The cause of noise from the car seat belt buckle is its friction or contact with the passenger seat. It could also be due to the belt slipping on the pulley, which results in noise. Another possibility is that the seat belt's fixing screws are loose. If it's a new car still under warranty, you can simply have the 4S dealership handle it during maintenance, or you can address it yourself. More relevant information is as follows: Solution: Prevent the seat belt buckle from contacting the seat. The passenger seat belt buckle may have too tight shock absorption, or the screws under the passenger seat may not be tightened or secured properly. It might not be the seat that's loose but the base underneath, which can be tightened. Note: Since the pin and the holes in the bracket and base are pin-connected, there is a certain amount of play. Therefore, when the vehicle is driven on cobblestone roads, the shaking can cause the pin to hit and produce noise. Additionally, there may be a gap between the flat washer at the pin and the limit base, causing noise from the washer hitting the base while driving. If the internal limit rod of the recliner has excessive looseness or the recliner's fixing bolts are loose, applying lubricating oil can help.

There is strong magnetic field interference around the car; 2. The car has malfunctioned; 3. The battery is dead or has poor contact; 4. The antenna of the remote transmitter in the car is aging; 5. The time control module in the remote key is faulty. The solutions for when the car key does not respond when locking the car are: 1. Check the battery circuit or replace the battery; 2. Check for aging circuits; 3. If the remote key does not work, use the mechanical key to lock the car; 4. Check the lock block and the condition of open or short circuits in the control circuit; 5.

What is the gap size of a car spark plug?

The normal gap of a spark plug is generally 0.6~1.3 millimeters. Spark plug replacement procedure: Open the hood, lift the plastic cover of the engine, remove the high-voltage distributor wires, and mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for external debris like leaves or dust and ensure thorough cleaning. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the removed high-voltage distributor wires in the firing order, then secure the cover. Spark plug replacement interval: Under normal maintenance conditions, replace spark plugs every 40,000~60,000 kilometers. However, this may vary depending on the brand and engine type, so it's recommended to follow the owner's manual. Platinum spark plugs should be replaced at 40,000 km, standard nickel alloy spark plugs at 20,000 km, and iridium spark plugs at 60,000-80,000 km.

What to Do If the Vehicle Stalls Suddenly While Driving?

If the car stalls suddenly while driving, depending on the road conditions at that time and if there is no emergency, you can slowly apply the brakes to prevent a rear-end collision. After the speed decreases, steer slowly to move the car to the roadside lane. Once parked at the roadside, turn on the hazard lights, set up the warning triangle, and call for a tow truck. Common causes of stalling are as follows: 1. Stalling due to carbon deposits: Especially at the electronic throttle, this is an intake system fault. When there is excessive carbon buildup at the throttle, releasing the accelerator while driving may cause the engine to stall, which often occurs in very old cars. However, this can be prevented. Normally, you may notice difficulty starting the engine, or even needing to press the accelerator to start it—these are signs of excessive carbon deposits at the throttle, which require timely cleaning. 2. Fuel supply failure: Usually caused by a damaged fuel pump, which cannot pump fuel. The fuel pump has a long lifespan, so damage typically occurs in older cars. Some fuel pumps fail while the car is parked, making it impossible to start, while others fail during driving. 3. Power supply failure: Usually caused by a damaged ignition coil, resulting in no high-voltage electricity to all spark plugs.

Does Installing a Spoiler Increase Drag?

Installing a spoiler does increase the drag of a car. A car spoiler refers to the protrusion installed along the upper edge of the rear end of the car's trunk lid, and it is one of the components of aerodynamics. The primary purpose of installing a spoiler is to increase the downforce at the rear of the car, thereby reducing drag during driving to enhance the car's stability. This technology was initially used in racing cars. However, installing a spoiler on a car is considered illegal modification and is a violation of the law. The penalties and relevant regulations for illegal modifications are as follows: Penalties for Illegal Modification: Driving an illegally modified car on the road will result in the vehicle being impounded by the traffic management department of the public security authority, the illegal device being confiscated, and the owner being ordered to restore the vehicle to its original condition, along with a fine imposed according to the law. Relevant Regulations: For illegally modified cars, the traffic management department of the public security authority will not issue a safety technical inspection compliance mark. If the modification constitutes a violation of public security management, the public security authority will impose penalties such as fines or detention in accordance with the relevant provisions of the "Public Security Administration Punishment Law." When modifying your car, it is essential to apply for a modification registration with the traffic management department of the public security authority to ensure that the modified car can pass annual inspections and routine safety checks.
