well, well, well. i googled crack issue for my GX 470 2003. Like others, has been garage kept; i don't work so it has spent MOST of it's time in the garage. cracks just appeared last week. i am waiting to hear from local dealer after service talks with rep. sounds like i already know the best possible response from lexus. sounds like the basis of a class action lawsuit to me. This is absolutely ridiculous for a luxury car carefully cared for. Thanks!!!
