2024 Honda Prologue brakes problems

Filed Nov 2, 2026 · Brakes, Driver assistance · CA

My 2024 Honda Prologue has repeatedly applied sudden, unexpected braking while I was driving, even though there was no vehicle, pedestrian, or obstruction in front of me. The incidents have occurred at different speeds, including approximately 45 mph and 10–15 mph. The vehicle abruptly decelerates without an apparent reason, creating a serious risk of a rear-end collision and endangering me, my passengers, and other motorists. I have sought assistance from authorized Honda dealerships on multiple occasions. During a previous service visit, certain safety features were disabled, but the unexpected braking occurred again afterward. The problem has continued despite my attempts to have it addressed. On October 9, 2026, I brought the vehicle to San Leandro Honda. The dealership documented my complaint that the vehicle randomly brakes when nothing is in front of it. The vehicle was inspected, but the concern remains unresolved. I am not aware of the dealership successfully reproducing the unexpected braking during its inspection. I have also reported this safety concern to American Honda and requested a vehicle repurchase. The manufacturer is reviewing my request. I am concerned that the automatic emergency braking or related collision avoidance system may be malfunctioning. The exact cause remains unknown. I request that the federal safety agency investigate this recurring unexpected-braking condition because of the potential for a serious collision.

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 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

Please see details of the federal safety agency Campaign #25V433000. This is a known issue associated with a platform technology shared by GM and Honda. I purchased the vehicle as CPO on 31 July and almost immediately the parking brake warning light and the 'Service Transmission Now, Unable to Shift Soon' error code appeared on the dash. I returned the car to the dealer on 1 Aug for repairs and was told this is a 'known issue' with Honda Prologues, but there is no recall in effect for Honda. How is this possible? I am concerned with the degree of risk I could have potentially encountered due to a sudden brake failure or being stranded.

While driving my 2024 Honda Prologue Elite at anywhere from 10-30 MPH, the One-Pedal Driving system suddenly and without warning faults out and disabled mid-drive. The regenerative braking abruptly cut out, causing a sudden loss of expected deceleration, creating a 'lurch forward' feeling. A dashboard warning light illuminated instructing me to press the brake pedal immediately. This has happened multiple times, causing a severe safety hazard during normal traffic conditions. The vehicle shares an identical GM Ultium electronic brake modulator architecture with other previously recalled vehicles. The car is unsafe and should be considered for recall repairs. I have read that this is happening to others and Honda really needs to address this issue.

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 federal safety agency review this issue immediately to determine if a broader safety investigation or expanded recall is required for the 2024 Honda Prologue.

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.
