Many owners of Travatos with a roof rack (usually 2019 or later) report front end vibration at varying speeds. In many cases this can be eliminated by
1. Moving the front bar on the rack back several inches,
2. Removing the front bar of the rack, or
3. Installing an air dam in front of the front bar of the rack.
NOTE: If the vibration happens only when accelerating generally between 40 and 60 MPH then it’s possible that you need to have the front half axels checked as some had issues with those.
