I have taken my 2009 Wrangler X in to the dealer 2 times now because of this and I just don't believe its "a normal thing." Its not every time but its pretty often that when I park on any kind of incline (facing uphill or downhill) after I put my emergency brake on and I let off my brake pedal a loud pop or cracking noise happens. I think it kind of sounds like breaking a piece of plastic. Both times the service reps said that they couldn't find anything wrong with it and its cause the brake is on my back tires. If this has happened to you or you know what it could be please let me know cause I don't really feel like waking up one morning and seeing my baby at the bottom of my street. Thanks
