How much does the 2024 GMC Sierra 1500 cost?

Prices have softened 10.69% compared to this time last year, making it a favorable time to shop this model year.

Is the 2024 GMC Sierra 1500 a good car?

Yes — the 2024 GMC Sierra 1500 earns a 4.64/5 user rating and a 7.17/10 expert rating. The model scores 8/10 across Performance, Form and function, and Technology.

Owners consistently praise the powerful engine choices, comfortable and spacious interior, and well-equipped features. The design and upscale feel also come through strongly, with many owners appreciating the truck’s styling compared with competitors.

The main trade-offs are concerns around emissions controls and some infotainment reliability complaints, plus the need for a data plan in some use cases. That fits the Sierra’s role as a truck that can serve as a work vehicle, an off-roader, or a long-distance cruiser, depending on how you configure it.

Good and great deals account for 33.8% of listings, which gives you a decent chance of finding a competitive price.

Is the 2024 GMC Sierra 1500 reliable?

Owners rate it 4.64/5, a strong signal of long-term satisfaction.

The owner feedback points to a truck that feels powerful, comfortable, and well equipped over time, with several mentions of design appeal and luxury touches that hold up in daily use. That same feedback also suggests you should pay attention to infotainment behavior and emissions-related concerns when evaluating a used example.

The expert evaluation also describes the diesel powertrain as smooth, linear, and well suited to towing without hurting everyday drivability. Warranty coverage includes a three-year, 36,000-mile bumper-to-bumper warranty and a five-year, 100,000-mile powertrain warranty, which helps reduce early ownership risk.

For used buyers, the biggest long-term risk is buying a truck with unresolved electronics or powertrain-related issues, so a careful pre-purchase inspection matters.

What should I look for when buying a used 2024 GMC Sierra 1500?

Accident-free inventory is excellent at 93.2% — clean inventory, standard diligence applies.

You should still run a vehicle history report and prioritize a thorough inspection, especially if you’re shopping higher-mileage trucks or examples with more complex equipment. Focus on how the truck was used, whether the infotainment system behaves properly, and whether the condition matches the trim level and equipment you expect.

Key things to evaluate:

• Trim level: The lineup ranges from Pro to Denali Ultimate, with the base Pro aimed at commercial fleets and the higher trims adding more luxury and off-road focus. The Pro is notably basic, while Denali and Denali Ultimate bring upscale touches such as a large chrome grille, available 22-inch wheels, and power running boards.
• Powertrain: You can find a 2.7-liter TurboMax four-cylinder, 5.3-liter V8, 6.2-liter V8, and Duramax 3.0-liter turbodiesel. The diesel stands out for strong torque and efficiency, while the V8s add more power and the TurboMax serves as the entry engine.
• Safety package: Standard equipment includes automatic emergency braking with pedestrian detection, forward collision warning, lane-keep assist, lane-departure warning, and a rear-seat reminder. Adaptive cruise control, blind-spot monitoring, rear cross-traffic alert, park assist, and Super Cruise are optional or trim-dependent.
• Infotainment: Base Pro models use a 7-inch touchscreen with Bluetooth and wired Apple CarPlay and Android Auto. SLE and higher trims get a 12.3-inch digital instrument cluster, a 13.4-inch touchscreen, wireless Apple CarPlay and Android Auto, and Google Built-In.
• Fuel efficiency: The Duramax diesel is EPA-rated at 25 mpg combined with RWD and 24 mpg combined with 4WD. The TurboMax can reach 20 mpg combined in some configurations, while the V8s return a few mpg less.

Which 2024 GMC Sierra 1500 trim should I buy?

The 2024 GMC Sierra 1500 is offered in 8 trim levels: Pro, SLE, Elevation, SLT, AT4, AT4X, Denali, and Denali Ultimate.

Here's the short version:

• Pro: This is the fleet-focused starting point, and it makes sense only if you want the lowest entry price and can live with the most basic equipment. It gets a 7-inch touchscreen with Bluetooth and wired smartphone connectivity, but it lacks the richer cabin and tech upgrades found higher up the range.
• SLE: This is the first trim that feels like a mainstream retail choice because it adds the larger digital instrument cluster, the 13.4-inch touchscreen, wireless smartphone integration, and Google Built-In. It’s the best-value trim for most shoppers who want modern tech without jumping into luxury pricing.
• Elevation: This trim builds on the SLE formula with a more style-forward presentation, making it a good fit if you want a cleaner, more upscale look without going all the way to the premium trims.
• SLT: This is the step-up choice for buyers who want more comfort and a more premium feel while staying below the luxury-focused models. It suits shoppers who want a better-equipped daily driver and are willing to pay for it.
• AT4: This is the off-road-oriented choice, with a 2-inch lift kit, Rancho monotube shocks, a locking rear differential, and skid plates. It’s the right pick if you want trail capability and the Duramax diesel as standard.
• AT4X: This is the more serious off-road version, adding a front locker and more sophisticated Multimatic DSSV dampers. It’s for buyers who want the most capable dirt-focused Sierra short of the AEV Edition.
• Denali: This is the luxury trim that leans into chrome, comfort, and upscale presentation. It’s the right choice if you want a premium-feeling truck with available Super Cruise.
• Denali Ultimate: This is the top luxury trim and the best fit if you want the most feature-rich Sierra 1500. It layers on the highest-end comfort and tech content, including the kind of amenities that make the truck feel closest to a luxury vehicle.

Super Cruise is available on Denali and Denali Ultimate, while the off-road hardware is concentrated in AT4, AT4X, and AT4X AEV Edition variants.

Is now a good time to buy a used 2024 GMC Sierra 1500?

The market looks moderately favorable if you’re selective and willing to compare listings carefully.

• Deal availability: 33.8% of listings are priced as good or great deals.
• Inventory: There are 9,685 listings available.
• Price trend: Prices have softened 10.69% compared with last year.
• Clean inventory: 93.2% of listings are accident-free.

If you find a listing below $48,427, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2024 GMC Sierra 1500's resale value?

The current average of $48,427 sits slightly below last year's $54,226.

That decline suggests the market has already adjusted downward, which can help you as a buyer but may pressure resale if you plan to sell soon. If you buy at the right price now, you reduce the chance of taking a steep depreciation hit later.

Higher-trim trucks with desirable equipment may hold attention better than basic examples, especially if they’re clean and well maintained. Strong condition and the right powertrain mix matter a lot in a segment where shoppers compare features closely.

Vehicles with strong owner satisfaction ratings, like this model year's 4.64/5, tend to retain buyer demand, which supports resale value over time.

Is the 2024 GMC Sierra 1500 safe?

The 2024 GMC Sierra 1500 earns Good IIHS results in the driver-side small overlap front test, the original moderate overlap front test, and the original side crash test, but it also earns an Acceptable result in the updated side crash test and a Marginal result in the passenger-side small overlap front test. It earns five-star ratings in overall NHTSA testing and side-crash protection, and four-star ratings in frontal crash and rollover.

It earns a 6/10 safety score from our experts.

Standard safety equipment includes automatic emergency braking with pedestrian detection, forward collision warning, lane-keep assist, lane-departure warning, and a rear-seat reminder. Adaptive cruise control, blind-spot monitoring, rear cross-traffic alert, park assist, and GM’s Safety Alert driver’s seat are optional, and Super Cruise is available on Denali and Denali Ultimate.

The mixed IIHS results are the main caution here, especially the passenger-side small overlap score and the updated side-crash result. If safety is a top priority, you should pay close attention to which driver-assistance features are actually fitted on the truck you’re considering.

Should I buy a 2024 GMC Sierra 1500 or consider a different year?

If you're weighing the 2024 against nearby model years, here's how to think about it:

Choose the 2024 if:

• 33.8% of listings are priced as good or great deals.
• Accident-free inventory is excellent at 93.2% — clean inventory, standard diligence applies.
• Price trend: Prices have softened 10.69% compared with last year.
• Owners rate it 4.64/5 — a strong satisfaction signal.
• The 2024 model keeps the Sierra’s broad trim and powertrain range while adding a diesel that’s standard on AT4 and AT4X.

Consider the 2023 if:

• At $45,237, the 2023 costs less than the current year's $48,427 average.
• It emphasizes upscale luxury and practical cabin space.

The bottom line: If you want the newer model-year pricing context, stronger inventory, and the 2024-specific equipment mix, the 2024 is the better default choice. If your priority is saving money up front, the 2023 is the more budget-friendly path and still delivers the Sierra’s core luxury-truck appeal.
