<human>: I bought a 2016 Jeep Wrangler on 4/2. On 4/3, a guy hit me, causing me to be out of my vehicle for now two weeks. I took it to the dealer for them to fix it because I was scared I was going to void the warranty if I took it anywhere else, and I wanted it fixed right. I don't trust any of the mechanics in my area due to bad experiences so they were not an option.

 The work that I needed done was going to be way more than $6000, so I decided to let my insurance take care of it. Now, comes the part with my dealer. They have had it for a week, and since day one, they had all of the information of what to parts to buy based on the estimate from my insurance, and their own analysis. I called right after that to see what the progress was and they said "oh the parts are on their way." 

That made sense. I called two days later, and they said that they had almost all of the parts but the differential, and they were still waiting for that. The service guy said he did not know the exact date it would be coming in, but he could get back to me. He never did. I called again yesterday and now they tell me that they cant find the differential anywhere since my jeep is still so brand new.

 They said they can possibly never find it. I have a payment on my vehicle coming up soon, but I don't feel like it is fair for me to pay for a car that I had for only 24 hours and is not even being fixed.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Bought a brand new Jeep. Got in an accident day after. They can't find one of the parts I need anywhere. I need  advice on what to do next.
