I've learned to REALLY take anything CR reports on with a massive grain of low-sodium salt substitute.
I used to work at a high end mountain bike shop (the first of its kinda, and at the time still the only of its kind). We started getting a lot of calls at once about a "Giant Iguana" ("no, we only carry regular and small iguanas"). Turns out CR recommended it based on several factors, including the fact that the frame came from the same factory overseas that Specialized frames came from. What CR didn't know, or care to factor in if they did: Specialized did have frames come from the same factory (along with two other brands), but they have their own QC people onsite inspecting production output, and they also provided their own tubing that was to their spec. The other three brands, including Giant, were mass producing low-quality frames (bad alignment, poor welds, etc) out of marginal-quality tubing. But to CR, that was the same as what Specialized produced.
CR isn't a good consumer tool, unfortunately.
As a rider who's gone through... 6 or 8 BMWs? The only electrical problem I've ever had was: Grip heater stopped working (new grip, not cheap) and a sparkplug porcelain "unseated" and wobbled in and out so it didn't ground well, which left me running on one cylinder most of the time with the occasional firing from the bad plug. But, that's more NGK's fault than BMW.
