One SUV has an eight-times-average shot at reaching 250,000 miles, a new study finds

Most vehicles are retired well before their odometers approach a quarter million miles, but a small number are built to go the distance. A study of longevity across the vehicle market found that one full-size sport-utility vehicle, the Toyota Sequoia, has roughly eight times the average chance of reaching 250,000 miles, making it a standout for buyers who plan to keep a vehicle for the long haul.

The Sequoia’s standout longevity odds

The research, conducted by the automotive data firm iSeeCars, estimated each model’s likelihood of surviving to 250,000 miles. The Sequoia posted about a 39 percent chance of reaching that threshold, compared with an average of roughly 4.8 percent across all vehicles studied. That places its odds near eight times the typical figure.

An estimate in that range means that a large share of Sequoias on the road can be expected to accumulate very high mileage, whereas most vehicles fall far short. The gap between the leader and the average illustrates how unevenly durability is distributed across the market.

Reaching 250,000 miles is a demanding benchmark. It represents years of use for most drivers, and only a handful of models clear it at anything close to the rate the Sequoia does, which is what makes its result notable.

How the longevity study works

The analysis drew on data from a large pool of used vehicles to see how many of each model were still on the road at high mileage. By comparing the share of each model that reached 250,000 miles, the study produced a ranking of which vehicles are most likely to last.

Such a method reflects real-world outcomes rather than laboratory predictions, capturing the combined effect of engineering, build quality, and how owners tend to treat a given model. It measures survival in actual use, which is what matters to a buyer weighing long-term ownership.

Because the ranking is based on how vehicles actually fare over time, it rewards models that hold up under the wear of daily driving rather than those that merely look durable on paper. The resulting odds are a practical guide grounded in observed behavior.

Why full-size SUVs tend to endure

Large sport-utility vehicles like the Sequoia are often built on rugged, truck-derived platforms designed to handle heavy loads and towing. Components engineered for that kind of duty can experience less relative stress in everyday driving, which can translate into a longer service life.

Powertrains in these vehicles are frequently tuned for durability rather than peak performance, and their generously sized engines and transmissions may operate well within their limits during normal use. That built-in margin is one reason body-on-frame SUVs recur near the top of longevity rankings.

The same qualities that make these vehicles heavy and thirsty can also make them tough. Engineering aimed at hauling and towing tends to favor sturdy, over-built components, and those components often keep working long after lighter parts would wear out.

Brand history plays a part as well. The Sequoia comes from a lineup with a longstanding reputation for reliability, and models built by manufacturers with a track record of durable engines and transmissions tend to appear near the top of longevity studies again and again. That consistency suggests the result reflects deliberate design priorities rather than chance.

Simplicity can be an asset too. Vehicles that avoid the most complex or unproven technology sometimes age better, because there are fewer intricate systems to fail as the miles accumulate. A rugged, conventional design can prove more forgiving over a long service life than a more elaborate one.

The role of maintenance

No vehicle reaches extreme mileage on durability alone. Consistent maintenance, including timely oil and fluid changes and prompt attention to worn parts, is essential to realizing a model’s potential lifespan. A durable design rewards careful upkeep and can be undone by neglect.

The study’s odds describe the fleet as a whole, blending well-maintained vehicles with poorly kept ones. An individual owner who follows the recommended service schedule can improve the chances that a specific vehicle lands on the high-mileage end of the range.

What the numbers mean for buyers

For shoppers focused on long-term value, a model with strong longevity odds can be a sound choice, since a vehicle that lasts longer spreads its purchase cost over more years and miles. High expected lifespan can also support stronger resale values, because used buyers pay attention to reliability reputations.

The findings reinforce a familiar pattern in which certain brands and body styles repeatedly top durability rankings. For a buyer prioritizing the ability to reach very high mileage, a proven long-lasting SUV offers a measurable statistical edge over the average vehicle on the road, turning what might feel like a gamble into an informed choice.
