Will There Be Any Impact If a Car Is Not Driven for a Month in Summer?

[May]

Not driving a car for a month can cause problems. Leaving a car unused for an extended period can be harmful. If the vehicle must be parked for a long time, it is best not to leave it outdoors. A better option is an underground garage or a relatively enclosed space. The issues that may arise from not driving a car for a month include: 1. Component and Rubber Aging: When a car is parked for a long time, electronic components are more prone to moisture damage, and rubber parts may accelerate aging due to exposure to wind and rain. These conditions can significantly reduce the car's waterproofing and soundproofing capabilities. 2. Battery Drain: A car's battery gradually charges while the vehicle is in use. However, if the car is left unused for an extended period, such as a month, the battery remains in a state of continuous discharge without recharging. This is mainly due to devices like the anti-theft module, which continue to operate even after the engine is turned off.

Last year, I was on a business trip for a whole month, and my car was parked in the open parking space of the residential area. When I returned, I found the battery completely dead and couldn't start the engine, so I had to call for a jump-start rescue. The tires were slightly deformed from being in one position for too long, and I could feel a slight vibration in the steering wheel while driving. The worst part was the rusted brake discs—the brakes squeaked terrifyingly when I first started driving. When I turned on the AC, it blew out a musty smell, and the mechanic said it was due to mold from accumulated water in the AC pipes. The bottled water left inside had deformed, and the chocolate in the armrest had melted into a puddle. Next time, I’ll definitely need to ask someone to start the car weekly if it’s parked long-term—otherwise, it’ll damage the car and cost me more money.

I work in used car appraisal and have seen too many vehicles left parked for long periods. The battery suffers the most damage if the car isn't moved for a month in summer - with so many electronic devices in modern cars, they still drain power when idle, and a depleted battery's lifespan is significantly reduced. When engine oil settles, its lubricating properties deteriorate, causing severe wear during startup. I've seen tires become unusable after just three months of parking - rubber ages and deforms in high temperatures, creating flat spots. The interior takes a beating too - leather seats crack under intense sunlight, and plastic components age faster. Parking under trees is even worse - tree sap and bird droppings corrode the paint, and frequent rain makes the chassis more prone to rust.

My car was parked for a month during summer vacation, and when I retrieved it, the windshield was covered with leaves and branches. The wiper blades had melted and stuck to the glass. The temperature inside the car was at least 60°C, and the wet wipes I forgot to take out had dried into solid blocks. The car key remote stopped working, and only after replacing the battery did I realize the signal loss was due to the battery being completely dead. The door seals had hardened from the sun, making it difficult to close the doors. A friend suggested that I should use a car cover next time, disconnect the battery, and inflate the tires to a higher pressure. Unfortunately, there were no dehumidifiers in the car, and mold spots had formed under the floor mats.

A neighbor in our community left his car parked in the underground garage all summer. When he went to retrieve it, all four brake discs had rusted into a reddish-brown color. The mechanic said he'd need to drive it out and brake hard a few times to wear off the rust, but warned that if the rust was too deep, it could be dangerous. His car's infotainment system also crashed, possibly due to high temperatures causing circuit board solder joints to fail. The most troublesome issue was the gasoline in the fuel tank - stored for over a month, it may have degraded and could affect engine performance. Now we've all learned our lesson: when leaving cars unused for extended periods, we fill up the tank and add stabilizer, inflate tires to the maximum recommended pressure, and cover the windshield with reflective panels.

After returning from a trip last time, the fuel gauge showed a remaining range of 400 km, but the battery voltage was insufficient when starting the engine. It turned out to be an issue with the fuel pump being submerged in gasoline for too long. The mechanic said that when parked for extended periods, gasoline evaporation can expose the fuel pump to air, making it more prone to damage under high temperatures. Dust accumulation on the body had turned into stubborn stains that even a high-pressure water gun couldn’t remove. The tires were underinflated to the point of triggering the tire pressure warning, but fortunately, they hadn’t deformed. Now, I regularly ask a friend to help warm up the car for ten minutes, which also allows the air conditioning system to run and dehumidify. The spare tire in the trunk also needs checking, as rubber ages particularly fast in such hot weather.
