TrueDelta provides some interesting insight into automotive information and rating
juggernaut JD Power and Associates.
The site, which is developing its own vehicle reliability system,
points out how JD’s objectives may influence its information provided to clients (auto manufacturers) and the
public. TrueDelta believes there are weaknesses in JD’s Initial Quality Study (IQS) when applied to vehicle
reliability.

TrueDelta also questions JD’s definitions of problems (e.g., the infamous cup holders
and German cars debate, Hummer’s miles per gallon); rating system; the use of average; and “What is Best”
emphasis.  The latter, especially, is eye-opening on buyer behavior.
