2025 Honda Prologue

The contact owns a 2025 Honda Prologue. The contact stated that on several occasions while driving at undisclosed speeds and removing the foot off the accelerator pedal, the vehicle unexpectedly came to an immediate stop. The Auto Hold, service brake assist, service stability link, high voltage light, and ABS warning lights remained illuminated. The vehicle was taken to a local dealer where the vehicle was diagnosed, and the contact was informed that the dealer was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 10,000.

On June 11, 2026, my 2025 Honda Prologue displayed a High Voltage System Alert immediately after I attempted to charge the vehicle. The vehicle would not accept a charge and became inoperable. I brought it to the dealership the same day, and the vehicle has remained there since. The dealership first replaced the charging port, but the vehicle still would not charge. On June 24, 2026, the dealership informed me that the transmission lines from the charging port to the battery needed to be replaced. Since that date, I have not received any updates, repair timeline, or confirmation that the issue is being addressed. The vehicle is currently unusable and cannot be charged. The high‑voltage alert indicates a potential electrical system failure involving the charging system and high‑voltage components, which may pose a safety risk. The defect has left the vehicle inoperable for over a month with no resolution.

Drop off a few days after receiving vehicle. Picked up and dropped back off the same day due to issue repeating it self after being told there was no issue. Parts were supposedly replace on one of the occasions. No real time spent on the vehicle according to invoices. 8/28/25 -9/4/25 9/4/25 - 9/15/25 9/24/25 - 10/14/25 I have brought the car in for the same problem multiple times without it being rectified. I currently have videos and pictures from when this started to this current time. There are also other customers that have the same complaints that I do. Below is a list of issues that have been going on since first complaint including continued first complaint. I do believe that this is an issue and is a danger due to the reverse camera glitching due to the screen, not being able to get out of the screen, sometimes can not leave a parking space due to the sensor says that there is something in the way where indeed there is nothing. Also can not pull out of drive way during snow due to the car automatically breaking for snow. The collision for the front is always going off when there is no need for it to go off as this can cause someone to unexpectedly stop due to this being something that is supposed to be a warning. If this could happen to the vehicle constantly without a solution then this could be connected to something much more serious. There are other issues that have gone on as well that I have slowly started to notice and pay attention to. I do believe that the amount I am paying for this car it should not have these issues with out explanation. Clearly this is common and on going. One thing can lead to another with these issues. The screen in the middle of the dashboard —- Screen goes black for no known reason Screen flashing Screen is rainbow Touch screen will not work at these times When screen is glitching you can not turn volume down or off, disconnect phone, charging port goes out. Can not back out of parking space due to sensors going off.

While driving yesterday the service high voltage system light came on again. I have brought my vehicle to Honda 2 other times for the exact same issue. They fix whatever the issue is and the problem happens again. That last time it was about a month after bringing it to them but this time is has been 3 possibly 4 months but I have have the car less than 1 year.

This issue has occurred twice. The first time was at approximately 3,000 miles, and the second time at around 7,200 miles. On both occasions, the vehicle lost power and displayed a warning message stating “Service High Voltage System” along with a “Reduced Speed” notification. During these events, the estimated driving range dropped significantly, charging was limited to approximately 25%, and acceleration was severely restricted, indicated by a turtle icon on the dashboard. After the first occurrence, the vehicle remained undrivable for approximately three days over Thanksgiving. By the time I was able to bring it to the dealership on the next available business day, the warning light had turned off. I was advised to bring the vehicle in immediately if the issue happened again. The issue did not reoccur for about three months. When it happened again, I was out of town and the estimated range dropped from over 100 miles to around 60 miles. I was able to make it home without requiring a tow and brought the vehicle to the dealership the following day. At check-in, the service advisor observed that the warning lights were still active. However, later that day I was informed that by the time the vehicle was inspected, the warning lights had turned off, and no action could be taken. Based on information found in online owner forums, this appears to be a known issue potentially related to a defective component. It has also been suggested that the issue is more likely to occur in colder conditions. Due to the unpredictability of this failure and the loss of power and range when it occurs, I do not feel confident in the reliability of the vehicle, particularly for longer trips or travel in remote areas.

Upon start-up the driver display was off, showing no information. Center infotainment display remained on. Attempted infotainment reset by pressing and holding the hang-up call button on the steering wheel, and after approximately 30 seconds the infotainment display turned off, driver display remained off. Shutdown and started car, both screens remained off.

The camera visibility systems on this vehicle become extremely dark and largely unusable at night. This affects multiple cameras, including the rear backup camera, which is the most problematic. In low-light conditions, the display does not provide a usable image of the area around or behind the vehicle. When reversing at night, the rear camera image becomes so dark that pedestrians, obstacles, or other vehicles behind the car cannot be seen. This creates a significant safety hazard because the driver cannot rely on the camera system to safely maneuver or reverse the vehicle. All rear lights and exterior lighting on the vehicle are functioning properly, which suggests the issue is related to the camera system itself, image processing, or the vehicle’s configuration for low-light conditions rather than a lighting failure. Because the rearview camera system is intended to provide rear visibility and prevent back-over incidents, the system failing to provide a usable image at night defeats its intended safety purpose and creates a risk of a back-over crash or collision. The issue has been persistent since the vehicle was delivered and occurs consistently during nighttime operation and other low-light conditions. The rear visibility system appears unable to perform its intended safety function under normal nighttime driving conditions, raising concerns about whether the system is functioning as required under Federal Motor Vehicle Safety Standard No. 111 (Rear Visibility).
