Just got a Honda Civic EX-T, 2018, with about 22,000 miles. When I'm driving about or more miles per hour, I start hearing a semi-louder clicking kind of noise coming from somewhere inside of the dash, almost behind the speedometer. My local Honda dealership has pulled apart the dash, driven around with the dash open to try to figure out what's going on, and assigned a more senior engineer to take a look. They say the problem isn't diagnosable and therefore not fixable. But something has to be making that noise. Has anyone had this issue before? Did anything you had done fix a similar issue?
