How Long Can a Private Car Be Left Undriven Without Issues?

Private cars can be left undriven for up to one month. It is recommended to drive the car at least once a month for no less than half an hour each time. Prolonged inactivity can lead to battery discharge. Hazards of long-term parking: Tire aging: The contact points between the tires and the ground are prone to aging. The contact points between the tires and the ground may deteriorate, and even the wheel rims could develop subtle deformations, making the car feel unstable when driven. Frame deformation: Parking on uneven surfaces can cause severe issues, such as doors becoming difficult to open or failing to seal properly. This can also lead to an unstable chassis, increased noise, and suspension oil leaks during driving. Precautions for vehicle parking: Even when the car is locked, the battery still experiences a small current drain, leading to power loss. It is advisable to disconnect the negative terminal of the battery if the car will be parked for 15 days or longer. Always choose flat surfaces for parking, preferably in areas monitored by cameras, and avoid parking near garbage piles or tall grass.
Having driven for over a decade, I've found that private cars really develop issues when left unused for extended periods. If it's just parked for a week or two, there's no need to worry at all—starting it up and taking it for a spin will hardly have any impact. However, if left idle for over a month, problems start to emerge: the battery can easily drain because onboard electronics like the anti-theft system still draw power quietly; tires under prolonged pressure may deform, leading to imbalance or air leaks; and engine oil that has settled will provide poorer lubrication, increasing wear upon restart. Once, after leaving my car parked for three months during a business trip, it wouldn't start at all when I returned, forcing me to call a tow truck for repairs, which cost quite a bit. I recommend starting the car regularly for at least ten minutes to recharge the battery and avoiding parking it for more than a month and a half.
As an average car owner, I believe the duration of parking depends on specific circumstances. For short periods like 10-15 days, it's usually fine, but my friend experienced a dead battery and soft tires after leaving it for a month. My current practice is: if I know the car will be parked long-term, I fully charge the battery, inflate the tires properly, park in a shaded area, and cover it with a car cover. This way, parking for 2-3 months is manageable. However, if left unused for over six months, risks like brake disc rust and coolant deterioration increase significantly. It's best to have someone start and drive it for a few minutes weekly to avoid future issues.
From my experience, leaving a family car unused for too long can indeed cause trouble. A week or two is fine, but beyond three to four weeks, problems start to arise—most commonly a dead battery and tire issues. I once left my car parked for forty days and had difficulty starting it, almost causing a serious inconvenience. My advice is not to leave it parked for more than a month. If you must leave it unused for an extended period, ensure the parking spot is secure and dry, start the engine monthly to take a short drive and warm up the car, keeping all parts functioning smoothly. Long-term parking also increases the risk of small animals nesting or parts deteriorating, so be extra cautious.
