2024 Honda Prologue

On April 5, 2026, I was stopped at a busy intersection waiting to turn left. When I proceeded through the light, the car's sensor suddenly went off and the car braked violently. I thought I had hit something in the road. (I was driving in one pedal mode). There was nothing in the road, and I had not collided with anything. The car just decided to brake because it incorrectly sensed something in my way. I was almost rear ended, and it was very frightening. My safety was at risk as well as the person behind me. I have an appointment with the service department at the dealership to address it. This car has been in for service 5 times in the 18 months I have leased it. I have complained to the dealer multiple times, and they have basically ignored me.

The issues I am experiencing for approximately the past five to six months include:- Forward Collision System showing the message “Forward Collision System Unavailable.” Adaptive Cruise Control displaying “Adaptive Cruise Temporarily Unavailable.” Rear parking safety system applying sudden braking even when there is no pedestrian, vehicle, or object nearby. Even when the system is set to “Alert Only,” the vehicle still applies the brake unexpectedly.

On multiple occasions the alert for either the forward or rear collision warning system will sound with nothing either in front of or behind the vehicle. In these cases, the car automatically braked and brought the car to a stop in the middle of my driving. The component is not available for inspection. This puts myself and others at risk by completely overriding my ability to control the vehicle until I am able to put the car back in gear and begin moving again. It completely immobilizes the car for several seconds. It is also a safety hazard because I have been forced to turn off the automatic braking for both the front and rear collision warning systems. This problem has not been confirmed by the dealer, nor have any of the parts been inspected by those listed above. There were no warnings or messages before the problem began.

When turning my vehicle I hear a clicking & cracking sound in the cv joints of the car. It happens in both directions. This can be a safety issue when driving if the axial or CV joints fail. It could put myself, my family & other people on the road in danger if this happens & the joints go out or fail. NO warning lights it just happened over time. the car has only 14000 miles at the time of this complaint.

The system does not reliably "see" pedestrians or cross traffic or often times will phantom brake when there are no obstacles viewable. I believe this is a substantial safety issue because the car will abruptly stop without warning and engage a parking brake, creating a delay before being able to vacate traffic. This has happened going forward, but more frequently in reverse. This appears to happen more during inclement weather or in the dark.

The parking collision warning will alert and emergency brake for no reason while still several feet from anything near the Prologue. This was demonstrated for and confirmed by the dealership. Then they shrugged and said that Honda has not issued a fix for the problem. This is a safety issue because the sudden emergency brake has nearly caused collisions and has covered me in scalding coffee multiple times.

1. Parking sensors will go off at the most random times. The most common is when I’m at a standstill at a traffic light and the front parking sensors will start beeping as if I am as close as possible or about to hit an o next in front of me. 2. Rear parking sensors consistently alert and beep when there is nothing behind me. For instance I was backing out of a parking spot with no cross traffic or anything behind me. As I was trying to back out it slammed the breaks and came to a sudden stop. It did this again until I pulled the car back into the parking spot and backed out again. This will also happen when I am backing the car into and out of my garage. I don’t have anything beside me or within the guide lines but it will out of nowhere come to a sudden stop and not let me back up anymore. 3. I had one instance of emergency breaking. We were coming to a stop when out of nowhere the emergency breaking stopped the vehicle. We were at a slow rate of speed at this time. Maybe 10mph when it slammed the breaks on to come to a complete stop about 10 yards behind the vehicle in front of me. It did this twice within a few second period causing a motorist behind me to almost hit me.
