How Often Should a Sedan Be Driven When Parked for Long Periods?

[StTanner]

It is recommended to start the vehicle at least once every fifteen days, keeping the engine running for over half an hour, and preferably moving the car or driving a short distance. Additional details are as follows: 1. Battery Issues: The vehicle battery is the most susceptible to problems when the car is parked for extended periods. Even after the car is locked and parked, although most electrical systems enter a dormant state, certain components such as the anti-theft system still require power. This results in a small but continuous dormant current drain. Over time, this can lead to a significantly depleted battery, potentially preventing the engine from starting. Therefore, it is essential to periodically start the engine to recharge the battery and avoid excessive discharge. 2. Tire Issues: Prolonged parking can cause the tires to bear weight at the same spot continuously, which may lead to tire deformation over time. This can result in vibrations when driving. To prevent this, it is advisable to move the vehicle periodically to distribute the weight more evenly across the tires.

I've been repairing cars for over 20 years and have seen many vehicles develop problems from long-term parking. Tire deformation, battery leakage, and brake rust are common issues. It's best not to leave your car parked for more than a week under normal circumstances, and even better to start it weekly. Take the car out for a 20-30 minute drive to warm up the engine and get the lubricated components moving, especially the drivetrain and suspension systems. This allows the oil to circulate and prevents congealing. If left stationary for too long, tire pressure gradually decreases, wheels may become misaligned, and the battery can easily drain - leaving you with a big problem when it won't start. If you absolutely can't drive it, park in a cool, dry place and use supports to reduce tire load. Make it a habit to regularly check tire pressure and fluid levels to save on repair costs. These may seem like small things, but just like people, cars develop problems when they don't move.

I often leave my car parked when I'm busy with work, but I make sure to drive it at least once a week. Usually, I take it out on weekends for grocery shopping or a short drive to prevent battery drain—otherwise, leaving it idle for too long might result in a completely dead battery. It's best not to leave it unused for more than two weeks, as prolonged inactivity can cause fuel in the lines to degrade and clog the fuel injectors. If the engine sits unused for too long, metal parts can oxidize and rust, and starting it might even damage internal components. In summer, parking outdoors exposes the car to high temperatures and humidity, which accelerate corrosion of electrical wiring. Once, after leaving my car untouched for a month, the AC compressor seized up, leading to costly repairs. I recommend driving for 15-20 minutes each time to keep all systems active and avoid minor issues snowballing into major problems. When parking, choose level ground, close doors and windows properly, and minimize dust and pests entering the engine bay.

I've discussed this with my friends, and we all agree that a car should be moved every 10 days or so. Take it for a short drive, like going to the supermarket or circling the neighborhood a few times, which can be done within half an hour. The main concerns are tire deformation and battery drain, as a stationary car might trigger fault warnings upon startup. If left unused for over two weeks, the fuel may degrade, potentially damaging the fuel pump. Sensors in the electronic systems could also malfunction. A car is like a machine; prolonged inactivity can cause parts to stick or corrode. When parking, avoid pulling the handbrake too tightly to prevent the brake pads from rusting. It's best to drive the car at least twice a month to ensure the engine runs smoothly. Checking the wipers and lights while you're at it is convenient and worry-free.

When my husband is on business trips, his car often sits idle, so I help by starting and driving it occasionally. It's generally advised not to leave a car parked for more than a week, as the battery can drain quickly, and the engine and belts may stiffen. Ideally, drive the car for about 20 minutes within two weeks to let the engine warm up and circulate oil to all parts. Prolonged parking can cause tires to flatten, and driving at high speeds with insufficient tire pressure is dangerous. Rubber components on the car, like wipers and seals, age faster and may deform. Once, after leaving the car unused for too long, it made creaking noises when starting—turned out the suspension had rusted. Always choose a good parking spot; avoid parking under trees or in waterlogged areas, as damp conditions can corrode the chassis. After each drive, ensure the tires are properly inflated and the dashboard functions are normal. Simple steps like these can extend the car's lifespan.
