Additionally, the accelerator pedal was depressed, but the vehicle went into neutral. While driving 60-65 MPH, the vehicle went to 70 percent charge. There was an abnormal clicking sound coming from the axle and CV joint. While using the turn signal, the turn signal responded on the opposite side as intended and turned on the windshield wipers. The contact was unable to locate the hazard lights. The contact called OnStar, who contacted Honda for a jumpstart. Another tow company was contacted, who was unable to tow the vehicle due to the vehicle not shifting into neutral. …

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. …
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. …
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. …
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. …
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. …
