JD Power has a number of surveys and it is important to understand the context for each. IQS is the Initial Quality Survey, and it is basically "What defects did new owners notice".

Additionally, simpler cars have fewer things to go wrong. Disclaimer: I work for General Motors, this post consists solely of my opinions.
