2021 Buick Encore problems: engine and transmission complaints and recalls
61% of relevant owner complaints filed with NHTSA on the 2021 Buick Encore 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 82% of the 1,790 model years we track (2010–2023).
Excludes 3 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 58%).
Does the 2021 Buick Encore have engine problems?
Owner complaints say yes, heavily, as a model-year pattern. 36 of 59 relevant complaints filed with NHTSA about the 2021 Buick Encore concern the engine, transmission or fuel system (61%), and the largest group is filed under engine (18). For comparison, the 2020 scores 49% and the 2022 scores 66%. On a test drive, check for stalling, loss of power, rough idle, oil consumption or a check-engine light. 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.
