I have a 2007 LS 460 fully optioned. The pillar between the driver's front door and rear door is showing tremendous wear in one spot on the front side of it. It is about the size of a knickel and getting worse. Has anyone experienced this type of wear? I'm very careful getting in and out of the car and let the seat belt return slowly. I've contacted Lexus in Torrance and have not heard back yet.
