What Happens to Your Car When It Sits?

July 13, 2020

Your car is a well-oiled machine. At least that’s what it should be. That’s because when the car is maintained and run regularly, its systems remain in good running order. When it sits idle for long periods of time, however, bad things can happen. Let’s look at what occurs to your car when it sits.


A car battery recharges when you drive. When your car is not used, the battery drains energy. Especially if the weather is cold; batteries cannot recover as easily in colder temperatures. When you go to start your car, you will notice that nothing happens. The battery is “dead.”

Your car’s electrical functions, like its computer, can also act to drain the battery, as can faulty wires or electrical connections.

Gaskets and Seals

Gaskets and seals are made of rubber and when they are not regularly lubricated or used, they become dry and brittle. This can cause cracks, tears, or decomposition to occur, leading to leaks and potentially the loss of important fluids. Even if damage to the gaskets and seals is not obviously visible, they can fail and often create problems once the car engine is started.


What happens to your car when it sits is that the weight of the car on tires that remain in a stagnant position for an extended period of time will cause them to flatten against the ground. Once a tire gets a flat spot, it is useless and must be discarded. A tire with a flat spot cannot be revived.

Like gaskets and seals, tires are also made of rubber, and if not used, will become dry and brittle. Cracks and air holes will appear. You should not trust your driving safety to tires on a car that sits idle for an extended time.


Your car’s gas tank is not airtight, and when gasoline mixes with air, it can destabilize over a period of time. Once it degrades, it can either damage your engine, or not enable you to start the car.

Fuel & Brake Lines

Internal components such as your fuel and brake lines can corrode over time when your car sits. This leaves them highly susceptible to leaks or breakage once your drive your car again.


What happens to your car when it sits is an atomic reaction called oxidation that occurs between the oxygen in the air and the iron in your vehicle. In other words—rust. When a car is in regular use, the air moves around it and rust is less likely to occur.


Moisture inside your car can quickly create mold problems on your leather interior or other areas of your vehicle. In addition to damage the mold or mildew can cause, your car will have an unpleasant odor when you return.

Rodents & Insects

An idle car can look like a great new home to mice, bugs and other creatures, and you surely don’t want them to set up housekeeping in your vehicle while you’re away.
