As reported by Autocar, only 6 Ferrari 458 and 10 Californias are affected in the UK and going by the same ratio, there could be a few stricken Ferraris in South-East Asia (including grey imports). Ferrari is currently writing to all affected owners so that the affected cars are brought in to the nearest dealer for repairs. And as the problem warrants a replacement crankshaft it would mean an engine out job with new conrod bearings, gaskets, seals and what-nots.
This could be pretty good to those who actually rev their 458s and Californias silly as they would end up getting a free rebuild from Ferrari even with the low mileage that these cars usually rake up.
This is a good deal in some ways. Much better than the flammable adhesive that caused a few Ferrari 458s to catch fire when it was first launched.
