Thanks for your comments. I have already "eaten" it - i.e. I've paid for the repair. However, the information from the metallurgist suggests that the castings was hardened improperly (something to do with flow lines within the metal). If SAAB knew this (e.g. because this problem occured frequently) then I'd be very disappointed - even if not in posession of a case for liability! How common is this cracking problem? I've certainly never heard of it on any other vehicle. If it's more common than on similar types of cars, then it's a manufacturing fault or a design fault. I'm interested to know.
