2014 Cruze LT, 1700k has started with a rattle from the passenger rear of the vehicle. I can hear it and my passengers that ride with me regularly can hear it but I'm worried the dealership won't. It's not very loud. I notice it because it was NOT there when I purchased the vehicle. I am taking it in to the dealership.... From what I've read, this seems to be an issue. I refuse to be walked all over. Any advice on what to say to the dealership to insure they listen and DO THEIR JOB vs give me lip service.
