Do you have the windshield cowl defect like 100’s of others of us? Wondering if water has been leaking right there from it? And yes, I would be concerned.
Just looked under the hood, I have the cowl defect. It is almost in line with that part in your photo. That part looks like cast iron. My truck only has 140 miles on it so could be a future problem. That defect looks like is only bulged at the top, the cowl looks flush below it..
