Just got back from 2100 mile road trip from San Diego to Big Sur, Mendocino, Avenue of Giants, Lassen Natl Park , and Truckee. Passport ran great Averaged 24.5 mpg. However, a couple days in it started making a strange sound which seemed to come from both sides of the front suspension. I could also feel it a little bit in the steering wheel. It so uh nded and felt similar to the sound and feel experienced when driving ok ver a cattle grate. Both lane assist features were off. No warnings from Collision Mitigation. It seemed to happen under a wide variety of road conditions but more often ( that will be another topic) on winding mountain roads than freeways. Am not able to reply ate intentionally. Anyone else experience similar symptoms?
