Does polishing and waxing a new car cause damage?

Polishing and waxing a new car does not cause damage, but it may not be necessary for a brand-new car for the following reasons: 1. New cars already come with a protective wax layer from the factory. 2. Repeated polishing and waxing can be a waste of money. The purposes of car polishing and waxing are: 1. Polishing: Polishing is a method of car paint care used to remove oxidized paint and various contaminants from the car body, eliminate fine scratches, and address minor paint damage and stains. 2. Waxing: Car wax not only provides waterproofing, resistance to high temperatures, acid rain, and UV rays but also protects the paint, keeping the car looking fresh and shiny for a long time. However, more wax is not necessarily better.

Used cars aged 2-3 years: These cars have already passed the break-in period, offering a good balance of price and condition, with relatively well-maintained performance.3.

What Does the New Car Warranty Cover?

New cars come with a three-year comprehensive warranty. The specific coverage includes the powertrain warranty, which refers to the engine and transmission, drivetrain, chassis, speedometer, and air conditioning components. If these parts encounter quality issues, they will be covered under warranty, provided that the vehicle is regularly maintained at an authorized 4S dealership according to the maintenance manual. Below is an introduction to the comprehensive warranty coverage: 1. Part Replacement: The comprehensive warranty covers free replacement of various components if they are confirmed to have quality issues rather than being damaged due to human factors, such as the speedometer or air conditioning. If these issues occur within the warranty period or the specified mileage limit, repairs will be free of charge. 2. Powertrain Warranty: The powertrain warranty covers the engine and transmission. If these components experience quality problems, they will be eligible for warranty service, provided that the vehicle is regularly maintained at an authorized 4S dealership as per the maintenance manual. It's important to note that the comprehensive warranty does not mean every part of the vehicle receives the same warranty service; rather, different components are covered separately.

What Speed is Considered Speeding?

Determining whether a vehicle is speeding depends on road conditions, such as posted speed limits, statutory speed limits, special time periods and weather-related speed limits, and highway speed limits. Posted speed limits refer to the speeds indicated by speed limit signs and markings on the road. The specific speed limit values are determined by transportation authorities based on factors such as the road's design speed, functional type, geometric alignment characteristics, traffic flow, and roadside environment. Statutory speed limits, as stipulated by the "Road Traffic Safety Law" and its implementing regulations, include a speed limit of 40 km/h on roads without a centerline, 70 km/h on roads with only one lane in the same direction, and 30 km/h when entering or exiting non-motorized lanes, passing through railway crossings, sharp curves, narrow roads, narrow bridges, or when making U-turns, turning, or descending steep slopes. The maximum speed limit on highways is 120 km/h. Special time periods and weather-related speed limits, according to the "Road Traffic Safety Law" and its implementing regulations, include a speed limit of 30 km/h on ordinary roads when driving in fog, rain, snow, dust, or hail with visibility less than 50 meters, or on icy or muddy roads. To strictly regulate passenger vehicles, speeds between 10 PM and 5 AM must not exceed 80% of the daytime speed limit. When driving normally on highways, the minimum speed must not be less than 50 km/h. The maximum speed for small passenger vehicles must not exceed 110 km/h, while large passenger vehicles, freight trucks, and motorcycles must not exceed 90 km/h. However, if there are speed limit signs or road markings that differ from these regulations, drivers must adhere to the signs or markings. Penalties for speeding: No penalty for exceeding the speed limit by less than 10%; a fine and 3 demerit points for exceeding the speed limit by 10% to less than 20%; a fine and 6 demerit points for exceeding the speed limit by 20% to less than 30%; a fine, 12 demerit points, and possible license suspension for exceeding the speed limit by 50% to less than 70%; and a fine, 12 demerit points, and possible license suspension for exceeding the speed limit by 70% or more.

What Are the Symptoms of a Faulty Charcoal Canister Solenoid Valve?

Here are the specific symptoms of a damaged charcoal canister solenoid valve: 1. Difficulty starting the engine, charcoal canister solenoid valve stuck open: Since the solenoid valve remains open all the time, the intake pipe will be filled with fuel vapor. When the engine starts, the excessively rich air-fuel mixture can cause difficulty in starting or even stalling. 2. Fuel vapor leakage, charcoal canister solenoid valve stuck closed: If the solenoid valve remains closed, the fuel vapor stored in the charcoal canister cannot be released, leading to increased pressure in the fuel tank. Eventually, the fuel vapor may leak out through the pressure relief valve in the fuel tank cap.
