I understand, but even with a law, it is still a gray area and that's where the original question comes from.
I have also read that one forum member got his gearbox replaced even though this engine had a number of
mods known to the dealer. He said his warrantee claim was denied 2 times and on the third time it was approved. I was amazed, he should should definitely go buy a Lotty ticket. On the other hand I have also read posts where they lost out and had to paid out of their own pocket.
This is a risk to me, sometimes you might be lucky and other times you will not.
Maybe you are correct to say the question should be whether or not you are prepared to take Kia to court in the US?
