2024 Honda Prologue

This car has a problem with the emergency brake system activating when there is nothing in any danger zone. We have owned this car for about a year, and when slowly reversing, we have been repeatedly annoyed by the warning lights & sounds going off & emergency brakes locking the wheels. Each time we check the cameras, mirrors and even get out of the car to look, but there was nothing anywhere near that would trigger such an event. This happened 4-5 times over the past year, and we assumed this was just an ultra-sensitive feature which was annoying and startling when it happened, but generally harmless. Until a similar issue with the brake system happened recently while we were coming to a stop while driving forward, except this time after the warnings went off and brakes locked, the car then shot forward, with my foot still on the brake, and hit the car in front of me. Then it locked up and shot forward again 2 MORE TIMES. I've detailed that event in another complaint on this site, but I wanted to put the original emergency brake problems on the record, in case they end up being related.

I was driving a 2024 Honda Prologue Elite and was coming to an ordinary stop at a safe distance behind another car at a red light. With my foot continuously and firmly pressed on the brake pedal, a brake alert/warning appeared on the dashboard screen accompanied by beeping, and the emergency brakes automatically engaged, stopping the car abruptly. Then, almost immediately, the vehicle suddenly lurched forward without warning, striking the vehicle ahead of me. I kept my foot firmly on the brake as the warning, beeping, and auto-brake activated again, and the vehicle lurched forward a second time, again striking the vehicle in front of me. This sequence repeated a third time with the same warning/beeping/braking and lurching pattern, causing a third forward impact. The vehicle came to a stop between each lurch, and at no point did I remove my foot from the brake or touch the accelerator pedal. There were no other witnesses besides the other driver involved, and no police report was filed at the scene. I believe this was caused by a major vehicle malfunction, not driver error. Upon further reflection, I want to note that while I believe I was in the last moment of coming to a complete stop, I had already slowed appropriately and was on track to stop fully, as intended. But because the onset of the malfunction was abrupt and disorienting, I cannot state with certainty whether the vehicle had reached a full stop or was a brief moment away from it when the auto-brake engaged. My foot was firmly on the brake throughout.

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.

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.

On XXX Me and my son were in [XXX] in one of the basement garages. Parked successfully the first time inching the vehicle forward without issues and stopping as needed. 2nd run, got into parking spot got close and stopped 1 foot away from wall. Attempted to inch forward, lightly and quickly tapping on accelerator to disengage auto hold/brake and move forward but car did not respond. Repeated the action, quickly and lightly tapped again no response, then all of a sudden car lurched forward, I jammed on the brakes with no response and car hit the wall. I have my 2024 Prologue at the Gillman Honda Body Shop and gave instructions to service advisor to pull data from my vehicle.

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

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.

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.
