Warnings problems of the 2021 Honda Passport

Cmbs (collision mitigation braking system) problem.

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. ***.

Driving on 684 in new york state and the car started to break and no objects or cars in front of us. Dash-broad light came on and it said break. Traveling doing 70 mph and car went to 50 or so in seconds. This goes on about once a week in different areas.

The emergency collision system constantly actives when there is no need for it to activate. It’s more of a safety hazard. I have just under 40 years of driving experience, former mechanic, and police officer for over 20 years. My professional opinion is, Honda needs to correct this problem. Thanks.

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’ve had several incidents where my vehicle has forced me to a screeching hault when not needed. Most recently it did, and I was almost rear ended by a large uhaul truck while my baby was in the backseat. This is extremely dangerous. This anti-collision system activates while on turns and when nothing else is happening around the vehicle. This is a safety feature that makes the vehicle more unsafe.

The sensors simply don’t work. Cmbs system constantly raises warnings, often alarming me as a driver, almost creating accidents. On one occasion, coming into a turning lane of intersection with green arrow and cars moving forward into left turn, cmbs actually applied the brakes for about 1 second, alarming me and causing the driver behind me to react as well. There’s no permanent disabling of this feature, which is a mistake by mfg, and we often forget to turn off starting each drive. Blind spot is often throwing false alarms. Lane detection too, but we permanently turn off lane detection.

The forward collition mitigation system is constantly braking on its own for no apparent reason. It happens a lot when going around a slight right turn and it interprets cars coming the opposite direction in the other lane as a trigger to start braking. It is a very dangerous situation each time, so I turn off that feature every time I start driving now to avoid it.

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.

We drove about 100 miles yesterday. It all happened. False brake light flash and brake applied because of oncoming traffic. Heavy brake application because of car in the left lane making a turn. Can't tell you how many times I've almost been rear ended, and people blasting their horns at me because this foolish car slams on the brakes for no reason. People think I'm brake checking them. Had 2 Hyundai before this, never encountered this. Honda needs to be forced to fix these issues. There are hundreds of similar complaints in online forum about this problem. This has happened many times, especially on an extended trip, like yesterday, over 100 miles round trip. Dealers do not have a fix for this. Honda needs to be forced to address this and fix all problem vehicles.

On my way to work I was on the highway and five warning lights came on out of no where. All five warnings were the safety assist systems had problems. I drove to the Honda dealership and found out it was my microchip for my Honda,the main microchip for all of the safety and system controls were dead/bad and that it would need to be replace. I was told by the service manager that without the micro chip the vehicle would no longer be drivable as it controls power steering system, brakes system, lane departures, etc. If I would have ignored those warning lights, all of those systems all systems would have failed putting my life at risk and others in their vehicles as well . My vehicle was bought with 3 miles on the speedometer and was only 2 years old at the time of this occurrence.

Driving 65mph on 3 lane highway in l=far left lane in light snow with anti-collision on. Then instantly car auto braked, car slowed dramatically very fast and despite me stepping on gas pedal, car continued at a crawl on major highway. Fortunately no car was close behind or it would have hot me with such rapid decent. I moved to the right shoulder across 3 lanes and car continued to be unresponsive to gas pedal. Honda stated that front camera must have been covered and thus system operated correctly. They did say gas should have responded when I turned the wheel, but it did not. Honda said it won't respond to gas pedal, but this is very dangerous and takes control from driver. The system should be a help but never take control when driver directs otherwise. Had there been more and closer traffic, an accident would have been likely.

Our 2021 Honda Passport ex-l sometimes hits the brakes on its own. It happens every now and then, like when I'm exiting a freeway, or sometimes even when going with the flow of traffic. I've seen this issue talked about in the Passportforum. Com, but today I saw an official article citing NHTSA concerns, so I'm writing to say that I too have experienced this potential dangerous issue while on road. My vehicle randomly brake checks on its own when it falsely detects the situation in front of me, which could result in a rear end collision. I'd like to see this issue resolved, so please feel free to contact me if you need any more information. Even back in 2022, I was experiencing this issue. This has happened occasionally. The last time was about a few weeks ago on the freeway. Please see the forum screenshot for my reference-- I'm "tombox" in that thread. . Read more...

Vehicle has led headlights. In snowy conditions at night, buildup on headlights caused extremely reduced visibility. Required frequent pulling over, getting out of vehicle, and clearing headlights. Not a safe situation in the snow. Never had problems with halogen or hid lighting so I suspect it’s a heat issue due to led lights operating much cooler. Also, snow buildup on grille emblem that houses radar for accident avoidance causes system failure which results in instrument display of failure. The warning box completely covers the speedometer so you have no idea of your speed. Also not good in snowy conditions. This can be turned off, but not while moving, and defeats the purpose of the avoidance system.

Forward collision warning (fcw): at random intervals, the fcw will give a false positive warning of an imminent collision with a car approaching from the opposite direction. This has occurred at various times over the past 2+ years. Comments to this effect to the Honda service representatives have indicated that this anomaly has been reported previously. They have not provided a fix or software update to correct this issue. The event is a safety issue because of the distraction from focusing on the road ahead. Although the automatic braking system has not been employed, the driver may in response to the false warning apply the brakes and cause an accident inadvertently.
