Known issues to check on a 2018 GMC Terrain
- 2018-2020 VIN-Specific Recalls (2018–2020)
Several recalls apply to specific early second-generation Terrains: 18V340 (2018 air bag control module may not power down correctly), 18V358 (2018 high-pressure fuel pump may detach), 18V576 (2018-2019 rear caliper coating), 17V516 (2018 front intermediate driveshaft), and 20V668 (2018-2020 transmission accumulator bolts).
What to do: Run the VIN at NHTSA or GMC and confirm every applicable recall is complete. - Turbo Engine Maintenance (Second and Third Generation) (2018–2026)
Every Terrain since 2018 uses a small turbocharged engine. Turbo engines depend on on-time oil changes with the correct oil; owners have reported coolant loss and turbo-related codes on some 1.5L engines.
What to do: Review oil-change records and check fluid levels before buying. - 1.6L Turbodiesel Emissions System (2018-2019) (2018–2019)
The rare 2018-2019 Terrain diesel uses diesel exhaust fluid (DEF) and a particulate filter. Short-trip driving can clog the filter, and DEF system faults can limit power.
What to do: On a diesel, scan for emissions codes and confirm DEF and filter service history. - 9-Speed Automatic and Push-Button Shifter Check (2018–2024)
Some 2018-2024 owners report rough or delayed shifts from the 9-speed automatic and occasional shifter or park-engagement messages with the push-button selector. Software updates address some cases.
What to do: Drive in traffic and test the shifter; ask whether transmission updates were applied. - Terrain Generation, Engine and Transmission Disambiguation (2011–2026)
The Terrain has three generations in this range: 2011-2017 (2.4L four, 3.0L V6 through 2012, 3.6L V6 from 2013, 6-speed), 2018-2024 (1.5L turbo, 2.0L turbo through 2020, 1.6L diesel 2018-2019, 9-speed), and 2025-on (1.5L turbo with a CVT on FWD or 8-speed with AWD). The Chevrolet Equinox is its close relative.
What to do: Confirm the generation, engine, transmission and drivetrain before comparing prices.
Recall applicability varies by model year, production date, engine, transmission, equipment, and VIN. Check the VIN for current open recalls and completed remedies. For first-generation 2.4L models, also ask a GMC dealer about oil-consumption special coverage.
