2024 Honda Prologue

I’ve had a couple of issues with this vehicle along with others I know with the same car. 1. When charging it has said a couple of times “not sending power” when public charger seems to be in good condition & there being funds on the card. 2. When closing the panoramic sunroof right when it’s about to close it opens back up. It takes me multiple tries pressing and holding down the button to get it to close. 3. Both screen displays have gone completely black out of nowhere and will not turn back on until a couple of hours later. 4. Sometimes in perfect Sunny condition with nothing blocking the windshield the Forward collision Safety feature will appear on the dashboard saying “forward collision system unavailable.” 5. The battery seems to not last long and even going at speed limit or slower the battery will still drain fast.

Component/System Failure: The high-voltage battery system in my 2024 Honda Prologue failed. According to the Honda service center, the battery needs to be replaced. The vehicle is currently at the dealership, not ETA when the part will arrive or when will I get my car back. Safety Risks: The failure prevented the vehicle from charging, which could have left me stranded. Additionally, the system displayed multiple warnings, and since this is an EV, a malfunctioning high-voltage battery poses a potential fire or electrical hazard. The car was not drivable due to the severity of the issue. Problem Confirmation: The issue has been confirmed by the Honda dealership, which diagnosed the high-voltage battery as the cause of failure. They recommended a full battery replacement. Inspection by Others: The vehicle has only been inspected by Honda service technicians at my local dealership. It has not been reviewed by the manufacturer directly, law enforcement, or an insurance representative. Warnings and Symptoms: The failure first occurred two days ago when I attempted to charge the vehicle at home, but it would not charge. Multiple warning messages appeared on the dashboard, including: "Service High Voltage System" "Service Engine Soon" A red car icon with an exclamation mark I attempted multiple times to charge, but the vehicle continued displaying the same warnings. The next day, I brought it to the Honda dealership, where they confirmed the high-voltage battery issue.

On February 25, 2025 my car decided to throw the code that said service high voltage system. I was on my way to drive my son to school. I have been driving for about two minutes and then the code showed up I called my dealership at 10 AM that morning and told them what was going on. They told me to come down there and they will take a look at the car. I bought this car on February 14, 2025. It has 370 miles on it at the time when I got to the dealership the first person turned me back and said that they couldn’t do anything because on the way to the dealership, the code went away. I left the dealership went to charge my car. It charged for 3% at the public charger and then it shut off. I went back to the dealership and this time they kept my car because the code was on when I arrived and the other guy apparently made a mistake and sent me home when he wasn’t supposed to. I got a loaner. I finally got my car back on March 8, 2025. I drove it a little bit yesterday and then I drove it a little bit more today which is march 9, 2025 my day was winding down so I figured I would go to target and get what I needed and charge my car while I was there. I went to the public charger. The car charge for about three or 4% and then it shut off I got the alert on my phone so now I must go back to the dealership when they open because today is Sunday and take my car back there. The code is now back on the car. apparently, while at the dealership, they couldn’t see anything while they had the car the code wasn’t showing up and then the dealership said that they had the Honda engineers look at the car and talk to him about it, and they couldn’t find anything wrong and they told me to bring it back in if it happens so I guess that’s what I’ll do currently the car has about 430 miles on it. I got it back and it had 390 something miles on it.

“Charge Door Open” warning appears on dashboard when the charge door is completely closed. This warning appears incessantly while driving. Additionally, “Service High Voltage Charging System” appears along with the “Charge Door Open” warning. The problem is documented on video at 780 miles on the odometer. These warnings occurred at low speed driving between 30 and 35 mph.
