The reasons why the Nissan Sylphy fails to start are battery failure, excessive carbon buildup, and lack of antifreeze. Battery failure: Battery failure may be caused by a drained battery due to reasons such as leaving the headlights on for a long time, or the battery reaching the end of its lifespan. Additionally, installing xenon headlights, high-power audio systems, or DVD players can also lead to vehicle circuit malfunctions. It is generally recommended to replace the car battery every 2 years. Excessive carbon buildup: When the vehicle experiences incomplete combustion due to poor gasoline quality or short driving distances, it can lead to excessive carbon buildup, which may also cause the vehicle to fail to start. The solution is to frequently drive on highways to ensure complete gasoline combustion and reduce carbon buildup. Lack of antifreeze: Leaks in the antifreeze system or the use of inferior antifreeze can cause the entire cooling system to freeze in extremely cold winter conditions, leading to a cracked engine and rendering the car's water pump inoperable. This results in the vehicle failing to start and may damage other engine components. It is essential to promptly inspect and replace the antifreeze, ensuring the appropriate type is used.

High-quality car films, due to their strong adhesive and superior quality characteristics, can be more challenging to deal with. In this case, it's best to use professional tools like a glue removal knife for removal.
