NHTSA Complaint #11657069 — 2008 FORD EXPLORER

I got the car from my landlord, my husband never checked the oil or fluids even though I was on him, it died 2 months after we got it, the guy said before we purchased it that it still was under warranty for transmission, so when it died I thought ok it's covered, so the landlord said it was the motor it seized he said had no coolant and was 2qts of oil over I said well he never added anything & I said it never overheated, he said I don't know how it was done but it will cost $3800 to fix, so I was hoping that there might be a recall that can fix this or also he puts new rear in the car a week after I got it, does any of this sound like it is his side that is reliable to fix it?
