My car sits in the sun and yet is shaded by a tree in the afternoon for the past 3 years.. However, no way should this air bag compartment be breaking away on the dashboard where it is eventually going to "let loose" on it's own. If this is from the sun then there is something wrong with the manufacturing process of the plastic as this should not happen. The dashboard over the driver's area has cracked and broken from the sun a year ago.
