JD Power Releases Car Brand Dependability Study

The 2012 Dependability Study polled some 31,000 owners of 2009 model-year vehicles measuring problems they experienced in the past 12 months.


To understand the numbers you see listed below, the "overall dependability" is determined by the level of problems experienced per 100 vehicles (PP100), with a lower score translating to higher quality.

In this year's study, J.D. Powers found that overall vehicle dependability improved substantially as the industry average was 132 problems per 100 vehicles, representing a 13 percent improvement from last year (151 PP100), while it's also the lowest problem rate since the survey began in 1990.

Wow. Not what I would have guessed in several cases.

I wonder how much the data would change with a larger sample size..

 

[KennyGS]

I assume they use a large sample size then express the data in problems per 100 vehicles. :shrug:

31k owners doesn't seem like a lot, seeing as how every brand has quite a few models/makes/trim levels... heck honda has 11 different models alone. The study has 32 brands on the list

I'm sorry... I misunderstood you.

I agree. Not a very robust sample size in terms of the total population the data is meant to represent.
