I have a 2014 Ghibli that I'm getting a squealing noise when accelerating up a hill in 3rd gear at low RPM, some times I can replicate it on the same hill, and on flat surfaces (rarely) but I have not been able to reproduce consistently. It sounds like a tires squealing in the distance, like when you go around a corner really fast and you hear that errr errr errrrr, (tires sliding) but higher pitched. I know it's hard to explain but it's really driving me nuts when I hear it which is kind of rare. It really only happens when I'm accelerating at low RRM in a gear like 3rd gear but requesting a lot of gas i.e. heavy pedal.
