I cancelled my consumer reports years ago, don't really think they offer what I wanted. Although they aren't influenced by advertiser dollars so they aren't biased that way, they are an organization with members and are biased by their members. My main complaint is I think they test everything from a common person perspective, which doesn't apply to me as an enthusiast. If you want to buy no hassle transportation and as point A to B driving, they are good. For an enthusiast? Not as much. Same with everything, cameras, etc.
Take the Jeep Wrangler for example, they rate it horrible every single year, yet that vehicle receives almost no updates and sells extremely well, and has higher resale value than almost any other vehicle. It is a smart buy if you want to drive off road, or don't care that it handles like crap on the highway.
I agree with some of their assessment with the Volt, but they use more opinion in their than they should. They are spot on with the center stack though, and that is a big complaint to me which might prevent me from recommending it to someone, but don't care so much myself. I think the Volt 2 will be a lot better as a car for most people.
My other complaint with CR are factual errors. They have botched numerous tests over the years (including one calculating cost to drive hybrids, child seat tests, etc) Even this report is no exception. They say they got 35 with expected range of 40 in original Volt, but the EPA range is what, 38 miles (not 40). The new one should have EPA range of 50, so maybe they would get 45 (not the 40 that they mention) under similar conditions, that is a fair increase. It would mean for me, even on cold days, EV only I would easily be able to avoid gas (assuming I can disable ERDTT).
