The 2016 model-year Lexus GS.
LOS ANGELES: For the 17th time since 1991, Toyota's luxury marque has taken the number-one spot in JD Power's annual Customer Service Index (CSI) study.
The study uses 70,000 real US owners' experiences with a car company's dealers, franchises, and servicing centres and awards each marque a score out of 1,000. With 874 points, Lexus came top overall as well as in the luxury segment for looking after drivers of new cars bought or leased over the past five years (i.e., model year 2012-2016).
In the luxury category, Audi came second (869 points), Lincoln third (868 points) and Porsche (867) and Cadillac (865) completed the top five.
As for mainstream marques, Buick came top with 860 points, followed by Mini (850), GMC (837), Chevrolet (829) and Nissan (822).
Of the company regaining its position as the top marque for car customers after a four-year absence, Lexus group vice president and general manager Jeff Bracken said: "Customer service is at the heart of our brand, and we're proud of the continuous efforts by our dealers to exceed our buyers' expectations."
