2018 GMC Canyon problems: engine and transmission complaints and recalls
76% of relevant owner complaints filed with NHTSA on the 2018 GMC Canyon are about the engine, transmission or fuel system. Well over half of everything owners reported is the drivetrain. That is a severe model-level pattern; every model year we track at this level has a documented failure behind it.
Worse than 96% of the 1,790 model years we track (2010–2023).
Excludes 6 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 67%).
Does the 2018 GMC Canyon have transmission problems?
Owner complaints say yes, heavily, as a model-year pattern. 35 of 46 relevant complaints filed with NHTSA about the 2018 GMC Canyon concern the engine, transmission or fuel system (76%), and the largest group is filed under power train (27). For comparison, the 2017 scores 54%. On a test drive, check for shuddering, slipping, delayed or harsh shifts, or a whine at speed. This describes the model year, not any one car: a well-maintained or already-repaired example can be fine, and a clean model year can still have a bad car in it.

Yes. NHTSA lists 1 recall campaign on the 2018 GMC Canyon involving the engine, transmission or fuel system, out of 1 in total. A recall is the manufacturer admitting a defect and paying to fix it; whether a specific car still has one open depends on its VIN, which the full report checks.
