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 ds 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.
