Automatic Emergency Braking Problems of Honda Pilot - part 1

Collision mitigation braking system has activated numerous times while traveling on a straight road with no other vehicles around. The brakes activated hard where items shifted in the vehicle and the seatbelts locked. Occupants were thrust forward at the time of braking. Contact was make with the dealership and there are is not any fixes advised.

Bought car late March 2026 from Toyota dealership . Collision mitigation braking system randomly engages. Forcefully slamming on brakes ( approx 1-2 seconds and then releasing) when nothing is in the road or around. No rhyme or reason , no consistency as to when it happens. Since purchasing it has happed 9-10 times. **7/15/26 - visit Toyota for routine service, expresses my concerns. They said they couldn’t see anything bc their systems can’t diagnose Honda. **7/21/26 - Honda dealership . Says sensors are fine. (spent less than 10 mins driving the vehicle). And recommends to turn the anti-collision feature off . . But it has to be turned off every time the vehicle restarts. ??for safety reasons - I don’t feel I should have to do this … the problem should be looked into and taken seriously. I can only imagine the catastrophe if I were in bumper to bumper traffic and it happens, causing a pile up.

While driving down the road the emergency braking turned on many times when I wasn’t even near a vehicle. It turned on about a total of 10 times without a car being unsafely in front of me. I just got this vehicle today and I’m worried about whether I should keep it or not because of this.

* collision mitigation braking system (cmbs) – southeastern Honda: shortly after purchase, the cmbs repeatedly slammed on emergency brakes without cause, incorrectly flagging adjacent or oncoming vehicles as collision threats. I presented video and photo evidence to southeastern Honda. The service manager dismissed the hazard, telling me I "just have to learn how to drive the car with these driver assist features. " fearing an accident, I was forced to permanently disable the system. * starter failure / battery issues – space coast Honda: the vehicle went through four batteries and repeatedly failed to restart when auto idle stop engaged, stranding my wife and children in parking lots and active traffic. I brought the car in multiple times insisting the starter was the issue, but space coast Honda refused to replace it because no codes were present and my VIN wasn't attached to a recall. Once out of warranty, I replaced the starter out-of-pocket, which permanently resolved the issue. Teardown of the original starter revealed extensive heat damage, burned insulation, and charred components. * current engine concern – space coast Honda: the engine now exhibits rod bearing failure symptoms aligned with recall 23v-751, including knocking and metallic debris in the oil and filter. I brought the vehicle and photo evidence to space coast Honda. One staff member claimed metal in the oil was "normal," while another disagreed. I left the car for evaluation, but two days later learned no inspection was done; they claimed Honda would deny it based on VIN exclusion and quoted $13,500 for a used engine. When I insisted they present my case to Honda anyway, they abruptly raised the inspection fee to $800—despite having completed zero diagnostics over two days.

What system failed: the automatic emergency braking system (ebs) engaged without warning, causing my car to stop abruptly on a public road. How was safety of myself/others at risk: I was turning right at a 4-way stop intersection after coming to a complete stop. There were other vehicles parked/driving on the street but none of them were close enough and no one was going fast enough to be a danger/trigger the ebs. The ebs on my car engaged without warning, stopping my car completely and blocking the intersection. Luckily the vehicles behind me and approaching the intersection were going slow enough to avoid a collision. Has the problem been confirmed: the Honda dealer where I bought the car brand new refuses to inspect the system, claiming it's normal for emergency braking to occur due to reasons other than to avoid a collision (snow in the air/a bird flying past/etc. ). Vehicle inspected: no. Warnings/symptoms: none.

My 2019 Honda Pilot ex-l (perfectly maintained and with only 72k miles) just started displaying a "braking system" failure warning light along with dash notifications that a number of critical safety systems are no longer functioning, including: forward collision warning, automatic emergency breaking, lane keeping assistance and departure warning, adaptive cruise control, and more. The car registers a failure code of "u3000-49" which I've learned is related to a bad front camera - a problem apparently plaguing so many Honda vehicles like mine that there is now a class action lawsuit (jones, et al. V. American Honda motor CO. , inc. ) related to it. Given the lawsuit shows how pervasive this situation is, and the nature of the safety risks involved, I hope this issue will be elevated to a formal NHTSA safety recall along with reimbursement for repair expenses (mine will be about $1500).

When driving on the highway vehicle suddwnly brakes on its own when it detects cars on side lane not directly in front of me creating a noticeable slowdown being somewhat unsafe. The wiper blades dont come up they hit the hood of the car which I believe shouldnt be this way. The seatbelt sensors go off in back row even if no one unbuckles then the car starts making loud noise to let you know and a side unbuckled light comes on and also the x marking which seat but it continues making loud beeping noise that can cause distraction and even an accident I drove 45 minutes with it doing this to me on and off mostly on the only way to get it to stop is if someone doesnt sit on marked spot. So now I dont know if this will happen on all seats as for now its obly on the third row passenger right side seat. I have about 3 weeksnoticing this but it was less now its more so I made apptment to take im to get checked but the sound is very anboying and distracting.

The collision mitigation breaking system has wrongly engaged the breaking system on two occasions since I have purchased the car in September 2025. The car is available for inspection. Both times, the car hard braked when turning right at stop sign. The second occurrence, today, 5/15/26 the car also honked. I plan to call the dealer tomorrow report the issue but from what I have read so far this is a known issue with no resolution and is not easy to replicate, therefore I am filing this complaint to document the issue. Both times this was very alarming for me. Today, there was another person at the stop sigh to my right and a pedestrian a bit a way when the car slammed to a halt and honked, alarming me and probably them as well. There was no warning or alert, the car just halted.

"on Friday afternoon, while driving alone on an open stretch of road at approximately 40 mph, my 2025 Honda Pilot's collision mitigation braking system (cmbs) experienced a catastrophic malfunction and initiated full emergency braking. The brakes locked up aggressively with absolutely no vehicles, pedestrians, or obstacles present in front of me. A transient warning light flashed on the screen for a few seconds but disappeared too quickly to read. The violent deceleration slammed me forward against the driver's seatbelt, causing physical trauma. The brakes released after a few seconds, allowing me to regain control and park the vehicle. I sought medical care first thing Monday morning, resulting in a diagnosis of acute neck strain and petechiae, as well as necessitating a specialized cardiovascular evaluation to check my pacemaker function due to localized swelling under the seatbelt line. The vehicle is entirely unsafe to operate, has been parked in my garage since Friday and is currently awaiting a Honda care tow truck for dealer transport and data retrieval. ".

The contact owns a 2025 Honda Pilot. The contact stated that while reversing, the automatic emergency brake unexpectedly engaged. The check engine, abs, and several other unknown warning lights were illuminated. The transmission failed to shift into the intended gear. The contact turned off and restarted the vehicle and was able to shift into the intended gear. Additionally, the transmission jerked while accelerating, the rpm failed to increase while accelerating. The contact stated that the doors failed to open immediately after pressing the fob key, and the infotainment screen was flashing. The contact stated that the failures were intermittent. The vehicle was taken to the dealer, who was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 35,000.

There are three dangerous systems in my 2025 Honda Pilot ex-l that should be permanently disabled or removed by the manufacturer or dealer. In order of danger; (1) collision mitigation braking system, (2) auto idle stop, and (3) road departure mitigation system. All three of these systems have nearly caused wrecks for me several times. The collision mitigation braking system (1) is especially dangerous for rear-end collisions to the vehicle using cmbs. Example, I was driving in heavy traffic in the middle lane on I-40 near hermitage, tennessee on 23 Apr 2026 with adequate distance between me and the car in front of me. A tractor-trailer was close behind me. Suddenly, a car in the lane to my right moved into the gap in my lane between me and the car that was at a safe distance in front of me. The cmbs activated and started braking the car. I pressed the gas pedal hard to try and maintain my 70 mph speed to no avail. The tractor-trailer swerved into the lane to my left missing the rear of my car by inches, and avoiding a massive chain reaction collision of many cars. This was a near fatal event for me. Without cmbs, I would have simply held my speed steady until I could create a safe distance and ease into a safer position, possibly in the lane to my right, a much less eventful situation. The auto idle stop (2) has a knack for shutting off the engine when I am trying to make a left turn in heavy traffic. After several near misses, I have learned to turn this system off when starting the engine (the default is on). The road departure mitigation system (3) shakes the steering wheel if the system thinks you are moving out of your lane. It shakes the steering wheel to alert you. Twice, I was caught by surprise and overcorrected the steering when the road departure mitigation system started shaking the steering wheel. So instead of staying in my lane, this almost caused me to go out of my lane and possibly collide with another car or a road barrier.

My 2022 Honda Pilot failed to engage drive after reversing, despite the drive button being pressed. This resulted in an unintended backward motion & a collision with another vehicle. 1. What component or system failed or malfunctioned…? the electronic transmission shift-by-wire system (push-button shifter) failed to respond to a gear change request. Additionally, related electrical systems including the dashboard infotainment system & the integrated usb charging ports have malfunctioned. The vehicle & its components are available for inspection upon request. 2. How was your safety or the safety of others put at risk? the vehicle experienced unintended motion. While attempting to move forward in a parking lot, the vehicle remained in reverse despite selecting drive. This failure led to a low-speed collision with a truck’s tow hitch. This defect creates a high risk of crashes, injuries to pedestrians, or property damage because the vehicle does not move in the direction the driver has selected. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? the vehicle was previously serviced at a Honda dealership for a radio/infotainment recall. Since that service, the transmission has failed to engage drive multiple times at random. 4. Has the vehicle or component been inspected by the manufacturer…? the vehicle was inspected during the initial recall fix. And brought back because after the fix because the charging port stopped working/continued screen glitches. Following the recent collision, it is awaiting further inspection by a Honda dealership to determine the extent of the mechanical failure. 5. Were there any warning lamps, messages prior…? symptoms began after the recall fix & included intermittent electronic failures of the charging ports/screen. There were no specific transmission warning lights prior to the gear selection failure; however, the persistent electrical issues in the dash area suggested a systemic electronic malfunction.

My current 2020 Pilot has presented a failure/ malfunction at the multipurpose camera in the front side resulting on the most important safety advance drivers assistance systems to not to work (collision mitigation system, road departure mitigation system, auto high beam, lane keeping assist, automative emergency breaking). This malfunction for this safety device could put at risk my family while driving since system got deactivated for no reason and will not respond to under unexpected situation while driving. I notice several messages on my dashboard then I confirmed safety componentes where bypassed and not activated not working properly. The problem was reporte at a dealer, then vehicle device was inspected and confirmed by the dealer that the safety multipurpose camera has a malfunction. Prior to the failure there were no messages or symptoms, just stops working without advice. Safety devices must he operative at all time, me vehicle is in very good condition and not more that 6 years old.

Multiple malfunction warning lights came on stating the adaptive cruise control, emergency braking, lane keep assist, automatic headlights, etc. Were not functioning. The Honda dealer attributed it to the forward facing multi-purpose camera. I was told they have seen the same issue before. It's a very expensive part to have replaced ($1846. 50). While researching the problem it appears to be a very common problem with Honda and I'm sure the dealership is not forwarding this information to you. This is a safety issue and I'm sure people are driving around without fixing it because of the cost. The cost to fix this problem should be absorbed by Honda since it is definitely an engineering issue. Fortunately, I had an extended warranty on my car that covered most of the cost.

On April 2nd, 2026. I was driving this car into a parking space. I had to be going 5 mph. Or slower. Probably even slower. Pulling in. . I applied the brakes of course. The car wouldn’t stop. My husband/passenger told me to stop. I did stop. This car kept rolling and crashed/smashed/ hit the brick red building in front of us. No brake hold was displayed. . No nothing. No brake stop. Nooooo nothing. The car wouldn’t stop. I never in my life have ever experienced this.

I just drove into a parking lot at first united methodist church parking lot. [xxx] . This is where I work. Approaching a parking space very near. Driving into the space, applying brakes like I’ve done for the last 12/13 years…. The car would not stop. I applied the brakes fully down to the floor( which I’ve never had to ever do at any time) the car kept going. . Rolling on. My husband the passenger told me” stop”. I did stop. I was applying the brakes as soon as approaching the parking space. The car kept on going as I said. No warning like” brake hold” which has worked another other time when getting according to this cars brain. . It would show some kind of warning. It did not. No sound, no nothing to brake the car. It rolled right into the red brick building I was pulling into. Their parking space. The building has about a two foot gash on it. The car did this …what kind of car doesn’t stop. With all of the sophisticated sensors or etc. It has…why, what happened? my granddaughter was in the back right passenger seat. The impact caused a gash above her forehead. A real cut, mind you. I don’t know what else to see. I’ve never experienced this. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Driving around 60 mph and car flashed brake on dash like it was to close to other vehicle and locked up brakes. Immediately went back to normal.

I will be driving down the road with no other cars in sight and the car will sense something that isn’t there and engage in emergency braking. This is very dangerous when traveling at high speeds.

Drive to work suddenly engine show emergency issues many symbols appearing in front of screen and break is not controlled and car is stop running.

I was driving around 30-35 mph when my car's dashboard lights were flickering on and it then gave me a warning that the collision mitigation system was coming on. The car started braking hard and it swerved me to the left, so much so that I was halfway into the left lane. Thankfully no other car was in that lane. Then my car automatically went into neutral and I had to stop on the side of the road. I took the car into the Honda dealership the same day. They told me that it could possibly be a dirty multi use camera by the rear view mirror and so they claimed to have cleaned it. I'm not certain that was the issue since I had just gotten a car wash recently and it did not seem to have been dirty.

The front camera is kicking a code of u3000-49 so now none of my safety features work nor is Honda 100% certain on how to fix his issue. I've spoken to Honda and no one can provide a clear answer. I'm not driving my car with my 2 small children because it's the only car I have and none of my safety features are working due to the damage from the front camera. I've been told by a glass service, it's likely due to heat damage as Honda's front camera are known for this. This could cause so many issue, especially since Honda isn't giving any feedback on how to correct this issue.

“the vehicle experiences phantom braking while driving, where the collision mitigation braking system (cmbs) activates without warning even when there are no vehicles or objects in front of me. The vehicle suddenly brakes on its own, creating a major safety hazard and risk of rear-end collisions. The issue has happened multiple times during normal driving at different speeds. Warning lights related to the collision mitigation system and passenger airbag system have appeared intermittently. The blind spot monitoring system has also failed to properly detect nearby vehicles at times. The vehicle was previously taken to the dealership/service department and remained there for an extended period for inspection and attempted repairs, but the problem was not fully corrected. After getting the vehicle back, the same symptoms and braking issues continued. This issue puts myself, my passengers, and other drivers at risk because the vehicle may suddenly brake unexpectedly in traffic.

While operating the vehicle in reverse at a low speed (under 5 mph), the advanced driver assistance system (adas) failed to provide any audible or visual alerts regarding a stationary vehicle positioned directly behind my path. The vehicle is equipped with a rearview video system and rear proximity/parking sensors, both of which were active. ?despite a clear line of sight and the secondary vehicle being a standard passenger car, the sensors did not "ping" or trigger an emergency brake/alert, resulting in a rear-end collision. The sensors and camera lens were clean and free of debris at the time of the incident. This represents a failure of the safety system to perform its primary function of obstacle detection in a standard backing scenario, posing a significant risk for back-over incidents involving pedestrians or other vehicles.

Without any warning or incident, the multipurpose camera has failed and several systems are no longer available. Dtc u3000-49 this includes, cruise control not working as well as auto high beams and autobraking.

The multipurpose front camera (Honda sensing camera unit) failed internally, triggering diagnostic trouble code u3000-49. Multiple warning lights activated simultaneously on the dashboard, disabling all Honda sensing safety systems including adaptive cruise control (acc), lane keeping assist system (lkas), collision mitigation braking system (cmbs), road departure mitigation, and automatic high beams. The failure occurred spontaneously with no prior accident, impact, or windshield replacement. The vehicle has low mileage and the failure appears consistent with a known design defect affecting Honda sensing camera units in 2016–2020 Honda models. The failure was confirmed by a Honda dealership using Honda diagnostic system (hds), which identified internal electronic failure of the camera unit. Safety is at risk because the collision mitigation braking and lane keeping systems — relied upon for highway driving — are completely non-functional. This issue is widely reported across Honda Pilot, odyssey, cr-v, hr-v, and ridgeline forums, suggesting a systemic manufacturing defect. Honda has not issued a recall despite the safety-critical nature of these systems. The cost of replacing the multipurpose camera is very high and prohibited for many families.

It is available for inspection. We were driving and all of sudden the car became sluggish, started slowing down on the highway and several lights started popping up. The warning lights came up after slowing down and becoming sluggish.

My Honda Pilot automatically applied the brakes 2 times while traveling on the interstate at 60 mph when there was no one in front of me and no one even near me. Both times it applied the brakes automatically and suddenly for no reason. It could have caused a bad accident. I was fortunate no one was behind me. Honda denies anything is wrong because it didn’t do it for them when they took it for a drive.

The Honda Pilot completely lost power on my husband's way home from work in a snow storm. It would not start but it did yesterday. It sounds like clinking/clunking when started but stalls out if you try to put it in drive or reverse. It has a brand new battery. But otherwise it had to be towed and is now sitting. It didnt give any warning signs or lights on the dash until after it completely broke down. It has the engine light on when started. It has not be confirmed by a dealership as times are really rough right now with a new baby and not having the extra funds to have it looked at. And not to mention the closet dealership to look at it is almost an hour away. It seems that the rods/engine area are at fault.

All the adas systems have stopped working. I get warnings and beeping as I drive my vehicle. Numerous people are telling me that it is the $2,000 front sensing camera that needs to be replaced. This is a huge safety concern and it is plaguing the 3rd generation Honda Pilots.

The contact owns a 2024 Honda Pilot. The contact stated that while driving approximately 75 mph, the brakes inadvertently activated after passing a truck on the highway. The contact stated that the vehicle unexpectedly slowed down to 40 mph. The contact stated that there was no warning light illuminated. The contact stated that while the accelerator pedal was depressed, there was an abnormal banging sound coming from under the floorboard. The contact pulled over and checked the vehicle, and saw a puddle of transmission fluid on the ground. The vehicle was towed to a dealer where it was diagnosed, and determined that the transmission needed to be replaced. The vehicle was not yet repaired. The contact stated that the inadvertent braking had occurred once before, but it was not as severe, and the vehicle was not diagnosed. During the first failure, there was no warning light illuminated. The manufacturer was not informed of the failure. The failure mileage was approximately 20,000.

Vehicle is setting multiple faults for adas system. Lkas, acc, collision mitigation system, auto high beam lights inoperable. Forward facing camera in the top of the windshield has failed.

After only 76k miles the adas stopped working. Honda sense safety features no longer work. Honda dealership diagnosed the problem and said the adas camera needed to be replaced. The car is in excellent condition. It was never in an accident, windshield in perfect condition. Up to date with its scheduled maintenance.

My car "lurches" when increasing speed sometimes acting like it does not want to go at all. I am constantly on edge that I am going to get rear ended or hit. Especially when my children are with me. Occasionally the brake light will light up and my car will slow down and then accelerate again. Which also makes me worry about getting hit. Both of these things have happened multiple times and we've done our research. It's a major issue.

When I started my 2022 Honda Pilot special edition (VIN: [xxx] ) in a parking lot, the vehicle immediately behaved abnormally. As I attempted to turn into a space, the car unexpectedly accelerated and moved in an unintended direction. Despite pressing the brake pedal firmly, neither the standard brakes nor the automatic braking system responded. Shifting into park did not stop the vehicle, and the transmission did not engage to hold the car. The vehicle continued moving through the parking lot, striking property and other vehicles. The entire event felt like a loss of braking and control, with both the brake system and gear selector failing to function as intended. This was a sudden and dangerous incident that could have caused serious injury. The Honda dealer has confirmed there are no open recalls or campaigns for my VIN, but the event aligns with reports of unintended acceleration and brake failure in other 2022 Honda Pilot vehicles.
