I drive a used 2012 Nissan Sentra that I purchased six months ago. Today is the first time I’ve ever had problems with it. I was driving down the road this afternoon and it started making a noise that’s very hard to describe. It sounds like it’s coming from the dash and is comparable to birds chirping or a computer-like/electronic noise. It kind of sounds like R2D2 hijacked my car! It also started making a scraping like sound from the back wheel. I thought I was dragging something under my car, but there was nothing there when I checked. When I started it again later, there was a squeak when I backed up that was either underneath or the rear right wheel side. The sounds only occur when the car is moving. Any ideas? ---

How many miles on the car? I’m wondering if you’re hearing an audible brake wear indicator. Do you have disc or drum brakes in the rear? These come both ways. ---

I must admit that I know very little when it comes to cars and I’m not sure what type of brakes I have. I did some reading online and it does sound like it might be an audible brake wear indicator. It would explain both strange noises. I am going to get it to my mechanic in the morning. Thanks for your input! ---

I’d had a chirping sound from the dash area caused by leaves in the vents. A problematic fan motor/cage can make this sound too. The rear scraping sound seems likely to be coming from the brakes, or less likely a bad wheel bearing. A mechanics inspection would quickly prove/disprove.
