    I own a "07" GT 500 with 12,500 miles . New issue just started when it first starts, until it reaches operating temp the is a horrible squealing noise sound like coming from perhaps the factor idler or another pulley . Has anyone experienced this or have an answer .

    Sounds like a worn or glazed belt. Never mind the number of miles and replace it. It could have small age cracks (look with a magnifying glass). Also, check your tensioner for proper tension. :cool:
