The misfiring and detonation issue is another concern leading to this problem and its an issue that Subaru has had since the last generation of WRX's. Its enough of a problem that several tuner mags make quick mention of it, while saying its the greatest thing since sliced bread in the same breath. Take look at several of the WRX forums around and you may come to a similar conclusion, also keep in mind that relatively very few WRX's are sold nation wide.
I think this is a misrepresentation of the situation as far as the EJ25 motor goes. Yes, there is a known issue with it, in which some people experience piston ringland failure and detonation, (in cyls 1 and 4, iirc). Most of the community has isolated this issue to being due to a poor factory tune, and mostly present in 08 and early 09 models. I haven't heard of any '11 or '12 GR WRXs or STIs on IWSTI or NASIOC having that particular problem yet. And, the last statement there should be backed up with facts if you're going to make it at all, as up hee, the WRX and STi are extremely popular cars. I see WRXs here more often than I see the Golf. I live in the same neighborhood as three GD chassis STis alone.

But, the chart and OP honestly doesn't seem to have an unbiased representation in mind, so I guess the thread 'is what it is'.
