It is normal for the fuel nozzle to occasionally click off when refueling a new car. Reasons for the nozzle clicking off during refueling: This may be due to blockages or poor fuel flow in the fuel line. Additionally, it's important to check the ventilation condition of the air vent near the fuel filler neck. If the vent pipe is blocked or deformed, causing poor air circulation, it can easily lead to the nozzle clicking off. Refueling precautions: Try not to wait until the fuel warning light comes on before refueling. The fuel pump is located inside the fuel tank and operates at high temperatures during continuous use. Being submerged in fuel helps to effectively cool it down. When the fuel light comes on, it indicates that the fuel level has dropped below the pump. Consistently waiting until the light comes on to refuel can shorten the fuel pump's lifespan. Having too little fuel or running out of fuel completely may even cause the fuel pump to burn out.
My new car occasionally experiences pump shut-off during refueling, which gave me quite a scare as I thought there was some major issue. Later, after consulting friends and mechanics, I learned that in most cases this is normal. New car fuel tanks have excellent sealing, and the refueling process generates vapor pressure. When the pump detects this, it automatically stops to prevent overflow—this is called the vapor lock effect. It's especially common during rapid refueling or in hot weather, and nothing to worry about. I recommend slowing down the refueling speed next time, not inserting the pump nozzle too deep, and waiting a few seconds before restarting. If the pump shuts off frequently, then you should check whether the fuel cap is loose or the vent hole is clogged. During maintenance, when I mentioned this, the technician said repairs are usually unnecessary, but regular inspections of the fuel tank system can prevent minor issues from turning into major repairs. Overall, occasional shut-off protects the vehicle, so don’t panic and drive nervously because of it.
