 2020 Honda prassport shut down do to the engine idle stop being engaged. When traffic started to move the engine would not start. I sat in the fast lane of I 24 for approximtely two minutes before the vehicle would start. Multiple attemps were made to restart the vehicle. Finally it started. This is the second time this has occurred.

Upon buying my Honda Passport 11/28/2023, I have been experiencing problems with the radio/electrical connections in my vehicle. There are times I have crackling noises in front speakers and a complete failure of sound altogether. Daily stop and start in the sound system with blank moments and complete sound loses.

Vehicle was slowing down for a stoplight on a freeway frontage road and the vehicle died. Not able to attempt to start vehicle or put it in neutral. Dealer replaced battery.

The forward colision warning comes on for no reason and brakes are getting applied for no reason. Very dangerous and can cause a rear end crash.

The idle stop start stalled the SUV at intersection while waiting at light. This has happened multiple times already over the last couple of months. The latest took several repeat attempts to get it started again.

While at a stoplight with traffic behind me, my Honda quit and couldn't be moved out of road, or restarted for service. No warning on dashboard or lights to let me know what problem was. It went through every error in the system! I had to call police to block traffic and call a wrecker to come tow me to autozone for a replacement battery. It was the wrecker service that advised it was not the first time he had seen this happen. My car is only 3 years old and did not give a warning, it just stopped in traffic putting me and others in danger. I had unnecessary cost and repairs that should never had to be made. The local police had to use resources that took time away from them as well. This was on a busy Saturday afternoon on a well traveled road. This is not in the best interest of the public! now I have to take time off work to have it looked at with dealer. All this could have been avoided if this technology was not put on the vehicle. I expect better from Honda! my next vehicle will be something without all this unnecessary technology that puts people in danger!.
