I have a crack in the dash on the right hand side of the car. It starts on the plastic part only visible when the door is open and extends above the glove box door and into the vinyl on the dash. I have always garaged my car and if I am away from home have put a block out visor in to reflect the sun.
I have a crack in my dash. Always garaged. Why? on 2006 Toyota Avalon
March 2015 toyota finally issued a recall to have dash replaced.. You should have received in mail
There are a lot of post here on RepairPal on that very thing, same vehicle. Most were in Florida so i assumed it was just the climate but obviously not! One posted something about a class action lawsuit against Toyota but that is all the info i have. Google it, may be more info out there!
