What 795 owners told NHTSA about the 2024 Honda Prologue Bev

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.

Unknown braking while no objects in front or behind the car. Warns lane departure too late after you crossed halfway through the lane.

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.

When backing out with ZERO obstacles or things in either direction the car will suddenly come to a violent stop. Had to turn off rear safety camera braking system, as it is useless and dangerous.

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.

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.

NHTSA ODI 11637816

Regularly slams the emergency brakes when reversing out of the driveway when there is nothing there to warrant an emergency brake Additionally, it will not release the brakes for several seconds. I feel this could leave me stuck in the middle of the road and vulnerable to getting hit by an oncoming vehicle.

When I was backing out of a parking spot the rear collision detection went off without any obstructions behind me. Although I was safe this could of caused bigger issues.

NHTSA ODI 11636918

I cannot back out of my garage or down my 20 foot driveway without the car emergency braking 2-3 times. There is nothing behind me. This happens every time. I had to disable the following features. - Park Assist with Braking - Rear Cross Traffic Braking

NHTSA ODI 11636769

The warning system is over-sensitive. Front Collision Warning - The forward collision warning randomly comes on while driving. Once, I was coming to a stop and at least two car lengths away when the system alerted me. Another time, I was driving down the road, and no one was in front of me when the system came on. This is a safety issue to both the driver, passengers, and others on the road because if the car thinks it's too close when it's not, it could violently and abruptly stop, thus causing other vehicles around the driver to crash, too! Rear Cross Traffic Warning - When backing up, the system violently stops the car and throws it into park mode, and there is nothing behind the vehicle. It will do it three times if you try to put it in reverse after being violently stopped. This happens all the time. One time I was in a parking lot with no one around and this happened 3 times before I could safely back up and then drive. The current mitigation is to turn the Rear Cross Traffic Warning off. This is a safety issue because being stopped so violently and abruptly could cause neck and back injuries. This is also a safety issue for others because I have to turn the system off, and there could be an unfortunate accident the system is meant to prevent.

Front axels produce loud clicking and popping noises when turning sharper in both the left and right directions. This first started at 2,500 miles and seems to be getting progressively worse. Vehicle now has 3,500 miles on it. Sound is heard in both forward and reverse. Parking collision activates regularly when backing out of the garage. It aggressively stops the vehicle and will not allow it to move even though there is no obstruction. Emergency braking aggressively activated one time for an unknown reason.

About two weeks into having my Honda prologue. I started noticing a clicking sound. Every time I took sharp sharp turns my steering wheel is not centered. I took it to the dealer, thinking that it was a wheel misalignment. They told me that the alignment was in perfect shape I the steering wheel is still not Centered. when I drive. but dealer said they found no issues.... The rear crossing warning detects a person a lot of times even when there is no person behind the vehicle, it makes a sudden stops. I have gotten whiplash because of how hard the breaking system abruptly stops.

NHTSA ODI 11636510

every time you drive out of our parking garage your warning system will slam on the brakes even if you are not even close to anything....the brake force is extreme and dangerous. extremely sensitive

NHTSA ODI 11636633

When the car is in reverse it will slam on the brakes abruptly while flashing the cross traffic or rear collision warning lights when nothing is there. It’s very annoying and can be a safety hazard especially if it is icy or snowy. I have found myself sliding on ice and snow when in reverse because the vehicle slams on the brakes. I have almost hit things multiple times.

NHTSA ODI 11636644

CV Joint/ Axle. Also, rear collision warning system. CV Joint/Axle makes a very audible clicking sound when accelerating during a turn. Rear collision warning system hard brakes whenever you reverse even when there isn't anything there. the only solution is to disable it. I brought the vehicle to the honda dealership where i purchased it from and they confirmed there's an issue but said it's "normal". they were able to reproduce it The honda dealership inspected the vehicle. The CV Joint/Axle - i didn't notice any issues until i started hearing the sound. it was initially only when making right turns, but now it's heard when making right and left turns.

NHTSA ODI 11636659

The vehicle slams on its brakes during attempts to back up on a random basis. Strong safety concern when parallel parking and it stops several times in a row when it is nowhere close to a car. This also occurs in empty parking lots

NHTSA ODI 11636669

When I reverse, from leaving home at our garage, multiple times the car will apply the brakes. It thinks there is something or someone behind me and applies the brakes to avoid hitting something. I ended up turning off the rear braking setting. I was also cruising along on the highway at 70MPH when the car turned off the the system. It shocked me because I wasn't expecting the gas pedal to be let up. It seemed like the car thought there was another car in front of me even though there were no cars for at least 3/4 mile . It turned off the front collision system. The sensors seem sensitive even though I cleaned the sensor/radar on the front windshield, the front camera, rear camera and the side door cameras.

NHTSA ODI 11636469

The collision system is too sensitive. Regularly when I’m backing into a parking spot the car will slam on the breaks even though there aren’t any objects in the way. This will also happen on occasion while driving forward normally potentially causing someone behind me to rear end the car

Sensors cause unnecessary braking when going in reverse. Happen in rainy conditions.
