FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

This is my second separate report which I experience with my car. On August of 30th, the car was unable to shift, so it was towed to Andy Mohr dealer to repair. It took 5 days for serviceman to figure out there was a wire issue. So he fixed, so he thought, on the September 9th, the same warning light came on my dashboard. I spent over a thousand dollar just serviceman to diagnose the same problem 3 times, but nothing was fixed. The warning lights are "service transmission unable to shift soon", adaptive cruise unavailable, one-pedal driving unavailable, brake hold unavailable, service emergency brake, service transmission unable to shift and more.

LANE DEPARTURE: ASSIST

1st Continuous clicking sound from the front axel when trying to turn, its amplifies when taking a uturn. I have complained to Honda service center they said they are not aware of while there is already fix done at different honda service centers. 2nd the Lanes assist doesn't work as a safety feature, it has multiple issues a) it ping pongs between the lanes with sudden moves, b) most of the times at the higher speeds it only warns or tries to correct once at least one of the wheels is in another lane c) with adaptive cruise control on and lane assist not working on any curved road if you are close to the divider or near an exit, it doesn't understand that the car ahead has taken the curve and it should stick in the lane, instead it accelerates and goes of the lane and thats very dangerous.

LANE DEPARTURE: WARNING

I have reported car jerks while driving as though pushing to go. Car service said never heard of something with Prologues and brushed it off. I want it documented. The safety features such as listed above do not always effectively work either.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

The warning messages pop-up such as "One pedal Driving Unavailable. Use Brake for Stopping", "Auto-hold unavailable", and "adaptive cruise control temporarily unavailable " then parking sign with ranch sign turns on. And all the functions will be disable. I went to Honda dealer to fix the problem, all they said was Parking Brake Actuators. So they replace both left and right rear Brake Actuators. A week later same messages come on and recently I have new additional warning message on Dashboard. "Service Transmission Now Unable to shift soon", I went to honda dealer, of course there is no warning message show up then, so they cannot scan or nothing showed up on the scan. So they suggest that I kept driving until warning light stay on.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

In approximately early August 2026 (exact date not recorded), while driving my 2026 Honda Prologue Touring at approximately 20–30 mph on a surface street, the vehicle's forward automatic braking system activated without warning and braked hard to a near stop. There was no vehicle, pedestrian, bicyclist, or obstacle in front of me. I was approaching a pedestrian crossing that was empty at the time. Conditions were daylight and warm, dry weather. The deceleration was violent enough that I was thrown forward against the seat belt. My foot was resting lightly on the brake pedal as I approached the crossing, but I did not brake hard — the sudden, forceful braking was initiated by the vehicle, not by me. The vehicle did not come to a complete stop and the electric parking brake did not engage. No warning message or fault light appeared before, during, or after the event, and the vehicle continued to operate normally afterward. This behavior creates a serious risk of a rear-end collision. The vehicle had fewer than 1,000 miles at the time of the incident. It has no open recalls, and the dealer has not yet inspected it.

BACK OVER PREVENTION: WARNINGS

On August 23, 2026, I was backing my 2026 Honda Prologue Touring out of a parking space at a Costco parking lot in Cedar Park. I was reversing very slowly, at below walking speed, and repeatedly applying light brake pressure because of interruptions and pedestrian traffic in the lot. While reversing in this manner, the vehicle abruptly and forcefully applied the brakes on its own. The braking was violent enough that I initially believed I had struck an object. There was no vehicle, pedestrian, cart, or obstacle behind me, and no vehicle was crossing behind me from either direction. Conditions were daylight, warm and dry. The electric parking brake did not engage, and no warning message or fault light appeared before, during, or after the event. The vehicle operated normally afterward. An unexpected hard stop while reversing risks injury to occupants and creates a risk of being struck by a following or crossing vehicle. This is one of two uncommanded braking events on this vehicle; I am filing a separate complaint regarding a forward automatic braking event. Mileage at time of incident: approximately 1,600. The vehicle has no open recalls and has not yet been inspected by a dealer.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

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.
