BANGKOK: 2 December 2013 Initial new-vehicle quality in Thailand improves 28 percent in 2013, according to the J.D. Power Asia Pacific 2013 Thailand Initial Quality StudySM (IQS) released today.


  • Overall initial quality averages 84 problems per 100 vehicles (PP100) in 2013, compared with 116 PP100 in 2012. 
  • Forty-four percent of new-vehicle owners report no problems in the first two to six months of ownership, an improvement from 29 percent in 2012. 
  • Premium midsize car owners report the fewest number of problems with their vehicle (55 PP100), while compact car owners report the most  problems (108 PP100).
  • Excessive wind noise remains the most frequently cited problem, reported by one in eight new-vehicle owners. 
  • Despite a decrease in the average number of problems experienced, more problems related to noisy brakes, engine idling and squeak or rattle noises from the instrument panel/ dashboard are reported in 2013, compared with 2012.
  • Excessive fuel consumption is among the top five most reported problems. The study finds that fewer than one-third of owners were told about the fuel efficiency when they purchased their vehicle.

"Efforts and investments made at improving vehicle manufacturing quality in Thailand are starting to be reflected, as fewer owners are reporting problems with their vehicle during the first few months of ownership," said Loic Pean, senior manager at J.D. Power Asia Pacific. "At the same time, vehicle owner expectations are increasing. In particular, owner feedback indicates increasing sensitivity to build quality and comfort features inside the cabin, including air-conditioning, interior materials and the audio/ entertainment/ navigation system."

Initial Quality Study Rankings

Among the 78 models included in the study, four models from Toyota (Camry Hybrid; Hilux Vigo Champ Prerunner D-Cab; Hilux Vigo Champ S-Cab; and Hilux Vigo Champ Smart Cab) rank highest in their respective segments. 

Three models from Honda (Brio; City; and CR-V) and one model from Mazda (Mazda3) also rank highest in their respective segments.

The 2013 Thailand Initial Quality Study (IQS) is based on evaluations from 5,015 owners who purchased their new vehicle between October 2012 and June 2013. The study covers 13 different makes that include 78 different passenger car, pickup truck and utility vehicle models. The study was fielded between April and August 2013.
