What are the most often replaced auto parts? The parts that may have to be replaced on your vehicle will depend somewhat on the year/make and model of your vehicle, the kind of driving you do, the number of miles you put on your vehicle annually, and the climate where you operate your vehicle.
Normal wear and tear will cause certain auto parts to wear out at a fairly predictable rate, while other factors such as how you drive your vehicle and where you drive your vehicle can increase or decrease the rate at which certain parts wear out and have to be replaced. Even your driving style can be a factor. An aggressive driver will obviously wear out the brake pads on their vehicle much more quickly than someone who is a more normal driver.
The following list of parts that are often replaced is based on frequency (most often to least often), and are based on the average wear a typical vehicle owner should experience under normal driving conditions. It doesn’t mean the parts on your car will necessarily have to be replaced at the following time or mileage intervals, but it can give you an idea of what to expect down the road as your vehicle accumulates mileage and wear

Oil and Oil Filter – Every three to six months, or every 3,000 to 5,000 miles
Air filter – Every three or four years, or 30,000 to 50,000 miles. Filter life can be much less if a vehicle is driven on dusty gravel roads.
Brake Pads – Every three to five years, or 30,000 to 70,000 miles. Replacement frequency can vary greatly depending on the type of vehicle (larger, heavier vehicles wear out their brake pads more quickly than smaller vehicles), the type of original equipment brake linings (semi-metallic and ceramic linings usually last much longer than nonasbestos organic linings), the type of driving you do (stop-and-go city driving increases pad wear dramatically), and your driving style.
Battery – Every four to five years (mileage doesn’t matter). Less in really hot climates (maybe only three years).
Headlights bulbs – Five to seven years, depends on how much nighttime driving you do. Driving on rough, bumpty roads can also shorten the life of conventional bulbs with filaments (no effect on Xenon bulbs which do not have a filament inside, or LED taillights
Tyres – Every five to seven years, ending on number of miles driven annually, the type of driving you do, and the wear rating on the tires (a higher wear rating number means the tire should last longer). Hard cornering and aggressive driving can increase tire wear dramatically. So can wheel misalignment.
Brakes Calipers – Typically last 100,000 miles or more, but eventually succumb to internal corrosion and deterioration of the rubber seals. Need to be replaced is leaking or sticking. Often replaced at second brake job (seldom necessary at first brake job).
