Common Problems with Cars That Sit for Awhile

Leaving your car unused for an extended period can lead to a range of issues, from minor inconveniences to significant mechanical problems. Whether it’s a classic car in storage, a seasonal vehicle, or simply a car that sits idle for weeks at a time, understanding the Common Problems With Cars That Sit For Awhile is crucial for preventing damage and ensuring a smooth restart when you’re ready to hit the road again.

Why Do Cars Develop Problems When Left Unused?

Cars are designed to be driven regularly. Fluids circulate, parts move, and systems operate optimally when in use. When a car sits idle, these processes stagnate, leading to potential issues. From fluids breaking down to rubber seals drying out and critters seeking shelter, inactivity can take a toll on your vehicle.

Common Issues with Inactive Cars

Battery Drainage

One of the most common problems with cars that sit for awhile is a dead battery. Even when the car is off, certain systems continue to draw power, slowly draining the battery over time. This is also known as parasitic drain.

Tire Problems

Tires can develop flat spots when a car sits in the same position for an extended period. The weight of the car constantly presses on the same area of the tire, causing the rubber to deform. This can lead to a bumpy ride and premature tire wear.

Brake Issues

Rust and corrosion can affect brake rotors and calipers, especially in humid climates. This can lead to reduced braking performance, squeaking noises, and potentially even brake failure. Seized brakes are a common issue for cars that have been sitting for a while.

Fluid Degradation

Fluids like engine oil, coolant, brake fluid, and transmission fluid can break down over time, losing their effectiveness. This can lead to reduced performance and potential damage to engine components, cooling system, and braking system. Old fluids can also become contaminated, further exacerbating the problem.

Fuel System Problems

Fuel can evaporate or become stale when a car sits unused for a long time. This can lead to difficulty starting the engine, reduced performance, and potential damage to the fuel system components, such as the fuel pump and injectors. Water condensation in the fuel tank can also cause rust and corrosion.

Pest Infestation

Rodents and insects can find their way into a parked car, seeking shelter and nesting materials. They can cause damage to wiring, upholstery, and insulation, leading to electrical problems, unpleasant odors, and costly repairs.

Rubber Seal Deterioration

Rubber seals and gaskets can dry out and crack over time, especially when exposed to the elements. This can lead to leaks in various systems, such as the engine, transmission, and cooling system.

Exhaust System Corrosion

The exhaust system is particularly susceptible to rust and corrosion, especially in areas with high humidity or road salt. Holes or cracks in the exhaust system can lead to dangerous fumes entering the cabin and reduced engine performance.

How to Prevent Problems with Cars That Sit for Awhile?

Battery Maintenance:

Use a trickle charger to maintain the battery’s charge, especially if the car will be sitting for more than a month.

Tire Protection:

Inflate the tires to the recommended pressure and consider placing the car on jack stands to prevent flat spots.

Fluid Changes:

Change all fluids before storing the car for an extended period, ensuring they are fresh and in good condition.

Fuel System Care:

Fill the fuel tank to prevent condensation and add a fuel stabilizer to prevent the fuel from going stale.

Pest Prevention:

Use rodent repellent and seal any openings where pests could enter the car.

Cover and Protect:

Store the car in a covered area, such as a garage, to protect it from the elements and pests.

“Regular maintenance is key, even for cars that aren’t driven regularly,” says John Miller, a seasoned automotive engineer with over 20 years of experience. “Taking preventative measures can save you a lot of headaches and expensive repairs down the road.”
