2024 Honda Prologue

Unable to charge the vehicle or heat the cabin of the car when running. When turning the heat up a burning odor was observed. Dashboard warning messages state “service high voltage system”, “service vehicle soon”, and reduced acceleration, drive with care. The dealership has been in contact with the manufacturer to try and address the issue but recommended parts are on back order with no ETA. Vehicle was purchased new with 127 miles on odometer and problem occurred at about 700 miles, 3 weeks after taking possession of the vehicle.

Within two weeks of purchase from dealer, the car began having warning lights “service high voltage system”,“acceleration reduced”, “service vehicle soon”. Additionally this electric car would not allow me to charge the battery once these warning lights were displayed. Car has been towed to dealer for repair. Several attempts have been made to get update on repair time and my inquiries have not been responded to. I’m now stuck paying for a car that is less than two weeks old with less than 1,000 miles on it. All I have been told is that a call was made to the OEM based on the error codes that were read by the dealers system on intake. They aren’t telling me anything in terms of what the issue is, what the OEM fix is or a time of repair. The US govt NEEDS to be investigating Honda for consumer fraud related to this vehicle as I’ve now learned that I’m not alone and there are now numerous online forums describing the same situation I’m in presently. It’s immoral to sell a $60,000 car with a known fault and not disclose these faults prior to purchase. I would have never purchased this car had I known ahead of time that there were significant known issues that could render the vehicle inoperable within weeks of purchase.

I got the high voltage battery warning error on my dashboard after one random night of charging. The error doesn’t go away after 3 days and at times, the vehicle could not charge. I contacted my salesman and he suggested a hard reset which involved turning off the car and keeping the car fobs at least 20ft away, which worked. However I’m still concerned there is an issue with the battery. The memory seat setting doesn’t connect to the profiles. It randomly picks between 1 and 2 whenever the car turns on. Guest profiles can’t have their name saved unless their Google account is connected. The speaker rattles when volume is higher than 20%. There’s a knocking/clicking sound whenever I steer left or right. I called the dealership on 1/22/25 but was told it is not an issue. The vehicle has about 800mi on it. Front and rear collision warning sensors are too sensitive. The default settings for both are “alert and brake” which had led to random braking when backing out of a parking spot AND random braking when I was driving on the road. Luckily no accidents occurred and I have turned both to alerts only.

All car screens stopped working while I was driving. Nothing seemed to precipitate their going blank; however, because the car depends on those screens for basic information (speed, for example, turning on lights, setting one-pedal driving, etc.), the car lost some basic functionality when the screens went blank. I couldn't see how fast I was going. Luckily, because it was night and the lights had been out, they didn't go out. However, I was unable to change any of the basic features of the car that depend on these screens for access. We have a video of the screens when they went blank that we can share; however, were were unable to upload the video on this website. Upon arriving home with the car, we tried shutting off and restarting the car. It took about an hour for the screens to turn back on. We are not sure why they suddenly came on, but while they were out, the car was also unable to charge. We have brought it to be serviced, but the car dealership can find nothing wrong. We worry it could happen again. There were no warning lamps, messages, etc. before the screens went blank. The car dealership could not reproduce the problem.

The Propulsion System Error warning light (a red car icon with an exclamation point) has appeared multiple times since I purchased the vehicle. This has occurred while driving, charging, or turning on the vehicle, with no apparent cause or trigger that I can identify. I have made several attempts to have the issue resolved by Honda, but they repeatedly provide excuses, such as the unavailability of an EV technician or the lack of proper equipment to update the car's computer software. During the most recent occurrence, I was driving when the error light came on, and I experienced reduced acceleration—something I don’t recall happening before. This presents a significant safety concern for me and others on the road. A sudden reduction in speed increases the risk of being rear-ended by an inattentive driver, or worse, becoming stranded in the middle of a travel lane. Honda has inspected the vehicle previously and documented the error codes and they have just cleared the codes or updated the software on the car. No additional symptoms were present leading up to the issue. This ongoing problem needs urgent attention to ensure the safety and reliability of the vehicle.

All of sudden these 3 errors started showing on the car dashboard: 1. Service High Voltage System 2. Reduced Acceleration Drive with Care 3. Service Vehicle Soon When try to charge the vehicle, car was unable to charge with this error on the dashboard "Unable to Charge, Service charging station". Currently car is in Honda Service station since Jan 13th 2025. I received an update from the service coordinator that car is having an issue with the AC system and Honda is aware of this issue but there is no ETA on/or how to fix it.
