overall

Summary
With 9,711 currently listed for sale and an average price of $45,263, 32.9% of 2023 GMC Sierras for sale on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2023 GMC Sierra 1500 4.33 / 5 stars and CarGurus experts gave it a 7.83 / 10.
92.2% of 2023 Sierra 1500 models on CarGurus are accident free.
Why it stands out
The 2023 GMC Sierra 1500 stands out by pushing full-size pickup luxury further than the brand’s familiar Denali formula. GMC says the new Denali Ultimate trim ups the ante for pickup-truck luxury, and the truck’s high-end positioning is reinforced by the idea that nearly every luxury-car feature has now found its way into premium pickups. That makes the Sierra 1500 appealing to buyers who want a truck that feels more upscale and feature-rich than the traditional work-focused formula.
It also has practical strengths that help it feel more than just a luxury showcase. The Sierra 1500 is praised for tons of cabin space, a lively diesel engine, and versatile features. At the same time, it is not without drawbacks: the truck can feel like it has too much tech for a truck, its cabin quality still trails the competition, and city parking can be a challenge without tech aids.

The review summary also points to a strong mix of options and an improved interior compared with older models. On the downside, some owners mention rising prices, limited availability of certain features, and concerns about engine problems for long-term ownership.
That lines up with the truck’s positioning in the overview: you’re looking at a full-size pickup that leans hard into upscale features and luxury-truck appeal, especially if you want something more premium than a traditional work truck. The market also shows 33.6% good or great deals, which is a decent sign that you can still find value if you shop carefully.
Is the 2023 GMC Sierra 1500 reliable?
Owners rate it 4.33/5, a solid signal of long-term satisfaction.
The owner feedback also points to a truck that many drivers find dependable enough to recommend, with praise centered on comfort, technology, and overall satisfaction. The expert drive notes reinforce that impression by describing the diesel powertrain as lively and the truck as smooth and composed in daily use. The powertrain warranty is five-year/60,000-mile, which adds some peace of mind for used buyers.
Still, the long-term ownership risk is worth watching closely because some owners mention engine concerns, so a careful history check matters.
What should I look for when buying a used 2023 GMC Sierra 1500?
Accident-free inventory is excellent at 92.1% — clean inventory, standard diligence applies.
You should still run a vehicle history report and prioritize a pre-purchase inspection, especially if you’re considering a higher-mileage truck or one with more complex equipment. Focus on condition, maintenance records, and whether the features you want actually work as intended. If you’re shopping a luxury-leaning trim, make sure the added tech and convenience items have been properly cared for.
Key things to evaluate:
- Trim level: The base Pro keeps things simpler with a 7-inch touchscreen, cloth seats, Bluetooth, and a more straightforward cabin layout, while higher trims add more luxury and convenience. The SLE brings heated front seats, a heated steering wheel, a larger touchscreen, and a digital instrument panel, while the Denali Ultimate adds nearly every feature optional on other trims.
- Powertrain: You can choose from a 2.7-liter turbocharged four-cylinder, a 3.0-liter Duramax turbocharged inline-six diesel, a 5.3-liter V8, or a 6.2-liter V8. The diesel is the efficiency standout, while the V8s and turbo-four cover the rest of the lineup.
- Safety package: Standard equipment includes forward collision warning, automatic emergency braking, pedestrian detection, lane-departure warning, and Teen Driver. Higher trims add blind-spot monitoring, rear cross-traffic alert, front and rear parking sensors, adaptive cruise control, a surround-view camera system, Safety Alert seat, and Super Cruise.
- Infotainment: The base Pro uses a 7-inch touchscreen with Apple CarPlay and Android Auto. Other trims get a 13.4-inch touchscreen with wireless Apple CarPlay and Android Auto, plus Google-connected apps and a more advanced interface.
- Fuel efficiency: The Duramax turbodiesel with RWD returns 24 mpg city, 29 mpg highway, and 26 mpg combined. With 4WD, it returns 22 mpg city, 27 mpg highway, and 24 mpg combined. The turbo-four returns 19 mpg city, 22 mpg highway, and 20 mpg combined, while the 5.3-liter V8 returns 16 mpg city, 21 mpg highway, and 18 mpg combined.
Which 2023 GMC Sierra 1500 trim should I buy?
The 2023 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 simplest choice if you want the Sierra’s core capability without the extra tech-heavy cabin. It keeps the 7-inch touchscreen and a more traditional setup, which may suit you if you prefer a straightforward truck.
- SLE: This is the best-value trim for many shoppers because it adds heated front seats, a heated steering wheel, dual-zone climate control, a digital instrument panel, a larger touchscreen, wireless smartphone integration, and a Wi-Fi hotspot.
- Elevation: This trim builds on the SLE and opens up more options and packages, so it makes sense if you want a more customized truck without jumping straight to the pricier luxury trims.
- SLT: This is the step up if you want a more upscale cabin, with leather upholstery, a power-adjustable front passenger seat, memory settings, and an auto-dimming rearview mirror.
- AT4: Choose this if you want the off-road-oriented setup, including standard 4WD, skid plates, a lifted suspension, a two-speed transfer case, and an upgraded air filter.
- AT4X: This is the most trail-focused trim, with steel bumpers, an integrated front winch, mud-terrain tires, additional skid plates, upgraded dampers, and front-and-rear locking differentials.
- Denali: This is the luxury play if you want premium styling, Bose audio, ventilated front seats, wireless charging, and a camera view of the truck bed.
- Denali Ultimate: This is the top luxury trim and the one to buy if you want the most equipment, including massaging front seats, 22-inch wheels, a 12-speaker Bose system, and the integrated Kicker sound system in the Multi-Pro tailgate.
The safety package starts with standard driver aids, but the most advanced features are reserved for higher trims, with Denali Ultimate getting the full suite.
Is now a good time to buy a used 2023 GMC Sierra 1500?
This is a moderate market, so you can buy now if the right truck shows up, but you should still compare listings carefully.
- Deal availability: 33.6% of listings are priced as good or great deals.
- Inventory: There are 9,727 listings available.
- Price trend: Prices have softened 9.71% compared with last year.
- Clean inventory: 92.1% of listings are accident-free.
If you find a listing below $45,237, that's toward the low end of the year-round range and worth acting on quickly.
What is the 2023 GMC Sierra 1500's resale value?
The current average of $45,237 sits slightly below last year's $50,100.
That decline suggests the market has cooled, which can help you as a buyer today but may pressure resale if you plan to sell soon. For a future seller, the key takeaway is that pricing has already adjusted downward, so holding value will depend more on condition, mileage, and trim desirability than on broad market momentum. Higher-spec trucks with strong equipment and clean histories should remain easier to move than plain, heavily used examples.
Vehicles with solid owner satisfaction ratings, like this model year's 4.33/5, tend to retain buyer demand, which supports resale value over time.
Is the 2023 GMC Sierra 1500 safe?
The 2023 GMC Sierra 1500 earns Top Safety Pick+ recognition from IIHS and five-star ratings from NHTSA.
It earns a 9/10 safety score from our experts.
Standard safety equipment includes forward collision warning, automatic emergency braking, pedestrian detection, lane-departure warning, and Teen Driver. Higher trims add blind-spot monitoring, rear cross-traffic alert, front and rear parking sensors, adaptive cruise control, a surround-view camera system, Safety Alert seat, and Super Cruise. If you want the most advanced driver assistance, you’ll need to shop higher trims, since the full suite is not standard across the lineup.
Should I buy a 2023 GMC Sierra 1500 or consider a different year?
If you're weighing the 2023 against nearby model years, here's how to think about it:
Choose the 2023 if:
- 33.6% of listings are priced as good or great deals.
- Accident-free inventory is excellent at 92.1% — clean inventory, standard diligence applies.
- Price trend: Prices have softened 9.71% compared with last year.
- Owners rate it 4.33/5 — a solid satisfaction signal.
- It adds the Denali Ultimate luxury focus and broad powertrain choice.
Consider the 2022 if:
- At $42,152, the 2022 costs less than the current year's $45,237 average.
- It brought a major redesign with more lavish tech and new high-end trims.
Consider the 2024 if:
- At $48,427, the 2024 costs more than the current year's $45,237 average.
- It leans harder into versatility with broad work, off-road, and luxury appeal.
The bottom line: If you want the best mix of current pricing, strong inventory, and upscale features, the 2023 is the sweet spot. If your priority is saving money, the 2022 is the better value path. If you want to spend more for a newer model-year alternative, the 2024 is worth comparing, but you’ll pay a premium for it.
