Americans are keeping their cars for 13 years — a record high

The average age of cars on American roads has hit a record high of 13 years, as rising new-vehicle prices and high financing costs push more consumers to hold on to what they have rather than trade up.

The shift — from buying new to repairing old — is reshaping the US auto market, creating headwinds for automakers while opening a wide new opportunity for parts suppliers and repair shops.

According to the Nikkei, the average age of passenger cars and light trucks on US roads reached 13 years at the start of this year, an all-time high. The figure has climbed consistently from 12.6 years in 2024 and 12.8 years last year.

The primary reason American vehicles are aging is straightforward: consumers are simply keeping their cars longer instead of replacing them.

New-vehicle prices have risen sharply in recent years, and auto loan interest rates have climbed alongside them, making the cost of switching to a new car increasingly burdensome. Improvements in vehicle durability have also extended how long cars can reliably stay on the road, further lengthening replacement cycles.

The graying of America's vehicle fleet has been a long-running trend. The average age stood at 10.4 years in 2008, then rose to 11.4 years in 2014, 12.1 years in 2021 and 12.6 years in 2024 — an increase of nearly three years over roughly two decades.

Passenger cars are aging particularly fast. Analysis based on US transportation statistics estimates the average age of passenger cars this year at about 14.1 years. As SUVs and pickup trucks account for a growing share of new-vehicle sales, older sedans are staying on the road relatively longer.

As vehicles age, American spending on cars is shifting away from new purchases and toward repairs and parts replacement.

The auto industry typically considers vehicles between six and 14 years old the aftermarket "sweet spot" — the age range when demand for parts and maintenance picks up most sharply. More than 110 million vehicles on US roads today fall into that bracket, accounting for about 38 percent of the total fleet. That share is projected to rise to around 40 percent by 2028.

Older vehicles demand more attention. Engines, electrical systems and cooling components all become more repair-prone with age. Data from the US Bureau of Labor Statistics on consumer spending confirms that owners of vehicles between 11 and 15 years old spend relatively more on engine tune-ups and electrical, exhaust and cooling system repairs. Spending on parts, equipment and accessories also tends to rise as vehicles get older.

For automakers, the trend is unwelcome. Every additional year a consumer holds on to an existing vehicle is another year of deferred demand for a new one.

For parts suppliers and repair shops, however, it is an opportunity. Unlike new-car sales, the US auto aftermarket is structurally geared to benefit from an aging fleet — the older the vehicle, the more parts need replacing and the more repairs are needed.

The shift in American consumer preferences from sedans toward larger vehicles such as SUVs and pickup trucks is also a tailwind for the aftermarket, since larger vehicles generally cost more to maintain than smaller ones.

That said, older is not always better for parts suppliers. When a vehicle becomes too old, consumers are more likely to scrap it than spend heavily on repairs, and the wide variety of parts required across different aging models complicates inventory management.

America's 13-year-old car is more than a measure of vehicle longevity — it reflects a broader shift in household spending. Faced with high new-car prices and steep financing costs, consumers are increasingly choosing to extend the life of what they already own rather than replace it with something new.

In a market long driven by new-car sales, the question is no longer just who can sell the most new vehicles — it is also who can keep the 13-year-old cars already on the road running longest.
