I have a 2006 V6 LR3. Has anyone had problems with the driver seat becoming uncomfortable and sinking in the middle. Mine has began to sink and is now very uncomfortable. I am a large person 275 lbs and one of the reasons I purchased the vehicle was that it was comfortable. I have not talked with the dealer about this and was wondering if anyone else has had similar problems. I have 32,000 miles on my LR3
