I have a 2004 GT2 with 34,000 miles. Recently began to notice clicking, popping coming from the front end when turning wheel from left to right. Dealer indicated the noise was coming from an aluminum subframe attached to the front end and the engine mount. The tech said the problem has been common with cars having the aluminum subframe. It is currently in the shop and requires a replacement part, being done under warranty. I'll post again when resolved.
