So in the weeks since this all went down, I have personally been made aware of three more FIAT 500s that had engine failures exactly like mine. One of them lasted only 42,000 miles. What are the odds that one FIAT owner would know three other people who had the same problem?
And yesterday I heard about a fifth one. A friend asked on a message board if anyone else was having low oil pressure warnings while hot at idle. I advised him to go directly to the dealership immediately. I'm still waiting to hear what he's learned.
