So my Nissan Xterra 2006 has started making a weird noise about a week ago. I haven’t noticed any problems while driving it but id really like to figure out what’s causing the noise. It routinely starts when I start up the car after sitting parked for a while. Example, if I start the car up to go to the store it’ll make the noise but after turning the car on and leaving the store I don’t hear it. The noise lasts just a little while and is loudest at about 20mph. So once the car is warmed up I don’t hear it. I can’t really pinpoint where it’s coming from because the car has to be in motion driving forward for it to start.
It sounds like it’s coming from under the car. I’d like to hear some second opinions from some more experienced people on what it could be.
