I have the same issue at the lower rear area just in front of the rear wheels, on a 2012, 5k miles white XF. Guildford dealer was told by jaguar it is not a warrantee issue and I have contacted Jaguar and await a call-back. Not fit for purpose is certainly the case. With a passenger door seal coming unstuck and hanging outside the car, this may be my last of 7 or 8 Jaguar's. REALLY poor quality control. Update 02/07/14: Spoke to Jaguar directly and they maintain it is not a warrantee issue. To say they were not interested, is an understatement. I also have a door seal which has come loose for the second time and consider this current XF to be the poorest build quality of the 7 or 8 Jaguar's I have owned. I hope Jaguar have a great new-business development team as they will not be keeping customers after such an experience.
