Most Common Defects in Aging Cars

Just like any other machine, anything can go wrong with your vehicle as it ages. After years of usage, your vehicle will show signs of wear and tear. With aging, it’s normal, but you might want to tend to its defects no matter how old it already is so that you don’t have to pay for automotive recall.

Vehicles that have been determined by NHTSA as a safety risk at the road, such that they fail to meet the minimum safety standards, can undergo a car recall. You can even try to revive your now-ancient car. For now, here are the most common issues aging cars face:


Once you hear an unusual noise, smell something burning, or detect a different performance in your brake, stop right away. Brakes need periodic maintenance, but when it comes to older cars, you might experience damages more frequently. Specifically, beware when your brakes squeal or vibrate.

Addressing the problem doesn’t have to be expensive all the time. There might be moisture or dust trapped somewhere, needing only a fluid replacement kind of repair. Just make sure you familiarize yourself with the signs of brake issues to avoid the dangers of faulty brakes.


These include the climate, exhaust, drive, and electrical systems. When it comes to emissions, older cars tend to produce higher levels of everything except carbon dioxide. There has been much deliberation over which car is greener—the classic or the modern. Between old and modern, the latest emits more carbon dioxide (CO2) than the old. However, the classic versions emit more of the other exhausts, so decide which is way better for you. This way, you know whether you should buy a new car or revive the old one.

An aging car is more prone to electrical system damages too. Many other parts of the vehicle, such as charging systems, air-condition, and more, rely on the electrical system to function. If you notice your fuses are blowing most often and you have a faulty alternator, dead battery, damaged relay, and shorted wires, then have it repaired immediately. 


Engine issues usually are about the major, minor, and cooling engines. The major engine is damaged when overheated and with a broken timing belt, hydrolocked engine, and low engine oil levels. 

The internal combustion engine, in general, wears out when its various moving parts undergo excessive friction and heat. The cylinder bores over time will be damaged by the piston rings because the rings move up and down multiple times.

A damaged engine will cause the aging car to burn more oil than the newer ones. Using a high-mileage oil designed to keep the engine parts clean and minimize friction might be the best solution. Its high viscosity provides better protection to the older engines.

Your car’s suspension system did a great job of keeping your rides smooth and car under control. But because of its heavy-duty, the shocks will eventually wear out. Signs of suspension damage include rough car rides, dipping or nose diving when the car stops, damaged, oily shocks, taking turns with pulling or drifting, and uneven tire treads.

If you notice something wrong with your car’s suspension, get it repaired immediately so you can avoid worse issues along the way. Never try to drive when your car’s suspension is worn out.

Fuel systems

The fuel system is responsible for producing energy for the vehicle. Take care of its fuel pump the most. When it fails, it can cause huge drivability issues in your car. You know when your car’s fuel pump is damaged when you struggle to make it start, there is a decrease in the vehicle’s acceleration, fuel efficiency, and power, and it’s making a whirring or whining noise in the backseat.

Worse yet, if your car’s engine has already died or you experience power loss, you have to replace your fuel pump with a new one. The best way to correct a genuinely faulty fuel pump is to replace them, not repair it.

Noises, leaks, paint

When cars make noises, it’s only a sign that they have component failures, and with old cars, this isn’t a surprise. Usually, there will be many other parts needing repairs all at once. Fluid leakage is caused by deterioration or corrosion after years’ use. Their paint wears out as well, which can be restored depending on a few factors.

Are you going through any or a mix of these problems? If your car is just three years older or less, you might not have to buy a new one, of course. But if it’s as old as history, you might be needing new.
