When I'm driving around town in my base 2018 PHEV Clarity, I hear a faint, mechanical, rubbing noise that sounds like it is coming from the front tires. I don't hear the sound when I'm stopped nor does it get worse when I brake. At first, I thought it might be a stuck brake caliper but neither set of brakes are hot. I have about 10,000 miles on the car and mpg does not seem to be affected. The sound does appear to be getting louder, however. I thought I'd post in this forum before I make a service appointment with my nearest Honda dealer, which is 60 miles away. Anybody know what this could be? /Anybody experienced the same problem?
