Hi,
I have Chevy Cruze 2004 model and i purchased nearly. I observed,a humming noise starts after few kilometers drive. (its happened nearly, 1 month after purchased) its not big noise but slightly i can hear. i think its may be from gear box. why, one of the garage guy asked me " Is this model vehicle getting gear box jam? or any prob with gear " I said "No", because that time i didn't get any sound or abnormal condition. but now i am getting this slight noise.so i have fear and doubt about this noise. please advice..
