Lately I have been hearing this noise when I am driving around 40 mph. Sometimes under sometimes above but it is also around or close to 2000 rpm. The noise I hear is something like grinding but if I let go of the gas it will go away. I only hear it at 40 mph or 2000rpm at the 40 mph area. I also hear it towards the front passenger side. I am wondering if anyone else has heard this noise themselves. I took it to the dealership to see what they think but they want to keep it a few days to see what it is. I dont want to leave it there cause they will charge me. Hope I get some help.
