KIATECH, thanks for letting people know that there could be an end in sight for this problem.
I have dealt with Japanese companys in the past and I know that even when everyone else knows there is an issue, that until the company's engineers have diagnosed it as a product issue and not an enviromental one (ie, regional, user issue) AND have a soultion, no official recognition will be made.
Funny thing is, I don't think I've expereinced this problem myself, at least not to the extreme level that some have described. I have the 2.4l with 12,000 kms now and no seriuos issues. Maybe I'm just lucky?!
