SUVs that last forever are at the top of most of our shopping lists. For most of us, value for money comes from buying something and sticking with it until it can no longer move. Models made by Toyota are famously most likely to last a lifetime, but they are not the only ones that know how to build an SUV built for life.

Longevity Isn’t Just A Honda Or Toyota Story

There is no escaping the fact that iSeeCars says the SUV with the highest chance of reaching 250,000 miles is the Toyota Sequoia, with a 39.1 percent chance. They also say that the top four brands with the highest likelihood of reaching 250,000 miles are Toyota, Lexus, Honda, and Acura, with a 17.8 percent, 12.8 percent, 10.8 percent, and 7.2 percent chance, respectively.

GMC And Chevrolet Beat The Average Lifespan Rate By Nearly Double

American SUVs don’t always get the same reputation for longevity as their Japanese rivals, but the numbers show that some are more than capable of sticking around. Several full-size American SUVs rank well for their chances of reaching 250,000 miles, with the GMC Yukon XL having a nine percent chance, while the GMC Yukon and Chevrolet Tahoe come in at 7.8 percent and 7.7 percent, respectively.

This is still well above the 4.3 percent average for SUVs, and it shows that a big American SUV doesn’t necessarily mean a short ownership life. For the most part, they are built around heavy-duty foundations, large engines, and drivetrains designed for a hard life, whether that means hauling a family or towing things behind them.

The Chevrolet Suburban Is One Of The Longest-Lasting Three-Row SUVs

As a permanent fixture of the American SUV market, the Chevrolet Suburban has earned the respect of millions of drivers thanks to what it offers: lots of space, comfortable cabins, strong engines, and, most importantly here, a long shelf-life.

The 2026 Chevrolet Suburban has a starting MSRP of $63,700, and comes with three rows and seating for up to nine people. Just shy of $64,000 may sound like a lot of money for an SUV, but if you only have to pay that once, it is a good deal.

It Ranks Third For Average Potential Lifespan Among SUVs

iSeeCars says there are seven three-row SUVs in the top 10 most likely to reach 250,000 miles (SUVs only): the Sequoia, the 4Runner, the Highlander Hybrid, the Lexus GX, the Honda Pilot, Highlander, and the Suburban. iSeeCars estimates that a Suburban has an 11.8 percent chance of reaching 250,000 miles, or a 2.8-times better chance than average.

That makes it the eighth most likely among all SUVs to see the big numbers. However, with an estimated average lifespan of 180,512 miles, or around 10 years, and a potential lifespan of 265,732 miles, it comes in third under the Sequoia (296,509 miles) and the Land Cruiser (280,236 miles). These are estimates and not ceilings; the highest-mileage Suburban was a ’94 model which put over one million miles on the clock. But raw lifespan stats only tell part of the story — what makes the Suburban structurally capable of those numbers is a construction philosophy that hasn’t changed since 1935.

Beefy Engine And Body-On-Frame Mean A Proven Foundation

The Suburban didn’t quietly become the longest-lasting GM SUV by accident; it has followed the same sort of overbuilt and sturdy construction that has come to epitomize the typical long-living vehicle. The Suburban is currently in its 12th generation, and like it did back in 1935, it still has a body-on-frame construction. That means it is built to take a hit. The chassis is made out of high-strength hydroformed steel and is durable, suited for heavy-duty tasks, and more resistant to twist than a unibody.

A top contender for the most reliable Suburban engine is the 5.3-liter LM7 Vortec V8 used between ’99 and ’06. It has a cast iron block, no cylinder deactivation, a large displacement, a high torque output of up to 335 pound-feet at 4,000 rpm, and has been well-tested in millions of GM trucks and SUVs during the GMT800 era. With proper maintenance, 300,000 to 400,000 miles is frequent.

The 2026 Chevy Suburban engine choices may not be the LM7, but they have all the right aspects to make them long lifers. The base engine is a 5.3-liter EcoTec3 small-block V8 good for 355 horsepower at 5,600 rpm and 383 pound-feet at 4,100 rpm. The high-performance option is a 6.2-liter EcoTec3 V8 good for 420 horsepower at 5,600 rpm and 460 pound-feet at 4,100 rpm.

Neither gas engine works near its limits, and both have heavy-duty oiling systems that keep them well lubricated when you are working them. However, the smaller option is generally seen as the more reliable, as it is lower-stress.

The 2026 Suburban is also available with a 3.0-liter Duramax LZ0 diesel inline-six. This lump is good for 305 horsepower at 3,750 rpm, and more importantly, 495 pound-feet of torque at a very low 2,750 rpm. It has forged steel pistons, a forged steel crankshaft, and a very rigid bottom end. Low-stress and torquey, it is an engine made for a long life with proper maintenance.

The Suburban’s Size Is A Big Part Of Its Family Appeal

It’s all well and good to say a vehicle can last hundreds of thousands of miles, but it wouldn’t be much good unless it were usable and nice to be in every day for those thousands of miles. Technically, a bicycle can last a million miles if you look after it. This year’s Suburban seems to be very well received, with owners who left a review on Kelley Blue Book rating it 4.2 out of 5 overall, 4.1 out of 5 for value, 4.2 out of 5 for quality and reliability, 4.4 out of 5 for performance, 4.7 out of 5 for styling, and 4.8 out of 5 for comfort.

Enough Interior Room That Your Family Will Never Outgrow It

True to its lineage, the Suburban is no small machine; the 2026 model measures 226.3 inches in length by 81 inches in width, and rides on a 134.1-inch wheelbase. That may make it tricky for some to drive, but it does open up a huge amount of room inside. There is seating for up to nine people, if you opt for the three-seat front row, and all rows get a good deal of seating space.

Up front, you get 42.3 inches of headroom and 44.5 inches of legroom; the second row has 38.9 inches of headroom and 42 inches of legroom; the third row has 38.2 inches of headroom and a very respectable 36.7 inches of legroom. It is also equipped to carry a lot of stuff around with you. With all the seats in place, there is 41.5 cubic feet of storage space. With the third row folded away, that grows to 93.8 cubic feet, and with both rear rows folded away, you get a massive 144.5 cubic feet.

Towing Ability Adds Versatility Beyond Everyday Duty

A family that outgrows sedans often also outgrows a weekend with just a tent — and the Suburban is built for the camper, the boat, and the trailer that come with that stage of life. If that wasn’t enough, with the 5.3-liter V8 equipped, you can tow up to 8,200 pounds. With the 6.2-liter V8 equipped, you get a tow rating of up to 8,000 pounds, and 8,100 pounds with the turbo-diesel, the same.

To hit the peak numbers, you do need to add the Max Trailer Package, which adds a better fan, an integrated trailer brake controller, and a hitch guidance camera, but if you are looking to go further afield with the family, trailers and boats are not out of the question.

The Suburban Makes A Strong Case For Long-Term Ownership

There are some downsides to buying a new Suburban. Firstly, the six trims of the new Suburban are not cheap. Before any extras or adding four-wheel drive or a different engine, the LS costs $63,700, the LT costs $66,700, the Z71 costs $73,700, the RST costs $71,700, the Premier $78,600, and the High Country $83,700.

Then there are fuel costs. FuelEconomy.gov says the most efficient models are two-wheel-drive, Duramax-equipped models, which can achieve 23 combined mpg (21 mpg city/26 mpg highway), costing you $3,450 a year for fuel. The least efficient are four-wheel-drive models with the 6.2-liter V8, which can achieve just 16 combined mpg (14 mpg city/18 mpg highway), and will cost you an estimated $4,750 a year for gas.

However, you are well covered for tech and comfort features, which include a standard 17.7-inch touchscreen and 11-inch driver gauge, wireless Apple CarPlay and Android Auto, HD Surround Vision, rear parking sensors, wireless charging, available leather upholstery, available heated seats, an available 15-inch HUD in the High Country, and available ventilated front seats.

Of course, one day, these things will go out of date, as tech from only a few years ago has. However, what won’t go out of date are the rock-hard build and family-friendliness that have made the Suburban such a respected American SUV. The Chevy Suburban’s real appeal is not about being the newest or easiest to park; it is about giving enough room for family life, enough comfort for long trips across the country, enough muscle, and enough mechanical substance to stay useful once the novelty wears off and the miles rack up.
