Hi all I purchased a 09 IS220d sport 6months ago and in the 6months it has been back to Lexus twice firstly with a rattle coming from the clutch/gearbox and also with rattles coming from the head liner in the back, rattles coming from drivers door and a loud crack from the dash. The flywheel was changed and the rattling areas were packed with sound proofing and they also said the plastic guides that are used to put the glass into the car were removed as they were the fault for all noise from the head liner. I payed my second visit to Lexus 2hours after I collected it with the rattle from the rear headliner after returning. They solved this by then packing the headliner with more sound proofing. I'm due to return this Tuesday to Lexus with the following problems: drivers seat and gator squeaking, dash making a cracking sound after heat has been on for 5-10 min, back shelf rattling, drivers door handle rattling and you guessed it rattle coming from rear headliner. Also while driving the car one night all power went from the car no warning lights came up on the dash. I'm just wondering are all of these problems common. From what I've seen and heard the dash cracking is a common complaint. I'm just wondering about the rest
