2024 HONDA PROLOGUE Forward Collision Avoidance Problems

On at least 3 occasions my car has braked automatically for no reason. Nobody was in front of me or behind me.

CV joint clicking when turning about 1 month after purchasing the vehicle last year (vehicle purchased 1/4/25). Dealer is aware but said that there is no fix. Still clicking turning both left and right. False emergency breaking system--alerts when there is nothing in front of the car. Has suddenly stopped while driving twice, which is dangerous.

Automatic Emergency Braking often triggers for no reason when backing up this vehicle. This is a safety issue 1) Random stops in a parking lot are disorienting to both the driver of the car and the drivers around them 2) The AEB system creates a very hard stop. During the last incident I was with my father who had recently had neck surgery and had additional pain for about 2 days after the false AEB trigger. Thankfully, it did not trigger any long term complications.

While driving the car this evening, following a day of driving, the info tainment and dashboard screens went blank while on the highway. Pulled off at the first exit (30 miles down the road or so). Tried: - turning car off and on - turning off, opening drivers door for one minute, closing and restarting - the same, but waiting 5 min after opening and closing door - the same, but the using the remote lock to lock the car after closing the drivers door - holding down the radio power button for up to 2 min Drive finished by foijf slowly on local roads. No speed information. No warnings systems available.

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.

When driving with the adaptive cruise control on, the Prologue throws out an alert after it suddenly disengages the cruise control that states that the forward camera is blocked and the cruise control will disengage. The cruise control also fails to notice cars in front of the Prologue and will speed up, then will suddenly "see" the car, jam on the breaks, then the accelerator again. Also, the adaptive cruise control cannot gauge distance between cars and all following distances set for the car, whether 1, 2, or 3, are exactly the same. This has been reproduced for the dealer and confirmed as an issue with this Prologue. The dealer then shrugged and said there were no fixes from Honda yet, so there was nothing they could do. This is a huge safety issue because a sudden deceleration at highway speeds has nearly caused a half dozen accidents in the past 2 weeks alone. This issue has been reoccurring for over 1 year with multiple congerences with the dealership, all ending with the statement that Honda has not issued a fix yet.

This vehicle has automatic emergency brakes repeatedly for no reason on empty roads with nothing around the car. It emergency breaks going forward on the highway. It emergency breaks going backwards out of my driveway. It emergency breaks pulling out of drive thrus. I have nearly been hit multiple times because of this. I have been covered in scalding hot coffee because of this as the car violently brakes suddenly and for no apparent reason.This has been reported, reproduced, and confirmed by the dealer. Then they just shrugged and said Honda has not issued a fix for the issue. This is a safety issue because it has nearly caused multiple collisions on the highway and on city streets.

Forward collision warning either does not work at all or is too sensitive. When demonstrated for the dealership, the warning went off while in park for a potted plant more than 10 ft away, then did not go off again no matter how close the Prologue was moved towards an object nor what speed we were moving, until it suddenly went off as we approached a cross street, alerting to a car that was almost through the intersection before we approached it. The dealership did confirm that the system did not work on the Prologue. Then they shrugged and said that Honda had not issued a fix for the problem. This is a safety issue because it is part of the safety system and it does not work.

I have had multiple issues with this vehicle and it has been in the shop more than 80 days between April and Oct 2025. First, the entire battery system went out in the all electric vehicle. Honda said that since it was a collaboration car with GM, that it would take a long time to fix because their technicians weren’t very familiar. It took almost 8 weeks in the shop before we got it back. Not long after, the entire dash (electronics) went out and the shop had it again for over a week. they never found or could replicate the issue. The vehicle went back in after having multiple incidents of emergency braking when there was no emergency, or even vehicles in my vicinity. The final time this happened, I was traveling nearly 25 miles per hour and the car decided to slam on the brakes, making me feel like I hit a brick wall. My head slammed the steering wheel and my daughter was terrified. I drove it straight to the dealership and they said “what’s wrong with the car this time”…they had it for weeks, couldn’t replicate the issue and tell me it’s fine and to take it home. They suggest TURNING OFF THE SAFETY STSTEM AS A FIX, which seems criminal. The safety features should work properly. I shouldn’t be instructed to turn them off. I am very frustrated and have been working with Honda on a buy back out of good faith, but it’s been weeks and we have no answer. I am forced to drive a gas vehicle, costing me gas money now, when I bought an electric vehicle to avoid this cost. All around, it has cost me more money than it’s been worth and I’ve made multiple car payments as it’s sat at a dealership unusable. Again, it has spent more than 80 days in 6 months at the dealer with no resolution. My sound system blew out last time they had it checking out the braking issue so I waited another week to have that replaced, meanwhile the fix to the braking system was that I was told to turn the safety feature off. Insane

Car shows a turtle image on dash and will not go faster than 30mph nor will it fully charge without dealer intervention. This happens when it's cold. There's also a clicking sound when turning as well that's a whole other issue.

Several issues!! When I turn I hear clicking noises. Last night The "Service High Voltage System" warning lights came on. The Interior pieces are falling off my door and the vent on driver side dash. The automatic emergency break is very strong and jerks very heavily when back up. It’s not turned off!

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

I got several false positives from the radar or perhaps optical system that caused the vehicle to spontaneously and suddenly brake at freeway speeds. I believe it was the optical system that was at fault due to the shifting lines on the freeway but I can't be sure. I got the radio update service bulletin work completed by the dealership and it seems to have abated. However, any 2024 prologue that has not received the update is subject to the same error. From what I understand, Honda has stopped performing the service bulletin at this time due to update failures that have "bricked" the car's software.

My 2024 Honda Prologue has numerous issues. First, the CV joints are making the clattering noises when turning right from a stop. Started at almost 8000 miles, more faintly, but now very noticeable. I noticed the left has now started making the same noises as well at 9000 miles on the odometer. Soon after purchase, the automatic braking/collision avoidance slammed on my brakes HARD while driving at highway speeds. Nothing was present in front of me, early morning and no cars around or I probably would have been rear ended for sure. I disabled the auto braking but the “BRAKE” alert comes on almost daily, with nothing there. Backing up did the same so I disabled it as well. Lastly, every time I use my turn signal to turn right and I bring the wheel back to center, it cancels out as it should but it then turns the left signal on for 3 blinks. Assuming the stalk is to strong or weak and goes back just far enough to indicate like I am going to turn or enter left. This can surly cause confusion to other drivers. The dealer stated Honda is aware of the CV noise but has no remedy at this time. For the other issues, they needed me to leave my car but had no loaner available. I will have to return there at another time as the loaners are “first come first served”.

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.

Forward collision warning system activated Automatic Emergency Braking system and brought car to an immediate stop. This has happened multiple times for no reason. Sometimes it will activate on a street with no other vehicles, today it almost got me rear-ended in traffic.

Frequently engages erroneously due to heavy rain or pavement markings. Last week when it was raining heavily, AEB engaged at least 10 times while I tried to back out of my garage (there was nothing/nobody in my driveway). And this past Friday it engaged 3 times on different colorings for patched pavement cracks in a parking lot while backing out of a parking spot.

I cannot reverse with my car slamming on the brakes and it thinks I'm going to hit something when no one is behind

At almost 20,000 miles my car shut itself off while I was still driving. I was slowing down to a stop but my car was not functioning properly, could not turn my car off, put in park or turn of parking break. I had to sit in the middle of the street for at least a minute until I was able to shut off my car and restart it again. I drove straight to the Honda dealership. Waiting on diagnostic results. Also, I have always had a problem reversing out of a parking space when it rains. The emergency sensor reads an object behind me and automatically breaks even though I am the only car in the parking lot. It takes me minutes to back out enough to turn my car.

1. Infotainment system completely shuts off at random moments and not form of reset will bring them to work again. 2. Forward Collision Warning: Will sound at times even if there is absolutely nothing ahead of you. 3. Lane departure is not always “available at this time”.

Well i bought this Brand New car from HONDA PLANET in NJ UNION 2024 August have been have this issues with axles making clicking noises also when Stopping Suddenly in Reverse this is not normal have been taken to the dealership since i bought this car and its getting crazy for me for my comfort because i bought this car for my comfort use not to be feeling uncomfortable and not safe driving this car

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.

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.

When backing up randomly puts emergency brake on. In return you get whiplash. The car will then not move forward or back have to shut it off. It takes about 3 times for it to work again. The wipes with rain sensing on come on when hardly any rain but pouring and never turn on. The ev does not hold a charge for highway. Trip was 154 I had 280 on charge dies at 145.

Driving in the express lanes south of Atlanta in the rain, the vehicle's Automatic Emergency Braking system activated for no reason. There were no other vehicles around, and we were on a straightaway. It was such an abrupt deceleration that if another vehicle had been tailgating me, they probably would have run into me.

When I put the car in reverse the automatic emergency braking system engages multiple times. Though there are on abstracts on the path. I have to constantly keep pressing the parking brake multiple times in order to get out of my driveway in the morning and afternoon. This is a constant occurrence weather there it is raining or not raining.

When I was taking my Prologue in reverse and will slam on the brakes even when there is nothing behind me. It happens frequently nothing behind me. 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 40% 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.

cuando obtuve el vehiculo a los 5 meses comenso con un golpeteo al girar el volante lo lleve al consecionario y me dijeron que tenia que cambiarle una pieza pero que no la tenian que tocaba esperar un tiempo. pregunte si no habia ningun problema y me dijeron que no que podia seguir conduciendo asi el vehiculo. yo lo lleve en el mes de enero y hasta el mes de abril me llamaron para decirme que la pieza habia llegado. esto me puso en riesgo porque ese golpe cada vez es mas fuerte. alguien externo me dijo que eso era muy peligroso andar asi porque me puedo quedar sin direccion en cualquier momento. el vehiculo nunca me dio una luz de advertencia.mi segungo problema es que cuando voy conduciendo el vehiculo frena bruscamente como si detectara algo en la carretera este es muy sensible y me parese peligroso porque si esto me lo hace en una via de alta velocidad puede causar un accidente, lo mismo pasa cuando doy reversa. este problema no lo he puesto en conocimiento de nadie

During a storm when backing up out of parking spot the prologue did an emergency breaking procedure , engaging the parking break. (There was no one behind me or anything in the way) and left me stuck in the middle of the street until I could figure out what happened. I had to manually release the parking brake and as I did that, I then almost ran into someone that was trying to go around me while I was a full stop. Since this happened randomly, I was not fully sure what was going on . This creates a huge safety hazard when there is no reason for it. There are many reports of this in forums that say just turn it to warning only mode, which then removes a safety feature that 1, was paid for and 2 could actually prevent a accident

Crawling in traffic at low speed 5-10 miles per hour when the auto emergency brake initiated a complete hard stop for no reason. I was not in danger of hitting the car in front of me. Car braked so hard that I thought I had hit something.

Driving very slowly with plenty of distance from me and the car in front of me, car's auto emergency braked HARD. Thought this was a one off but this happened it my other Prologue this week (we own 2) so I decided to report. Scary event that makes you think you hit something and could potentially cause whiplash

Automatic braking is very sensitive, especially in the rain, and even more so when backing up in the rain. The unexpected braking happened to me at a rotary for no apparent reason, and numerous times in reverse. Service Vehicle Soon Light/(Propulsion System Failure) came on randomly at around 4000 miles. Within a day or so it turned off. Nothing with the car seemed to be effected. Then around 4500 symbol turned on again and has been on for a day or so. No notable issues.

Around 500 miles into my lease the CV Balljoint is making a creaking noise. Now the noise extends to both front cv joints and the clicking or knocking sound is all the time, every turn now. Spoke to dealer and they said this is a known issue and they are working on it but nothing so far. In addition, the emergency braking system is too sensitive. On a small bump the car emergency braking kicked in and slammed on the brakes for no apparent reason. This happened over 14 times in the first 3 months. Eventually, I had to turn off my collision braking. Several times I thought the car tires exploded. Dangerous as I do not have control of brakes, steering, etc... everytime this happens.

While sitting idle at a traffic light, my forward collision notification beeped in spite of my Honda Prologue and the vehicle in front of me being completely still. Otherwise, no movement was taking place in front of my car. I captured this on camera during an incident when this occurred briefly. I would be happy for Honda to inspect this. I haven’t reported this to anyone else at this point. No other warning lights or messages indicated this could be a problem. This failure of my forward collision warning system has occurred about 50 times since purchasing this Prologue in late December of last year (over about 7,500 miles). At times, the beeping won’t stop unless I put the car in park. I learned the locations of the sensors behind the rear-view mirror and on the bumper. I cleaned the outer surfaces off to no effect.

I was driving through a parking lot when I received the following warning messages “Brake System Failure,” “Service Stabilitrac,” “auto hold unavailable,” “ Brake assist failure. Press hard to brake. Speed limited.” I then tried to pull over in the parking lot and vehicle was extremely difficult to stop. I had to use both legs on the brake. While sitting waiting on a tow truck, I received another warning message that stated “Service High Voltage System.”

Tried charging my car and says high voltage service , then service vehicle soon light als the tire monitoring system is not working and reverse autobreak is too sensitive

Adaptive Cruise Control works when you set the preferred speed but won't slow down when a vehicle is in front. Tried changing gap adjustments but still not slowing down when there's a vehicle in front. It was completely working while I was driving it in the morning then in the afternoon I almost hit the vehicle in front of me due to my vehicle not slowing down.

Where to begin? not even 2 weeks after having this vehicle it nearly caused a major accident and gave me whiplash & neck problems (have doctors documentation as proof) when the automatic breaking system hard breaked my vehicle twice in the same trip (20 minutes from work to home) with the second time resulting in my car skidding quite a few feet on a highway in the middle of rush hour traffic (want to note the distance in front of the car was quite significant both times) also both CV joint axles need replacing on top of rear passenger door is not the right size & often pops open. Honda dealership has my vehicle for 31 days back in December January stating parts for door would be in within the month and the cv axle would be beginning of march. here it is March 26th and I've heard nothing from the dealership after multiple attempts of trying to get a hold of them. also worked with Honda and opened a claim who also is ignoring my calls. I hardly want to touch the vehicle as I'm afraid of it causing a major accident or the door popping open as I'm driving with my children in the car.

The battery failed at 2k miles and needed to be replaced. Both axles need to be replaced due to failed CV joint. There is clicking with turns. When backing up, emergency braking engages and leads us to stop in the middle of busy roads. This is a safety issue.

The buttons for changing songs have not worked at random times after turning on the vehicle. Also the car has had some problems when it comes to detecting a vehicle in front causing the car to slow down when in adaptive cruise control

What component or system failed or malfunctioned, and is it available for inspection upon request? The emergency break system abruptly activates. It has happened on reverse and going forward. One of the times it happened while on reverse it was raining so I thought that was the issue but it has happened on other occasions too. While going forward it happens when I am in fact getting close to a car however there is no risk of a crash and the system over reacts. Instead of allowing me to break on my own smoothly it goes to a complete stop unexpectedly. How was your safety or the safety of others put at risk? The sudden breaking hurts my neck and back, and that of my passengers. It also puts my car at risk of getting rearended by the car behind me due to the sudden and complete stop. Ignoring the crying children that get scared by the sudden stop and think there has been an accident. Has the problem been reproduced or confirmed by a dealer or independent service center? No. I emailed the sales rep this morning to complain but no response yet. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No.

On 2/16/2025, I was slowly (maybe 5mph or slower) backing out of an Electric vehicle charging stall. Rain was falling lightly. The AEB system activated more than five times in a span of 60 seconds. The vehicle thought there was an obstruction in my path, even though there was no vehicle behind me or in front of me. There was a vehicle that was parked in the other stall charging.

All ADAS systems have to be turned off. Even if switched to alert only the vehicle will randomly break very hard while driving. Also will randomly not allow you to back out of your garage. Or when raining will not allow you back up.

Braking for no reason slam on the breaks so hard we all got so scare. Also the rear brakes engaging with no obstacles on the way.it felts like I hit something. took to the the dealer of purchase and very much make me field like I was insane. and what the technician did was turning off the automatic breaking system. that was the solution. now at when I turn right of left it makes a ticking noise on the suspension. started at 4k miles. plus a win noise is so heavy that I need to the radio volume. I got this car because of the automatic breaking technology offer, but I can't utilize it do to the failure of the system.

I've had to turn off all the safety features in my car on multiple occasions. I nearly got hit by several cars turning into driveways because the car's sensors detected a vehicle on the driveway. Additionally, the sensors mistakenly detected another car pulling out of a shopping center, which caused heavy brake locking. This has even happened to me twice on the freeway. When I mentioned this to the service manager, he laughed and said, "I know what you're talking about. I have one too, and it happens to me as well. Unfortunately, there's nothing we can do about it except turn off the sensors." And be careful with your neck the ways brakes lock in

Very frequent and sudden breaking when no objects or any moving vehicles in the line of sight. This keeps happening and I am not able to use the safe system as is without turning it off

Car braked extremely hard causing whiplash twice even though there was ample room. This has happened multiple times. Reported that it is normal by dealership

I have had my prologue for about two months now and have noticed that I receive a warning about reduced acceleration "randomly." I say “randomly” because I’ve observed that it appears during two specific situations. I get that warning whenever I’m low (less than 20%), so this is not random as it seems consistent. The other time this occurs is when I am driving or just starting my car (the battery percentage doesn’t matter, as it happens when it’s between 30% and 80%. Also, it happens when the temperature is below and above freezing). However, the latter situation occurs randomly and seems to happen more frequently while driving, though it also occurs when I am just starting the car. On top of that, the Forward Collision Warning system is extremely sensitive and has caused the car to brake hard unnecessarily on me with and without Adaptive Cruise Control enabled. Sometimes it even warns me of something that isn't even there.

The vehicle's backup sensors exhibit excessive sensitivity when reversing from a garage or parking space. My vehicle engaged the emergency brakes automatically despite the absence of nearby cars or pedestrian obstacles.

The car makes a clicking noise when I make sharp turns, most co.monly to the left. It is brand new with only 2320 miles on it. The noise started within the last few weeks. The rear breaking system locked up the brakes and turns the emergency break on, when backing up, even if nothing is behind me. Once it was rain drops dripping off of the rear window. Another time, nothing was there. I had to assume that it picked up a shadow in the driveway.

While approaching a red light on a busy road the forward alert triggered and auto breaking was engaged with no vehicle in front. Almost resulted in an accident. Had the light not been red other cars near me may not have been breaking.

I have encountered recurring problems with the vehicle's automatic braking system, as well as issues with the Honda Prologue app, both of which I believe compromise the vehicle's safety and performance.
The vehicle's automatic braking system appears to be malfunctioning, as it has activated unexpectedly on multiple occasions, leading to near-miss accidents. At least three occasions, the vehicle’s brakes have engaged without cause, even in situations where there is no obstruction or “phantom” vehicle detected. This automatic braking has not only been inappropriate but also posed a significant safety risk to both myself and other road users. Additionally, the reverse braking system exhibits similar issues, activating without cause. Despite the alerts being on and the brakes not being engaged, the system’s warning signals still activate, leading to further confusion and potential danger. I have consulted with both the dealership and the Honda Prologue forum, and it has been confirmed that this is an ongoing issue. The dealership has indicated that they have no immediate workaround or solution. The only remedy has been to disable these safety features entirely, which negates the very purpose of having them. 
The Honda Prologue app, which is intended to provide critical vehicle information and allow remote monitoring and control, is also malfunctioning. I have been in communication with Honda for over two months regarding these issues, but unfortunately, no viable solution has been provided. The app is essential for monitoring vehicle functions such as theft prevention, charging status, and temperature control, all of which are key safety and convenience features. In particular, I am concerned about my ability to monitor the vehicle’s charging especially given the increasing number of incidents involving electric vehicles catching fire during or after charging. Proper monitoring of charging status is crucial to avoid potential overcharging and battery degradation.

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 turn i hear a clicking sound dealer technician acknowledges sound but refuses to repair. forward collision system sees things that are not there and slams on the brakes for no reason. hvac system fails to heat until after driving for at least 45 minutes even after pre heating.

Twice, a "service high voltage" error light has come on and it has said it impacts the ADAS and safety systems and the acceleration of the vehicle. The light disappeared after a short drive, but the heating system stopped working. The first time, we took it to the dealership and they reset the system and the heat came back a little, but seems to struggle under 32 degrees, and especially sub 15/20 degrees. The second time was this morning - the heat is barely working at all. Very frustrating for a vehicle under 2000 miles.

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

On several occasions while in reverse the car braked hard and violently for no reason. This caused a sudden jolt to me and the passengers endangering our safety. Also, this condition can cause an accident if I’m trying to back up to avoid a collision and the emergency braking system does not allow me to do such. The vehicle has not been inspected by anyone else and no warning lamps messages or other symptoms of the problem appeared prior to the incidents. This condition first occurred with about 300 miles on the vehicle.

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.

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

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 backing up car will stop abruptly for no apparent reason. This has occurred several time and each time it occurs I think I hit something. It it very annoying and possibly dangerous if car abruptly stops while backing up.

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.

I got the high voltage battery warning error on my dashboard after one random night of charging. The error doesn’t go away after 3 days and at times, the vehicle could not charge. I contacted my salesman and he suggested a hard reset which involved turning off the car and keeping the car fobs at least 20ft away, which worked. However I’m still concerned there is an issue with the battery. The memory seat setting doesn’t connect to the profiles. It randomly picks between 1 and 2 whenever the car turns on. Guest profiles can’t have their name saved unless their Google account is connected. The speaker rattles when volume is higher than 20%. There’s a knocking/clicking sound whenever I steer left or right. I called the dealership on 1/22/25 but was told it is not an issue. The vehicle has about 800mi on it. Front and rear collision warning sensors are too sensitive. The default settings for both are “alert and brake” which had led to random braking when backing out of a parking spot AND random braking when I was driving on the road. Luckily no accidents occurred and I have turned both to alerts only.

With reverse alert and notifications on, the vehicle violently brakes when there is nothing in the way

Received multiple alerts including "service high voltage system", "service vehicle soon", and "cannot charge". The vehicle also reduced speed and function, which could have resulted in reduced driver safety. Vehicle will be brought in for service to determine cause.

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.

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.

Safety issue 1 Automatic collision breaking is too sensitive when going in reverse. The vehicle locked up the brakes several times when I was trying to reverse causing myself and my family‘s heads to snap back suddenly. Safety issue 2 -knocking sound coming from the CV joint when backing up and turning at the same time. This usually happens when it’s cold outside. This is a safety issue because if the CV joint fails, this could cause loss of control of the vehicle while driving.

Whenever it gets cold, the car will being to experience brake systems failure, it was suddenly only go 62MPH. On this particular occasion, the car died in the middle of the street, thus blocking the street and causing a police response. Contacted Honda Support and they advised it would be up to 2 hours to get it towed out of there. Police called their own tow truck, the tow trucks had issues with it not going into Transport Mode and stuck parking break. It was brought to the dealer for repair. I believe the car is not safe because there has been several failures of this nature during the cold and other general system failures that appear to be computer related. More than likely police information item is on file.

The car had an error with a front safety camera, the car stopped in the middle of an intersection and I had to coast into the nearest parking lot. The error cleared it self but Honda was of no help. The dealers do not know how to fix the cars.

Automatic Emergency Braking is too sensitive. I have a one car garage and can not back out of my garage with the feature enabled. It continues to brake and set the parking brake until I disable the braking feature.

Vehicle abbrupted stops when driving with the front collision on. I drive up the same hill everyday and when slightly turning left along a curve going up hill, and if there is a parked car present on the right side of the road, the car will abruptedly stop. If I slow down to less than 20 mph, the car won't stop, but doesn't seem like it should happen at normal driving speeds.

Adaptive Cruise Control and Lane Keeping Assistance was unavailable more than 4 times in one month. Got a propulsion waning light 3 times. On the third time, the dealer ordered a new EV Battery for my Prologue

The automatic emergency front collision warning system is extremely sensitive and will warn you to break incessantly.

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.

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.

Sensors are highly sensitive, particularly regarding rear braking and parking maneuvers. There are never any objects or individuals behind me, yet the vehicle brakes automatically.

When backing up with the auto braking on, the car will sometimes brake extremely hard when there is nothing behind me. Sometimes it almost won't let me backup at all as it keeps thinking there is something back there.

Car will stop abruptly even when simply reversing out of my garage when there are no obstacles behind me. This poses a safety risk to me and others. Car has not been inspected. I was told by the dealer this is a known complaint. No warning lights or messages.

The car just emergency brakes for no reason. This is an issue because what it decides to break one day while another car is near by or I am on the highway. Also, there is a cv joint clicking issue and there was a red car with a ! That popped up too, when I took it to the dealership they were no help.

Car has only 4,000 miles and the CV axels make a grinding noise when turning. Also the emergency braking will randomly go off when reversing the car.

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.

The steering doesn't return to the center after a hard turn. This requires me to manually return the steering to a neutral forward setup. Additionally, when it's rainy, the emergency rear braking is overly sensitive and will randomly activate.

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.

The forward collision sensor failed to work after 2500 miles, disabling my ability to use adaptive cruise control. I've thoroughly cleaned the area where the two sensors are and it made no difference.

Emergency braking in reverse will randomly engage while in reverse when there is no object that is potentially obstructing reverse. This is a safety issue as when it engages, other vehicles around may not be able to react as quickly and cause an impact. This has not been reported to manufacturer, it has been reported to dealer. Warning lamp for emergency breaking engaging and requires to be put in gear and engage manual break accordingly.

The Automatic Emergency Braking system engages without any apparent reason leading to a very dangerous situation since the vehicle abruptly makes a hard stop. This is a real road safety issue.

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.

Specifically, I have encountered recurring problems with the vehicle's automatic braking system, as well as issues with the Honda Prologue app, both of which I believe compromise the vehicle's safety and performance. 
The vehicle's automatic braking system appears to be malfunctioning, as it has activated unexpectedly on multiple occasions, leading to near-miss accidents. On at least three occasions, the vehicle’s brakes have engaged without cause, even in situations where there is no obstruction or “phantom” vehicle detected. This automatic braking has not only been inappropriate but also posed a significant safety risk to both myself and other road users. The reverse braking system exhibits similar issues, activating without cause. Despite the alerts being on and the brakes not being engaged, the system’s warning signals still activate, leading to further confusion and potential danger. I have consulted with both the dealership and the Prologue forum, and it has been confirmed that this is an ongoing issue. However, the dealership has indicated that they have no immediate workaround or solution. The only suggested viableremedy has been to disable these safety features entirely, which negates the very purpose of having them. 
The Honda Prologue app, which is intended to provide critical vehicle information and allow remote monitoring and control, is also malfunctioning. I have been in communication with Honda for over two months regarding these issues, but unfortunately, no solution has been provided. The app is essential for monitoring vehicle functions such as theft prevention, charging status, and temperature control, all of which are key safety and convenience features. I am concerned about my ability to monitor the vehicle’s charging, especially given the increasing number of incidents involving electric vehicles catching fire during or after charging. Proper monitoring of charging status is crucial to avoid potential over overcharging and battery degradation.

While backing up the car will slam on the brakes for no reason. It has done this twice with nothing behind me. Scary when you think you have got something.

Brake system failure happened the day after I bought the vehicle and the dealer found no issues or errors than another brake failure occurred in one week. This could have caused a major accident to a point where my safety is in fear

Parking my car in a space with other cars. Nowhere near the car in front of me and the car just locked up the brakes. It was jarring and really strained my neck as I wasn’t expecting it. My daughter was in the car as well and was jarred.

Automatic emergency braking triggers repeatedly when no hazard is present. The system triggered emergency braking and a close-call accident at an intersection. Cars were parked along the side of the road, presumably tricking the system into thinking there was a hazard. Brakes slammed on with a car directly behind us, almost rear ending us. This also happened when reversing out of our driveway. No hazards present, but the system slammed on the brakes. Only possible cause was shadows. These systems are dangerous and not ready for public use. Please force the manufacturer to fix this before people are hurt.

Brakes activated in an unwarranted situation. Suddenly stopping in the middle of traffic.

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

My Daughter left to go to school and when she got on to the road from driveway both screens on car went out. I had her come home and tried to get the dash to come on by turning car off then back on multiple times and nothing happened. Called Honda roadside assistance to get vehicle towed. Went back to vehicle to try again and the dash was working again. Called Honda roadside to update they suggested still having it taken to shop to be looked at

When backing up rear park assist slams on brakes with no person or vehicle in sight. Incident #2 While driving on the highway all screens including radio and instruments went out leaving no access to range or speed. Had to take to Honda dealer for factory reset. Incident #3 Axels are clicking and shop states are broke and on back order. Vehicle had less than 8k miles on it when issue started.
