Originally posted by HoustonBob Consumer reports is probably the least reliable testing organization out there; they try to test everything under the sun. Testing a vacuum cleaner or a breakfast cereal is hardly like testing a camera. In other words they don't know what they are talking about; its the "jack of all trades master of none" phenomenon on display there. I used to believe in them before I got involved in electronic engineering back in the early 1970's and learned how much you have to know about a subject before you can even begin to do accurate testing.
I tend to agree in regards to their reviews/testing and take those with a grain of salt.*
That being said, I don't remember anything in my comment about reviews or testing.
I was talking about their survey-driven product reliability estimates. In addition to product testing, CU surveys their members several times a year regarding the reliability of their purchases and the types of issues that they encountered. I have taken part in their camera, electronics, auto, and appliance surveys several times. At present, the camera reliability figures are the result of predictive statistics applied to five years survey results with the current crop including data from 2010 through 2015. The numbers project the percentage of cameras that may fail or require repair by year three of ownership.
In other words, no cameras were harmed or tested to determine reliability ratings. It is actuarial science in action, similar to that used for determining insurance risk and projection of election results. I know enough about that stuff to be dangerous (graduate coursework in prob 'n stat) and to appreciate what they have done. I find their camera and electronics reliability ratings accurately reflect my personal experience as well as that of friends and acquaintances.
To be complete, here are the current ratings (projected failure rates at three years) for interchangeable lens cameras, by brand:
Panasonic: 4%
Canon: 5%
Sony: 7%
Pentax: 7%
Nikon: 8%
Olympus: 8%
According to CR, differences of less than 5 points are insignificant. They also include a YMMV disclaimer.

* I use their ratings as a way to start product research, particularly for price/feature spread. Often enough, my purchase decision will match their recommendation/rating. Case in point might by my Lawn Boy mower which cannot handle the heavy growth of damp grass typical of my region, but also refuses to die. That goes to show that I am at least as dumb as their staff.
