2024 Honda Prologue

I was driving on the freeway when a few error lights came on—the Reduced Acceleration, Propulsion System Icon, and a turtle icon on the dashboard and I had to floor the accelerator pedal to maintain my speed. I then pulled over, and the vehicle wouldn’t shift into drive or reverse. It gave an error message saying “conditions not meet.” Eventually, the car started working again. This is an ongoing issue with the car and Honda doesn’t want to do a buyback, this car is a lemon. I keep taking it to the dealer and all they do is clear the codes and state they can’t “duplicate” any of my concerns.

I purchased Honda Prologue Elite Model in May 2024. In around December, a warning sign "Service High Voltage System" message showed up. We left the EV for service twice since then and the first time the honda dealer mentioned that the A/C and Battery Sensors were in swapped positions and they fixed the issue by swapping positions and was set right. The warning came back again around two weeks later and the 2nd time around, they said the DTC P0534 A/C Charge was low and that this error must have happened at assembly. The warning disappeared for less than 2 weeks and reappeared again the 3rd time. Its about 4 weeks now since we have left it for service and when we called them couple of times, they mentioned they are waiting for the parts from Honda and dont have an ETA. Its 4 weeks and we do not have the vehicle after investing 60K. We made several calls and emails to American Honda Motor Co., Inc asking for update on the Issue and the inconvenience we are facing without having the car and the response is to wait until they can fix it. This is not expected from Honda whom we trusted and bought such an expensive car. It seems like they don'w know what the real issue is and each time we get some random response as a fix and the issue comes back. What's more concerning is that its an issue with the Electrical High Voltage system and we don't feel safe driving in it. I would have not chosen to by this EV if i knew they had these issues and not tested well enough before releasing for public. I have lost faith in Honda and 60K isn't small money Hoping the concerned office will Look into these reported issues and address this soon. Best

Twice in the total 750 mileage on the Prologue, warnings have come on that state “Service High Voltage System" and "Reduced Acceleration Drive with Care.” This occurred on 01/03/2025 at ~300 miles and again on 02/02/2025 ~750 miles. This error seems to be widespread with low-mileage Prologues, but Honda does not appear to be recalling to correct.

I purchased the vehicle on January 27, 2025. The morning of Jan 29th, I had three error messages pop up. 1- Service High Voltage System 2- Service Vehicle Soon 3- Reduced Acceleration Drive With Cate The vehicle would not allow me to connect via Bluetooth. My phone was no longer paired. I took immediately to the service dept at the dealership where I purchased the vehicle. Was told it was an issue with the AC, an A/C pressure valve would need to be ordered. 7-10 days for part to come in. Vehicle is in service dept waiting to be repaired. Only 79 miles on the odometer.

show a "Service High Voltage System" message. The Honda Prologue we purchased in May 2024. We have left it with the dealership for the 3rd time now and problem kept coming back. As a first time EV user we are concerned of safety and ofcourse not knowing what is happening. The 2nd time around, I was told the DTC P0534 A/C Charge was low. This condition was not detected the first time this alert showed up. I was told that the A/C and Battery Sensors were in swapped position (ie wrongly swapped positions) and that this error must have happened at assembly. I have dropped off my EV at Dealership on Jan-9th and today is 31st and still haven't got any updates on it and i am without my car. No one seems to know what the issue is really and randomly suggest somethings and problem comes back again.

Propulsion System Failure light came on and vehicle lost all cabin heat. This occurred in winter (January) and since there is no heat all vehicle windows fog over, obscuring the view of the road and other drivers. All vehicle occupants are also at risk of exposure due to complete lack of heating in sub-freezing January temperatures.

I purchased a Honda Prologue from my local dealer with just 8 miles on it. At 97 miles, multiple warning lights appeared, including "Service High Voltage System" and "Service Vehicle Soon." Additionally, the vehicle would not allow me to charge the battery once these warnings were displayed and acceleration was reduced. I took it to the dealer, where they diagnosed an overcharged AC system causing battery cooling issues. They removed 1.270 kg from the system, cleared the codes, and tested to ensure proper levels before returning the vehicle to me. After driving for another week, the same warning lights reappeared, and now, with only 360 miles on it, the vehicle is back at the dealer for further diagnosis for the same warning lights. It does not appear an overcharged AC system was the cause. For a brand-new car with less than 500 miles, this is completely unacceptable from Honda.
