Will Insurance Companies Compensate for Flood-Damaged Cars Due to Natural Disasters?

Insurance will not compensate for a brand new car in the case of flood damage due to natural disasters. Here are the extended details: Introduction to Vehicle Damage Insurance: The provisions in vehicle damage insurance state: The insurer is responsible for compensating losses to the insured vehicle caused by lightning, hail, heavy rain, floods, tsunamis, etc., during the use of the insured vehicle by the insured or permitted drivers. Since flood-damaged cars fall under vehicle losses caused by heavy rain, they are eligible for compensation. However, it's important to note that there is an additional clause in the insurance policy: damages caused by restarting the engine after water ingress are not covered. This means if the car has already been flooded and the driver still forcibly starts the engine, this constitutes improper operation, and the insurance company has the right to refuse compensation. Introduction to Water Wading Insurance: Water wading insurance applies when, while driving, you see standing water on the road and judge that the vehicle can pass through, but the judgment is incorrect, leading to damage while the car is in the water. In such cases, if you have purchased water wading insurance, you can apply for compensation.

Can Dual Clutch Transmissions Perform Launch Control?

Due to the dual clutch transmission having two clutch plates, which experience severe friction during launch control, many vehicles equipped with dual clutch transmissions cannot perform this maneuver. Below is additional information: Manual Transmission Launch Control: The manual transmission is the earliest and most durable type of transmission on earth. Its structure is very simple yet extremely robust, making it widely used in budget vehicles. In fact, manual transmissions are the most suitable for performing launch control, whether in sports cars or economy cars, with identical operation methods. There are two techniques for manual transmission launch control: one involves simultaneously pressing the brake and accelerator, then releasing the brake while engaging the gear and releasing the clutch, resulting in tire roar. The alternative method is releasing the handbrake while engaging the clutch, which is easier than releasing the foot brake. Automatic Transmission with Torque Converter Launch Control: Although automatic transmissions with torque converters have soft connections and lower power transmission efficiency, they can still perform launch control, though not as impressively as manual transmission vehicles with the same displacement. The operation method is similar to manual transmissions, except without the need to release the clutch.

Why Did the Steering Wheel Suddenly Stop Turning?

There are several reasons why a car's steering wheel may become immovable: the steering lock mechanism is activated when the car is turned off; the steering gear lacks lubrication, the steering gear rubber boot has come off, or the steering gear teeth are loose. Below is additional information: Steering Lock Mechanism: The steering wheel may become immovable when the steering lock is activated after the car is turned off. If the steering wheel is turned while the car is off, the steering mechanism will automatically lock, making the steering wheel immovable. This issue can be resolved by turning the ignition key while simultaneously turning the steering wheel, which will release the steering lock and allow the car to start normally, with the steering wheel functioning as usual. It's important to note that if the brake pedal is pressed repeatedly while the car is off, it may also become stiff. This happens because repeatedly pressing the brake pedal while the car is off expels air from the brake booster, creating a vacuum inside, which makes the pedal hard to press. This is a normal occurrence, and the brake will return to normal once the car is started. Steering Gear Lacking Lubrication: If the steering gear lacks lubrication, the rubber boot has come off, or the gear teeth are loose, the steering wheel may also become immovable. In such cases, it is advisable to visit a repair shop or a 4S dealership for professional inspection and repair.
