Buyers shopping for a full-size SUV that will last well past 200,000 miles face a simple but high-stakes question: which models actually survive that long, and how reliable is the evidence behind the rankings? The 2025 iSeeCars study puts the Toyota Sequoia at the top of the list, projecting a 39.1 percent chance the truck will reach 250,000 miles. That figure dwarfs the 4.8 percent average across all vehicles in the study. Toyota also claims the top spot as a brand overall, reinforcing a pattern that has held for several study cycles. Yet the data pipeline behind those numbers, built largely on state title records and odometer readings, carries blind spots that deserve a closer look before anyone treats the rankings as settled science.
Why Sequoia’s 39.1 percent probability stands out in 2025
The gap between the Sequoia and the field is not marginal. A predicted probability of 39.1 percent means the model is roughly eight times more likely to hit 250,000 miles than the average vehicle, according to the longevity research from iSeeCars. That spread matters more than it did five years ago. Average new-vehicle transaction prices have pushed past $48,000, and loan terms routinely stretch beyond six years. When monthly payments run that long, the cost of replacing a vehicle early compounds quickly. A full-size SUV that reliably reaches a quarter-million miles can save its owner thousands in depreciation and financing charges compared with a competitor that fades at 150,000.
The Sequoia’s position also reflects Toyota’s broader engineering philosophy. The brand leads all manufacturers in the share of vehicles predicted to clear 250,000 miles, a ranking that draws on millions of used-car listings and title-transfer records. The Sequoia shares its body-on-frame platform and powertrain lineage with the Toyota Tundra and Land Cruiser, both of which appear regularly in high-mileage rankings. That mechanical overlap gives buyers a secondary data point: if the drivetrain architecture proves durable across multiple nameplates, the longevity signal is harder to dismiss as a statistical fluke.
At the model level, the Sequoia’s track record in the used market reinforces its projected durability. iSeeCars’ profile of the SUV’s long-term reliability notes that owners often accumulate higher-than-average annual mileage during the first decade, suggesting the vehicle is frequently used for towing, road trips, and family hauling rather than light-duty commuting. A truck that sees that kind of use and still populates the high-mileage end of the odometer curve sends a stronger durability signal than one that reaches 250,000 miles only in low-stress service.
How iSeeCars builds its probability estimates
The study’s methodology centers on a predicted probability model rather than a simple count of surviving vehicles. iSeeCars analyzes used-car listings and pairs them with odometer data captured during state title transfers. From that dataset, the firm calculates the likelihood that a given model will still be on the road at specific mileage thresholds. Instead of waiting decades to tally actual 250,000-mile survivors, the model extrapolates from current age and mileage patterns across hundreds of thousands of vehicles.
In practice, that means the Sequoia’s 39.1 percent figure is derived from observed mileage distributions for existing vehicles, adjusted for age and usage. The method attempts to control for the fact that newer generations have not yet had time to accumulate extreme mileage. By estimating survival curves, iSeeCars can compare a ten-year-old Sequoia with a ten-year-old competitor and project which fleet is more likely to cross the 250,000-mile threshold as those vehicles age.
The odometer readings that feed these models originate from a patchwork of state motor vehicle agencies. The National Highway Traffic Safety Administration has documented how those readings are captured and transmitted through title and registration systems, including the role of vehicle history providers that aggregate the data. Through its public safety databases, NHTSA makes extensive information available on recalls, complaints, and crash investigations, but it does not publish a dedicated, model-by-model longevity registry. In the absence of such a federal benchmark, private firms like iSeeCars have stepped in to interpret mileage and registration records.
This distinction is not academic. If the underlying odometer data varies in quality from state to state, the predicted probabilities could shift depending on where the sampled vehicles were titled. States that require electronic odometer disclosure at every title transfer produce cleaner records than states that still allow paper-based reporting or exempt older vehicles from disclosure requirements. Title brands for salvage or rebuilt vehicles can also complicate mileage histories. The hypothesis that stricter odometer-verification rules would narrow the gap between Toyota and non-Toyota survival rates has not been tested publicly. No published study breaks the iSeeCars results down by state-level title policies, and NHTSA’s fraud analyses provide national incidence rates without model-specific detail for full-size SUVs.
Gaps in the data that buyers should weigh
Three open questions limit how far anyone can push these rankings. First, the iSeeCars study does not release the raw title or registration records behind its probability model. Independent researchers cannot replicate the Sequoia’s 39.1 percent figure without access to the same dataset, so the results function as a black box. That does not mean the estimates are wrong, but it does mean they cannot be independently audited in the way academic studies or government statistics often are.
Second, federal safety reporting does not directly answer the longevity question. NHTSA’s portals track complaints, defect investigations, and recall campaigns, but a model with few safety defects is not automatically one that reaches high mileage. A vehicle can be structurally sound yet retire early because of high maintenance costs, poor fuel economy, or shifting owner preferences. Conversely, some models with frequent minor repairs may still accumulate very high mileage when owners decide the underlying platform is worth maintaining.
Third, the study’s probability metric is a prediction, not a census. It estimates the share of a model’s fleet that will reach 250,000 miles based on observed mileage trajectories, but it cannot account for future changes in parts supply, fuel costs, or repair economics that might alter owner decisions. For example, if a critical component becomes scarce or expensive, owners may scrap vehicles earlier than the historical data would suggest. Similarly, shifts in fuel prices or emissions rules could change how long large SUVs remain attractive to second and third owners.
Competing full-size SUVs from General Motors and Ford also appear in various longevity discussions, yet none matched the Sequoia’s predicted probability in the 2025 iSeeCars ranking. That does not mean those trucks are short-lived; many individual examples will cross 200,000 miles. But on a fleetwide basis, the data currently available points to a meaningful edge for Toyota’s entry, at least under the assumptions baked into the probability model.
How shoppers can use – and not overuse – the rankings
For buyers, the key is to treat the Sequoia’s 39.1 percent probability as a strong piece of evidence, not a guarantee. The study offers a valuable, data-driven way to compare models, especially when combined with information on recalls, crash performance, and owner satisfaction. A high predicted survival rate suggests that, on average, a model’s owners are keeping it on the road longer and investing in maintenance rather than walking away when repair bills arrive.
At the same time, the limitations of the data argue against using a single ranking as the sole basis for a purchase. Individual vehicles can deviate widely from the statistical norm depending on maintenance history, driving conditions, and accident exposure. A carefully serviced competitor SUV with detailed records may be a better bet than a neglected Sequoia with gaps in its documentation, even if the model-level probabilities favor Toyota.
The most practical approach is to let the iSeeCars probabilities narrow the field, then apply traditional due diligence. That means prioritizing pre-purchase inspections, verifying service records, checking for open recalls, and considering total cost of ownership, including fuel and insurance. Buyers who need a full-size SUV and plan to keep it for a decade or more can reasonably treat the Sequoia’s ranking as a tiebreaker in its favor, while still recognizing that long-term reliability remains a blend of engineering, data, and the day-to-day choices of each owner.
