2025 Honda Prologue Problems: 6 Known Issues

On the 2024-2026 Honda Prologue, prologue owners report the low-voltage 12V auxiliary battery going flat far short of its normal 4-6 year service life, in some cases on nearly new vehicles and after only overnight or a week of parking with a healthy high-voltage pack state of charge. Because every system in the car is electronically gated by the 12V rail, the failure does not look like a slow crank - it produces a dead or flickering display, a shifter that will not move out of Park, a car that will not power up at all, and 'Service Battery Fault - Shutting Down Soon' messages. A weak 12V also prevents the high-voltage contactors from closing reliably, so AC and DC charging sessions abort with relay clicking and never start, which owners frequently misdiagnose as a charger or charge-port problem. Root causes reported at dealers include a genuinely defective cell in the original battery and parasitic drain from modules that fail to sleep.

On the 2024-2026 Honda Prologue, a recurring Prologue-specific complaint is the charge port door itself. The door will not latch closed and pops back open, or the latch position sensor fails to register a closed door so the vehicle displays a persistent 'Charging Door Open' message even with the door visibly shut. Because the vehicle uses charge-door state in its charging and drive-away logic, owners also report the car refusing to initiate a charge session or nagging continuously while driving. Some owners report the charge cable latching mechanism not releasing cleanly. Lubricating the locking mechanism has not resolved it in the reported cases; dealers have resolved several by replacing the complete charge port door assembly, and in some high-voltage-fault cases the charge port assembly itself was replaced.

On the 2024-2025 Honda Prologue, honda recalled 2024-2025 Prologue (44,199 units, alongside the 2024 Acura ZDX, ~59,887 total) because the rearview camera housing was assembled with improperly bonded seams. Moisture penetrates the camera body, corrodes the internal electrical components, and the center display eventually shows a blank or badly distorted image when the vehicle is shifted into reverse. This is a HARDWARE defect distinct from the earlier Radio Control Module software recall (26V112) that blanked the whole instrument panel - it cannot be fixed by an OTA update. Honda estimated roughly 4% of the recalled population actually exhibits the defect but recalled the full build range. Improved cameras entered production June 9, 2025, so later builds are outside the population.

On the 2024-2026 Honda Prologue, the 2024-2026 Honda Prologue has a widespread defect causing loud clicking or knocking sounds from the front axle area, especially when making turns or accelerating from a stop. CarComplaints lists more than 180 NHTSA suspension complaints for the 2024 Prologue, and many owners report the noise appearing within weeks of delivery. The CV joint boots or inner joint assemblies appear to be defective from the factory. Honda issued a Tech Line Summary Article on December 19, 2025, acknowledging the 'clicking or ratcheting type noise when turning' but directed dealers not to attempt repairs if no visible damage is found. Replacement axle parts have been backordered nationwide due to the volume of affected vehicles.

On the 2024-2026 Honda Prologue, prologue owners in cold climates report the heat pump climate system failing to deliver cabin heat: the heater cycles itself on and off, blows ice-cold air in sub-freezing conditions, or stops working entirely. Dealer findings in documented owner cases point at the refrigerant circuit shared with the battery thermal system - low refrigerant charge in the heat pump, failed valves, and in one case a bent purge valve requiring hose and pipe disassembly and seal replacement. Repairs have been slow, with one lessee reporting the vehicle held at the dealer for approximately four weeks waiting on valve parts. Because the heat pump refrigerant loop is shared with high-voltage battery conditioning, a leak here can present as an HVAC complaint, a charging complaint, or both at once - owners have reported low refrigerant in the heat pump also affecting the charging system.

On the 2024-2026 Honda Prologue, separate from the recall that blanks the screens entirely, the Prologue's Radio Control Module produces a family of persistent connectivity and stability faults. Owners report wireless Apple CarPlay and Android Auto dropping out repeatedly - notably over rough pavement, which points at a connector or antenna seating issue rather than a phone problem - phones that will not pair or that vanish from the pairing list, the center display freezing when switching to the SiriusXM source, CarPlay disappearing from the menu entirely, and the wireless phone charging pad failing to charge or causing the system to stop recognizing a phone if the phone is placed on the pad before the vehicle is powered on. Honda has addressed portions of this in software: TSB 25-051 (A11 Radio Control Module Software Updates #1, July 30, 2025) specifically fixes the SiriusXM source-switch freeze along with volume and chime tuning and a missing 'BRAKE' message during front collision warning, and TSB 25-081 covers vehicle-wide programming.
