I have a 2008 Lexus GX 470 SUV also. The paint is coming off everywhere. Lexus refuses to do anything to correct it. We all say the same thing - we love the expensive car and want to drive it forever but it is embarrassing to drive. Years ago I posted signs all over a vehicle I had that was a lemon. The Ford Dealership got it fixed immediately when they saw it.
Lexus does not care because the rich buys a new one every 1 - 2 years so they will always be selling.
I WILL NEVER BUY ANOTHER ONE JUST BECAUSE OF THE CHEAP PAINT JOB!!!!
