Now I'm putting those parts in vehicles that I'm repairing.
What happens when one of the parts that I put in goes to a dealership repair for a warranty repair?
It may be as good as the Ford part (it's the same part), but Ford has no record of the serial number on it.
Is Ford obligated to fix what appears to be a Ford part (what the customer thought was a Ford part) but isn't something that Ford ever sold, tested, or warrantied?
