Electrical issue

I owned jaecoo J8 hybrid since October 2025 and i found that it has several issue with the car itself. I experienced several number of malfunctions and that is:1. The whole car shut down and cannot be started at all so a mechanic has to be called and perform battery jumper. The car is brand new at that point and jaecoo mechanic cannot establish the error when it was scanned using their computer the battery voltage is normal2. Air conditioner shuts down in the road whilst driving, the car display shows mil engine and the temperature sensor isn’t reading. After performing shut down and restart it still the same error so i have to visit jaecoo dealership to get this issue fixSo this is the two main issue i faced recently i hope jaecoo pays attention with the production so people don’t experience the same thing i had.

A charger expert told me about an issue with electric vehicles from several brands, such as Porsche. Normally, the high-voltage battery periodically checks the 12V battery and charges it if it's low. However, this function gets disabled when you plug the car into the charger. When you connect the charger, the 12V battery is used to activate the charging systems. If you keep it plugged in without charging for many hours, the 12V battery could run out of power. That's why, when charging is scheduled for several hours later, it is best to program the charge in the car, not on the charger
