Will a car be affected if it is not driven for half a month?

If a car is not driven for half a month, it can have several negative effects. Firstly, it may impact the battery's charge and the lifespan of the tires. Secondly, it could affect the longevity of the engine and braking system. The car's battery is charged while driving under normal circumstances. If the car is not driven for half a month, the battery's charge may decrease. When parked, the vehicle's own weight can cause uneven pressure on the tires, leading to potential deformation. For the engine, prolonged parking may result in oil leakage or coolant deterioration. Some parts of the engine use polymer gaskets, which require oil for lubrication and the vibrations generated during engine operation to distribute pressure evenly. If these gaskets do not receive lubrication or vibration for an extended period, they may deform. Additionally, when a car is parked for a long time, the handbrake is usually engaged. Keeping the handbrake tightly engaged for an extended period can cause the brake pads and brake discs to stick together, thereby reducing the lifespan of the braking system.
Leaving a car unused for half a month can really have negative effects. Every time I return from a business trip lasting about two weeks, I encounter some issues. The most noticeable is the battery problem—due to self-discharge, the battery voltage drops quickly, making it particularly difficult to start the engine or even causing failure to start. Tires are another major issue; if left stationary, insufficient tire pressure can lead to deformation, causing imbalance while driving, which is very dangerous at high speeds. Additionally, engine oil and fluids can stratify and deteriorate if not circulated for a long time, increasing wear during engine startup and shortening the engine's lifespan. Moisture buildup in the brake system can cause rust and sticking, raising the risk of accidents. It's best to start the car at least once a week and drive a few kilometers to allow the alternator to recharge the battery and lubricate the systems. Before long-term parking, check tire pressure and fluid levels, and ensure the battery connections are clean.
