Is it okay to leave a car unused for a month?

There are impacts. Prolonged parking of a vehicle can cause tire deformation, resulting in noticeable rolling impacts when the vehicle is started again. Secondly, the battery will suffer severe depletion. When the battery's self-discharge reaches a certain level and remains undercharged for a long time, the plates inside the battery can become sulfated, shortening its lifespan. It is recommended to start the vehicle at least once a week. Below is relevant information: Battery lifespan is significantly shortened: The vehicle's battery charges while driving. If the car remains unused for a month, the battery cannot recharge. However, it continues to consume power, as electronic devices like the anti-theft module remain operational even after the engine is turned off. For older vehicles, the battery might die within 2-3 weeks. Tire deformation: When a car is parked, the entire weight is borne by the parts of the four tires in contact with the ground, causing compression and deformation in these contact areas. The longer the car remains parked, the harder it is for these deformed areas to recover, altering the weight distribution around the tires and creating uneven rolling radii, leading to tire imbalance. Once the car enters high-speed driving, body vibration can occur, accelerating tire wear and posing potential safety hazards.
