What is the problem that the old Haval H6 suddenly stops refueling when driving normally?

Generally speaking, it is not the fault of the vehicle itself that it can't be refueled during driving.

Because most people think this kind of suspected fault, in fact, a project is not maintained.

Please check the maintenance manual, focusing on the replacement/cleaning time of transmission oil, spark plug, throttle and other parts.

See if there are any omissions during maintenance.

If so, please complete these maintenance as soon as possible.

By the way, if the car runs a long distance, it needs to clean up the carbon deposit.
