OK, time for a weird noise question:
Today, just after starting my car, as I was driving I heard a noise that sounded like paper shuffling in the back seat. I pulled into a parking spot and got out and checked the back seat and didn’t see anything odd (or anyone) there.
I continued driving and then (I think while braking, not sure) I heard a weird hissing/gurgling noise almost like someone letting fizz out of a soda bottle. It sounded like it was right over my head, behind me. Then I heard what sounded like something falling from the back seat onto the floor. (a light thud but it sounded close to me, inside the car) Then all noises stopped and everything was normal for the rest of the 15 minute drive home.
I seriously doubt it was the brakes though I was told my brakes will need replacing soon.
I have definitely heard noises behind me that turned out to be in front of me and vice versa so I suppose it could have been coming from the front. When I got home I cleaned out the back and looked under the hood and seats to see if there were any animals in there. Didn’t see or hear anything.
Any ideas? I know brakes can squeal, grind and vibrate but can they hiss?
