The car is a 2016 Subaru Crosstreck; it is only 3 months old and has less than 2000 miles on it. When I drive the car it makes a screeching / metal grinding sound, almost like I’m dragging a piece of metal under the car; it gets worse the slower I drive. I checked under the car, there isn’t anything loose.
When I wash my car, I spray water high pressure water under the car at a slightly upward angle. It is consistently 0-30 degrees F where I live.
I believe that there may be ice somewhere in my engine or breaks causing the sound? However, the engine should get hot enough to melt the ice while driving. It often gets louder when I turn, so maybe there’s ice in the suspension system? It has been happening for 3 days now.
Any ideas on what is causing the sound?
