I also have a hairline crack just like yours starting from the left side of the instrument panel to the right side of the instrument panel. I'm beginning to wonder whether this defect is common on GX470s. I bought a platinum Extended warranty plan thru Lexus when I bought my 2003 GX but they refuse to repair it.
Their explanation was that it "does not effect the safetiness to operate the vehicle". When the dealer sold us the warranty, they told us that the platinum plan would cover bumper to bumper. I am very disappointed because I felt cheated. I believe Lexus should come forward and acknowledge this defect and take care of the rapair.
How much did you pay for the Platinum Extended Warranty? Is this a warranty that makes the car a CPO?
My GX470 was purchased as a CPO, and Lexus Extra Care paid for the majority of the cost to replace the dashboard. I was surprised the total came out to almost 2000.00 just for the dashboard replacement! I ended up paying 489.00 for the labor. Also, they gave me an RX as a loaner vehicle for 5 days. It was nice!
It took 5 days because I complained about my driver's side speaker making a crackling sound. They replaced a Mark Levinson L front speaker, lubricate the sunroof, changed the oil and fill up all fluids to the right level. They also took care of the "clunk" issue. The total for everything was almost $6000.00 and I only paid $489.00. I guess a CPO is sometimes better than a brand new vehicle.
