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).
I have had multiple occurrences where as I'm accelerating into a turn at normal /slow speeds the traction control activates and my vehicle almost comes to a stop almost causing an accident with the vehicles behind me. This was on dry pavement and not heavy acceleration so the traction system should not have activated.
When reversing in a dark or low light area I can't see behind the vehicle on the backup camera display. It seems like there is no night vision and the reverse lights don't illuminate behind the vehicle enough to see in the display or the rearview mirror. I've almost backed into objects because you cannot see behind the vehcle.

I have had multiple incidents where I'm driving and the instrument cluster goes black and either takes multiple minutes to come back on or I have to turn the vehicle off and back on to get it to work.
Vehicle, in one-pedal-drive, began to enter an intersection from a stop sign into a left turn--mild reasonable torque applied onto a 25mph street. Vehicle entered intersection and began stuttering/slow/shaking until near/complete stop and loss of acceleration in middle of busy intersection. Traction control light illuminated briefly prior to resumption of acceleration. Road conditions were dry, slightly foggy. There was no reason for safety systems/ABS/Traction control etc. to over react. Honda dealership reported no relevant code to explain incident--which indicates vehicle also did not flag it as an aberration. Vehicle had just been at dealership day prior and received software update and reported inspection. Honda dealership will not take further action unless reproducible with error codes to tell them how to address. Specific component, electrical, or software failure reportedly unknown and remains unaddressed by Honda at this time.
The vehicle has twice displayed a -??Service High Voltage System-?? warning followed by -??Reduced Acceleration -?" Drive With Care.-?? When this occurs, the vehicle enters a reduced-power (turtle) mode that severely limits acceleration. Cabin heat also stopped working, and the vehicle would not charge beyond approximately 25%, restricting driving range. OnStar diagnostics reported a critical error. The vehicle and diagnostic history are available for inspection upon request. The first incident occurred while driving around town. Although I was close to home, the reduced acceleration created concern because the vehicle could not respond normally to traffic. The second incident was significantly more dangerous and occurred in heavy traffic and on the freeway about 40 miles from home during heavy rain. The limited acceleration made merging and maintaining a safe traffic speed difficult, placing myself and others at risk. I have only been able to get the dealer to take the vehicle in one time, specifically for this issue, and that was because the warning lights were still on at arrival. Staff observed the warnings at check-in, but by the time the vehicle reached the service area, the lights had cleared. The dealer stated they could not perform repairs without active warnings, though stored codes reportedly indicated a low-voltage condition. Additionally, a clicking noise from the wheel area began about 1,500 miles ago and occurs consistently when turning, similar to a CV axle concern. During a separate visit, the dealer put in writing that they could not do anything about the noise and did not diagnose or inspect it, which left me uneasy about potential drivetrain safety. The intermittent high-voltage fault, reduced acceleration, charging limitation, loss of heat, and unresolved drivetrain noise create ongoing safety concerns due to the unpredictable nature of the failures.
The contact owns a 2025 Honda Prologue. The contact stated that while parked and attempting to charge the vehicle, the vehicle failed to charge. The battery warning light was illuminated, and the message "Service Critical High-Voltage Battery" was displayed with a flashing red battery in the corner. The vehicle was towed to a dealer and was diagnosed with a critical battery failure. The vehicle was not repaired; however, the battery was reset, and the vehicle was drivable. The failure had occurred approximately five times. On another occasion, while driving at an undisclosed speed, an unknown warning light illuminated, and the message "Adaptive Cruise Control Unavailable" was displayed. The vehicle was taken to a dealer, but it was not yet diagnosed. The manufacturer was not notified of the failure. The failure mileage was approximately 8,000.
First of all, my Honda app took me a month to get into and sign in due to app issues which are very annoying and when I drive my car and turn the wheel, it makes axel sounds my screen shut off on me. One time I got a high voltage system warning the battery drains out quick. The door hits the other door every time you open driver side
Unknown electrical issue in the cold. Saw posts online about people getting "High voltage system" errors and after a few days in the cold it happened to me. Dealership couldn't find the issue and simply cleared the error codes telling me to come back in if it happens again. Huge issue, as it limits the range to protect the system from further issues but doesn't give me enough range to even drive home from work if the errors appears during my commute. Occasionally my front sensors don't work but give no indication of any issues, other times it notifies me that they need cleaned, but not always. Not reliable enough to trust in anything but perfect circumstances. I am also getting the CV joint clicking issue occasionally when turning, unsure if related to cold weather or not but it has only happened in 10-20 degree weather. Sounds very bad when it occurs, not very reassuring when driving a car with less than 6000 miles on it.
The contact owns a 2025 Honda Prologue. The contact stated that while driving at various speeds, the battery suddenly experienced a loss of power. An unknown message was displayed. The vehicle was taken to a local dealer, where it was diagnosed; however, the cause of the failure was not identified. The vehicle was not repaired. In addition, the contact stated that the failure had progressed over time. The manufacturer was made aware of the failure. The failure mileage was approximately 1,000.
I received another service high voltage system message literally weeks after I brought my vehicle in and had the issue fixed. I reported this issue last on 11/24/2025 it is now 12/19/2025 and it happened again. The heat in my vehicle seemed to stop working and was blowing cold air. This is just poor design and disgraceful.
My vehicle recently began displaying the error messages -??Service High-Voltage System-?? and -??Reduced Acceleration -?" Drive With Care.-?? Since these warnings appeared, my vehicle-??s heating system no longer works at all. This defect creates multiple serious safety hazards: 1.No heat in cold weather: Temperatures in my area are currently around 42?F, and the cabin cannot warm up. This creates an unsafe temperature environment for myself and especially for my children while driving. 2.No ability to defrost windows: Without heat, the vehicle cannot defog or defrost the windshield or windows. This severely impacts visibility and creates a dangerous driving condition. 3.Reduced acceleration: The vehicle warns of reduced performance, which may affect my ability to safely merge, change lanes, or respond to traffic conditions. These issues began without warning, and the loss of heating combined with high-voltage system errors makes me concerned about a potential electrical or battery system failure. This is a significant safety concern that needs to be investigated, as the vehicle is not safe to operate in its current state. I request that NHTSA look into this issue, as other owners have reported experiencing this same dangerous combination of high-voltage errors and loss of essential climate-control functions with no resolution from the manufacturer.
Vehicle makes click-click-click (2-4) on hard over turns with accelerations (e.g. parking lot exit to street) Sounds front right CV/Axle region. Vehicle has intermittent MIL "Service High Voltage Soon" which resolves on subsequent startup, might be linked to scheduled charging within car infotainment.
Brake by it self on the street multiple times and then when I-??m goin reverse it sence sometimes something and does not let me go also the battery does not let me charge more of 20% when the red car on the dash apear and it has a noise when your turning
My 2025 Honda Prologue Elite is experiencing multiple safety-related issues. The front CV axles make a consistent clicking noise when turning, indicating a possible drivetrain or axle defect. The power tailgate also intermittently and unexpectedly closes on its own while loading or unloading, creating a risk of head injury. In addition, the infotainment screen and digital gauge cluster will randomly shut off while driving-?"sometimes for up to 30 seconds-?"leaving me without speed, range, or other essential telemetry while the vehicle is in motion. All of which the dealer will not address or states they can't replicate.
While driving I received a warning that said -?? service high voltage system-?? that came up on my dashboard. I have had my vehicle just for a couple of months and this is the second issue that I am having with the vehicle since purchasing it. I have taken it back to Honda who is now telling me that they have to do some tests to try and figure out the issue which seems to be a know issue which some forums show that may effect the heating system or cause you to need a complete battery replacement. I have my vehicle in service now waiting to see what the issue is but but for a brand new vehicle there has to be an even bigger problem if the issue is happening not only on my vehicle but on its sister vehicles as well the made by Chevy.
The front center counsel which contains the USB and 12 volt charging ports comes off the car-??s body and exposes the wires. This can lead to people getting electrocuted and hazardous for kids.
