2024 Honda Prologue

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. The sudden stop caused whiplash injuries to my wife and two children, who were passengers in the vehicle. We did not crash, but the vehicle behind us narrowly avoided rear-ending us. I have attempted to get the vehicle serviced, but the nearest dealership told me there is a wait time of over a month, so no diagnostic has yet been performed.
