NHTSA Complaint #11640076 — 2019 RAM 1500

My Ram 1500 front drive assembly issue. The initial issue was failure to engage in 4wheel drive. In either 4 wheel low, high or Auto. During replacing the transfer case it became obvious that axle in some way basically became welded to housing so had to replace left axle as well. Do to these problems I now have to replace front differential (part# 68349702AE and right axle (part# 68259567AA) as well because of the failure of transfer case and left axle. My issue is 1st the differential part is not available in my area (Nassau County NY). 2nd is that there is a recall for a faulty gear or bearing in the front drive train that my VIN# is not included in this recall. Could this bearing/gear have caused my issue? 3rd is if the front differential is on such a long back order that is telling me that Stelantis has an issue with the reliability of this part (68349702AE). Why if this is in such demand and numerous problems with them hasn't NHTSA not forced Stalantis to recall these parts. My truck is a 2019 Ram 1500 Laramie 5.7 Hemi with just 38,677 miles presently today. I have never taken this truck 4 wheeling or on the beach. The only time I have used 4 wheel drive is when the roads are slick due to rain, snow or ice, because of the light rear end. The last time 4 wheel drive was used was last years snow storm. Just don't understand hardly ever used and all this damage, truck was never in a substantial accident. I clipped drivers side back door and small section of bed, minor. Any information or help would be greatly appreciated. I'm already into this for $2500 and looking at another $3000. Thank You.
