Some Jaguar XF owners report experiencing a whistling sound at speeds of 28-30 mph, which may be attributed to wind noise at higher speeds. Additionally, those who notice the whistling during stops might find it related to improperly adjusted latches or tumblehome. Furthermore, a whistling noise during acceleration could signal potential problems with the CV joints or differential. Owners should also be aware of the possibility of an intake leak, which may produce a whooshing or whistling sound under power. It is advisable for owners to have their vehicle inspected by a qualified mechanic to accurately diagnose the source of the noise and determine the necessary repairs, as repair costs will vary based on the identified issue.
