a loud knock started coming from my engine and i took it down to the dealer.They get it checked next mornign they call me and tell me they cant start the car so they had to rip the whole motor apart to tell me what happend and they couldnt tell me till the last minute ,they said that it "SPUN a Bearing" and it was only one that got jacked up so nobody up there had an explanation for that so my warranty company sent out a new motor and replaced it.Im guessing and thats just my guess it was oil pump gone bad or something. i never really cared to know what happend they put new motor i was happy plus the old one was smoking evrybody that drove behind me used to tell me that my car smokes ,but not after they replaced it .im waiting to get off work and i'll send you pics
