Every Buick, ranked. Lower is better. 100 is the average car.
Each score covers that model's own model years. Buick wasn't one of the 22 brands in our 2010–2022 study, so it has no brand score.
More Buick models with owner complaints. No score: we don't have their U.S. sales by year, so each page shows the complaints and recalls.

143The Lemon Index counts owner complaints filed with the U.S. government (NHTSA) in a car's first 3 years, per car sold, against the average car of the same model years (100 = average, lower is better). It measures complaints, not crash safety. How it works · Every brand
