I have a 2011 Cruze that is only about 4 months old - only had 24 miles on it when i bought it.
For about a 1-2 months I have noticed when my windows are down I can hear a whistling/squealing noise from the front end.. At first it was only on the drivers side and it was very faint.. Over the course of a few weeks it has became louder. So I took into the dealer and they said it was from the wind hitting off my side mirrors and they put padding it. But it was still happening, I called them and said its still making the noise and I dont get how it can be a whistling noise going at 10-15 mph.. So I took it back into the dealership a second time, when a several test drives with a tech and they shaved down my drivers side rotor.. I didn't notice it for a few days untill I had a passenger and they put down their window and then I could hear it from the passenger side. So... obviously I called again and took back in.. And they shaved down the passenger side rotor.. which now, its coming from both sides and its louder than ever.. It starts at 15mph and escalates from there and then slowly fades away as I get to 15 mph.The dealershop told me that if I brought it back in for the same problem I would have to pay for the service because it wouldn't be under warranty or I would have to call GM.
So anyways, I was just curious if anyone else had this problem? - I don't hear it when the windows are up and it is not an option for me to not put my windows down! lol..
