Is it normal for the engine warning light to come on in a new car?

Sensor issues: The sensors mentioned here include coolant temperature, crankshaft position, air flow, intake air temperature, oxygen sensors, etc. When these sensors are damaged, have poor contact, or experience signal interruption, the car's ECU cannot accurately obtain engine data, which will cause the engine warning light to come on. Maintenance issues: Poor engine maintenance is the most common reason for the engine warning light to illuminate. Vehicles have specific maintenance cycles, and if the owner does not perform maintenance on schedule, coupled with poor driving habits, it will increase the burden on the engine's operation. Eventually, the warning light will come on as a reminder to take care of the vehicle. Fuel quality issues: The fuel quality here includes both fuel and engine oil. The fuel added to a car usually has a specific grade, and engine oil can be semi-synthetic or fully synthetic. Manufacturers generally recommend which grade of fuel and type of engine oil to use. If the owner does not follow these recommendations, it will lead to engine wear over time.

Is free touch-up paint provided for new car scratches within one year?

New car scratches are not eligible for free touch-up paint within one year. Below are relevant details: 4S store touch-up: If you go to a 4S store for touch-up paint, it will be charged according to standard rates. However, if the scratched area is not noticeable and requires spot painting by the 4S store, this service may be provided free of charge. High-temperature baking: Minor scratches or blemishes on new cars do not necessarily require touch-up treatment. It's important to understand that touch-up paint treatment is completely different from the original paint. Original paint is applied and then the entire vehicle is baked at 200 degrees Celsius. However, many components on a finished vehicle cannot withstand such high temperatures. Even when using specialized touch-up paint during repairs, the baking temperature is maintained at around 70 to 80 degrees Celsius, and the touch-up paint can only treat the surface layer. Therefore, unless absolutely necessary, touch-up painting is not recommended.

What items are required for the second maintenance of a new car?

The items required for the second maintenance of a new car include: Engine oil and oil filter: If using mineral oil, semi-synthetic oil, or full synthetic technology oil, the maintenance interval is generally 5,000 kilometers or six months. If using full synthetic oil, the maintenance interval is 10,000 kilometers or one year. Replace the engine oil and oil filter, check the cleanliness of the air filter and cabin air filter, and then decide whether to blow them clean or replace them directly based on the actual condition. Air filter: At every 20,000 kilometers, generally replace the air filter, cabin air filter, brake fluid, coolant, spark plugs, and other components. Additionally, rotate the four tires based on their wear condition. Various fluids: At every 40,000 kilometers, it is necessary to replace all types of vehicle fluids, replace the timing belt/chain, clean the throttle body, fuel injectors, and other components, and check the condition of wear items such as brake pads and tires for replacement as needed.

What is the issue when four-wheel drive is turned off?

The indication of four-wheel drive being turned off is not a malfunction, but rather means that the current driving conditions do not require four-wheel drive mode, and two-wheel drive is sufficient. How four-wheel drive works: The four-wheel drive system, also known as the all-wheel drive system, refers to a setup where both the front and rear wheels receive power. It can distribute the engine's torque in varying proportions to all wheels based on road conditions to enhance the vehicle's driving capability. It is commonly denoted as 4X4 or 4WD. Categories of four-wheel drive: Four-wheel drive systems are mainly divided into two types: part-time four-wheel drive (PartTime4WD) and full-time four-wheel drive (FullTime4WD).

How Deep of Water Can a Wrangler Cross?

Wrangler can cross water up to 762mm deep. When fording water, ensure the vehicle moves at low speed and constantly check the water depth. For manual transmission models, use first gear if possible, maintain steady throttle for smooth passage. Automatic transmission models should engage forced low gear or snow mode to increase torque and prevent wheel slip. Avoid aggressive maneuvers and stalling midway. Below are relevant details: Fording Depth: Regular sedans are no match for SUVs in water fording. Sedans typically can't exceed 20cm, with some low-profile models limited to 15cm. Correct Fording Method: Maintain low speed and monitor water depth. Manual transmissions should use first gear with steady throttle; automatics should engage low gear/snow mode to boost torque and prevent slippage. Avoid sudden movements and stalling. After exiting water, perform several consecutive brakes to rapidly evaporate moisture from discs and ensure braking performance.

Can You Buy a Flood-Damaged New Car?

Legitimate 4S stores will not sell flood-damaged new cars. Here are the details: Legitimate 4S stores: 4S stores are relatively standardized and generally do not sell vehicles with potential hazards, but this is not absolute. Some 4S stores may internally sell flood-damaged cars. To some extent, flood-damaged cars can be repaired, but they pose significant safety risks and may have numerous hidden faults. Hazards of flood damage: Damage to the car's internal electronic control systems and various electronic components: For example, water-damaged vehicles can cause corrosion and rusting of the wiring, leading to sudden stalling or brake failure due to short circuits while driving, with unimaginable consequences. Engine damage: When the water level exceeds the engine's air intake, water can be sucked into the engine cylinders. Since water is incompressible, if the engine stalls due to water ingress and is restarted, the immense reverse force can bend the connecting rods and scrape against the engine cylinder walls, potentially rupturing the engine block instantly, resulting in severe engine damage.
