NHTSA Complaint #11660783 — 2019 RAM 1500

I took my truck into my mechanic for a loud whining noise coming from my engine bay. I was told my alternator is going out. I have a 2019 ram 1500 5.7L v8 with the e-torque system. Part number 68438054AB or 68623194AB. This part you can literally buy from no one. Not a dodge dealership, mopar or any other website. There is about 1 listing I saw for a used one which was $1000 over what a new one would cost. If this part goes out I’m fully unable to use my truck which has 56,000 miles and is my only means of transportation. I have absolutely no chance of buying this part from anyone or anywhere at this current time. I can barely afford to buy the part even if it was available and I surely can’t afford to pay for a rental car or another car in the time it would take for this part to become available (if it does). From reading online and hearing what the Dodge dealership told me there is about 4,000+ people waiting for this same part. I still am paying a loan for this truck and I am at a loss on what to do. Insurance won’t do anything, dealership won’t do anything, and my bank won’t do anything.
