Buick achieved approximately average reliability overall with its vehicle lineup in the Consumer Reports annual reliability rankings for 2024, published in the last week of November.
The Tri-Shield’s top individual models also were mostly average or somewhat above average, and Buick itself beat the typical reliability currently offered by American cars, the study says.
Buick scored 55 on a reliability scale of 1 to 100, which places it above the average dependability of U.S. automakers (39) and European companies (46), but below the average Asian brand (63). The Buick Enclave rated 55 like its parent brand, while the Buick Encore GX and Buick Envision each scored 47, about on par with European vehicles and still significantly ahead of the American average.
The study notes that vehicle reliability varied according to type as well. Cars offered owners the most reliable operation with a typical score of 57. Senior CR director Jake Fisher observed that “sedans have fallen out of favor with consumers, but as a class they are very reliable,” a fact he ascribed to their general lack of cutting-edge bells and whistles.
Meanwhile, SUVs and minivans were at the middle of the pack for reliability with respective scores of 50 and 45. Least dependable with a rating of 41 out of 100 were pickup trucks, though they remain some of the best-selling vehicle models in North America.
Different powertrains also performed at various levels of reliability. Using ICE vehicles as the baseline, hybrids are more dependable, with 26 percent fewer problems than their ICE counterparts. However, gasoline vehicles were far more trustworthy than EVs, with 79 percent more problems, or plug-in hybrids (PHEVs) with 146 percent more numerous problems than gasoline models. The Chrysler Pacifica PHEV had the study’s lowest reliability rating at 14.
The study’s reliability scores are based on how brand’s vehicles performed in 20 areas of potential trouble. These include a range of possible faults, from relatively minor irritants such as squeaks and noises to major failures like engine and transmission issues. Problems are weighted by severity to derive a final score.
The brands, including Buick, were assessed based mostly on 2020 through 2023 models. A total of 330,000 vehicles were involved with owners providing information on problems experienced in the past 12 months.
