2024 Honda Prologue

Pulled out of our driveway and received a message that "AWD Temporarily Unavailable". This message did not indicate that this fault disables one-pedal driving. Upon reaching the end of my street at the stop sign, I gently let my foot off the accelerator expecting the car to slow down as it should when using one-pedal driving. Instead the car continued to move forward and I almost went through a stop sign into a busy road where I would have for sure gotten into a bad accident. Not informing the driver that this fault also disables one-pedal driving is extremely hazardous.

Twice, a "service high voltage" error light has come on and it has said it impacts the ADAS and safety systems and the acceleration of the vehicle. The light disappeared after a short drive, but the heating system stopped working. The first time, we took it to the dealership and they reset the system and the heat came back a little, but seems to struggle under 32 degrees, and especially sub 15/20 degrees. The second time was this morning - the heat is barely working at all. Very frustrating for a vehicle under 2000 miles.

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 was driving in the highway, at ~70mph with cruise control on when the error popped up. The temp was been 47-52°F. I got a message saying Service High Voltage System. I thought nothing of it and proceeded with rest of my trip. I went to even colder conditions and got down to 28°F at one point. I noticed that in the car, the AC was not working, it was only blowing cold air from outside. Eventually went to charge and and the car refused. I was 70 miles from home but was able to get a tow.

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.

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.

Car makes loud knocking sound when turning, especially when cold. Started almost immediately after taking delivery. Happens every time drive car and is getting worse. Available to inspect. Safety risk if drive axle snaps. Not inspected by anyone, but a known issue in owners' forums and among dealer service departments: [XXX] No warnings or codes thrown.
