For drivers who want to keep their vehicles for the long haul, choosing a reliable SUV is more than brand loyalty—it's a commitment to value, efficiency, and peace of mind. Some sport utility vehicles stand out above the rest, not just for their initial build quality but for their legendary longevity, proven through decades of owner reports and real-world performance. Whether you need a family hauler, adventure machine, or daily commuter, these five SUVs are trusted favorites that routinely reach—and even exceed—the 400,000-mile mark when well maintained. Here’s what makes each so enduring.

Toyota Land Cruiser: The Unrivaled Longevity Legend

No list of high-mileage SUVs is complete without mentioning the Toyota Land Cruiser, a name synonymous with dependability and durability worldwide. Originally developed for military and expedition use, the Land Cruiser’s engineering is built for harsh environments and constant abuse—from the deserts of Australia to the snowfields of Alaska. Its proven body-on-frame construction, robust naturally aspirated engines, and conservative, overbuilt drivetrain components are made to outlast even the most punishing conditions.
Owners routinely report minimal major repairs over hundreds of thousands of miles. Many '90s and early 2000s Land Cruisers have clocked beyond 400,000 or even 500,000 miles with just regular fluid changes, routine maintenance, and attention to rust prevention. Toyota’s global parts supply ensures everything remains serviceable well into old age. Though the new Land Cruiser is more upscale and rarer in the U.S., the used market and global support make it one of the longest-lasting SUVs on Earth—a testament to simple design and relentless reliability.

Honda Pilot: Proven Family Workhorse Across Generations

Since its debut, the Honda Pilot has balanced car-like ride quality with genuine toughness—a favorite for families, rideshare drivers, and long-distance commuters. Available with bulletproof V6 engines and a transmission lineup that’s seen solid improvements in recent generations, the Pilot’s track record for longevity is stellar. Owners frequently report crossing the 300,000-mile mark with minimal issues, and well-maintained older Pilots—especially those with manual transmissions or after transmission improvements in the late 2000s—are known to hit 400,000 miles and keep going strong.

Honda’s attention to well-engineered basics—timing belts, hydraulic engine mounts, transmission cooling, and rustproofing—reduces the potential for catastrophic failures. High parts availability and a strong owner community make major repairs affordable if they do arise. Versatile interiors, flat load floors, and multiple seating configurations mean comfort doesn’t fade as the odometer rises. Regular timing belt changes, fluid flushes, and replacing wear items like bushings will keep your Pilot running for decades. For those seeking an SUV that doubles as a lasting family companion, the Pilot is tough to beat.

Toyota 4Runner: Rugged Simplicity That Lasts

With a devoted fanbase and nearly four decades of continuous refinement, the Toyota 4Runner’s reputation for high mileage is well earned. This body-on-frame SUV shines off-road but delivers equal poise on pavement, thanks to a reliable lineup of naturally aspirated V6 and, in earlier models, bulletproof inline-four engines.
What sets the 4Runner apart is its simplicity: the suspension, drivetrain, and transmission systems are designed for ease of maintenance and durability over the long haul. Older models still on original drivetrains are not uncommon, and many 4Runners are found with 400,000 or even 500,000 miles—especially in dry climates where rust isn’t an issue. Its robust transfer case, solid rear axle, and reputation for withstanding hard use make it a go-to for anyone planning to keep a vehicle for life. Aftermarket support is among the best, with a wealth of replacement parts, upgrades, and knowledgeable mechanics across the U.S.

Lexus GX & LX: Luxury Meets Lifelong Service

Toyota’s luxury division, Lexus, offers two SUVs—the GX and LX—that leverage the proven mechanical foundations of the Land Cruiser Prado and Land Cruiser 200. Owners of the GX (especially the GX 470 and GX 460) and LX 570 regularly log high mileages, thanks to trustworthy V8s, reliably shifting automatics, and overbuilt suspensions.

Even as luxury features like air suspension, adaptive cruise, and heated/ventilated seats were introduced, Lexus maintained a focus on using the highest-grade materials inside and out. With annual maintenance, these SUVs shoulder decades of use. Electrical systems, leather upholstery, and advanced tech features have all shown solid longevity in consumer reports. The LX in particular shares most of its running gear with the global Land Cruiser, so parts compatibility and service expertise are unrivaled, enabling mileages rivaling 400,000 miles and more for dedicated owners determined to keep luxury running long term.

Ford Expedition: American Full-Size Durability

For those needing full-size capability, the Ford Expedition has proven itself a stalwart of the high-mileage club. Modern Expeditions, especially those from the third and fourth generations, utilize sturdy body-on-frame construction, beefy EcoBoost V6s, and 10-speed automatics that resist the pitfalls of older Ford transmissions. Their spacious interiors, user-friendly electronics, and confidence-inspiring towing ratings (often above 9,000 pounds) make them a mainstay for families and outdoor enthusiasts.

Fleet and livery drivers praise the Expedition for its longevity in commercial use, often driving well beyond 300,000 miles with only routine maintenance, timely turbo servicing, and diligent attention to cooling systems. The Expedition’s widespread popularity ensures strong aftermarket support and parts availability—which translates to a lower cost of ownership over time. Regular oil changes, preventive gearbox flushes, and periodic suspension work are generally all it takes to push the Expedition into the 400,000-mile club.

Conclusion

Longevity in SUVs isn’t just about picking a famous badge—it’s about proven, robust engineering, regular maintenance, and a tradition of quality. The Toyota Land Cruiser, Honda Pilot, Toyota 4Runner, Lexus GX/LX, and Ford Expedition each earn their place among the vehicles most likely to see 400,000 miles (and beyond) thanks to their rugged backgrounds, owner communities, parts availability, and bulletproof drivetrains. For retirees, families, outdoor adventurers, or anyone seeking a “forever” SUV, these models offer true peace of mind and value, letting you enjoy the open road for decades to come.
