Over the years I have noticed a number of details in the annual CR issue with vehicle survey stats. It doesn't give much detail on sample sizes, it doesn't weight importance of particular problem areas (I don't think many of us would have the same concern over a persistent issue with say an audio system problem versus a transmission issue -- though we may not be happy about it).
Then we add in things like the mentioned perception that a brand should get a free ride over others (though it may often be something to consider in view of past performance -- which I have seen them print in the reviews).
Then you add in the Suzuki Samurai and Izusu/Acura debacle. The result of the Samurai case (short version:
Top court lets Suzuki sue Consumer Reports / Automaker accuses magazine of rigging Samurai road test - SFGate)
ended in Suzuki and CR coming to an agreement that CR wouldn't use the Samurai results in any advertising (they could use it in editorials though). CR was alleged to have tested the Samurai and found no significant faults, but the president/manager needed a sensational case to help raise funds and asked the head of auto testing to toughen up the testing until it failed. Of course, if you are testing a truck that is primarily the 4 wheel version of a dirt bike to a sedan, that will not be too hard to do. They did something similar with the Trooper/Acura some years later.
So, even though we have a 'public interest' non-commercial entity, we have to remember that doesn't mean it is altruistic, just well intended. Until it becomes a living, breathing, organization. Then it is a life form that follows the number 1 requirement: first, stay alive. Just like government when it gets to a certain size. Regardless of intent.
Sorry for the hijack. I realize that this thread was intended to point out that GM cars seem to have improved. I am glad to hear that. And it does seem that they have been able to concentrate on building better vehicles, as repulsive as the methods used to get there. Can't wait until it is again not held by the public, but publicly held stock (might buy a couple of shares for pure symbolism, if not a good value). And I have to admit, I have liked the look of most of the newly re-designed cars. Wished they would sell some stripper version of the Equinox line (awd, 4 cyl, manual, decent mileage). That would interest my Forester driving wife.
