Blown turbo in Ranger

We've bought three Ford Rangers and are about to buy a fourth as, until now, we have loved them as great to drive. A few days ago one of our employees heard a pop from his engine and was towed to a Ford dealer. It was determined a turbo shaft had snapped in two, sheared and sent fragments through the engine. The entire engine and other components needed to be replaced. The car was bought in 2012 and had done just 120,000km with a full service history. Ford Customer Care said they'll review the claim and advise of the result in 4-6 weeks after they get the paperwork from the dealer as the claim is more than $10,000 from the dealer. They advised they may not even accept the claim even if it had faulty components to begin with.
