MINI leads all mass market brands in dealership service customer satisfaction with a score of 887 out of 1,000 in JD Power’s latest rankings. Porsche (915) remains No. 1 overall.

Porsche is followed by Infiniti (912) and Lexus (900). Last year’s mass market leader, Subaru (886), moves to No. 2, followed by Buick (882).

Customers surveyed for JDP’s 2026 U.S. Customer Service (CSI) study give dealers an overall satisfaction score of 868, a three-point improvement from last year’s report.

As ever, service departments have room for improvement, analysts say.

“Only 26% of customers say they experienced nine or 10 of the top CSI Key Performance Indicators (KPIs), including value-enablers like being met at the vehicle upon arrival and having work completed properly the first time, among others,” the report states. “When all 10 top KPIs are met, average customer satisfaction is 979, but when only three are met, scores plummet to 632.”
