Buick occupies the top spot among mass-market brands for the second year in a row. It is followed by Mini, Volkswagen, GMC and Chevrolet in the rankings. Jeep had the worst score among mass-market brands in the study.
Overall average satisfaction with dealership service fell from a year ago.
Scoring is based on dealer service performance during the first three years of owning a new vehicle. The study is based on responses from more than 70,000 owners and lessees of 2010 to 2014 model-year vehicles.
Among the findings:
*Dealers that offer some type of express lanes for customers who do not schedule service appointments substantially outperform those that do not offer this option.
*Satisfaction with the dealership is also higher among customers who work with the same service advisor they worked with in the past.
*Satisfaction is higher among customers with a recall visit than among those with a repair visit.
"Even though recalls can create a large influx of customers into the service department and really strain capacity, automakers are better prepared to handle recalls than they were a few years ago," said Chris Sutton, J.D. Power vice president of U.S. automotive retail practice, in a statement.
"It is possible to turn a potential negative into a positive when it comes to recalls if they're done in a way that doesn't inconvenience the customer."
Edmunds says: This study provides some critical information for car shoppers who are factoring dealership service into the equation as they ponder their new vehicle choices.
