The first major issue I just started running into at about 90,000 miles is the engine auto start stop feature. I usually disable it when I drive due to the inability for the car to provide adequate start from a stop, but when I don’t, I’ve had the vehicle completely stall on me at a stoplight and won’t let me restart the vehicle for several minutes leaving me stranded and vulnerable sitting in a lane on a highway. I’ve had about a dozen instances of this issue now over the last several months. The second issue is with the adaptive, cruise control or the emergency, stopping on the vehicle where it will jam on the brakes, even though there are no cars in front of me it inaccurately picks up vehicles in the oncoming lane. There are more than 8 feet separated from my vehicle. I have had the system recalibrated and have complained about it at the dealer, but I’ve been told that there’s nothing wrong with it. Just thought I’d report that as well because it’s almost got me into several accidents by jamming on my brakes for no reason and almost being rear-ended.

The auto-start/stop function sometimes fails to restart the engine after coming to a complete stop. Vehicle is left stranded in a traveling lane.

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.

The engine suffered a failure of the connecting rod bearings and wrist pin or pins. It necessitated a short block replacement.

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. ***.

Auto idle stop feature fails and I can not get the engine to start for a few minutes. I get stuck in traffic with horns honking behind me and people mad and passing me in an unsafe manner. I have replaced the battery and have had the battery and starter retested; they are ok. I brought it to easy Honda, in houston, and they say they can't find anything wrong, since it only happens intermittently. My problem has existed since I bought the vehicle new. I have 55,000 miles on the vehicle. Also, intermittently, the engine will not crank over when it is a hot engine. I live in houston, so it is hot a lot. I read that this is a problem with millions of Honda and Acura vehicles. When can we get some help on a fix?

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.

[xxx] start/stop system failed when stopped in starbucks drive thru. Unable to restart, or move vehicle. Honda Passport had to be towed. Problem has not been reproduced or confirmed by a dealer. Honda dealership deep charged battery and battery tested good? I was charged a diagnostic fee for starting & charging systems & battery. Test name was gr8 diagnostic test by Honda. Vehicle was inspected by local Honda dealer. Diagnosed parasitic drain on battery? a new battery had been purchased 9/16/2024 @ a Honda dealership in va. New battery is just 6 months old. Never had a problem with the new battery or start/stop system until [xxx] when failure occurred. There was never a warning lamp, message, or other symptoms prior to the failure. Original start/stop recall repair done 5/2/2023 at Honda dealership. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

While at a stop light, there was an engine start failure that caused the vehicle not to restart. It took me approximately 5 minutes to get it to start again.

While stopped at a busy intersection under a red light our 2020 Honda Passport's 'auto idle stop function' had automatically stopped the engine with the brakes applied, upon releasing the brakes the engine did not restart as it was supposed to. I reapplied the brakes which were no longer 'powered brakes' and tried ot restart the vehicle but it would not start. A message came up on the dash to put the vehicle in park which I did. At that point when starting the vehicle it did start, put it in 'd' and drove past the interection to the relief of all those behind me. Had this been my wife I doubt she would have been able to do this as quickly as I did. This is a safety hazard and Honda needs to have a recall to fix this issue. Currently we are trying to remember to keep the 'auto idle stop function' in the 'off' position. We bought this vehicle new and have kept it in great condition.

Car feels sluggish and delays accelerating when driven. Occasionally will make a strange sounds when trying to accelerate. The automatic brake will engage when there no obstacle in front of me while I’m driving- has happened a few times since I bought the car. At times, the car will not turn on when the ignition button is selected for no apparent reason.

I purchased a 2021 Passport this week with 22k miles. Test drive was great, but the next day I noticed a knocking sound coming from the engine at low rpm on a warm engine. I took back to the dealer twice and they told me it was normal… I took it to another Honda and they diagnosed crank bearing knock. I just purchased this car with low miles and it has engine problems which is very scary. Maintenance records are great. I’ve been reading forums and this problem is very common with these engines. A lot of people have been told it was normal, but it is not. It’s very scary and dangerous to find out I bought a defective engine. I have a video of the knocking sound.

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.

I was exiting a highway onto another highway. It was a pretty sharp exit to the right. The vehicle lost engine power, and I couldn't travel greater than about 40 miles/hour. The vehicle would not respond to my pressing the accelerator. Upon getting off the exit onto the next highway, I immediately pulled over and shut the vehicle off. I waited a few minutes before restarting the vehicle. Once I restarted the vehicle, it was back to normal. There were no further issues for the rest of the drive (about 90 miles). This has happened 3-4 times since I purchased the vehicle.

The idle-stop system engages as expected when the vehicle comes to a stop, but the engine fails to restart when I release the brake pedal. This leaves me stranded in traffic and vulnerable to collisions, especially in high-traffic areas like intersections. The car has completely stalled and remains frozen for at least 3 minutes. Instrument panel lights up and says to depress pedal fully and press the start button. Another message says something about being in neutral and then to put it in park. I'm doing what it says and I cannot get the car to start. I have a green light and I'm stuck in an intersection where opposing traffic has a green light as well. People are honking at me and nervous because of the unpredictibilty of my car. - frequency: this occurs at least 1x/month for the past 65 months (lifetime of the vehicle) - conditions: occurs during normal driving conditions, typically in stop-and-go traffic. - impact: this issue has resulted in significant delays and near-misses with other vehicles, posing a clear safety hazard. The vehicle has been evaluated by a Honda dealer regarding idle-stop system malfunction specifically on the following dates October 1st, 2020, February 2nd 2023, March 16th, 2023 may 11th 2023, November 7th 2024 and January 9th 2025. The vehicle was found to be in normal working order and multiple times I was told to disengage the auto idle stop (press the button) to prevent that from happening. There was a recall for idle-stop software update which failed to repair the issue. This has been a persistent problem and the above dates by no means reflects the only times that the engine fails to restart after auto-stopping.

This issue has happened three times. The first two times, I attempted to accelerate while driving on the highway and the engine momentarily lost power. I would say the events lasted 3 - 5 seconds. The third time, the engine lost power while I was driving on the highway and the vehicle never regained enough power to go over 26 miles an hour - with the accelerator depressed to its maximum limit. Fortunately, I was near my exit, so I exited the highway and drove the car 4 miles to my destination. This is the only time out of the 3 instances a flashing "check engine" light came on. I shut the car off, went to my appointment and then restarted the vehicle approximately 30 minutes later. No other issues were noted on the 3 hour return trip. This last event happened on [xxx]. I took the car into the service department at ken vance Honda, in eau claire, WI on January 29, 2025 and they were unable to find any stored codes in the computer related to the issue. The service advisor said he has heard of this issue several times. The estimate to fix the issue was roughly $850. 00 with parts accounting for $501. 74 I researched this issue online and found several references to it. The first is a post from a online group for Honda odyssey owners. One post in that thread leads to another thread for Honda ridgeline owners. The first website: [xxx] and the post on that site that has a link to the second and more damning site. Mtman 124 posts · joined 2017 #4 · Jun 22, 2024 been a nagging problem on the ridgeline since 2019 on cold winter days. [xxx] there are several other references to similar issues on the internet and Honda is obviously aware there is an issue. Information redacted pursuant to the freedom of information act (foia), 5 u.

At speeds above 55 mph, car will make a noise like paper being torn, followed by a loss of throttle response. This lasts for 3 to 5 seconds, then everything returns to normal. This has happened with the cruise control set, or while under foot control. No warning of any kind show up on the dashboard. We have taken our vehicle to the dealership on may 15 2025. They could find nothing after polling the computer or on multiple road trips. This loss of throttle has occurred six times in the last five months. We will keep a written record of these events as they happen, and pray that nobody gets hurt or dies from this.

The 3. 5 engine is ticking (knocking hard from 1-2 rpm same engine that is in all the recall on pilots and other Honda cars! my car has 65k miles on it . Honda has it for a week they can’t figure it out and say it’s normal. I know my car and a loud tick is not normal! Honda knows these engine have issue and don’t want to fix it. I’m now out of warranty and they don’t want to do anything basically they want me to get stranded when it breaks down or I’m in an accident if my engine breaks.

Engine restart failure. Vehicle approached intersection, came to complete start and engine stopped. Vehicle would not restart when I lifted foot off of brake pedal. I had to shut vehicle off, waited a few minutes and restarted it again. Vehicle's auto idle stop system was activate at time. On 12/11/2024 reported incident to nucar Honda, norwood, MA. They were unable to duplicate issue.

Auto stop feature will engage when I stop the car at a light, and then the engine will fail to turn back on when I take my foot off the break. I then have to try and get the car to turn off so I can restart it. I’ve taken it to Honda and they did a system update and also had the battery replaced. It was better for a while, but has now happed again twice in the last couple months.

The contact owns a 2020 Honda Passport. The contact stated while attempting to stop at a red light, the vehicle lost motive power and stalled. The vehicle was restarted after the third attempt however, the failure persisted. The vehicle was taken to a dealer to be diagnosed. The contact was informed that the starter needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 31,000.

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.

The brake and tmps ights came on for no reason while driving. I pulled over to the side of the road in fear of my safety. I restarted the car to see if they would clear but unfortunately they did not. The manifold and gasket were leaking. The vehicle has been misfiring.

The contact owns a 2019 Honda Passport. The contact stated that while stopping at a red light, the vehicle inadvertently lost all motive power, after which the vehicle was able to restart. After restarting the vehicle, the vehicle returned to normal functionality, but the failure became a regular occurrence. No warning lights were illuminated. The vehicle was taken to the dealer, who was unable to diagnose a failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The VIN was not available. The failure mileage was 60,000.

The vehicle does not restart after entering 'auto idle stop' even with latest software update by Honda. About 2 month ago, my car started to act weird and stopped restarting during traffic stops, causing dangerous situations. (I was waiting in the intersection to make left turn and the vehicle was stopped in the middle) I went to Honda dealership for repair, and they explained that its known issue and can be solved by software update. They promised that it won't happen again, but starting few days ago, it is doing it again. I went to the dealership again, and they are now saying that they have to replace the starter. I don't think it is a safe approach to let customer "test" the software and replace problematic part depending on the test outcome. I feel like Honda should update the software and replace starter.

Was driving at highway speed on the garden state parkway when the vehicle went into limp mode and many errors codes appeared. Was barely able to get on the shoulder then limp to a parking lot at an exit. Car had to be towed to the dealer where it is in the process of having a rocker arm spooler valve replaced that controls the vcm in the bank one cylinders. This created an extremely unsafe condition that nearly caused me to have a high speed accident.

The engine lost power and shut down while driving on the highway. The vehicle has been at a Honda dealership since this date (so about 8 weeks now). It can be inspected but I am on the verge of replacing the engine at my cost. The loss of power resulted in putting the vehicle on the side of and icy highway at night and at risk of being hit or sideswiped. There was very little cell service which meant that a tow truck couldn't be called right away. There were no warning signs that the engine was experiencing trouble before this engine failure. The problem has not been reproduced by the dealership. They have inspected the vehicle and have only pointed to low oil/leaking oil as the issue. I myself have no evidence of leaking oil or low oil. There again, were no warnings/symptoms prior to the failure. The problem occurred at the moment that the engine supposedly failed completely. The dealership and american Honda have not entertained any failure other than the low oil and my oil change which occured 5300 miles and over three months prior. I cannot understand as a consumer with a powertrain warranty and a car with some known recalls (fuel pump/ connecting rod) refuse to be concerned for the safety of their customers and use my vehicle to determine what the real issue was or is.

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!.

This happens intermittently since I have owned vehicle. When car is stopped for a light or stop sign the engine idle stop engages. Then the car will not start up again when foot is taken off brake. In fact car automatically switches into neutral and care will not start. I been stranded on busy roads and almost hit twice because of this issue. I also had to purchase a new battery as I was told this is what was the issue by dealership and my battery was out of warranty.

My car is equipped to cut off when you come to a stop. It has failed to restart after taking your foot off the brake a couple of times, and it has been slow to restart many times.

The auto engine idle is failing to properly restart the vehicle. After coming to a complete stop the vehicle will not restart on its own. I have to put the vehicle in park, wait a few minutes and then push the start button to restart the vehicle. The vehicle will be available for inspection upon request. My safety and the safety of others has been put at risk numerous times. The vehicle has failed to restart mid-intersection in heavy traffic. , on the highway during stop and go traffic, and at stop lights. The problem has not been reproduced or confirmed by a dealer or service center. The vehicle has not been inspected by the manufacturer, police or insurance company. No prior warning signs, messages or lamps have appeared before the problem.

This has happened 3 different times starting on 5/28/23. While at a stop light the engine shut off function goes into effect. The engine then shuts off and won't restart until you put it back in park and restart the vehicle. This is dangerous and could cause accidents when in stop and go traffic.

Since I purchased this car in 2020, I have regularly experienced my car stalling out because of the auto idle function. The car shuts off when I brake and then does not turn back on, leaving me stranded in traffic until I can manually shut off my car and turn it back on. This is a major safety hazard that Honda has yet to properly address. Honda had a recall to "fix" this, which was just a software update. This was conducted 5/12/2023 on my car. Unfortunately, today (5/20/2023) my car stalled out again at a traffic light due to the auto idle function. Honda needs to address this issue, and if they cannot, then they need to provide those with defective models a path to upgrade their car.
