If your car is left unused for a few weeks, several things can happen. To prevent these problems, it is recommended to start and run the car for a few minutes every few days or at least once a week. If possible, store the car in a dry, cool place and fill up the fuel tank before parking the car to minimize fuel degradation.
The battery of the car may discharge over time due to various electronic components that are still drawing power from the battery even when the car is not in use.
Flat spots on tires
The weight of the car pressing down on the same spot of the tires for an extended period can create flat spots that may cause vibrations while driving.
The fuel in the tank can degrade over time, especially if the car is left sitting for a long time without being driven. This can lead to problems such as hard starting, rough idling, or even engine damage.
Various fluids, including engine oil, brake fluid, and coolant, can become stagnant and lose their effectiveness when a car is left sitting for an extended period. This can cause problems such as engine damage, brake failure, or overheating.
If the car is left in a damp or humid environment, it can lead to rust forming on the metal parts of the car, especially on the brakes and exhaust system.
