I am reporting a serious safety concern involving my Honda Prologue and believe the repeated failures may indicate an unresolved defect involving the vehicle’s electronic, braking, ABS, propulsion, transmission/shift, or vehicle-control systems. On [XXX], the vehicle first displayed an error/warning. I contacted the Honda dealership in Vancouver, Washington, and was instructed to bring it in for inspection. I was out of town and could not do so immediately. On [XXX], I brought the vehicle to the dealership in the morning. They kept it overnight and returned it to me on [XXX] at approximately 2:00 PM, telling me the problem was a “system glitch” and had been fixed. On [XXX], less than 24 hours later, I was driving home after completing a Lyft ride when the vehicle displayed: “One-Pedal Driving Unavailable – Use Brake for Stopping.” At the same time, the ABS warning and multiple other safety-system warnings illuminated.The vehicle then became immobilized in the middle of an intersection. I was in an unsafe location and had to contact police for assistance. The vehicle remained unable to operate for approximately two hours. After multiple restart attempts, it suddenly became operational again, allowing me to drive it to the Honda dealership.I have photographs and videos documenting the warnings. One photograph shows the “One-Pedal Driving Unavailable – Use Brake for Stopping” warning with the ABS and multiple other warning indicators illuminated. Another shows “Service Transmission Now – Unable to Shift Soon.”This is especially concerning because Honda had already been notified, had possession of the vehicle for approximately a day and a half, and told me it had been repaired. The vehicle then experienced a serious failure the following morning and became disabled in traffic. This is not simply an inconvenience. A vehicle that can suddenly become immobilized n intersection presents a serious potential safety I use this vehicle for Lyft INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
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.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
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.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
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.

NHTSA complaint #11746982 — an unverified report by a vehicle owner.
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.

I was traveling at a steady speed of 35 MPH approaching an intersection with a red traffic signal. There was a single vehicle already stopped at the light, but it was positioned a significant distance ahead of my vehicle. Without any warning, driver input, or hazard present, my vehicle initiated an uncommanded emergency braking maneuver. The vehicle forcefully decelerated from 35 MPH to a complete stop (0 MPH) in the middle of the roadway. Prior to this incident, the vehicle's forward collision system has exhibited false positive detections, frequently issuing warnings for phantom vehicles or obstacles when the road ahead was completely clear

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
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
NHTSA complaint #11744385 — an unverified report by a vehicle owner.
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.
