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.
2024 Honda Prologue driver assistance complaints
Page 3 of 7: complaints 41 to 70 of 168, newest first, as owners wrote them.
CV joints left and right make very loud clicking noise, the service department at the dealer ordered the parts in December of 2025, i have been at the dealer twice and today February 6, they told me that the parts are not expected until the end of March, I do not feel safe driving the car. Also the auto emergency brake does not work properly when backing up, false positive hard brakes happen all the time.
Backup Camera Failure (Occurred at approx. 1,000 miles) Part was on backorder, the rearview camera remained inoperative for approximately 99 days (February 22 through May 31, 2025). This rendered the vehicle non-compliant with federal rearview camera safety requirements. Emergency Braking System Issues (Ongoing) Compounding this, the vehicle’s emergency braking system would activate erratically and without cause, including: •When entering or exiting my driveway •During normal lane changes •When driving near trucks or concrete barriers Because these events occurred repeatedly and unexpectedly, I was forced to disable this safety system to avoid sudden braking events, further compromising vehicle safety. Broken CV Axles (Officially diagnosed at approx. 6,000-7,000 miles) •On May 31, 2025, the vehicle was returned to the dealership for backup camera installation and to revisit the knocking noise, this time properly documented. •That same day, both the left and right CV axles were diagnosed as broken, and I was told the vehicle was not safe to drive. •I had unknowingly been driving in this unsafe condition for almost three months. •The vehicle remained in the dealership’s possession until June 5, 2025 (6 days), Recurrence of Knocking Noise and Third Service Visit (January 10, 2026 – Approx. 15,000 miles) At approximately 15,000 to 16,000 miles, the knocking noise had returned (in both directions of steering) and I brought the vehicle in to be diagnosed •The dealership acknowledged hearing the noise. •I was told the sound is a “well-documented issue” with this model and considered “normal.” •I was informed that the vehicle was safe to drive. •I was told Honda is working on a redesigned part and that a recall is expected in approximately six months to one year. •I was specifically told Honda will not authorize replacement of the same axle parts again, as they continue to fail, and that I must wait for a recall remedy.
Every day when backing out of the driveway the car activates the rear emergency breaks as it “sees” my neighbors parked truck across the seat. At no point is my car anywhere near th parked truck. Also, the emergency brake activates multiple times.
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 automatic emergency barking system suddenly applies even when there are no obstructions. Happens regularly. I was almost rear-ended at a stop light by another vehicle because of the sudden application of the emergency braking system, even though there was nothing in front of me. Axel makes a loud cranking sound when making a right or let turn. Battery 'Service vehicle now' warning consistently comes on with warning to reduce acceleration even when the vehicle is not in motion.
Three major problems stand out: faulty CV joints/axles that produce loud clicking or knocking noises when turning, false activations of the automatic emergency braking (AEB) system, which I had to turn off, and high-voltage system failures that can disable charging or limit performance. Other concerning issues include steering malfunctions, infotainment system blackouts, USB-C not connecting, battery not charging to 300mi range, forward collision sensor false activation, and braking anomalies.
CV joints clicking when turning Service eCall keeps coming on Warning light on next to battery range with an exclamation point over the car. The manual indicates its a system malfunction that can be related to vehicle stability assist (VSA) electric power steering (EPS). My safety has not been put at risk. I am scheduled to have the car inspected and repaired on 1/19/26.
Cv joints since 800 miles had new one put in at 9089 miles. Clicking starting happening again about 1,000 miles after repair was done. My car is currently at 12,000 miles and its worse than its ever been. I called the dealer and waiting for a call back. The next is AEB system. My car will suddenly go through all the motions of emergency braking at a stand still. I also get the beeping on the highway and there is nothing in front of me or around 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.
On at least 3 occasions my car has braked automatically for no reason. Nobody was in front of me or behind me.
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.
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.
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.
Blind spot warning works intermittently. Sometimes it alerts correctly, sometimes it does not alert at all, and sometimes it alerts to nothing. This is a huge safety concern because I might try to change lanes directly into a car in my blind spot if it says nothing is there. This was brought to the attention of the dealership, was reproduced for them, and has been confirmed as an issue with my Prologue. Then they just shrugged and said the Honda has not issued a fix for the problem.
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.
The lane keeping assist on my Prologue does not work. It does not engage. It does not attempt to center the car. It never turns on. This has been brought to the dealership's notice, was reproduced for them, and confirmed to be an issue for my Prologue. The dealership then shrugged and stated that Honda has not issued a fix for the issue. This is a safety issue because it is a safety feature of the vehicle and it does not work.
This feature does not work. On roadways with clearly marked yellow and white lines, the system will not read that there are lines on the road. Conversely, on roads with no lines, the system will randomly beep, alerting me to a lane departure from a space with no lanes. Sometimes it just beeps out of the middle of nowhere seemingly because it feels like it. I have alerted the dealership to this. The issue was reproduced for them and they confirmed that the lane departure system was not working in my Prologue. Then they shrugged and said that Honda had not issued a fix for the issue. This has been addressed more than once with no way to fix the issue offered by the dealership or Honda. This is a safety issue because this is part of the safety system in this vehicle and it does not work.
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.
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!
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.
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
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.
