Automatic Emergency Braking Problems of Honda Passport - part 2

When driving my vehicle the emergency braking system alerts and initiates the brakes at inappropriate time. While driving on a straight road with a curve ahead if there is a car coming the opposite direction around the curve the braking system will engage. I am not at the point to go into the curve yet so my steering wheel is still straight. If I have starting to turn it will not engage. This happens daily as it is a road I take to work. This has been happening since I purchased the vehicle in January 2023.

While driving my brake warning light on the dash will come on for no reason, it will flash, beep and the car will slightly shake (similar to when the car leaves the lane without using your turn signal). This happens every time I drive. It’s not occasional. I have mentioned it to the dealer a couple of times during normal service but they say the sensor is fine. It obviously isn’t. I’m afraid it will lead to an unfortunate accident by not activating when there is a real danger of a crash. I can’t fill in every date below but the most current incident is noted below.

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.

Shortly after our purchase we started having issues with the vehicle, the backup camera is not functioning, the backup sensors are not functioning, the collision mitigation is braking abruptly while we are driving even when there are no objects in the surrounding area nearly causing us two accidents, our dashboard display has no function and the display flashes off and on. My nephew suffers from epilepsy, and he is unable to commute in my vehicle because the flashing colorful display lights trigger epileptic episodes. My partner has driven the vehicle when the vehicle’s braking system is abruptly initiated, the first time his chest was slammed into the steering wheel of the vehicle and the second time his head was slammed into the sun visor. I have taken my vehicle in several times because the car breaks abruptly while driving. The last time I took it in I injured my left arm and shoulder when the vehicle abruptly stopped, and my partner was slammed into the steering wheel while driving to work on the freeway. We had another incident where my partner's head was slammed into the sun visor. When I took my vehicle in, I was told there was there were no error codes then shortly after I received a notification regarding a recall for the issue I was having. We completed the recall, and we are still having the same issue. Yesterday 02/08/24 when I was driving home from work my car abruptly stopped/braked in the rain with no cars in front or to the side of me and I banged my knee on the side of the center counsel. While driving the vehicle will either brake or stall and will not accelerate while driving regardless of whether we are on the street or the freeway. This issue has become dangerous, and I would like to resolve this as soon as possible to avoid further injury to my partner and myself. There have been multiple incidents since the purchase of our vehicle on 01/24/23, all service repair attempts have been completed through norm reeves Honda west covina.

- automatic braking system flashes warnings for no reason, with no cars around me - parking break hasn’t taken a handful of times - no collision warning when parking brake didn’t take, front end is now damaged ** I have dash cam proof I hit the parking brake before I collided with the vehicle in front of me in the school line. Husband glued the grill pieces together to keep them from overlapping.

The automatic emergency braking system has gone off multiple times on my 2019 Honda Passport since purchasing it in February 2021. Only a few of those times was necessary, the rest have either been an annoyance or have created more of a hazard when driving. This was especially true when the braking system dramatically reduced the speed of the Honda Passport while traveling on an interstate highway, passing a truck while additional vehicles were traveling at the same speed behind me. I lost full control of the car for a minute and which only exacerbated the situation. I’m very fortunate a crash did not occur in that moment. I have never had this component looked at, but have only had the car serviced at Honda dealerships and have had the camera re calibrated a few times now. There were no warning signs, a giant “brakes” flashes on the dash once the system has been triggered into action, but there’s no way I’m aware to stop it once it’s been triggered, there’s only the option to turn the entire system off ahead of it being triggered. This issue has been happening as long as I can remember, but is generally bad on high traffic multi lane roads and single lane roads where traffic is consistent from the other direction.

Transmission, radio, and automatic braking system. Transmission lags when going slow. From a stop on a hill, the car did not accelerate when the gas pedal was pushed, almost causing a crash as I merged into oncoming traffic. It felt like it did not go into gear properly or was not recognizing the gears. Dealership advised it was the design of the transmission and not something they can fix. Auto brake sensors pick up cars that are not there, braking while driving. Especially noticeable on windy roads, though it has started to happen at stop lights. Radio has static and flashes white when operating with bluetooth connection (android product). Dealership recognizes and was able to replicate the sluggish feeling at low speeds, attempted to fix stereo (didn't work), and did not replicate the slow accelerate from a hill, but stated that there are issues with the transmission design.

The monocular camera, part 36160-tgs-a13 failed. This camera drives the vast majority of safety features on the Honda Passport. Those affected features include adaptive cruise control, automatic emergency braking, forward collision warning, lane departure warning, lane keeping assistance, parking collision warning, automatic high beam control, and more. This vehicle has not been in a collision or subjected to any reason that would disable the camera. This camera, and apparently a significant number of others of this same model number appear to simply be defective. American Honda (and the dealers) indicate that the part is backordered with no eta for restock, yet oem part suppliers have the part readily available for one day delivery at $600. A quick search of the internet reveals this part failure is common, and the dealer response of backorder with no eta seems to be a standard response. The one dealer I dealt with indicated they are personally handling 2 such cases at this exact moment. Given the more than 1,000 Honda dealerships in the country, this indicates that it is more than possible that over 2,000 newer model Honda vehicles are driving on the roads throughout the country with the vast majority of their safety features disabled. Dtc code provided by the dealer is u3000-49. The problem has been reproduced and confirmed by norm reeves Honda dealer at their huntington beach California location. The resulting component failure causes nearly every warning light on the vehicle to turn on.

Unexpected braking when there are no other obstacles on the road. I need to manually turnoff the collision mitigation braking system (cmbs) every time I start the vehicle. I have notified the dealer as well as Honda and have not received any solution.

I have had 4 instances of driving on the highway that my vehicle applied the brakes automatically. My safety was put at risk because in those instances I was driving at highway speeds and the brakes were applied on their own with no obstruction in front of me. Someone could have rear ended me. I am not able to reproduce the problem on command, but it has occurred multiple times. The car has not been inspected for this issue. The only warning I received was the alert that gets triggered when the brakes apply automatically. I do recall that in 3 of the 4 times the incident has occurred, my right turn signal was applied.

The collision avoidance system is overly sensitive and brakes the car unexpectedly when there is a car slowing down in a left hand lane.

When the Passport is in cruise control I have been driving up a very steep mountain and have had the car slam on brakes with no indication to the cars behind me or me intially causing everyone to come to a halt going up a mountain with a 9% incline. I realize you can adjust the distance but it still gives no warning and it is not as if you are tailo the car in front. I turn in my subdivision daily and if I let off the gas which I have to I the neighborhood and not have to break at five or ten mph something underneath feels as if it is catching like a bike break too close it scrubs. The final thing. I have started the car remotely many times. I have done it twice in parking lots and it has jumped forward . Had someone been in from of the car standing it jumped hard enough to hit someone. Or it the car facing mine had been closer it would have hit that car as well. Thank you.

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.

I don't know which system failed or malfunctioned. It is available for inspection. While parking at the community parking lot the car accelerated. I wan't able to stop it. It jumped a bumper stop than a curb and drove up a berm and crashed into a tree. (the incident is on film at the clubhouse). I was the only one injured. My knee broke the underside of dashboard (see phpto). I did have other bruises. The vehicle is still at the collision repair shop so it hasn't been seen by the dealer. However I did report the matter to american Honda who assigned a case #13707324 on 3/17/2023. As of this writing I am told they haven't assigned same to a representative. To the best of my knowledge the vehicle has not been inspected. There were no warnings given.

My Honda Passport will trigger false forward collision alarms randomly, and for no reason. As the brake warning appears, the steering wheel vibrates. This happens for no apparent reason. It is distracting and if the brakes apply, very dangerous. My dealership says this is normal. It is not normal or safe.

The cmbs keeps flashing the brake warning light when I’m changing lanes to a center turn lane. This happens at least 2-3 times weekly. I’ve also had it brake going through a stop light when no one was in front of me and almost got me rear ended. I have not taken it to a dealer or shop to have them reproduce it because I know there’s nothing they will do to fix it so I’m not going to waste the money until I know it will be fixed by taking it in.

Cmbs issue. Failed with error message on screen. Randomly the breaking system turns on with no one around me on side roads going 50 a car could be behind me with no one in front and it forcefully stops. Had to pull over to avoid being hit from behind. Have had to pull off to the side of the road and turn my car off and then on again to stop my car from randomly breaking. Lane keeping system pulls me into old lane lines during construction. When avoiding pedestrians on the side of the road car try’s to pull me back into the lane almost hitting them. I have had to stop to correct my car.

On October 29, 2022, the cmbs emergency braking system slammed the brakes on for no obvious reason. This happened at least four or five times while traveling eastbound on I-40 in az. There were no cars in front of or changing into my lane. After it happened a few times, I called the dealer rsm Honda in rancho santa margarita, CA, where I service the car to see if I could turn it off. They suggested reducing the sensitivity, which I did. After changing the sensitivity, I still experienced two or three more incidents of surprise emergency braking for no reason. After the fifth or sixth incident, I pulled over and searched a pdf copy of my owners manual and found a way to turn off the cmbs with a button on the dash. This worked to stop the braking incidents, but I had to do it over again every time I restarted the engine after stopping for gas, etc. This scared me and was dangerous as this would happen while I was going 70 mph. I think every instance occurred while I was passing a "big rig", but I was never in the same lane as the truck. Sometimes it was on a very gentle curve, but other times we (truck and I) were both going straight down a straightaway. I had done similar trips previously in February, June, and July without having this issue, but had it happen multiple times on my October trip as described above.

Last year my wife and I purchased a 2021 Honda Passport. For the past year we have complained to Honda that the sensor for the brake assist was not working properly when the vehicle is in a curve. The sensor could not distinguish the vehicle's lane of travel and would sense oncoming traffic in the other lane as though it was in my lane, and would flash "brake" with a high pitch alarm. Up until last month, this was only an annoying issue. We complained to the dealership, who said they know about the issue, but Honda does not have a fix. We were under the impression the problem was only a passive issue. Given the lack of vehicle inventories, we decided to keep the vehicle. Two weeks ago, the sensor caused the vehicle to abruptly brake, causing an extreme change of speed from 65 mph to 45-50 mph. My wife struggled to keep the vehicle in the lane of travel. We spoke to the Honda dealership, who advise this active response is also a known issue, especially at night, and there is nothing they can do about it. We asked about a recall notice or fix. The dealership said there is nothing from Honda corporate. The dealership service department commented that the sensor has issues distinguishing the vehicle's lane of travel, especially at night, and can cause the active braking. Our frustration is with the obvious severe safety issue. My wife and son almost struck another vehicle on the freeway because of this. Had we known about this safety issue, we never would have purchased the vehicle. Honda never disclosed this safety problem to us at the time of sale, and has never made any attempt to communicate this issue to us.

The contact owns a 2020 Honda Passport. The contact stated that while driving at an undisclosed speed, the forward collision avoidance automatic emergency braking assist warning light illuminated, causing the steering wheel to vibrate. The vehicle was taken to the dealer, where the cameras were adjusted; however, the failure recurred. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 25,000.

When driving, a red brake warning light will flash across dash display and the steering wheel will start shaking. Sometimes vehicle will start braking on its on. This has happened multiple times, randomly and with no obstructions in front, or even close to the car. Scary when it occurs.

I have had two incidents of the cmbs slamming on my brakes on my 2021 Honda Passport, exl, with no threat to warrant the incident. It locked the brakes instantly and I was injured mildly the first time and the second time caused medical bills, a cervical neck epidural injection and injury to my shoulder with still does not have full movement. The first incident occurred on a busy through street and a small car about 1/2 block in front of me did a tight u turn and proceed along the medium on the other side of the street and I was also next to the concrete medium on my side of the street. My car went into full slamming on my brakes, with no warning light o and I had no control of the car. I was very fortunate that the car behind me was about two lengths back and also braked fast enough to avoid a collision. They did honk, yell, etc. , as I was pretty stunned and finally realized I should turn off my car to be able to drive again. I had a very sore neck and shoulder but thought it would clear up. I was driving apx 30 mph. I try as a rule to remember to disable this cmbs every time I get in the car but a month later I forgot the second time it happened, I was actually on the same street, same speed and there was a jacket in the road. Looked like a man’s winter jacket. As I got right up to it, I only needed to correct a little to not run over the jacket with the driver side tire. Exactly when I did that the brakes slammed on and I came to an instant stop and the brakes again locked. This time my injury was compounded and I have since seen two doctors, had an mri and cervical injection done and my shoulder is not fully functioning yet. I got the car to dealer after the first incident, but was told there was nothing they could do. Waiting until I got thru all the doctors appointments and testing after the second incident, which took about seven weeks, I went back to the dealer. They did thorough inspection, found nothing. Offered trade.

The contact owns a 2019 Honda Passport. The contact stated that on several occasions while driving at various speeds, the vehicle experienced phantom braking. The contact stated that on one occasion, the failure caused the vehicle to come to a complete and abrupt stop. The brake warning light was illuminated. Additionally, the contact also stated that the steering wheel was shaking with an unknown chime heard. The vehicle was taken to a local dealer however, the failure could not be duplicated. The failure recurred and the vehicle was taken back to the dealer, where it was diagnosed that the braking system needed to be recalibrated. The vehicle was repaired; however, the failure persisted. The vehicle was taken back to the dealer, where it remained awaiting diagnostic and repair. The manufacturer was made aware of the failure. The approximate failure mileage was 60,000.

I purchased a 2021 Honda Passport sport on April 30, 2021. Since purchasing the Passport, we have experienced a "phantom braking" problem, in which the automatic emergency braking system is deployed for a few seconds. This occurs several times a month. We have taken the Passport to a Honda dealer and they claimed that there maybe some type of obstruction on the emergency braking system camera that is causing the problem. We have not seen any obstruction on the camera and clean it regularly, but we still experience the braking issue. While no serious incident has occurred to date, we are extremely concerned that the braking issue could cause our Passport to brake and be rear ended by a car behind us.

Vehicle has slammed on the brakes multiple times now one on the highway going 60mph and in the city 35mph. Today on a open 2 lane city road, and shadow on the road with no vehicles in site slammed on the auto brakes with a collision warning while the wife was driving slowed the vehicle down. Would of been easily rear ended if a vehicle was behind in our 2022 Honda pilot, not a Passport listed for our VIN# your system is showing.

We are experiencing frequent phantom braking like the 2019 accords and crvs and believe the 2019 Passport should be included in the upcoming recall.

The collision warning flashes and brakes are sometimes activated for no reason. Almost as if it sees a phantom vehicle. Other times this happens when there is opposing traffic in the other lane but not in my path. This was reported to Honda of kirkland during a routine service. I was told no problem was found and no activations of the system were recorded in the car’s computer.

One month ago vehicle unexpectedly slowed down while driving on city street, coming to a full break. Had to pull over and restart car, which solved the problem. Did not have warning signs prior. Haven’t had problems with car since this incident. Has not been reproduced/inspected by dealers or other parties. Safety issue: risk for rear end collision.

The auto braking system comes on randomly without warning and for no reason. A warning flashing brake. Brake comes on, you can feel the brakes grab slightly. It's very unnerving in traffic and slows the car slightly. . . . It hasn't cause the car to stop yet. When I took it to the dealership they "couldn't find anything wrong with it and couldn't get it to do the same thing" I explained that it was happening randomly, that's why they couldn't get it to duplicate. This is definitely a safety hazard when driving and distracting the drive from their attention on the road. Their seems to be something wrong with the sensors but they don't seem to know what to do or are willing to acknowledge the problem. This has happened at least a dozen different times since I bought the car 4 months ago.

The automatic brake system locked up when the vehicle sensed a truck traveling on the driver's side of the vehicle. It then caused the vehicle to veer to the right and swipe a curb. This caused wheel and tire damage on both front and rear passenger side. There were two flat tires.

The vehicle’s adaptive cruise control and collision mitigation braking system are flawed. The vehicle will give false collision alerts (large brake sign on screen and shaking steering wheel) when oncoming traffic is approaching to the left of you. Both vehicles are in their respective lanes. Also, the adaptive cruise control will slow down or suddenly brake the vehicle when a vehicle to your left is driving slower. There are no vehicles directly in front of you. Both vehicles again are in their respective lanes. I have video evidence of this that I can provide. I have made Honda and dealership personnel aware of this. No one representing Honda has been able to resolve the issues. One service manager said he can’t do anything to fix it until Honda releases an update, meaning this person acknowledges there is an issue. Another service staff stated to me that his wife’s Honda pilot has the same issue and implied I shouldn’t worry about it. This is a serious flaw and I expect Honda to release an update to address this issue. This issue has been occurring since I took delivery of the vehicle (November 2019 with less than 1000 miles) and has been ongoing until present. The date and mileage listed is one of the most recent occurances.

The contact owns a 2021 Honda Passport. The contact stated that while driving at various speeds, the collision mitigation braking system inadvertently and forcefully activated and the steering wheel would shake. The brake warning light was illuminated. Norm reeves Honda superstore vista (401 w vista way, vista, CA 92083) was made aware of the failure and informed the contact that the collision mitigation braking system activated in error, sensing a possible collision. The contact was also informed that the failure occurred occasionally with curves in the roadway or when a metal sign was detected. The contact was informed that the feature operated as designed. The manufacturer was not notified of the failure. The failure mileage was 4,300.

Car will brake when no one is near sometimes jamming on brakes. I reported it to dealer 2 times. They said no software updates avalable and no codes showing a problem. I left the dealer and drove less than 2 miles down the road when the brakes can on again. I returned to the dealer again when they informed me there is nothing they can do. Maybe I have a fly on the sensor setting it off. I replied don't try to bs me, I'm a cdl driver for over 40 years.

When driving the brake warning light will flash even if I car or object is in front of the car and then just go away or at times the light flash and the brakes will lock this happens on the city street or highway.

The automatic brake goes on and off randomly. It has caused an accident in my vehicle and also two flat tires and wheel damage. The sensors will make it brake on a smooth road with no vehicles nearby. It will also brake in the rain while turning a corner. It has put my safety at risk. I have a child under 1 year old that should this brake system lock up on me and cause an accident with my child in the car it could pose serious harm. This has been an issue since I first received the vehicle.
