Summary
The GMC Terrain has 17 recalls spanning 2010 through 2022, with the most serious being a fuel pump defect on 2022 models where reduced fuel flow can cause the engine to stall suddenly while driving and may not allow a restart. Staying with the most recent production years, 2021 and 2022 Terrain vehicles equipped with certain Hankook tires can experience tread separation while driving, reducing handling and raising the risk of a crash. There is also a driver seat recall on 2022 models with power seats that lack the memory function, where a loose or stripped height-adjustment bolt can allow the seat to shift in a crash.
On the safety systems side, 2018 models have an airbag control module that can fail to power down correctly when the vehicle is shut off, leaving the airbag system inoperative at the next startup so it cannot detect a crash or deploy the airbags. The 2020 model year has a child seat anchor issue where an overly thick coating on the lower anchor connection bars can prevent a child seat from attaching properly, which can allow it to move in a crash. On 2019 models, the rear-right head restraint bracket can be improperly welded, allowing the restraint to shift during a crash rather than holding the occupant's head in place.
Going back further, the 2014-2015 model years share a wiper module recall where ball joints corrode and can cause one or both wipers to stop working. The same corrosion issue also affects 2013 models. A headlight housing reflection on 2010-2017 vehicles can produce excessive glare above the road, reducing visibility for oncoming drivers. On 2010 models, the integrated center stack software can render the climate controls, defroster, radio, and panel lighting all inoperative at once, and a separate wiper transmission link joint corrosion issue can cause wiper separation. Also on 2010 models, a driver seat height-adjustment bolt can loosen and drop the seat to its lowest position, impairing reach to vehicle controls and forward visibility. A 2016 model year compliance recall covers certain vehicles where the certification label shows incorrect tire and rim size information, which can lead to improperly sized or inflated tires.
