The 2017 Malaysia Initial Quality Study (IQS) is based on responses from 2,843 new-vehicle owners who purchased their vehicle between August 2016 and June 2017. The study includes 47 passenger car, pickup and utility vehicle models of 12 brands. The study was fielded between February and August 2017.
Now in its 15th year, the study measures problems experienced by vehicle owners during the first 2-6 months of ownership. Initial quality is determined by the number of problems experienced per 100 vehicles (PP100), with a lower score reflecting higher quality.
