5.0/10
2 walk-away risks, 6 serious faults, 1 minor fault documented for this generation, weighted by severity and repair cost. Biggest factor: 9-speed harsh shifting and 2023 sun-gear recall. Score methodology.
The 2017-2023 Acadia is more manageable than the old Lambda Acadia, but it has one very GM-specific used-car filter: prove the shifter, transmission and recall history before judging the leather. The expensive traps are 2017-2019 Shift-to-Park failures, 2019-2023 9-speed shift or sun-gear recall exposure, 2017-2018 right-front driveshaft separation recall, 2020 fuel-pump burr recall, 2021 fuel-line recall, 2022 fuel-tank rollover-valve recall, and 2023 half-shaft/windshield recalls. The safest buy is a 2021-2022 3.6 with closed fuel/camera/suspension recalls, no park-message history and clean 9-speed behavior. Current owners should keep shifter, fuel-system and driveline campaign paperwork because future buyers will know these issues.

Best years
2021-2022
Best buys
- 2021-2022 3.6 AWD with recall closures, matched tires, no Shift-to-Park history and smooth 9-speed behavior.
- 2020 3.6 after fuel-pump and airbag/tire recalls are closed.
- 2020-2023 2.0 turbo only for light use with clean boost/cooling records.
Inspect hard
- 2017-2018 launch cars for Shift-to-Park, right-front driveshaft recall, brake caliper recall and HPFP recall.
- 2019-2023 9-speed cars for hard shifts, delayed engagement and transmission campaign status.
- 2022-2023 AWD cars for fuel tank, suspension toe link, half-shaft and windshield campaign records.
Avoid
- Acadia that will not power down cleanly because the shifter still reports not in Park.
- 3.6/9-speed with flare, harsh engagement, P0741/P0776/P0796 or no TCM scan allowed.
- Open fuel-line, fuel-tank, driveshaft or half-shaft recall on a vehicle being sold as ready.
Next checks
Before you contact the seller
Check the car's history first. Then bring the right tools if it still looks worth viewing.
Primary next step
Check history, title, and recall status
The faults above matter more if the car also has accident history, finance flags, missing service records, or open safety recalls.

Engines and trims
Which GMC Acadia should you buy?
On most used cars, the engine and trim choice changes the risk more than the mileage does. Narrow this down before you start viewing cars.
2.5L LCV four-cylinder
2017-2020
BASIC, ONLY IF CHEAP
The 2.5 keeps purchase price low but feels strained in a family crossover. It avoids some V6 expense, yet the same shifter, recall and age checks still apply.
3.6L LGX V6
2017-2023
BEST NORMAL ENGINE
The V6 suits the Acadia best. Pre-2020 cars use the 6-speed, while later cars move into the 9-speed era, so the inspection focus changes from launch recalls to shift quality and campaign status.
2.0L LSY turbo four-cylinder
2020-2023
GOOD IF NOT WORKED HARD
The 2.0T is efficient and modern, but it is less desirable for heavy passenger/tow use. Check cooling, boost behavior, fuel quality history and the 9-speed before paying V6 money.
Year notes
Year-by-year buyer advice
Use this to narrow the search before you spend time travelling to view a car.
2017
Second generation launched; old Acadia Limited also existed separately.
Buyer: High complaint year; check shifter, driveshaft, brake caliper and HPFP campaign status.
Owner: Treat park-message and brake/fuel recall paperwork as core records.
2018
Carryover with right-front driveshaft and HPFP recall exposure.
Buyer: Acceptable only after VIN recall closure and clean shifter test.
Owner: Any front clunk or fuel smell should be matched against recalls first.
2019
Last pre-facelift year; Shift-to-Park remains common.
Buyer: A clean 2019 can work, but repeated shifter repairs are a warning.
Owner: Keep the latest shifter repair invoice.
2020
Facelift, 2.0T option and 9-speed automatic; fuel-pump recall affects selected VINs.
Buyer: Check 9-speed behavior and fuel-pump recall closure.
Owner: Service transmission fluid conservatively if towing or urban driving.
2021
Fuel-line and surround-camera recall populations affect some vehicles.
