Not performing the second maintenance at a 4S shop does not void the warranty. As long as the maintenance is carried out according to the manufacturer's regulations, the warranty remains valid. During the three-guarantee period, any quality issues can still enjoy the three-guarantee services. Car owners are free to choose repair locations, but they must retain maintenance invoices, repair records, and certificates of conformity for replaced parts. Vehicle maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain components of the car. It mainly includes the maintenance of the engine system, transmission system, air conditioning system, etc., aiming to keep the car clean, maintain normal technical conditions, eliminate potential hazards, prevent failures, slow down the deterioration process, and extend the service life.

I've seen many cases online where skipping the second maintenance at a 4S dealership doesn't necessarily void the warranty. According to China's automotive three-guarantee regulations, car owners have the right to choose maintenance locations. As long as you go to a qualified repair shop, use qualified parts and engine oil, and keep proper maintenance records, it won't affect the warranty. Like last time when I had maintenance at my friend's shop, my car had a minor issue, and the 4S dealership still fixed it for free because I had complete invoices and records. I suggest everyone pay more attention to contract terms when buying a car or confirm directly with the manufacturer. This way, you can save hundreds on maintenance fees while avoiding being misled by 4S dealerships. The key point is that warranty remains valid when non-official maintenance hasn't caused the failure.

What does energy recovery in new energy vehicles mean?

Energy recovery in new energy vehicles is essentially the "engine braking" of these vehicles, which helps to decelerate the car during coasting and braking. The principle of energy recovery: The device for energy recovery is actually an electric motor. In middle and high school, we learned the principle of electric motors: a current-carrying conductor in a magnetic field experiences an Ampere force. The stator outside the motor generates a magnetic field, and when the rotor, composed of closed coils, is energized, an Ampere force is produced, causing the rotor to rotate. Electromagnetic induction law: Conversely, if the closed-coil rotor is rotated by an external force, it cuts through the magnetic field lines generated by the stator, inducing an electric current within the rotor coils. This phenomenon, discovered by Faraday, is known as the law of electromagnetic induction.

Do small car tires have steel wires?

Small car tires do have steel wires. Tire composition: Tires are mainly divided into several parts including the inner liner, carcass ply, steel belt, belt layer, and tread. Although tires are made of rubber, to increase the vehicle's load capacity, during the tire manufacturing process of calendaring, steel wires are pressed into the rubber to form a steel belt layer with fine steel wires embedded within the rubber. Passenger car tires all contain this steel belt layer. Material of tire steel wires: Nowadays, radial tires for cars generally have steel cord as the skeleton material of the tire. Steel cord radial tires feature long lifespan, high-speed capability, puncture resistance, good elasticity, safety and comfort, and fuel efficiency. However, if the steel wires are exposed, it indicates tire damage, and it is recommended to inspect and replace the tire.
