Lexus, Honda, Daihatsu and Toyota scored five stars in the latest JD Power dealer service survey.

Honda and Lexus were the only two brands which had no negative comments.

The study focused on the customer experience at authorised dealerships.

Owners provided evaluations of their dealership experience grouped into five key measurements of dealer service satisfaction: service initiation, service adviser, dealership facility, vehicle pick-up and service quality.

JD Power said: “It’s not just that Lexus does the important things well, it does everything well. Owners rate the company as top in all aspects: fantastic facilities, superb staff, on-time service and faultless work.”

Honda owners said booking their cars in for a service ‘couldn’t have been easier’. The quality of its dealers’ work was rated as at least 85% by every owner.

Alfa Romeo sat at the bottom of the service satisfaction list despite commissioning JD Power to improve its rating last year.

“Most owners said booking their Alfa Romeo in to service was a challenge and when they did, the work was not good enough and the facilities were poor,” added JD Power.

The survey was based on questions sent out to 18,000 owners.
