What to Do If You Buy a New Car That Turns Out to Be a Damaged Vehicle?

If you purchase a new car that turns out to be a damaged vehicle, you have the right to request a refund or replacement and seek compensation. Here are some precautions to take when buying a car: 1. Choose a Brand: Selecting an appropriate brand is crucial. For example, some prefer Japanese cars, others German cars, while some favor domestic brands, and others may opt for less common Korean or French cars. Each car series has its unique highlights, so it's important to find the brand that suits you best. 2. Select a Model: Car models can be categorized into sedans, SUVs, MPVs, crossovers, hatchbacks, etc. Choose the model that best fits your personal needs and preferences. For instance, a compact and agile hatchback may be ideal for personal commuting, while families might prefer spacious SUVs, and those with two children could opt for MPVs, often referred to as 'dad cars.' 3. Consider the Price: Since cars are consumable items, it's essential to choose a model within your financial means. Remember that purchasing a car also involves additional costs like purchase tax, vehicle and vessel tax, insurance, and licensing fees. Therefore, always consider the total on-road price of the vehicle to avoid budget shortfalls.

Can You Make a U-Turn at a Roundabout?

Roundabouts do allow U-turns. Requirements for U-turns: 1. Vehicles are prohibited from making U-turns at locations with no U-turn or no left-turn signs/markings, as well as at railway crossings, pedestrian crosswalks, bridges, sharp curves, steep slopes, tunnels, or roads prone to hazards. 2. Vehicles can make U-turns at locations without no U-turn or no left-turn signs/markings, but must not obstruct the normal passage of other vehicles and pedestrians. Roundabout driving requirements: 1. All vehicles must travel counterclockwise around the roundabout facility and exit at their desired direction; 2. Most inner lanes of large roundabouts have dividers to separate motor vehicles from non-motor vehicles. Within motor vehicle lanes, some have two or more lanes for vehicles heading in different directions; 3. Right-turning vehicles must enter the right lane, while straight-going and left-turning vehicles must enter the left lane; 4. Vehicles must immediately reduce speed when approaching a roundabout; 5. When entering the roundabout, the left turn signal must be activated in advance, and when exiting, the right turn signal must be activated in advance before merging into the right lane.

Does changing the license plate without changing the owner count as a transfer?

Changing only the license plate number does not count as a transfer. For a transfer to occur, the vehicle registration must also be updated to the new owner's name. According to the "Motor Vehicle Registration Regulations": Article 18: When the ownership of a registered motor vehicle is transferred, the new owner must apply for a transfer registration at the local vehicle management office within 30 days from the date of delivery. Before applying for the transfer registration, the owner must resolve all traffic violations and accidents related to the vehicle. Article 19: To apply for a transfer registration, the new owner must fill out an application form, present the vehicle for inspection, and submit the following documents and proofs: (1) The new owner's identity proof; (2) Proof and documentation of the ownership transfer; (3) The motor vehicle registration certificate; (4) The motor vehicle license; (5) For vehicles under customs supervision, the "Release Certificate of Customs Supervised Vehicles" or a customs-approved transfer proof must also be submitted; (6) For vehicles past their inspection expiration date, a valid motor vehicle safety inspection certificate and compulsory traffic accident liability insurance proof must also be submitted. It is important to note that when purchasing a new vehicle, the owner must replace the old license plate with a new one as per regulations, and the original plate must be surrendered to the traffic authorities. Additionally, license plates cannot be transferred, meaning the buyer cannot use the original plate.

Will a Faulty Catalytic Converter Affect Fuel Consumption?

A faulty catalytic converter will affect fuel consumption. Its primary impact is on vehicle emissions. Lower emissions indicate more complete fuel combustion and better fuel efficiency. When the catalytic converter fails, emissions increase, and gasoline cannot be fully combusted and utilized, naturally leading to higher fuel consumption. Specific manifestations of a damaged catalytic converter: 1. Increased Tailpipe Pollution: Without the catalytic converter's ability to reduce harmful emissions, vehicle exhaust pollution will worsen. 2. Illuminated Engine Warning Light: When the engine's electronic control unit (ECU) fails to detect or detects abnormal signals from the oxygen sensor, the engine warning light will illuminate. 3. Increased Fuel Consumption and Reduced Power: A damaged catalytic converter affects the oxygen sensor's signal accuracy, preventing the engine from precisely controlling fuel injection. This results in increased fuel consumption and reduced power. 4. Poor Exhaust Flow and Engine Overheating: Catalytic converter failure is often caused by clogging, which leads to the accumulation of high-temperature exhaust gases, increasing the risk of engine overheating. 5. Carbon Buildup: As the air-fuel ratio in the combustion chamber becomes severely imbalanced, incomplete combustion generates excessive carbon deposits, accumulating in the cylinder and exacerbating chronic engine issues.

What procedures are required for changing a car's color with a wrap?

The documents required for applying to change the color of a motor vehicle include: the "Motor Vehicle Change Registration Application Form," original and photocopies of the identity documents of the vehicle owner and agent, the original vehicle registration certificate, and the original vehicle license. Additionally, any fines must be paid before changing the vehicle's color. According to Article 6, Chapter 2 of the "Road Traffic Safety Law," if the area of color change on a motor vehicle does not exceed 30%, no change registration is required. Conversely, if it exceeds 30%, it must be filed and registered within 10 days after the color change. Precautions for changing a vehicle's color with a wrap: Before preparing to change the color of a motor vehicle with a wrap, it is necessary to consult the local vehicle management office where the vehicle is registered to confirm whether the region permits changing the vehicle's color using a wrap. If the region does not support this method, the change cannot be filed, and the wrap must be completely removed to restore the vehicle's original color. Additionally, according to Article 10 of the "Motor Vehicle Registration Regulations," vehicle owners are no longer required to apply in advance to the vehicle management office. They can first change the vehicle's color, install body kits, replace the engine, etc., and then apply for change registration with the vehicle management office. According to Article 10, for registered motor vehicles, the owner must apply for change registration with the local vehicle management office in the following cases: Changing the vehicle's body color. Replacing the engine. Replacing the body or frame. Replacing the entire vehicle due to quality issues. Changing the use nature, such as converting a commercial vehicle to a non-commercial vehicle or vice versa. The vehicle owner's residence moves out of or into the jurisdiction of the vehicle management office. Furthermore, according to Article 15 of the "Road Traffic Safety Law of the People's Republic of China": Police cars, fire trucks, ambulances, and engineering rescue vehicles must be painted with designated patterns and equipped with alarms and signal lights as required. Other motor vehicles are prohibited from painting, installing, or using patterns, alarms, or signal lights that are exclusive to or resemble those of the aforementioned vehicles.

Will the car battery run out of power if the car is not used for a long time?

If a car is not used for a long time, the battery will definitely run out of power. Car batteries have a self-discharge characteristic. Even when the car is not in use, the battery's charge will gradually deplete, leading to a loss of power. However, the extent of power loss varies—it could be completely drained overnight or take several months to fully discharge. Here are some related precautions: 1. Replace the battery every 3 years: Generally, a car battery should be replaced after about 3 years of use. Most modern cars are equipped with maintenance-free batteries, which have a clean appearance and are easy to inspect. These batteries come with an inspection window—normally displaying green when in good condition. If the color changes (varies by manufacturer), it indicates the battery has reached the end of its lifespan and needs immediate replacement. 2. Pay attention to warning signals: The best way to prevent sudden battery failure is to be alert to the warning signals from the car. For example, if the starter motor does not turn or turns weakly, making it difficult to start the engine. 3. Poor low-temperature storage capacity: The electrolyte in the battery is less active at low temperatures compared to high temperatures, and its resistance is higher. As a result, the battery's storage capacity is relatively weaker in cold conditions. This means that, given the same charging time, the battery will store less power in cold weather than in warm weather. This is also why it is more difficult to start a car in winter.
