Just remember the dealer's definition of Obsolete: "I do not have one in stock".
Or in some cases: "My parts supplier has none in stock thus it must be obsolete.
One month later it is the new part the supplier just got in.
Suggestion (And story)... I went to my local authorized service center for a Recall.. Little two bit part they likely had dozens in stock.. Service consultant says "Do you have the part?" I told her due to the dealer who sold it to me not doing the paperwork he PROMISED he woudl do I did not, I got my recall letter by E-Mail. She said "Can't do it in 2 weeks, takes us longer than that to get the part".. I told her schedule it, I'd get the part.
Went home,, Called a professional friend.. 6pm that evening he pulled in my back drive, handed me the part, and his business card... around six hours shy of 2 weeks later I handed the service consultant my keys and the part attached to my frind's business card..... nothing further was said.....
A couple months later there was a warranty issue...They did not have that part in stock either but arranged for it to be shipped Fed-Ex overnight.
My friend....The national customer service manager for the chassis manufacturer.
Yup. I got real good service afer that :)
The suggestion.. Call the folks who built it.. Get corporate on the job of kicking anatomy at the dealer.
