2024 Honda Prologue

When the vehicle is in reverse, the safety feature that is supposed to prevent you from hitting something mistakenly goes off when there is nothing there. It seizes the car and immediately causes the brakes to go off. The car will feel like it got in a crash. There is no way to un-release it and there is no way to change the settings to prevent it. It is a great safety feature that could really protect me from getting into a crash. But instead at least once or twice a week it simply prevents me from backing out of my driveway in the morning to go to work. Delaying me by 1-2 minutes every day. Very annoying.

The automatic emergency braking (AEB) system or collision avoidance feature in my 2024 Honda Prologue has malfunctioned. The car abruptly applies the brakes when backing out of my driveway, and also engages when driving forward and getting too close to other vehicles or when changing lanes, even when there’s sufficient space. The braking is sudden and forceful, making it difficult to control the vehicle. This issue poses a serious safety risk, as the car’s automatic braking can cause me to be rear-ended by vehicles behind me when stopping unexpectedly. The system may also cause a collision when changing lanes, as the sudden deceleration could lead to a crash. The problem occurs consistently, and can be reproduced each time I back out of the driveway, approach a vehicle too closely, or change lanes. The vehicle has not been inspected by the manufacturer, dealer, or insurance, and I have not yet brought it in for service. I am filing this report to document the issue as a potential safety concern. There are no warning lights or messages on the dashboard when the issue occurs. The braking happens without any prior indication from the vehicle, and I only notice after the fact that the system has engaged. This problem began right from the start, within the first 50 miles of driving the car. As of now, the car has about 5000 miles on it, and the issue continues intermittently.

On multiple occasions the forward collision warning and automatic emergency braking have engaged when there is nothing in the lane. On one occasion, the system engaged brakes very hard - which I can only assume was triggered by a pedestrian on a nearby sidewalk. I was traveling 30mph and the vehicle came to an abrubt stop. Traffic behind me was then also forced to slam on their brakes and I feel this could have easily lead to a collision if the driver behind had not been attentive. On another case the vehicle engaged brakes while traveling at 60mph on a two lane highway. I was traveling straight, approaching a rightward bend in the road. My steering wheel was still straight ahead because I had not yet reached the turn. Meanwhile a vehicle was coming the opposite direction around the bend. I believe the system engaged because I was steering straight toward the other vehicle - not taking into account the fact that my lane would bend before reaching it. In this case the system did not stop the vehicle but it did cause a rapid change from 60mph to 40mph in a section of road with no obstructions where neither myself nor drivers around me would expect my vehicle to slam on the brakes. Had the surface been slick such a maneuver could cause loss of control. Again - had drivers behind me not been attentive - I could have been rear ended.

While driving on the highway with no one in front of me, the car unexpectedly slams on the brakes. This issue consistently happens at a specific part of the highway where there is oncoming traffic and a slight incline. It seems like the sensors may need to be reconfigured. Additionally, when backing out of my driveway, the car struggles with snow or ice. It mistakenly detects an object behind me and automatically applies the brakes. To override this, I have to hold the gas pedal. It also doesn’t handle ice reflections well.

The automatic emergency braking system that works with the rear cross traffic warning is not functioning correctly. It is available for inspection upon request. The braking system brakes when reversing even when the way is completely clear. Its as if it sees a shadow and hard brakes. The jerking motion feels like you hit another vehicle. The problem was not reproduced when i brought it to the dealership but the service center did acknowledge it's an issue but there isn't any fixes available at this time. There were no indications for this issue prior and the only way to avoid this is to turn this safety feature offf.
