What Are the Effects of a Car Sitting Unused for a Long Time?
2 Answers
Leaving a car unused for an extended period can have the following effects: 1. Oil seal failure and aging: When a car is not used for a long time, the contact force around the oil seal becomes uneven, causing parts to deform and eventually become unusable. Additionally, failed or aged oil seals can lead to oil leaks. 2. Deterioration of engine oil or other fluids: Organic substances in the car cannot be stored for long periods, as they may mix or deteriorate. 3. Brake system issues: If the car remains in a braked state for too long, the brake pads and discs may fuse together, resulting in brake system failure.
I was away on a business trip for half a year without touching my car, and when I came back, I found it wouldn't start at all—the battery was completely dead. The tires were also flat because it had been parked in the same spot for too long, causing the treads to deform. The engine oil had turned sticky, making the engine prone to wear and rust. Even worse, the brake discs had developed red rust, making a screeching noise when braking. There was also a musty smell inside, and small black spots had grown on the seats. If you're not going to drive for a long time, it's recommended to have someone start the engine for a few minutes each week, inflate the tires properly, or use a battery maintainer. Looking back now, I spent hundreds of dollars on repairs—what a waste. I definitely don’t want to go through that hassle again next time.
