Vibrating and rattling after 20 miles

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! If your 2020 Jeep Cherokee vibrates and rattles after driving about 20 miles, it could be heat-related. Common culprits might include a loose heat shield or exhaust component expanding as it warms up. If the vibration is tied to speed, check the tires, wheel balance, and suspension components—worn CV joints or bushings can cause these symptoms. If it's drivetrain-related (feels through the floor or steering), the driveshaft or transmission mounts could be worth a look. Best bet: Have it checked before something works itself loose and goes from annoying to dangerous.
