2020 GMC Acadia test drive
overall

GMC attempts to remove the invisibility cloak wrapped around the 2020 Acadia, a midsize three-row crossover SUV struggling to overcome an identity crisis.
Long story short, as a friend of mine likes to say, GMC screwed up. This is just my opinion, of course, but when GMC redesigned the Acadia for the 2017 model year, the SUV shrank in size and switched to a softer look in order to plug a huge hole in the Buick-GMC SUV lineup.
Fast-forward to 2020, and GMC may have decided this move was a bad idea. As part of a refresh, the new Acadia adopts bolder styling and adds a new AT4 trim level with greater off-roading capability. Additional changes include the availability of a new turbocharged four-cylinder engine, a new nine-speed automatic transmission, and new and updated technology.
These revisions do help the Acadia to better stand out in what is now an ocean of midsize SUVs, from Hyundai to Kia and Honda to Toyota, and everything in between, but it’s up to GMC to make people aware of this fundamentally good, but oh-so-vanilla SUV. And the company must also address the Acadia’s questionable value.

My old vehicle was same make and model just older. Had to stick with the make and model to accommodate my requirements and fit my budget well!! Very happy to find a newer model with similar features. Will miss the DVD system but was rarely used. Grandkids will just have to do without. LOL.

I love my GMC Acadia. This is the second one I’ve owned and probably will not buy anything else. It looks tough yet gets great gas mileage. It is very roomy and is a perfect fit for our family.

On the trade-off side, the expert review points to fairly pedestrian performance and notes that advanced safety features are not standard.
For you, that means the Acadia makes the most sense if you want a comfortable, family-friendly three-row SUV with a polished feel rather than a standout driving personality. The market also shows 26.8% good or great deals, so there are still some attractive opportunities if you shop carefully.
Is the 2020 GMC Acadia reliable?
Owners rate it 4.94/5, a strong signal of long-term satisfaction.
The owner feedback also points to a vehicle that feels dependable, comfortable, and easy to live with over time. Reviewers repeatedly highlight its smooth ride and family-friendly character, which usually matters most when you want a used SUV you can count on day after day.
The expert review reinforces that impression by describing the Acadia as smooth, refined, and agreeable in everyday driving. It also notes that GMC includes a first maintenance visit at no charge, which is a small ownership perk.
For used buyers, the main long-term risk is less about outright durability and more about whether the vehicle’s value and equipment level justify what you pay.
What should I look for when buying a used 2020 GMC Acadia?
At 68.4% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
You should start with a vehicle history report and then prioritize a thorough inspection of bodywork, alignment, and signs of prior repair. Because the Acadia’s value proposition depends heavily on condition and equipment, you’ll want to focus on how well the cabin, technology, and safety features have been maintained. It also makes sense to compare trims carefully, since some important driver-assistance features are not standard on every version.
Key things to evaluate:
- Trim level: The Acadia comes in SL, SLE, SLT, new rugged AT4, and luxurious Denali trim levels. The base setup is more limited on advanced safety equipment, while Denali adds a more upscale cabin with leather upholstery, wood trim, and extra visual polish.
- Powertrain: Lower trims use a 193-horsepower 2.5-liter four-cylinder engine. SLT gets a turbocharged 2.0-liter four-cylinder with 230 hp and 258 pound-feet of torque, while AT4 and Denali use a 310-hp 3.6-liter V6. All three pair with a new nine-speed automatic transmission.
- Safety package: Standard equipment includes blind-spot warning and rear cross-traffic warning, plus rear-seat reminder and Teen Driver technology. Forward collision warning and low-speed automatic emergency braking require SLT or AT4 at minimum, and the broader Driver Alert Package adds lane-departure warning, lane-keeping assistance, pedestrian braking, parking sensors, automatic high-beam headlights, and a head-up display.
- Infotainment: Every Acadia includes Bluetooth, Apple CarPlay, Android Auto, and GMC Connected Services with a 4G LTE WiFi hotspot. Versions with an 8-inch touchscreen get a higher-resolution display, a simplified interface, and improved voice recognition, and the system also adds USB-C ports, an optional wireless charging pad, a high-definition surround-view camera, and a rear camera mirror.
- Fuel efficiency: The test vehicle returned 21 mpg in combined driving, and the review notes that stop/start and cylinder deactivation are used to improve fuel economy.
Which 2020 GMC Acadia trim should I buy?
The 2020 GMC Acadia is offered in 5 trim levels: SL, SLE, SLT, AT4, and Denali.
Here's the short version:
- SL: This is the entry point, so it makes sense if you want the lowest-cost way into the Acadia lineup and are comfortable with a simpler equipment set.
- SLE: This trim is the better starting point for many shoppers because it keeps the Acadia’s core strengths while staying closer to the value end of the range.
- SLT: This is the best-value trim if you want the turbocharged 2.0-liter engine and access to more advanced safety equipment, including the Driver Alert Package content.
- AT4: Choose this if you want the rugged character and the standard dual-clutch AWD system, along with all-terrain tires and the more off-road-oriented setup described in the review.
- Denali: Pick this if you want the most upscale version, with the 310-hp V6, premium cabin touches, and the most exclusive safety content, including the enhanced automatic emergency braking system.
The safety-package gap to keep in mind is that forward collision warning and low-speed automatic emergency braking are not standard on the base Acadia SL.
Is now a good time to buy a used 2020 GMC Acadia?
This is a moderate, selective buyer’s market, so you can shop with some leverage if you focus on condition and price.
- Deal availability: 26.8% of listings are priced as good or great deals.
- Inventory: There are 2,650 listings available.
- Price trend: Prices have softened 10.09% compared with last year.
- Clean inventory: 68.4% of listings are accident-free.
If you find a listing below $20,501.62, that's toward the low end of the year-round range and worth acting on quickly.
What is the 2020 GMC Acadia's resale value?
The current average of $20,499 sits slightly below last year's $22,800.
That price movement suggests the Acadia has already absorbed a meaningful amount of depreciation, which can help future resale stability if you buy at the right price. For you, that means the biggest resale advantage comes from choosing a clean, well-equipped example rather than overpaying for a higher-mileage or accident-history vehicle.
Because the market has softened, a future seller may need to price competitively to move the vehicle. That said, strong condition and desirable equipment should still help it stand out in a crowded segment.
Vehicles with strong owner satisfaction ratings, like this model year's 4.94/5, tend to retain buyer demand, which supports resale value over time.
Is the 2020 GMC Acadia safe?
The Insurance Institute for Highway Safety gives the Acadia high marks in the tests it has completed, and NHTSA gives it five-star ratings in most assessments, plus a four-star rollover resistance rating.
It earns a 6/10 safety score from our experts.
The Acadia comes standard with rear-seat reminder, Teen Driver technology, automatic collision notification, SOS emergency calling, blind-spot warning, and rear cross-traffic warning. If you want forward collision warning and low-speed automatic emergency braking, you need to move up to SLT or AT4 at minimum, and the broader Driver Alert Package adds lane-departure warning, lane-keeping assistance, pedestrian braking, parking sensors, automatic high-beam headlights, and a head-up display.
One important caveat is that advanced safety features are not standard, so you should verify exactly which driver-assistance items are included on any used example you’re considering.
Should I buy a 2020 GMC Acadia or consider a different year?
If you're weighing the 2020 against nearby model years, here's how to think about it:
Choose the 2020 if:
- 26.8% of listings are priced as good or great deals.
- At 68.4% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
- Price trend: Prices have softened 10.09% compared with last year.
- Owners rate it 4.94/5 — a strong satisfaction signal.
- The 2020 refresh adds bolder styling, a new AT4 trim, a turbocharged four-cylinder engine, and updated technology.
Consider the 2019 if:
- At $17,479, the 2019 costs less than the current year's $20,499 average.
- It feels more upscale than many rivals while still delivering solid driving dynamics.
The bottom line: If you want the newer styling, updated tech, and broader trim and powertrain choices, the 2020 is the better all-around pick. If your priority is saving money and you can live without the refresh-era changes, the 2019 is the more budget-friendly path.
