The J.D. Power Initial Quality Study is now in its 36th year, with the latest running of the study looking at the responses from 84,165 purchasers and lessees of new 2022 model-year vehicles. Those surveyed were given a questionnaire made up of 223 points that break down initial vehicle quality into nine separate categories, including powertrain, climate, driving assistance, features, controls and displays, exterior, interior, seats, driving experience, and infotainment.
The study was fielded between February and May of the 2022 calendar year. Using the responses collected, J.D. Power calculated the average number of problems per 100 vehicles, a metric dubbed PP100. The lower the PP100 score, the higher the vehicle quality.
Among the 33 car brands studied, GMC ranked seventh overall with a score of 162 PP100. The ranking places GMC above Cadillac, which scored 163 PP100, and below Lexus, which scored 157 PP100. The industry average score was 180 PP100.
The top-ranked car brand in the latest J.D. Power Study was Buick, which scored 139 PP100, a massive 17 PP100 improvement compared to the Tri-Shield brand’s twelfth-place finish in 2021. Buick finished above Dodge, which had a score of 143 PP100 for second place, and Chevy, which had a score of 147 PP100 for third place.
Looking at the broader automotive industry, the latest scores for 2022 indicate an industry-wide decrease in initial vehicle quality, with an 11-percent increase in average PP100 scores, up 18 PP100 to 180 PP100 as compared to last year. Supply chain disruptions and other complications are indicated as the driving force behind the decline.
GM, however, was not part of the broader trend, and was one of just nine ranked automakers that actually improved in initial vehicle quality year over year.
