Hello everyone! I'm a happy owner of a 2008 SRT8 Grand Cherokee since a month. I wanted to ask for your advice. The car is running smooth, it has 48000km now. It has this strange noise when I push it hard in third gear mostly. It sounds like some kind of a supercherger, or an air turbine of some sort. Starts at around 2500RPM and goes until 4000RPM. I'm quite confused and not sure from what exactly does it come. I feel it like some sort of a scratch even on my gas pedal. With gradual/slow acceleration it doesn't appear. Does anyone have an idea? Thanks a lot in advance!!!
