2024 Honda Prologue electrical system problems

“I purchased my 2024 Honda Prologue on [XXX]. On [XXX], I opened a case with American Honda because the vehicle has an open rearview camera safety recall, NHTSA Recall 26V-306 / Honda Recall D05. Since then, I have repeatedly contacted American Honda and several authorized Honda dealerships trying to get the recall repaired. I have spent weeks calling representatives, speaking with case managers, contacting dealerships myself, and trying to understand who is responsible for providing the replacement camera. I have received conflicting information and very little clear assistance. On [XXX], Future Honda in Citrus Heights inspected the vehicle. Their repair order states: “SAFETY RECALL CAMPAIGN: REAR VIEW CAMERA - REPLACE.” The rearview camera was not functioning at the time, and the dealership told me the replacement camera had to be requested or ordered through Honda. Future Honda later told me the request had been submitted and they were waiting for the part. On [XXX], an American Honda representative left me a voicemail stating she had contacted the dealer, confirmed the part was ordered, and that I needed to continue waiting for it to arrive. As of October…”

“My 2024 Honda Prologue Touring AWD has repeatedly displayed a “Service High Voltage System” warning. During a recent repair, Heritage Honda of Westminster explained that an A/C refrigerant leak reduced the system’s ability to cool the high-voltage battery and caused the vehicle to enter protection mode. The dealership replaced leaking A/C seals and recharged the refrigerant. After charging the battery, the check-engine light came on. The dealership contacted Honda Technical Support and installed a software update. I picked up the vehicle on XXX, after these repairs. That same night, the “Service High Voltage System” warning returned. I have a photograph documenting the warning and have notified the dealership. I am concerned that the underlying problem remains unresolved and could affect battery cooling or vehicle operation while driving. I have asked the dealership whether the vehicle is safe to drive or charge. Please review this recurring warning and the related battery-cooling and protection-mode issues for a potential safety defect. Honda Corporate case number: XXX. VIN: [XXX].”

“The center display and instrument cluster on my 2024 Honda Prologue fail intermittently while driving. When the instrument cluster drops out, I lose the speedometer and driver information display. When the center display fails, the backup camera image is unavailable, along with audio and climate information. On July 24th, while driving at approximately 45 mph near Keuka Park with my family in the vehicle, the center display went black. Minutes later, the instrument cluster cut out and recovered three separate times. I recorded video of the display failure and two of the cluster dropouts. The problem began at 868 miles, about three weeks after delivery in April 2025. Dealers replaced the touch screen audio unit in May 2025 and the radio control assembly and infotainment module in June 2025. The problem returned. Honda Recall 26-056 (Meter/Center Display software update) was performed on 5/5/2026, and the dealer technician documented on the repair order that the screen was still flickering and freezing immediately after the recall. A later dealer visit could not duplicate the problem. Failures continue, and I have ongoing video documentation. The recall remedy…”

“On the morning of October 6, 2026, approximately 0500 PST, the vehicle displayed a "Service High Voltage System" warning on startup and the estimated range display went blank ("-- mi"). The high-voltage battery system was not delivering power. This appears to be the same defect reported by multiple other 2024 Prologue owners (sudden HV system fault, reduced or no propulsion, loss of charging). It also states battery is low, separate from the HV message. Honda Roadside Assistance will be contacted today and I will request the vehicle be towed to the (a) dealer as the vehicle is not able to move at all nor do I feel safe to operate the vehicle as I am and would be concerned about potential loss of propulsion while driving if this fault occurs at speed.”

“I have been calling Honda of Temecula, Ca since February of this year. I have been calling them monthly to fix my recalls and their response is " I have one to and we do not have the parts and software for the vehicle." I lease this vehicle and still have until December 2027. A recall should be repaired in a timely manner and I am now going on 8 months. I would happily turn in this vehicle for another lease. I have already had the battery replaced, spend countless hours at honda, had rental cars half the size, and been inconvenienced for years now.”

“My car has a recall for a defective rareview camera (showing all black). I took it to the dealer 2 months ago and they told me that i have to wait for a camera replacement and that they do not know when the part will be available. This is a major safety issue for me and I am not sure how to expedite the process. Or what are the alternatives as I need a car but do not feel safe driving it. Thanks!”
