I suspect all of this is because someone at Consumer Reports doesn't understand what he's reading. The Yahoo articles aren't their own reporting; they both say they're basically regurgitated from CR. I can't find any other articles about this from reputable
automotive sources (CR is great if you need a washing machine, but I've never known a gearhead who took them seriously), and there's no mention of it on the GM recall site 2 weeks later.
Here's a handy chart from GM of all their recalls to date this year:
http://media.gm.com/content/dam/Media/images/US/Release_Images/2014/05-2014/recalls/Recalls-Running-Total.jpg They have recalled so many cars this year that I seriously doubt they'd miss listing this situation or try to cover it up.
When you read the explanation in that second Yahoo article, it is the reason that the ignition recall was expanded to the later years (2008-2010 in the case of the Kappas) back in March: some cars may have left the factory with good parts and subsequently been repaired with bad at dealerships.
GM is capable of a lot of stupidity, but I refuse to believe this until I see something from a more reliable source or someone's notice that their car has to have the recall service repeated.
