On 2/19/2026 I was taking an freeway exit ramp from I 15 south to Carrol Carrol canyon and I stepped on the brake but the car did not slow (my perception was it was speeding up), the vehicle collision warning did not sound and the vehicle did not emergency brake, therefore I hit a stopped vehicle at a stoplight. The air bags did not deploy. Attached pictures: Left side is the vehicle was rear ended. Right side is the Honda Prologue

At approximately 6,000 miles the vehicle started making clicking noises when making a left turn, which then progressed to clicking when making left and right handed turns. I took the vehicle to the dealership and they stated it is a manufacturer defect and there is no recall at this time. When backing the vehicle up it slams the brakes on when there is no reason for it to. The vehicle has also slammed the brakes on when driving down the road and there has been no obstructions or obstacles.

the automatic emergency braking system in both forward and reverse is to sensitive and violently slams the brakes when there is no risk of a collision. the most recent incident involved making a left hand turn where there was a little overpass wall on the passenger side of the street i was turning onto. with cars behind me the vehicle slammed the brakes as i was going approx 10-15MPH, startling myself and all 3 passengers and almost causing me to be rear ended. the vehicle also slams the brakes in reverse when there are no objects in the way predominately if it is raining out. it's a harsh violent stop and can cause an accident or injury. due to this incident the vehicle is back at the dealership for a total of 3 appointments and 32 days in repair for this issue and they still have not remedied the issue

While driving my 2024 Honda Prologue, the automatic emergency braking system (part of Honda's Collision Mitigation Braking System) has activated unexpectedly and forcefully multiple times -?" with no obstacle or vehicle ahead. The most serious incident occurred on 6/28/2024, while traveling at approximately 70 mph. The vehicle suddenly slammed on the brakes without warning or any visible threat in the road. We did not crash, but the vehicle behind us narrowly avoided rear-ending us. This also happens about 50% of the time we reverse the vehicle. Given the potential severity of this defect -?" especially involving passenger injuries and potential crashes -?" I am deeply concerned. Many other Honda owners have reported similar phantom braking behavior across multiple models, and I believe this defect needs to be investigated urgently by NHTSA. Honda has not issued a recall or provided public guidance on how to disable or address the system, leaving drivers at risk.

I got in my car and received the following error messages immediately upon turning on the car: - Brake System Failure 43 MPH Max Speed - Brake Assist Failure. Press hard to brake. Speed limited. - Service Stabilitrak - Auto Hold Unavailable Driving the car was very unsafe as the brakes were extremely difficult to engage, taking my full body force to fully depress the pedal and have the brakes slowly engage. I have taken the car to my Honda Dealership, which (at this time) has been unable to replicate the issue or find a problem. This is a safety issue to have unresolved, as the brakes suddenly becoming extremely difficult to work makes the car unsafe to drive.

The most serious incident occurred on [insert date], while traveling at approximately [insert speed] mph. The vehicle suddenly slammed on the brakes without warning or any visible threat in the road.

Driving in the express lanes south of Atlanta in the rain, the vehicle's Automatic Emergency Braking system activated for no reason. There were no other vehicles around, and we were on a straightaway. It was such an abrupt deceleration that if another vehicle had been tailgating me, they probably would have run into me.

- Atlanta, GA, USA

When I was taking my Prologue in reverse and will slam on the brakes even when there is nothing behind me. It happens frequently nothing behind me. As others have reported here and elsewhere online, my Prologue emergency braking/collision detection system repeatedly activates when there is no danger of a collision. Backing out of my driveway I can expect that 40% of the time the car will slam on the brakes for no reason and apply the parking brake, which I then have to disengage manually to continue backing out.

- Apex, NC, USA

When I put the car in reverse the automatic emergency braking system engages multiple times. Though there are on abstracts on the path. I have to constantly keep pressing the parking brake multiple times in order to get out of my driveway in the morning and afternoon. This is a constant occurrence weather there it is raining or not raining.

During a storm when backing up out of parking spot the prologue did an emergency breaking procedure, engaging the parking break. (There was no one behind me or anything in the way) and left me stuck in the middle of the street until I could figure out what happened. I had to manually release the parking brake and as I did that, I then almost ran into someone that was trying to go around me while I was a full stop. Since this happened randomly, I was not fully sure what was going on. This creates a huge safety hazard when there is no reason for it. There are many reports of this in forums that say just turn it to warning only mode, which then removes a safety feature that 1, was paid for and 2 could actually prevent a accident

When I turn left or right from a complete stop it makes a clicking noise. I believe it is the CV joints. When backing the car randomly puts on the break with nothing around the rear of the vehicle.

Break failure on highway causing MVA- multiple attempts were made to slow down and break vehicle to no response what so ever. Pressed breaks all the way down, nothing, no air, no resistance, no sounds, vehicle kept on going. In an attempt to save myself from an accident that could have been much worse, I jumped out of the moving vehicle, landing the back of my head on the cement highway floor toward left end of bumper. This vehicle is not safe and should be taken off the roads. I have 2 toddlers and am traumatized. The vehicle stopped after some impact in the middle of the highway. From the moment of receiving this car there has been some sort of issue with it's breaks. Initially short stopping on it's own when gas peddle not pressed- had the setting fixed for that to then experience multiple whiplashes for no reason while driving. Attempted to connect the starlink on multiple occasions as well to no success and just a bunch of wasted time trying. In addition to all the alarming safety concerns, this car would not heat up well- 40 minutes into my ride I'd start to feel some warmth. I would love to have this case investigated further and sue honda for allowing such a dangerous vehicle on the roads. My accident was bad but the honest truth is that it could have been worse and no one should have be subject to this danger.

Every time this car comes to a stop, it rocks back and forth significantly on its suspension. Even at low speeds, it is noticeable when breaking, with about a second and a half of five to six rebounds back and forth. It is highly prominent with stronger braking or stop-and-go traffic, resulting in about two seconds of hard rocking back and forth. This problem happens more when the car is being driven in normal mode, meaning using both the acceleration and brake pedals; it-??s less pronounced when driving in -??one-pedal-?? mode. I took the car to the dealer service department, and they tested my car and other Prologues. The service department manager said this seems to be a problem in all the Prologues, even a 2025 model they tested. This problem is causing motion sickness for me and my wife, which can lead to distractions and potentially unsafe behaviors as explained below: * Distraction: Passengers experiencing motion sickness may be too focused on their discomfort to pay attention to the road or the driver, which can be dangerous. * Nausea and Vomiting: Nausea and vomiting can cause a passenger to become ill, which can be a distraction and potentially lead to unsafe behaviors like reaching for a trash bag or losing control of their body. * Safety of the Driver: If a passenger struggles with motion sickness, the driver may be distracted by the passenger's discomfort, which can lead to unsafe driving behaviors. * Increased Risk of Accidents:If a passenger becomes ill and the driver is distracted, the risk of accidents increases. Even though the dealership acknowledged that this seems to be a widespread problem based on the tests that their service department did, they are unwilling to take action until an official recall is in place. Please help.

All lights related to brakes lighted up on a dashboard ( and message to take it to Dealer). Took it to Dealer. Car is in the shop for over 5 weeks and they can't figure it out what's wrong. They've replaced brake booster (twice!!!!!) and that didn't fix it... Now replacing front calipers. On top of that cv axle is clicking terrible and they can't replace it because it's on long Backorder ( I'm waiting over 2 months for it already.

Also the rear brakes engaging with no obstacles on the way.it felts like I hit something. took to the the dealer of purchase and very much make me field like I was insane. and what the technician did was turning off the automatic breaking system. that was the solution. now at when I turn right of left it makes a ticking noise on the suspension. started at 4k miles. plus a win noise is so heavy that I need to the radio volume. I got this car because of the automatic breaking technology offer, but I can't utilize it do to the failure of the system.
