What Is a Reasonable Life Span for a Modern Car?

With modern cars, there’s more to go wrong because you have more systems and technology than previous generations. On the other hand, they’re generally better built because many features are implemented efficiently, such as abilities added via software rather than new mechanical components. Even the metals are more rust-resistant than they were in the past, so corrosion and body integrity are less of an issue nowadays.

Despite their complexity, hybrid powertrains in general have also demonstrated solid reliability. "The Prius has a long-standing history for being reliable and proven to go the distance with proper maintenance," says Veselak.

To choose a car that will last, always avoid buying the first year of a new model. That gives the manufacturer time to work out any kinks that might arise with new technology. By the second or third year, there’s enough real-world data to give you a general idea of its reliability. 

When it comes to a used car, it pays to do the research on that specific model to find out what problems might exist. For example, a 2014 Hyundai Santa Fe Sport might be prone to transmission issues. You’ll want to see maintenance records to know that the car you’re looking at has been properly serviced and the transmission fluid changed. You should also have it inspected by a mechanic before purchasing. 

When it comes to making your car last, here are a few tips to keep it on the road for as long as possible:

Drive your car regularly. It’s a machine, and machines work better when they’re used. Fluids circulate, rubber seals and gaskets expand and contract, and tires won’t develop flat spots when you drive your car on a regular basis. 

Keep up the maintenance. Follow your vehicle’s maintenance intervals, particularly when it comes to oil changes and tuneups. Have your mechanic inspect brakes, tires, filters, and other vital parts annually, and replace them as needed. Many times, car owners will defer maintenance until they have multiple costly repairs, and that can be overwhelming. 

Address problems quickly. As a car ages, it’s bound to develop a few rattles or strange noises. You’re better off having your mechanic inspect them now instead of having them turn into bigger problems later.

Keep your car clean. Over time, salt and road grime will dull paint and contribute to rust on the underbody. Be sure to run your car through a car wash periodically, especially if you live in a snowy region. 

Bottom line: Choose a reliable brand and a proven model, follow maintenance intervals, and treat your car well. The better shape it’s in, the more you’ll appreciate it and be willing to hang on to it longer.
