The most reliable new full-size SUVs in 2025

Full-size SUVs remain a staple for families, road-trippers, and anyone needing a spacious, capable vehicle. But with an average price of over $80,000, choosing the right SUV is more important than ever.

According to a new study by iSeeCars, which analyzed prices and life expectancy of over 3.8 million new vehicles, some large SUVs offer significantly better long-term value than others. By comparing the purchase price to the expected lifespan, the study highlights the models that provide the most reliable years on the road for the least amount of money. Here’s what they found.

1. Buick Enclave

The Buick Enclave tops the list as the most reliable full-size SUV for the money, with an average price of $53,448 and an expected lifespan of 9.6 years. That translates to an annual cost of ownership of $5,555—well below the segment average of $7,888 per year. While it may not have the ruggedness of body-on-frame competitors, the Enclave’s refined ride and comfortable interior make it a solid choice for families prioritizing space and value.

2. Nissan Armada

The Nissan Armada is a strong contender in the reliability rankings, with an average purchase price of $65,654 and a lifespan of 10.2 years. This brings its cost per year to $6,408, making it one of the better values among large, truck-based SUVs. Known for its power engine, spacious cabin, and towing capability, the Armada appeals to buyers who need durability without stretching their budget too far.

3. Lexus LX 600

The Lexus LX 600 stands out with the longest expected lifespan of any full-size SUV in the study, clocking in at an impressive 16.4 years. That longevity helps offset its steep average price of $113,104, bringing its cost per year to $6,887—still below the segment average. Built on the same platform as the legendary Toyota Land Cruiser, the LX 600 combines luxury with serious off-road capability, making it a top pick for buyers who want a vehicle that will last well over a decade.

4. Chevrolet Tahoe

The Chevrolet Tahoe remains a go-to option for those seeking a reliable, full-size SUV. With a price of $73,574 and an expected lifespan of 10.5 years, the Tahoe’s cost per year comes out to $7,037. While that’s slightly higher than the top-ranked models, it’s still a solid figure for a vehicle known for its durability, strong resale value, and ability to handle everything from daily commutes to heavy towing.

5. GMC Yukon

Closely related to the Tahoe, the GMC Yukon offers similar reliability with an average lifespan of 10.9 years. However, with a higher price tag of $83,509, its annual cost of ownership rises to $7,645—just under the segment average. Buyers looking for a slightly more upscale experience than the Tahoe will find the Yukon an appealing option, but they’ll pay a premium for it.

Final thoughts

For buyers looking to maximize their investment in a full-size SUV, the Buick Enclave, Nissan Armada, and Lexus LX 600 offer the best balance of affordability and long-term dependability.

While vehicles like the Tahoe and Yukon remain strong choices, their higher annual costs make them slightly less attractive from a value standpoint. With full-size SUVs being some of the most expensive vehicles on the market, understanding which models will last the longest while costing the least over time can make all the difference in finding the best deal.
