2024 Honda Prologue engine problems

ENGINE

High voltage system error has flagged and been fixed multiple times starting in early January of 2026. Car randomly warns and breaks in the middle of the road because it sensed something that wasn’t there. Luckily no wrecks have occurred. Both CV joints have a loud clicking noise that the Honda dealerships knows about but has no fix for. I currently have an appointment for the dealership to look at my brake and high voltage system again.

starting on dec 24 and again on dec 25 the tcar has been having problems shifting into gear. THIS IS JUST ONE OF THE MANY PROBLEMS I have been having with this car I have already submitted a ticket on this car. This car needs to be recalled nation wide, OI do not feel it is safe to drive and it is only a matter of time until this model will be involved in many accidents resulting in many injuries.

Yesterday 11/30/25 we were going on the freeway about 60 mph, when suddenly I got the warning that my battery and acceleration were impacted due to a battery issue. States to service battery soon. It stayed that way as we were headed to have some blood work. That warning continued until the evening when it disappeared so thought it was a glitch. I still setup an appointment to have it checked at the dealership on Thursday 12/4/25 at 8:15am. On 12/1/25 at around 7:35am I was about to break at a light when I feel this jolt from my car and the same warning lights stayed on. I was really concerned so when I got off and went to work I immediately called the service department to move my appointment up to Tuesday 12/2/25 at 7am first thing. I dropped off the car at night for them to work on it. This seemed to impact also the Heater as it was cold air coming from my vents. I have seen this issue in Facebook and Reddit but felt I may not experience it as I had 8000+ miles on it with various long road trips. But now I am worried about the reliability and safety of this vehicle. Hope they can fix it and soon.

SEVERAL LIGHTS BEGAN FLASHING, AND THE ACCELERATION stopped at 25 mph: 1. Service High voltage 2. Service Vehicle Soon 3. Reduced Acceleration - Drive With Care I brought the car in the next day. The service center at Honda Mahwah diagnosed the problem immediately. They said it is a valve for the AC system that cools the battery. They know this valve is bad on many Honda Prolouges and needs to be replaced. They said there is a "Service Bulletin" out for this problem. Then they said they do not have this valve and have no idea when it will be available. They did not want my car to sit on their lot, nor did they offer a loaner. I have not driven the car since, and it sits in my driveway, not the garage. I'm afraid of the high voltage problem, and I do not want the battery to explode in my garage. I think the NHTSA should issue a recall so this can be fixed. Pictures attached.

The EV battery would not charge. There were 2 messages, but nothing to indicate the issue, except that it was unable to charge. Took it into a dealer for service who stated that the freon was low. Without freon, the battery won't charge due to possible overheating. This was a brand new car - owned 2 days. They refilled the freon and charged the car. They could not find any leaks.

The car had an error with a front safety camera, the car stopped in the middle of an intersection and I had to coast into the nearest parking lot. The error cleared it self but Honda was of no help. The dealers do not know how to fix the cars.
