Whether or not its an issue, is the only thing that is being determined.

It seems to be clear from reading all the posts that ethanol in the fuel will cause it to chirp.
Clearly it is an issue for most owners to have a noise like this on a new car.
What isn't known is the extent of any damage being caused by the lack of lubrication to the HP fuel system?
