High voltage system errors. Won’t charge. Car is 2 weeks old!
While driving in traffic, the car unexpectedly applied the brakes and displayed a 'Service High Voltage System' warning on the dashboard. Shortly after, another message appeared: 'Service Vehicle Soon,' followed by 'Reduced Acceleration - Drive with Care.' The car isn't charging and lacks the speed needed to drive on the highway.
Twice the prologue warnings have come on that state “service high voltage system" and "reduced acceleration. There is no AC/HEAT in the vehicle under 35 degrees. Under 6000 miles
Received multiple alerts including "service high voltage system", "service vehicle soon", and "cannot charge". The vehicle also reduced speed and function, which could have resulted in reduced driver safety. Vehicle will be brought in for service to determine cause.
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.
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 contact owned a 2024 Honda Prologue. The contact stated that while stopped at an intersection and attempting to make a right turn, the steering wheel was frozen and the vehicle began to independently accelerate at an unknown speed. The contact stated that he was depressing the brake pedal but the vehicle was not stopping. The contact stated that he crashed into a vehicle in front of his vehicle on the other vehicle's passenger side front door. The air bag deployed. The contact stated he was not aware of any warning lights. The contact stated that the police and emergency service vehicles arrived. The contact was not injured and did not receive any medical attention. The police filed an incident report. The vehicle was towed from the scene to an impound lot and later was declared a total loss by the contact's insurance provider. The manufacturer was informed of the failure. The failure mileage was approximately 2,000.
