I believe your heart is in the right place here but what you're saying is you believe what a magazine tells you other people are saying rather than believeing the people who tell you directly on this forum
In this instance, happy people are irrelevant, you don't need to know that XX% of owners are happy, what you need to know is that there have been YYYY number of failures of a certain part or parts. There may well be 100,000 perfectly happy RX300 owners out there but what is important is to know if/that there are 1000 reports of transmission failures, and that after xx date there are only 25 (or however many) failures . By homogonizing the data CR minimizes the seriousness of those failure. IMHO forums like this one are far more valuable then CR for making car buying decisions.
