2018 Buick Encore: engine and transmission complaints

VERY HIGH COMPLAINT SIGNAL
68%
42 of 62 relevant owner complaints are about the engine, transmission or fuel system

68% of relevant owner complaints filed with NHTSA on the 2018 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 89% of the 1,230 model years we track (2010–2023).

Excludes 12 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 57%).

Manufacturers fix things mid-generation. A bad year next to a clean one is common; the fix usually arrived in between.

Other subcompact SUVs with no elevated signal in 2018

The percentage is each model year's drivetrain complaint share. No elevated signal describes the model year, not any one car; a well-kept example of a flagged model can still be the right buy, and any of these still needs an inspection.
