Leaving a car unused for two months can have negative effects, such as tire deformation, loss of air pressure, battery drain, and potential body corrosion. Below are the impacts of prolonged car inactivity: Effects of prolonged inactivity on tires: If tires remain stationary for an extended period, it can affect the bottom part. Considering the lifespan of car tires, even with prolonged pressure, not driving for two to three months—or even up to six months—won’t cause significant damage. However, it may shorten the tire’s normal lifespan by a few months. Effects of prolonged inactivity on the battery: If the car is left unused for a long time, it’s necessary to disconnect all electrical devices connected to the car, such as dashcams. If these devices continue to draw power, they will steadily drain the battery, leading to potential battery depletion.

I once left my car parked at home for two months without moving it, and that experience taught me it can have significant impacts. Mainly, the battery can completely die, especially with modern cars having so many electronic devices that drain power quickly. Additionally, tires under prolonged pressure may deform, particularly in the same spot, leading to discomfort and potential noise when driving. The engine oil can settle, and moisture condensation may cause internal rusting, increasing wear upon restarting. Brake discs can also rust, especially if parked in damp conditions after rain, making the first few brakes squeaky. So, it's advisable to start the engine and drive for about ten minutes every few weeks to protect the battery and engine. If that's not possible, it's best to have a friend drive it occasionally or disconnect the battery's negative terminal to avoid drainage. In short, like people, cars can develop issues from inactivity, so regular movement is essential.

As an office worker, I left my car parked for two whole months due to business trips, and was shocked when I returned. The battery was basically dead and needed replacement. The tires looked okay but felt uneven after driving a couple of laps—definitely some flat spots. What’s worse, the engine struggled to start and buzzed for a while, probably because the oil had thickened. I looked up the reasons online: solidified engine oil accelerates wear, rusted brakes compromise safety, and even rubber belts and components age faster. Prevention is actually simple—just hook up a smart battery charger or take a short drive every month to keep the car moving. My advice to fellow car owners: don’t slack off. If your car sits for over a month, find a way to maintain it, or the repair costs will hit you hard.

Leaving a car unused for two months is indeed problematic. The battery is most likely to die, and the tires may develop flat spots from prolonged pressure. Moisture buildup in the engine can corrode components, while settled oil may cause rough operation. Rust on brake discs can lead to screeching noises or even failure during initial use. To prevent these issues, start the engine periodically for 15 minutes to disperse moisture, or use equipment to lift the tires and avoid flat spots. Simply put, keeping the car in motion is far better than letting it sit idle.
