Durability in a family hauler is hard to judge from a showroom, so mileage studies and engine track records offer a better guide. The list below blends lifespan estimates with the odds of reaching a quarter-million miles, plus two Jeeps known for long-lived sixes. Here are twelve SUVs with the strongest proof of going the distance.

1. Toyota Sequoia: Mileage Champion
Toyota’s full-size SUV tops the iSeeCars lifespan study with a potential lifespan of 296,509 miles, the best of any SUV measured. The same company’s 2026 analysis adds a 42.3% chance of the Sequoia reaching 250,000 miles.
That pairing of a high ceiling and strong odds explains the top spot. A potential lifespan is a statistical estimate across many vehicles, so any single truck still depends on maintenance and use, but few rivals start from a better baseline. Shoppers who value resale and low long-term risk often start their search here, which keeps used prices firm.
2. Chevrolet Suburban: Third on the Table
Chevrolet’s biggest wagon posts a potential lifespan of 265,732 miles in the iSeeCars lifespan data, which places the Suburban third among all SUVs.
A podium finish in a study built on high-mileage records suggests real staying power for a vehicle often used for towing and long family trips. Used shoppers should still weigh service history, since a group estimate cannot promise how one example was treated. Its size and cargo room make it a favorite for large households, and the durability data adds a practical argument for keeping one longer.
3. Ford Expedition: Ford’s Lone Entry
Reaching a potential lifespan of 244,682 miles, the Expedition is the only Ford among the 20 longest-lived SUVs in the iSeeCars ranking.
A single appearance still says something, because it shows the model holds its own in a category known for hard use. The gap to the Sequoia is wide, so buyers prioritizing sheer longevity may see it as a solid pick rather than the outright leader. That makes it a sensible alternative for buyers who want a large SUV from an American brand without sacrificing the chance of a long life.
4. Nissan Armada: Armada Holds On
Nissan’s large SUV lands 15th among SUVs with a potential lifespan of 220,172 miles, according to the iSeeCars lifespan study.
A mid-table placement in a field of this size is still respectable, since the figure sits well above what many drivers expect to see on an odometer. The Armada trails the leaders by tens of thousands of miles, so it suits owners who want durability without chasing the very top. Buyers should compare it against cheaper used options, but the number supports the idea that this big Nissan can handle years of family use.
5. Toyota 4Runner: Odds Beat the Average
In September 2026 data reported by the AutoGuide report, the 4Runner has a 33.1% chance of lasting 250,000 miles. That is 6.9 times the 4.8% average for SUVs.
The comparison shows how rare the milestone is for most models and how much a durable design changes the odds. Even with a one-in-three chance, the figure is a probability rather than a guarantee, and regular maintenance remains the biggest factor owners control. Longevity like this helps explain why used examples hold value and why many owners keep them well beyond a typical trade-in cycle.
6. Lexus RX: Hybrid Staying Power
The Lexus RX hybrid carries a 28.9% chance of lasting 250,000 miles, or 6.1 times the SUV average, based on the iSeeCars figures summarized by the AutoGuide report.
A luxury crossover leading on durability runs against the idea that comfort and complexity shorten a vehicle’s life. The result is specific to the hybrid version, so buyers comparing trims should not assume every RX configuration shares the same odds. Resale values for the model tend to reflect that reputation, so a clean maintenance record is worth paying for on the used market.
7. Lexus GX: Rugged and Durable
The Lexus GX shows a 23.3% chance of lasting 250,000 miles, which is 4.9 times the SUV average, in the AutoGuide summary of iSeeCars data.
Few luxury SUVs combine off-road capability with that kind of long-term odds, so the GX appeals to owners who plan to keep a vehicle for many years. A figure near one in four is strong against the average, though it still leaves meaningful room for early retirement. Its odds also mean owners can reasonably plan around a very long ownership period instead of replacing the vehicle after a few years.
8. Toyota Highlander Hybrid: Family Hybrid Pick
Hybrid versions of the Highlander have a 20.7% chance of reaching 250,000 miles, or 4.3 times the SUV average, per the AutoGuide report on iSeeCars findings.
For a three-row family vehicle, those odds suggest the hybrid system is not a durability handicap. Buyers weighing fuel savings against long-term risk can read the result as reassurance, although battery and drivetrain upkeep still deserve attention as mileage builds. Pairing economy with longevity is rare, and it gives families a rare chance to save on fuel while still planning for a long ownership period.
9. Honda HR-V: Small SUV Standout
Honda’s HR-V has a 17.6% chance of reaching 250,000 miles and is the only small SUV in the top 10, according to the iSeeCars longest-lasting study.
Subcompact crossovers rarely appear in durability conversations, which makes this placement notable. The odds trail the larger Toyota and Lexus models, but they offer a reasonable argument for buyers who want a compact footprint without giving up the prospect of a long ownership run. That makes it the budget-minded and city-friendly pick on the list, since most other entries are far larger and pricier to own.
10. Mercedes-Benz G-Class: European Exception
The G-Class carries a 17.3% chance of reaching 250,000 miles, and the iSeeCars study calls it the only European SUV in its top 10.
The boxy Mercedes-Benz stands out because the list is otherwise dominated by other brands. That result does not erase concerns about repair costs in the luxury segment, but it shows that this design can deliver mileage when it is looked after. It also pairs a strong reputation for toughness with a price that most buyers will find well out of reach, so the list value is mostly aspirational.
11. Jeep Wrangler: Legendary Inline-Six
The old 4.0-liter inline-six used in the Wrangler is credited with running anywhere from 300,000 to 500,000 miles, according to a SlashGear engine roundup.
Engine longevity of that scale is the reason older Jeeps keep a loyal following. The range is wide because outcomes depend on upkeep, driving conditions and luck, so the numbers describe what the motor can do rather than a promise for every example. Interest in older Wranglers continues for that reason, and clean examples with the straight-six often draw more attention from enthusiasts than newer models.
12. Jeep Grand Cherokee: Six Built to Last
SlashGear places the Grand Cherokee’s 4.0-liter six among the ten most reliable gas engines ever built, good for 200,000 to 300,000-plus miles.
Sharing its engine with the Wrangler gives the Grand Cherokee a durable foundation, and the ranking supports its place on this list. As with any older vehicle, surrounding parts such as electronics and suspension may wear out well before the engine does. Enthusiasts value this generation for that reason, and well-kept examples remain on the road long after similar SUVs from the same era were scrapped.
