The crack just suddenly appeared after I heard some rattling in and around the center of the dash board. Didn't notice until there was a 6" crack. Could possibly hinder steering column if plastic pieces from the crack fall into the area. Plastic shards could pose dangerous if accident were to occur.

Left rear seat belt fails to extract. Was told by dealer that the lock bar was seized up and could not be released and that the entire seatbelt would have to be replaced. This is only a 6 year old vehicle and at 6'4 270 I don't have anyone ever sit behind me. This is probably the least used seatbelt in my yukon. .
