2024 Honda Prologue

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! [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION AC

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.

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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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.
