NHTSA Complaint #11467563 — 2014 JEEP CHEROKEE

I was driving on the highway and all of a sudden my car wanted me to shift into P to park while i was still in drive. My vehicle was hit passenger side as well in a hit and run incident. I pulled over and waited awhile and called the police then brought my vehicle home because it was not totaled. I tried to get coverage from my GEICO insurance but they were unable to help. Then February i was in a rear end collision from another gentleman on the way home from work. My vehicle was being repaired for a month and some change until i got it back. At first I thought it was the battery or alternator going bad, but a diagnostic test showed normal for both. I’ve tried different gas thinking it could be bad gasoline. When the vehicle shuts down it’s difficult to get it to restart. Now it is saying service 4WD which i believe is something with the transfer case because its not the axels or differentials which I had replaced from Jeff D Ambrosia. Looking for assistance to get my vehicle driving safe and possible reimbursement or help, I have all my receipts from what has been done to my vehicle since I first bought it in 06/20/20 For my birthday present. There is a lot of more information that i want an advisor or assistance to know as far as what i have already paid out of my own pocket with dates and receipts (battery, axels ,rear diffs , alternator , etc) and try to diagnose it from there. I know about the mechanisms myself and my buddy who is an authorized mechanic. I am sure that after hearing all the difficulties and safety issues i have had i may be able to get some serious help and even possibly with my right side of my vehicle ! Thanks
