1. Oil filter. Not replacing the oil filter for a long time can cause to become clogged and restrict oil flow, possibly leading to car engine problems or damage.
2. Air cleaner element. If the air filter element becomes clogged with dust and dirt, the proper amount of air will not reach the engine leading to a reduction in horsepower and poor gas mileage.
3. Battery fluid. Using a battery with low fluid levels can lead to battery drainage, overheating or even exploding.
4. Car brake pads/Brake lining. Using brake pads and linings past their service limits can lead to loss of braking effectiveness and accidents.
5. Brake hoses. Using brake hoses in poor condition can cause them to suddenly burst, possibly leading to the complete loss of braking power and accident.
6. Tire. The decrease in tire pressure can go unnoticed. Use of a car with low tire pressure or worn tires can lead to car sliding, tire blowout and even an accident.
7. Coolant. Continue use of insufficient or dirty coolant from lack of replacement over a long period can lead to overheating or radiator corrosion.
8. Engine oil. Continued used of insufficient or dirty engine oil from lack of replacement over a long period can lead to engine problems or damage.
9. Brake fluid. Continued used of insufficient or dirty brake fluid from lack of replacement over a long period can lead to loss of braking effectiveness, which may result in an accident.
10. Window wiper blades. Using wiper blades in poor condition can make it hard to see forward, and may lead to an accident.
11. V-belt. Using a loose or worn V-belt can lead to breakage, which may cause the battery to go dead or the engine to overheat.
