Our five-year ownership calculator puts the 2024 Lexus GX at $50,603 total, or $843 a month on average. That figure assumes 12,000 miles per year at typical used-car pricing, and it includes everything: depreciation, fuel, repairs, maintenance, insurance, and registration. For context, that monthly number is close to what some people pay for rent. So the question worth asking before you fall in love with the GX's interior is simple: what exactly are you paying for?
The answer is more interesting than you might expect, and not entirely flattering.
The 2024 GX is a body-on-frame SUV. That means it sits on a truck chassis, not a car platform. Most luxury SUVs today, from the BMW X5 to the Audi Q7, use car-based platforms that ride more smoothly, handle better, and get better fuel economy. Lexus went the other direction with the GX.
This generation was redesigned for 2024, and it is genuinely capable off-road. It has a proper multi-link rear suspension, a two-speed transfer case for serious four-wheel-drive work, and available locking differentials. If you plan to leave the pavement, that matters.
But if you live in the suburbs and your idea of off-roading is a wet parking lot, you are paying for hardware you will never use, while giving up ride comfort and fuel economy that a Mercedes GLE or Genesis GV80 would hand you for similar money.
The GX is genuinely for people who want Land Cruiser-level trail capability with a Lexus interior. It is not for people who just want a big, prestigious SUV for school drop-off.
Lexus offers the GX in four trims. You can build your own at the Lexus configurator.
| Trim | MSRP | What You Actually Get |
|---|---|---|
| Premium | $62,000 | 14-inch touchscreen, 21-speaker Mark Levinson audio, leather seats, dual-zone climate, 18-inch wheels |
| Premium+ | $67,500 | Adds head-up display, 360-degree camera, power-folding third row, panoramic roof |
| Luxury | $73,500 | Semi-aniline leather, 20-inch wheels, rear-seat entertainment, ventilated front seats |
| Overtrail | $76,000 | Off-road focus: locking rear differential, skid plates, all-terrain tires, raised suspension |
The Premium is the entry point and already well-equipped. The Overtrail is the one to take seriously if you actually go off-road. The Luxury trim adds comfort features but loses some of the rugged identity that makes the GX interesting in the first place.
Here is where the five-year math gets uncomfortable. Our calculator shows $18,624 in fuel costs over five years. That is the single largest cost category in the ownership estimate, bigger than depreciation.
The 2024 GX is powered by a 3.4-liter twin-turbocharged V6 making 349 horsepower. On paper, that sounds modern and efficient. In practice, fueleconomy.gov rates it at 17 mpg city, 22 mpg highway, 19 mpg combined for two-wheel-drive models. Four-wheel-drive versions drop slightly. For a $65,000-plus vehicle in 2024, that is difficult to defend.
A BMW X5 xDrive40i gets 21 combined. A Genesis GV80 3.5T gets 21 combined. Neither of those is impressive either, but the GX trails both. If you drive 15,000 miles a year and gas averages $3.50, you are spending roughly $2,760 annually just on fuel. Over five years, that adds up to a number that should give any buyer pause.
Step inside, and the case for the GX gets stronger. The 2024 redesign brought a genuinely premium interior that does not feel like it was assembled by accountants. The 14-inch touchscreen is large and responsive. The Mark Levinson sound system, standard across trims, is excellent. Physical controls for climate are still present, which sounds like a small thing until you spend time in cars where they are not.
Third-row seating is available, though honest: adults back there will be uncomfortable on trips longer than 20 minutes. It is functional for kids or short hauls.
The ride quality is better than previous GX generations, which set a low bar, but still falls short of car-platform competitors. On the highway, you feel the truck underneath you. Some buyers consider that a feature. Most will not.
Lexus reliability is the quiet reason many people pay the premium. The brand consistently scores near the top of long-term reliability surveys. Our five-year repair estimate of $3,402 reflects that: low for a vehicle in this segment and price range. Maintenance over five years comes in at $4,977, also reasonable given what you are driving.
At $62,000 to $76,000, a few things should not be optional or absent.
There is no plug-in hybrid option. No mild hybrid. No electrification at all. In a segment where the Land Rover Defender offers a PHEV and the Mercedes GLE offers a 48-volt mild hybrid, Lexus is asking you to pay luxury prices for a powertrain strategy from 2018.
The third-row seat feels like an afterthought. Other full-size luxury SUVs, like the Lincoln Navigator or Cadillac Escalade, actually seat three adults in the back. The GX does not clear that bar.
Android Auto is available, but wireless CarPlay and Android Auto are not on base trims. At this price, that is a small but telling detail about where Lexus sets its priorities.
As of this writing, the 2024 GX has not received a full NHTSA five-star rating or an IIHS Top Safety Pick designation. The vehicle is too new for complete testing results. Check nhtsa.gov and iihs.org directly before purchase, especially if safety ratings are a deciding factor for your family.
Lexus Safety System+ 3.0 is standard across all trims, which includes pre-collision warning with pedestrian and cyclist detection, adaptive cruise control, lane departure alert, and automatic high beams. The technology is solid. The crash-test results simply are not in yet.
If you buy a new GX Premium at roughly $62,000, here is a realistic first-year picture.
New vehicles lose between 15 and 22 percent of their value in year one. On a $62,000 GX, that is $9,300 to $13,640 in depreciation in twelve months. Call it $11,000 as a midpoint estimate. That is money that does not come back.
At 15,000 miles and $3.50 per gallon with 19 mpg combined, fuel runs approximately $2,763.
Insurance for a luxury SUV in this class typically runs $1,200 to $1,800 per year, depending on your location, driving history, and coverage level.
The first service interval on the GX is at 10,000 miles and covers oil, filter, and inspection. Expect to pay $150 to $250 at a Lexus dealer.
Add it up: year one on a new GX Premium will likely cost you somewhere between $15,400 and $18,000 before your car payment.
Land Rover Defender 110: The Defender matches the GX in off-road capability and beats it on visual presence, but Land Rover's long-term reliability record is a real liability. The GX wins on ownership confidence; the Defender wins on character.
BMW X5: The X5 rides better, handles better, and offers plug-in hybrid power that the GX simply cannot match. The GX wins on trail capability and, probably, long-term repair bills; the X5 wins almost everywhere else if pavement is your world.
Toyota Land Cruiser: They share a platform and a corporate family, and the Land Cruiser costs more. The GX wins on value and interior finish at equivalent trim levels; the Land Cruiser wins on brand heritage and, for some buyers, resale cachet.
The five-year total of $50,603 is not outrageous for a luxury SUV. What makes it hard to swallow is that the biggest line item, $18,624 in fuel, reflects a powertrain that has not kept pace with the competition. You are paying for a truck chassis, off-road hardware, and Lexus reliability, and those things have real value. But only if you use them.
Buy the GX if you genuinely go off-road, if you tow, if you want a capable family hauler that will run reliably for 200,000 miles with minimal drama, and if fuel economy is not a primary concern. The Overtrail trim, in particular, is a specific and honest product for a specific and honest buyer.
Skip the GX if you mostly drive on paved roads, if fuel costs matter to you, or if you want the most refined on-road experience your money can buy. At this price, the X5 drives better on the highway. The GV80 has a nicer interior for less money. The GX's strengths are real, but they are pointed in a direction that most luxury SUV buyers will never actually use.
