2024 Honda Prologue

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 25-50% 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. More recently, I was driving 30 mph on a city street with no one in front of me when without warning the Prologue slammed to a complete stop. Fortunately no one was behind me or I almost certainly would have been rear-ended. After four months of owning the Prologue, and seeing this exact problem reported over and over again, it's evident the entire electronics system is glitchy at best and downright dangerous at worst. Everything from the crash-avoidance cameras (regularly issues messages that they're blocked when they're obviously not) to the remote starter (supposed to come on with two quick presses of a button on the fob, but often takes a dozen or more to actually activate) is borderline non-functional. Whether this is a software or a hardware problem, or some combination thereof, there's no question in my mind that sooner or later, as more of these vehicles are on the road, one of these malfunctions is going to cause a crash. I hope the NHTSA will see enough of a quorum of similar complaints to investigate before that happens. For my part, I've turned off all driver assist systems in my Prologue, which is the only way I can be assured the car will only brake when it should. Additionally, again as many others have reported, my Prologue knocks somewhere in the vicinity of the front axle whenever I corner sharply enough in either direction.

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.

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.
