Door Latch problems of the 2006 Jeep Liberty

My Liberty has 3 recalls, 2 having do with big safety issues- fire and tires detaching. I first called planet Dodge (miami, FL) for service appt. ; gave VIN and advised of recalls- surprise! when I arrived for my appointment; they said the parts were on back order! today I called tamiami Jeep to make an appointment and was told 1) it's very dangerous as tires may detach 2) they have some parts, but not some bolt, if that is required! question- if these are mandatory recalls and on such potentially safety compromising parts- how can the parts be on back order for 3 months!! (this will be my first visit to tamiami for service appt-but was already advised not all parts available- what's the use of making a appointment if they is a nationwide of a part to repair a recall? what happens if my tires detach or my car has "underbody fire" as per my most recent notice? I would appreciate a reply via email and I would like somebody to investigate how service departments can run out of parts that have mandatory recalls. I was not told at planet Dodge how serious this was and have been driving around waiting for the parts to arrive. (lower ball joint).
