When it comes to long-term reliability and durability, not all SUVs are created equal. While many vehicles struggle to reach 200,000 miles before requiring major repairs or retirement, a select group of SUVs has earned legendary status for their ability to cross the half-million-mile threshold.
These remarkable vehicles represent the pinnacle of automotive engineering, combining robust construction, dependable powertrains, and thoughtful design that stands the test of time.
The SUVs that achieve 500,000 miles or more share several common characteristics: they’re built on truck-based platforms with body-on-frame construction, feature proven engine and transmission combinations, and benefit from meticulous maintenance by their owners.
Many of these vehicles come from manufacturers with reputations for reliability, though the specific models matter more than the brand name alone.
For budget-conscious buyers, these high-mileage champions represent exceptional value in the used market. While they may cost more upfront than less reliable alternatives, their proven longevity means lower total cost of ownership over time.
Whether you need a vehicle for long commutes, towing heavy loads, or simply want something that will serve your family for decades, these SUVs deliver unmatched durability.
This list examines ten used SUVs with documented cases of surpassing 500,000 miles, exploring what makes them so exceptionally durable and what buyers should know when shopping for these legendary vehicles.
1. Toyota Land Cruiser
The Toyota Land Cruiser stands as perhaps the most legendary SUV ever built when it comes to extreme longevity and reliability. This full-size SUV has been Toyota’s flagship off-road vehicle for over six decades, and its reputation for indestructibility is well-earned.
Land Cruisers routinely surpass 500,000 miles, with many examples documented well beyond 600,000 or even 700,000 miles with proper maintenance.
What makes the Land Cruiser so exceptionally durable starts with its conservative engineering approach. Toyota deliberately over-engineers critical components, using thicker materials and more robust designs than necessary for typical use.
The body-on-frame construction provides a solid foundation that can withstand incredible abuse. Generations from the 1990s through 2000s are particularly prized, with the 100-series (1998-2007) and 200-series (2008-2021) both achieving remarkable longevity records.
The powertrains are legendary for their reliability. The 4.7-liter V8 (2UZ-FE) found in many models is considered one of Toyota’s most bulletproof engines, capable of running for hundreds of thousands of miles with just regular oil changes. The 4.5-liter V8 diesel available in international markets is equally renowned.
These engines feature simple, proven designs without overly complex technologies that can fail over time. The Land Cruiser’s suspension components, drivetrain parts, and chassis are all built to military-grade standards.
This SUV was designed for harsh conditions in developing countries where repairs might be difficult or impossible, so reliability was paramount. The full-time four-wheel-drive system is robust and mechanical, avoiding the electronic complexity that plagues modern SUVs.
Common high-mileage issues are relatively minor: rust on older models, particularly in the frame and body panels; timing belt replacement every 90,000 miles on older engines; and eventual wear on the center differential and transfer case bearings.
However, these are predictable maintenance items rather than catastrophic failures. The interiors hold up remarkably well, with seats and materials that resist wear far better than typical vehicles.
When shopping for a used Land Cruiser, expect to pay premium prices even for high-mileage examples, as their reputation keeps values strong. Look for complete maintenance records, particularly proof of timing belt changes and differential service.
Rust inspection is critical on older models. Despite their cost, Land Cruisers represent one of the safest bets for a vehicle that will genuinely last a lifetime.
2. Toyota Sequoia
The Toyota Sequoia shares much of the Land Cruiser’s DNA but offers similar legendary reliability at a more accessible price point. Built on the same platform as the Tundra pickup truck, the Sequoia has been delivering families exceptional durability since 2001.
First and second-generation Sequoias (2001-2023) regularly achieve 500,000 miles, making them outstanding values in the used SUV market.
The secret to the Sequoia’s longevity lies in its truck-based construction and proven Toyota powertrains. The first-generation models used the bulletproof 4.7-liter V8, the same engine found in the Land Cruiser and Tundra.
Second-generation Sequoias (2008-2023) received the even more powerful 5.7-liter V8 (3UR-FE), which has proven equally reliable in real-world use. Both engines feature timing chains rather than belts, eliminating one major maintenance concern.
The body-on-frame construction provides exceptional structural integrity that holds up over hundreds of thousands of miles. Unlike unibody crossovers that can develop structural flex and rattles, the Sequoia’s separate frame maintains solid construction even after decades of use.
The chassis components are borrowed from heavy-duty truck applications, meaning they’re overbuilt for typical SUV duty. For used buyers, the Sequoia offers Land Cruiser-like reliability at often half the price.
Look for examples with towing packages, as these received upgraded cooling systems and differentials. Maintenance records are valuable, particularly for transmission fluid changes and differential service. Even high-mileage examples with proper care can easily double their odometer readings.
3. Chevrolet Suburban
The Chevrolet Suburban holds the distinction of being the longest-running nameplate in automotive history, and its longevity isn’t just about the badge; these massive SUVs are built to last.
Generations from the 1990s through the present day regularly surpass 500,000 miles, particularly when equipped with the legendary small-block V8 engines that General Motors has perfected over decades.
The Suburban’s secret weapon is its truck DNA. Built on the same platform as GM’s full-size pickups, the Suburban benefits from heavy-duty components designed for commercial and fleet use.
The body-on-frame construction with a fully boxed frame provides exceptional durability. Police departments, fire services, and government agencies have relied on Suburbans for decades precisely because they can withstand extreme use.
The powertrains are a major strength. The Vortec 5.3-liter and 6.0-liter V8 engines found in models from the 2000s and 2010s are incredibly robust, sharing architecture with engines used in commercial trucks.
These engines feature simple pushrod designs without overly complex variable valve timing or direct injection systems (in earlier versions), making them easier to maintain and more reliable long-term.
The 4L60E, 4L80E, and later six-speed automatic transmissions are proven units, though they benefit from regular fluid changes.
When shopping for a used Suburban, prioritize maintenance records and avoid examples used for heavy towing without proper service.
The 2007-2014 models represent a sweet spot of proven reliability with some modern amenities, while 2015+ models offer better fuel economy and updated interiors while maintaining core durability.
4. GMC Yukon/Yukon XL
The GMC Yukon is essentially a badge-engineered Chevrolet Suburban and Tahoe, but it deserves its own mention because the GMC brand often attracts more meticulous owners who maintain their vehicles religiously.
The Yukon and extended-length Yukon XL share all the mechanical durability of their Chevrolet siblings while often commanding slightly higher resale values due to GMC’s positioning as a more premium brand.
Like the Suburban, the Yukon is built on GM’s full-size truck platform with body-on-frame construction. This means it benefits from the same robust engineering, proven powertrains, and heavy-duty components.
The Vortec and later EcoTec3 V8 engines provide hundreds of thousands of miles of reliable service when properly maintained. The four-wheel-drive systems are mechanical and straightforward, avoiding the electronic complexity of some modern systems.
What sets the Yukon apart in the used market is often the buyer demographic. GMC markets itself toward professional buyers who tend to keep detailed service records and perform recommended maintenance.
This means finding a well-maintained high-mileage Yukon is often easier than finding equivalent Chevrolet models. The Denali trim level, while more expensive, often comes with features like the more robust 6.2-liter V8 and upgraded interior materials.
When shopping for a used Yukon, look for the SLT or Denali trims with the 6.2-liter V8 if you want maximum longevity and don’t mind higher fuel costs.
Verify the service history for the Active Fuel Management system, and consider having it disabled if you plan to keep the vehicle for the ultra-long term. Examples from Texas and the Southwest often have much less rust than Midwest examples.

5. Ford Expedition
The Ford Expedition has long been overshadowed by GM’s full-size SUVs in discussions of durability, but this is largely undeserved. The Expedition, particularly second and third-generation models (2003-2017), has proven highly capable of crossing the 500,000-mile threshold when properly maintained.
Built on Ford’s F-150 platform, these SUVs benefit from truck-grade components and proven powertrains. The key to Expedition longevity is the powertrain selection.
The 5.4-liter Triton V8 found in second-generation models (2003-2006) and early third-generation models (2007-2014) is a workhorse engine that, despite some issues with spark plug design in certain years, delivers exceptional longevity when maintained.
The later 3.5-liter EcoBoost V6 in 2015+ models has also proven durable, though it’s too new to have as many documented ultra-high-mileage examples.
The body-on-frame construction provides the structural integrity necessary for long-term durability. Ford’s fully boxed frame design resists flex and holds up well even in harsh conditions.
The independent rear suspension on 2003+ models provides better ride quality than solid-axle competitors while still proving durable in long-term use. The drivetrain components are borrowed from the F-150, meaning they’re proven in heavy-duty applications.
The Expedition’s depreciation is steeper than GM or Toyota competitors, which makes it an attractive used purchase. A well-maintained example with 150,000-200,000 miles can often be purchased inexpensively, then driven another 300,000+ miles with proper care.
This represents exceptional value for buyers willing to commit to regular maintenance. The 2011-2014 models represent a sweet spot of proven reliability with updated styling and features.
6. Lexus GX 470/GX 460
The Lexus GX brings luxury to ultra-high-mileage SUVs without sacrificing the legendary Toyota reliability. Based on the Toyota Land Cruiser Prado (not sold in the US), the GX shares much of the Land Cruiser’s proven engineering while offering more comfortable accommodations.
Both the GX 470 (2003-2009) and GX 460 (2010-present) routinely achieve 500,000 miles, with many examples documented well beyond.
The GX 470 uses the same bulletproof 4.7-liter V8 found in the Land Cruiser and Sequoia, paired with a five-speed automatic transmission.
This combination is virtually unbreakable with proper maintenance. The GX 460 upgraded to a 4.6-liter V8 with more power and a six-speed automatic, both of which have proven equally reliable. These engines feature timing chains rather than belts, and the internal components are built to incredibly tight tolerances.
What sets the GX apart from its Toyota siblings is the attention to detail in construction and materials. The interior features higher-grade leather, better sound insulation, and more sophisticated technology yet this luxury doesn’t compromise longevity.
Lexus engineers these components to last, using materials that resist wear exceptionally well. Even 300,000-mile examples often have interiors that look remarkably fresh.
The body-on-frame construction and full-time four-wheel-drive system are carried over from Toyota’s truck platforms, providing exceptional durability.
The suspension uses the innovative Kinetic Dynamic Suspension System (KDSS) on many models, which provides excellent off-road capability while maintaining on-road comfort. While more complex than simple suspensions, the KDSS has proven reliable in long-term use.
When shopping for a used GX, look for examples with complete Lexus dealer service records. These vehicles often attract owners who maintain them properly.
The 2010-2013 GX 460 models represent excellent value as early examples of the current generation. Even high-mileage examples can be confidently purchased when maintenance has been performed on schedule.
7. Toyota 4Runner
The Toyota 4Runner has built an almost cult-like following among enthusiasts who value longevity and off-road capability. This mid-size SUV has been using body-on-frame construction and proven Toyota powertrains since its inception, and examples regularly surpass 500,000 miles.
The third-generation (1996-2002), fourth-generation (2003-2009), and fifth-generation (2010-present) models all have documented cases of extreme longevity.
The 4Runner’s durability stems from its conservative engineering and truck-based platform. Fourth-generation models use the legendary 4.7-liter V8 or the reliable 4.0-liter V6, both of which are capable of extreme mileage.
Fifth-generation models standardized on the 4.0-liter V6, which has proven nearly bulletproof. The five-speed automatic transmission is robust, and the four-wheel-drive system is mechanical and straightforward.
What makes the 4Runner particularly special is Toyota’s refusal to chase trends. While competitors moved to unibody crossover construction, the 4Runner retained its truck-based platform.
While others added complex electronics, the 4Runner kept systems simple. This conservative approach means proven components rather than experimental technologies that might fail after warranty expiration.
The suspension design favors durability over cutting-edge comfort. The solid rear axle on most models is nearly indestructible, and replacement parts are affordable and readily available.
Even the independent rear suspension on Sport models holds up well. The chassis components are galvanized and rust-resistant, though earlier models from rust-belt states can still develop corrosion issues.
When shopping for a used 4Runner, prioritize maintenance records and avoid examples used for extreme off-roading without proper service.
The Trail Edition and TRD Off-Road models often come with upgraded components. Examples from dry climates like Arizona or California often have much less rust than those from the Midwest or Northeast.
8. Honda Pilot
The Honda Pilot brings unibody construction to this list of ultra-high-mileage champions, proving that body-on-frame design isn’t the only path to longevity.
First-generation (2003-2008), second-generation (2009-2015), and third-generation (2016-2022) Pilots all have documented cases of surpassing 500,000 miles, making them the most durable crossover-style SUVs available.
The Pilot’s reliability stems from Honda’s reputation for engineering excellence and the use of proven powertrains. The 3.5-liter V6 engine found in all generations is legendary for its durability, featuring Honda’s sophisticated but reliable VTEC variable valve timing.
This engine delivers strong power while maintaining exceptional longevity. The five-speed and six-speed automatic transmissions, when properly maintained, prove equally durable.
Honda’s unibody construction in the Pilot is exceptionally well-executed. The chassis is rigid and well-braced, resisting the flex and rattles that plague lesser vehicles.
The welding quality and structural adhesives are among the best in the industry. This attention to detail in construction pays dividends at high mileage, when cheaper vehicles begin to feel loose and worn.
The Pilot’s all-wheel-drive system on AWD models is sophisticated but has proven reliable in long-term use. The Variable Torque Management (VTM-4) system uses a rear differential with electromagnetic clutches to distribute power, and while more complex than mechanical systems, Honda’s execution has been solid.
Front-wheel-drive models avoid this complexity entirely while still delivering excellent longevity. The Pilot depreciates more than Toyota competitors but holds value better than most crossovers. This creates an opportunity for used buyers to find well-maintained examples at reasonable prices.
A second-generation Pilot (2009-2015) with 150,000 miles can often be purchased affordably and driven another 350,000+ miles with proper maintenance, representing exceptional value. When shopping for a used Pilot, verify the transmission service history above all else proper fluid changes are critical to longevity.
9. Lexus LX 570
The Lexus LX 570 represents the pinnacle of luxury and longevity, combining the Land Cruiser’s legendary durability with Lexus’s commitment to quality and refinement.
Based directly on the Land Cruiser platform, the LX 570 (2008-2021) shares its mechanical foundation while adding luxury features and materials. These SUVs routinely achieve 500,000 miles while providing a premium ownership experience throughout.
The LX 570 uses the same 5.7-liter V8 found in the Tundra and Sequoia, an engine renowned for its reliability and longevity. Paired with a robust six-speed automatic transmission and full-time four-wheel-drive system, the powertrain is virtually bulletproof.
The engine features a timing chain rather than a belt, eliminating one major maintenance concern. Internal components are built to incredibly tight tolerances and designed for extreme longevity.
What distinguishes the LX from the Land Cruiser is the level of luxury and refinement. The interior features premium leather, real wood trim, and sophisticated technology yet all of it is engineered to last.
Lexus doesn’t compromise durability for luxury; instead, they ensure luxury components meet the same longevity standards as mechanical parts. The result is an SUV that feels fresh and premium even at 300,000 miles.
The body-on-frame construction is identical to the Land Cruiser, providing exceptional structural integrity. The chassis components are galvanized and rust-resistant.
The suspension, while tuned for comfort rather than off-road prowess, uses the same robust components as its Toyota sibling. The electronic systems are more sophisticated than the Land Cruiser’s, but Lexus’s conservative approach to technology ensures long-term reliability.
Common high-mileage issues are remarkably minimal. The hydraulic suspension system on some models can develop leaks as it ages, though it’s generally reliable.
The complex climate control system may eventually need attention. The navigation system becomes outdated but continues functioning. The secondary air injection system can fail, triggering a check engine light. These are minor concerns in the context of longevity the major components simply don’t fail.
The LX holds its value extraordinarily well, often depreciating less than any other luxury SUV. Even high-mileage examples command strong prices because buyers understand their longevity.
When shopping for a used LX 570, expect to pay premium prices, but know you’re getting a vehicle that can genuinely last a lifetime with proper care.
10. GMC Yukon Denali XL
While we’ve discussed the GMC Yukon earlier, the Yukon Denali XL deserves special mention as the flagship of GM’s full-size SUV lineup and one of the most reliable luxury SUVs ever built.
The Denali XL combines extended length for maximum interior space, luxury appointments, and the robust mechanical foundation of GM’s truck platform. These SUVs regularly achieve 500,000+ miles while providing a premium ownership experience.
The Denali XL uses the more powerful 6.2-liter V8 engine standard, a significant upgrade from the base 5.3-liter. This engine, also found in high-performance Corvettes and Camaros, proves incredibly durable in SUV applications where it’s never stressed to its limits.
The Active Fuel Management cylinder deactivation system has caused issues in some examples, but many long-term owners have this system disabled. The robust six-speed automatic transmission handles the power easily.
What sets the Denali apart is the attention to detail in construction and materials. The interior features premium leather, real wood and aluminum trim, and sophisticated technology.
Unlike many luxury vehicles where these features become expensive maintenance nightmares, GM engineers the Denali’s luxury components for longevity. The magnetic ride control suspension provides excellent ride quality while proving durable in long-term use.
The extended-length XL configuration provides maximum interior space with third-row seating that’s actually usable for adults. This makes the Denali XL ideal for large families or those who need to transport many passengers regularly.
The additional length doesn’t compromise the truck-based platform’s durability the fully boxed frame provides excellent structural rigidity.
When shopping for a used Denali XL, look for examples with complete service records and verify that all recall work has been completed.
The 2015-2020 models represent the current generation with updated styling and features while maintaining the proven durability of the platform.
