Hey guys curious if anyone help with this issue. I have 2014 monogram frs . I bought from a Toyota dealership in 2016 with 28,000 on it and it now has 50,000. I went for check up because I discover an oil leak. As the dealship told me what's wrong with it the told me the motor and came out and been replaced with a junkyard Motor (which had no clue about). Since it's a junkyard motor it can't be cover under warranty. But what I don't get is why would they but a junkyard motor when was still under warranty? And my question is can I build a case to get a new engine or my money back. Any help would great pretty upset because now I have turbo just sitting in my room smh.
