Steering Rack Failing. Replacement not available
 

Hello I'm new to this forum.
I have a 2014 GMC Sierra 1500 2WD 4 door (66k miles). In March of this year after a routine maintenance, I was informed my steering rack and pinion (electric) was failing. Currently a replacement is not available. I have ordered one through Summit Racing who will receive one from ACDelco. Original ship date was April 10 then pushed to May 8 and now pushed to August 8. The local GM dealer cannot provide one either. Has anyone else had this issue? Is it not available because it's a widespread issue? Apparently not a recall, however it can result in steering failure and possible accident.
Now I can't rely on my truck through the summer for travel and camping. I'm stuck and GM doesn't seem to expedite delivery!
Any suggestions? HELP!
Thanks in advance.
