If a new car is left outdoors exposed to sun and rain, its lifespan is about one year, after which the battery will be completely drained, making the car unable to start. Below is an introduction to the related issues: 1. Accelerated Battery Damage: When the battery discharges to a low level, the damage intensifies, reducing both its capacity and usable lifespan. 2. Premature Failure: This can cause the battery to enter a failed state ahead of time. Below are the issues that may arise from long-term outdoor parking: 1. Oil Oxidation and Deterioration: Generally, the engine oil in a new car has a shelf life of one year inside the engine. Due to some contamination in the engine oil, prolonged idleness can accelerate oxidation and deterioration, especially if moisture like water vapor enters, which can quickly emulsify the oil. 2. Brake System Corrosion: Long-term inactivity of the brake system makes it prone to chemical reactions with water vapor and oxygen in the air, leading to corrosion. This affects braking performance, and severe corrosion may even cause direct damage to the brake system.

As a new car owner, I noticed significant paint fading and yellowing after parking my car outdoors for just a few years, along with hardened and cracked rubber seals. Exposure to sun and rain accelerated rusting on metal components, such as rims and the chassis, which are prone to corrosion. Once, the door lock got stuck after a heavy rain. I consulted experts and learned that outdoor parking typically shortens a car's lifespan by three to five years. While a new car normally lasts around fifteen years, outdoor conditions may reduce this to ten to twelve years. They recommended washing the car body monthly and using UV-protective car covers, especially in tropical regions. Regular waxing and applying rust inhibitors can significantly extend the car's life, saving the hassle of frequent repairs. Now, I spend some time each week checking tire pressure and wiper condition.

Having repaired cars for many years, I've seen numerous examples of new vehicles developing issues from prolonged outdoor parking. Extended exposure leads to moisture-induced short circuits in electronic components like sensors and wiring, reduces battery life by an average of two years, and frequently causes wiper motor burnout. Rust on the chassis is the most common hidden danger, potentially leading to suspension failure. With diligent maintenance—quarterly dust removal and lubrication—the vehicle's lifespan can extend to about twelve years; however, complete neglect may render a new car unusable within five to six years. Remember to regularly check for debris accumulation in bumper gaps to prevent drainage hole blockages. These small habits can save you significant money.

From the experience of using a family car, leaving it outside for just a few days results in accumulated dust and leaves. The high summer temperatures cause the interior to age and harden. Once, the buckle of the child seat's safety belt rusted and couldn't be opened. A new car left exposed outdoors for five years ends up in a similar condition to one kept indoors for ten. Later, we built a simple shed in the yard, which worked very well. After each rain, wiping dry the window seams helps prevent rust. The estimated lifespan is reduced to about ten years, three years less than if kept in a garage. If parked outdoors long-term, remember to cover it with a tarp and inspect it regularly.
