Modern cars have much longer life spans than one may expect. Not too long ago, drivers often commemorated the milestone of their vehicles reaching the 100,000-mile mark. However, data from Car and Driver indicates the average vehicle now lasts around 12 years or roughly 200,000 miles. More advanced electric or hybrid vehicles may be able to go even farther, with some capable of reaching as many as 300,000 miles.

Thanks to advancements in technology, cars are more durable than ever, but that doesn't make them immune from breakdowns or the need for repairs. A report from AAA found that more than two-thirds of service calls were for vehicles a decade or older. Here's a look at some of the problems that can affect older vehicles.

Among the problems older vehicles face are battery issues. The average car battery lasts between three and five years, according to Auto Zone. Batteries tend to show signs of wear at the four-year mark on average. Corrosion or dirt on battery terminals also can affect battery performance.

Older cars may also experience electrical system problems, caused by anything from burnt-out car fuses to bad or faulty electrical connections and contacts. Corroded or loose screws, nuts and wires can cause electrical issues, which may be more common in older vehicles that have significant mileage on them.

Vehicles may also have trouble with their suspension system, which consists of springs, tires, shock absorbers, struts, anti-sway bars and other parts that connect the vehicle to the wheels. Suspension systems regulate the amount of bouncing in the vehicle while on the road and make it manageable. Eventually, all suspension systems wear out, and parts need to be serviced or replaced.

Evaporative emissions are another challenge. The evaporative system consists of a network of hoses, canisters and valves, and it helps vent pressure in the gas tank. An older vehicle may end up with a cracked hose that can cause a fuel leak. Hoses also may be compromised elsewhere in vehicles, so these points should be checked during routine maintenance.

As with other moving parts on a car, the brake system wears down over time, and parts need to be replaced. Squealing, squeaking or a soft brake pedal are indicative of braking system issues and should be looked at by a mechanic promptly.

Modern vehicles are increasingly being controlled by computers. These computers handle a variety of features, including navigation and pairing to mobile phones, among others. Over time, systems may no longer work if there are no computer updates available. That means Bluetooth pairing may no longer function, or maps may not be current for GPS systems.

Due to technological advancements, cars and trucks have longer life spans than they used to. However, age is still a factor in the deterioration of vehicle systems.
