2024 Honda Prologue Driver assistance Problems

I own a 2024 Honda Prologue (VIN: [XXX]). Since approximately XXX, the vehicle has experienced recurring failures involving critical driver-assistance and safety systems. The problems include: • "Forward Collision System Unavailable" warnings • "Adaptive Cruise Control Temporarily Unavailable" warnings • Automatic braking while reversing when no obstacle is present • Repeated loss of confidence in the operation of safety-related driver assistance systems   The vehicle has been presented to authorized Honda service facilities approximately four times for diagnosis and repair. The vehicle has spent approximately 20 to 22 days out of service. Despite multiple repair attempts, the problems continue. The vehicle has never been involved in a collision. A prior insurance claim involved hail damage only and was repaired. I do not believe the hail damage is related to the recurring failures of the driver-assistance systems. Because these systems are intended to help avoid collisions and improve vehicle safety, I am concerned that their repeated failure may create a safety risk. The unexpected braking while reversing is particularly concerning because it occurs even when no obstacle is present. I have opened Honda Case Number 162-31526 with American Honda Motor Company and have requested assistance, including consideration of a repurchase, replacement, or other resolution. I am submitting this complaint so that the issue can be documented and reviewed as a potential safety-related defect.

While getting ready to parallel park the car, the entire screen system (dashboard, center console) went completely blank. This completely eliminates visibility to all safety aids, speed of vehicle, and warning systems. This has happened with this specific vehicle in the past, and the vehicle has been updated by Honda dealership. it has not been brought to a dealer quite yet. I am awaiting the dealerships opening and availability of a loaner vehicle. I have an ongoing case with Honda on this vehicle, Case # 16062775.

I was traveling on Interstate 80 with adaptive cruise control set at 70. The cruise control normally recognizes slower cars ahead and slows or stops as necessary. I saw that cars were stopped ahead so I reduced the cruise control setting to 60 to "help" it slow down. However, we came up fast on the stopped cars and the car did not slow. I had to manually brake to avoid a collision. The car's speed was about 67 when I applied the brakes. The car acted like slowing to the new cruise control setting of 60 was overriding the collision avoidance. I recently had much of the software in the car updated due to a recall and the adaptive cruise control seems to be acting differently now. Weather was clear, around 4pm, and the roads were dry. We were Eastbound around a slight left curve (not sharp) and traffic was stopped ahead in all 5 lanes, so the system should have noticed the obstacles ahead.

WHEN I USED ADAPTIVE CRUISE CONTROL, MY CAR TENDS TO LEAN SLIGHTLY TO THE RIGHT. IT VEERS OVER A BIT AND THEN JERKS TO THE LEFT. ALL IN ALL, I CAN'T USE ADAPTIVE CRUISE CONTROL ON THE FREEWAY WITHOUT PAYING ATTENTION. IT IS GENUINELY DANGEROUS IF VEHICLES ARE DRIVING ALONGSIDE OR BEHIND ME. OTHER THING, WHEN I USED ADAPTIVE CRUISE CONTROL FOR ALMOST ONE HOUR, THEN IT SUDDENLY BECOMES INACTIVE. IF I HAVE BEEN FOLLOW ANOTHER CAR, then what should happen when it suddenly becomes inactive??? I was very lucky at that time because there was no car in front of me. After 5,000 miles, my car began to make a slight noise on the right side when I slowed down in the city. Maybe it happened in the front drive axle assemblies or the front right low arm control.

Component: Honda Collision Mitigation Braking System (CMBS/AEB). Vehicle is in GEICO insurance claim process, not yet released. EDR data has not been extracted and is available for inspection if preserved before the vehicle changes hands. Safety risk: Two failure modes. (1) False AEB activations occurred multiple times — while driving at ~20 mph and while reversing at low speed, with no obstacle present. Hard sudden braking with no warning created rear-collision risk. (2) On 6/23/2026 at ~9:50 AM, AEB failed to activate when I struck a parked vehicle. Airbags deployed on impact, briefly incapacitating me. My foot remained on the accelerator. Standard post-collision safety design calls for automatic power cutoff and brake application after airbag deployment, specifically to prevent continued acceleration when a driver may be incapacitated. This vehicle did neither — it continued accelerating, significantly worsening the collision. I sustained soreness and bruising. Dealer confirmation: I did not take the vehicle to a dealer for the phantom braking. Per other NHTSA complaints for the Prologue and Honda's broader CMBS issues (Engineering Analysis EA25002), dealers have reportedly been unable to replicate the issue and told owners the behavior is normal. Inspections: GEICO assessed the vehicle for the claim. No inspection by Honda or independent mechanic for AEB specifically. EDR data not yet extracted. Warning indicators: During false AEB activations, the collision warning appeared on the dashboard at the moment of braking, not before. No advance warning. No persistent warning lamps or diagnostic messages indicating CMBS malfunction at any point during ownership. Phantom braking occurred intermittently throughout ownership.

My 2024 Honda Prologue (VIN [XXX]) only has 16K miles on this vehicle. Both front half-shaft CV joints are failing and have been failing for the last SEVERAL months by manifesting a persistent and worsening very loud clicking when loading and unloading the drive-train, driving up hill and executing any type of turn maneuver. I've complained numerous times to the Honda Dealership here in Seattle start 4Q 2025. They informed me that this has been an ongoing "known" problem with this specific model over the entire model 3 year offering from 2024-26, but at that time Honda America had no revised part number to effectively mitigate the problem. They initially replaced the failed CV half-shafts with the same part number, only to have those parts fail again. Honda America subsequently instructed all Honda dealerships maintenance depts to stop replacing these parts until a newly revise part number is released. I was instructed to contact Honda America at their national customer service at 800-999-1009. (My Case # [XXX]). I've spoken with at least 20-30 difference Honda reps over the last 6 months with no commitment to do anything to fix this potentially dangerous problem. When the outer CV joint completely fails, it could potentially turn into a pole-vault stick and literally flip the car at freeway speeds and definitely cause a catastrophic loss of control at freeway speeds or at any velocity/momentum whatsoever. The very disappointing fact is there is NOW a revised/vastly improved Part Number (Honda Part #86284282) that offers customers a fix to this very well known problem. Honda has not officially issued a recall so dealers are not able to perform this fix under warranty. My friend has this same car and her 2024 Honda Prologue is making this same exact clunking noise. She's faced with the same dilemma. Please, we all need your advocacy to get Honda America to act, not to cower and ignore the issue. Thank you for your advocacy!

I was driving on the highway and there was traffic I was good 2-3 feet goin away from the car infront of me and going 10 mph and the automatic emergency break went off giving whiplash and anxiety since the breaking is so impactful. I had turned of about a month ago so I don’t understand how it turned back on

Description of Safety Defect: The Automatic Emergency Braking (AEB) / Forward Collision Avoidance system is severely malfunctioning. On multiple occasions, the vehicle has experienced "phantom braking"—abruptly slamming on the brakes for no reason whatsoever. There were no obstacles, pedestrians, or vehicles ahead to trigger the system. This malfunction is happening at high speeds on major highways. Safety Risk and Impact: This issue represents an immediate and terrifying safety hazard. Unexpectedly slowing to a sudden stop at highway speeds completely compromises vehicle control and leaves me at an extreme risk of being rear-ended by high-speed traffic. It is a severe danger to myself, my passengers, and every other driver on the road. While the vehicle is currently subject to a manufacturer recall regarding the backup camera and other software updates, this specific, dangerous braking behavior makes the vehicle incredibly unsafe to operate. I request that the NHTSA review this issue immediately to determine if a broader safety investigation or expanded recall is required for the 2024 Honda Prologue.

I have had two safety issues with this vehicle where there were system failures that did not record DTC codes. And an additional failure that does not record codes and cannot be duplicated. After leasing the vehicle for seventeen months, and during repair for an unrelated non-safety issue, it was discovered that the steering wheel airbag had a loose connection. No warning appeared at any time on the instrument panels. As well the one pedal function would switch into regular drive mode, as in a gas powered vehicle, randomly. After multiple tries and incidents the dealer service department has been unable to duplicate. Then on March 6 of this year I bought in the vehicle yet again for this one pedal failure, and was notified there was an existing recall. This software update was performed. On March 17, just 11 days after the update, while backing into my garage with the garage door going up the windshield wiper was clipped by the door, destroying both the wiper and shattering the back window. I have backed into my garage thousands of times and never had an issue. Why this happened on this date I do not know. What I do know is that the vehicle gave no warnings and did not break for the object. At the time my dogs were clipped into their seat belt harnesses in the center well. By a miracle no glass shattered beyond the back storage area and I was able to safely remove them. I checked after and all of the collision warning systems were listed as active, including automatic braking for rear collisions. I had the dealership run scans twice and all scans showed no DTC codes and all systems active. I can only assume that all prior updates have failed, and there is a substantial defect to the vehicles ability to communicate. I have a copy of the scan performed. The second scan was run on April 9 because the dealership failed to provide a printed copy of the first. I have that second scan. My vehicle fails to communicate or activate essential information, a safety hazard.

The issue I'm experiencing with my 24 Prologue is the infotainment screen (which controls a lot of the vehicle) sometimes having issues showing the backup camera, or issues with the car not allowing me to utilize ACC (says temporarily unavailable), etc. I feel less safe in the vehicle as a result. The issue is an OPEN recall and the dealership I've contacted 5x [XXX] ) has refused to do the update to the vehicle for various reasons, the most recent being: Honda has not delivered the update needed to the dealership for them to do the work.

Forward collision assist keeps turning off, saying the front camera needs to be cleaned. Loud cracking/clicking/popping noises from front suspension making low speed turns (left and right). Sounds like the wheels want to fall off. I got this Prologue with 4 miles on it, started making those noises at less than 3K. It sounds so bad! Honda seems to be waiting until someone is seriously injured to fix this issue.

The lane keep assist has never worked. It doesn't not keep you in the lane, it just chimes when you drift out of it. The bigger issue is the axles. I only owned the car for 1 month when the axles started loudly clicking with every turn. Honda is claiming this is just a cosmetic defect and it does not affect safety, but I don't believe that for a second. Clicking axles are NOT normal, and could only indicate signs of deterioration. Not only that, but myself and anyone else with this issue can feel that the drivability is affected. Turns and propulsion are slower as time goes on and the clicking gets louder. Honda knowingly continues to sell these cars for up to $60,000 and no longer offers a remedy for the faulty axles. They now plan to discontinue the vehicle and offer no further support for it, which is completely unnaceptable. This safety defect must be remedied as soon as possible. We should not wait until someone is dead.

Shortly after purchase, I observed damaged/torn underhood insulation and reported the condition to the selling dealership, with concern that the vehicle should be inspected for related issues. Prior to a crash incident, I experienced concerns involving braking-related behavior and advanced driver assistance features, including lane assist and object/collision warning functions. During the crash, while reacting to a roadway hazard, the vehicle swerved and struck a pole, and I did not experience warning or intervention from driver assistance features as expected. Following the incident, a diagnostic pre-scan identified multiple faults involving brake control, radar sensors, image processing, and communication systems. Since the incident, similar concerns have continued, including recurring braking/driver assistance concerns, and the issues remain unresolved. I am submitting this complaint due to concern that braking and advanced driver assistance systems may not have functioned as intended and may present an ongoing safety risk.

On April 5, 2026, I was stopped at a busy intersection waiting to turn left. When I proceeded through the light, the car's sensor suddenly went off and the car braked violently. I thought I had hit something in the road. (I was driving in one pedal mode). There was nothing in the road, and I had not collided with anything. The car just decided to brake because it incorrectly sensed something in my way. I was almost rear ended, and it was very frightening. My safety was at risk as well as the person behind me. I have an appointment with the service department at the dealership to address it. This car has been in for service 5 times in the 18 months I have leased it. I have complained to the dealer multiple times, and they have basically ignored me.

Direct cause - Unknown. What I do know however was that the automatic emergency break system on my vehicle was activated, causing the vehicle to stop in the middle of driving. This resulted in the vehicle behind me hitting my car. Prior to the incident occurring, no warning indicators (lamps, messages, etc.) came from the dashboard. The vehicle just stopped. Immediately after this accident occurred. I turned off the forward collision safety feature, as I was scared of the issue (vehicle stopping) repeating itself. To date, my vehicle has not been repaired or my insurance agency contacted, as I do not believe I should be held responsible for the cost of this repair.

The front axle makes a grinding and click sound whenever you're turning. Dealership replaced the part but then the new one just broke as well. Now Honda is refusing to replace again as they supposedly work on a fix that has been well over a year in the making now. Separate problem with the adaptive cruise control. It randomly slams on the brakes on the highway. Dealership agreed they experienced it but nothing they could do and I would just have to wait for a software update and hope it fixes the problem.

Clicking noises when turning. Dealership no longer fixing (fixed passenger side, driver side still unrepaired). Front end collision breaking happening at random, causing unsafe breaking in the middle of the road. Also frequently happening when releasing break at stop light, narrowly avoiding multiple rear end collisions due to breaks being slammed on by vehicle collision system. Now with high voltage battery failure message, blowing cold air out of hvac system and performing at reduced acceleration.
