The manufacturer quotes in the article above are a blatant denial that this is a larger issue affecting more cars.
"The condition is brought on by a combination of normal mechanical variables"
To me, this says right there this is a mechanical design/defect issue and the ecu flash is a bandaid repair.
"Dealers now have the reflash to correct the issue."
Explain this to the owners still having the CEL issue after a reflash/new ecu/
"The condition causes no damage to the engine and a TSB is in-process."
This means they want you to keep driving your car even with a CEL. Sure it may leave you stranded somewhere, run like crap or stall at a bad time, but hey it's safe so don't worry!
