Side/window Air Bag problems of the 2005 Toyota 4Runner

I own a 2005 4runner sport 4. 7l. I bought it brand new from gene reed Toyota in charleston, SC. This is not my daily driver and stays in the garage most of the times. It only has 59k on it. This past weekend I was dusting it off getting ready for a Sunday drive and noticed a crack starting at the gauges and following the curve on the dash all the way over to the top of the radio. I just drove it a week ago and that was not there. I have never used any chemicals on my dash, only a damp cloth. At first glance I thought it was a factory seam. I pulled it out of the garage and into the sunlight where I could see it better and sure enough you could see the yellow foam inside the crack. I went to google the problem and could not believe my eyes at all the same, exact problems that were going on. There are thousands of complaints with the 4runner's dash cracking for no apparent reason. I am very disappointed in Toyota with the quality of materials that they used to make this dash pad. My vehicle is in mint condition and has been garage kept it's entire life. This seems to be happening mostly to the 2003-2005 4runner's all over the country. I have read that other owner's have contacted their dealership and Toyota motor sales USA, inc. About the problem and they have all refused to do anything about it. This needs to be resolved by Toyota because I have noticed the crack is getting bigger when it expands in the heat of the sun. The dash pad goes directly over the passenger side airbag and if the cracking continues it could make the airbag malfunction and deploy unexpectedly. I have read other 4runner owner's are very worried that the cracking dash will effect the airbag too. Toyota could at least pay half for the part and let a Toyota tech install it.
