2018 Buick Enclave problems: engine and transmission complaints and recalls
49% of relevant owner complaints filed with NHTSA on the 2018 Buick Enclave are about the engine, transmission or fuel system. That is a model-level pattern, not bad luck.
Worse than 63% of the 1,790 model years we track (2010–2023).
Excludes 4 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 46%).
Does the 2018 Buick Enclave have transmission problems?
Owner complaints say yes, as a model-year pattern. 30 of 61 relevant complaints filed with NHTSA about the 2018 Buick Enclave concern the engine, transmission or fuel system (49%), and the largest group is filed under power train (15). For comparison, the 2017 scores 31% and the 2019 scores 68%. 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.

Should I buy a 2018 Buick Enclave?
That depends on the car in front of you, not just the model year. The 2018 Buick Enclave has an elevated transmission complaint pattern, so treat it as a car that needs proof: service records showing transmission work, a cold-start test drive, and an independent pre-purchase inspection focused on the transmission. A well-kept or already-repaired example can be a fine car; an unknown one is a gamble.
