Our 2017 EXL 2WD with the 1.5L turbo makes an occasional noise at speeds over 60 mph and sometimes at lower speeds, seems to come from right rear and sounds like something caught under the car flapping or ticking rapidly, but there is nothing there to see and it's intermittent. Wondering if it's something from the exhaust or a wheel issue. Only 3000 miles on the car. First time poster. Thanks.
