An overview of the most common defects in car parts

The condition and longevity of your car largely depends on the maintenance you have done over the years. Fortunately, most types of maintenance are simple and take little time. For example, you may need to change your oil every 5,000 miles (or more often, depending on the owner’s manual). Air and fuel filters should be changed regularly. The fluid level and tire pressure should also be checked regularly. If you work hard on these things, you can keep your car in good shape for many years.

Unfortunately, old age will come eventually, no matter what you do to prevent it. Car parts break and need to be replaced. Below I give you a list of parts that may change over time.

Fuel pump

Your fuel pump is responsible for delivering fuel to your fuel injection system. If it fails, your car’s engine (or more specifically, the combustion chamber) won’t get the gas it needs for the combustion process. If you drive a home vehicle, you can expect the pump to be replaced after about 50,000 miles. If you own a Toyota or Honda, you don’t need to replace it.

The bad news is that this part is usually installed in the fuel tank. Because of this, change takes time. While the pump itself can cost $200, the labor can cost twice as much.


Not delivering is expensive. While minor problems like leaks are easy and inexpensive to fix if caught early, failure usually means replacing the entire assembly. This is because many transmission shops are not willing to do a complete overhaul due to the time involved.

Transmissions installed in newer vehicles can last over 100,000 miles. Note that this is only a guide; some fail very quickly. Kit replacement costs can exceed $2,500, including parts and labor.

Brake system

The more aggressively you ride, the more you need to improve your brakes. Most braking operations focus only on the brake pads. The pads wear out and need to be replaced before they rub against the rotors. If this happens, need to Auto parts machining  the rotors. Brake pads for light vehicles only need to be replaced every 50,000 miles. In contrast, heavier SUVs may need to be replaced after 35,000 miles. Pillows usually cost less than $80 and can be used at home. However, if the rotors require machining, you need the tools and expertise of a mechanic. Expect to pay up to $500 (and possibly more).


Car batteries usually last three to six years. Although their durability largely depends on the brand you buy, the climate where you live can also play a role. High temperatures like Arizona can shorten battery life significantly, usually up to three years.

Fortunately, batteries are cheap (usually under $100) and can be easily replaced without the help of a mechanic. There are many other parts and systems that can break down and eventually require repair or replacement. For example, your car’s engine should run well past 100,000 miles, but that depends on your driving habits and how diligent you are about changing the oil. Your catalytic converter should last more than 150,000 miles, but a better fuel mixture in the engine can shorten its life.

Think of your car as an investment. If they fail, you may need to replace the parts. The most important thing is to keep up with routine maintenance (e.g. check fluid levels, change oils, change filters, etc.) and fix problems quickly. This prevents small problems from growing into large repair costs.
