Not sure what the manufacturers will do in a case like this. I doubt they will appreciate the bad publicity they get from a brand new machine going tits up only a month after going into service. Not sure what is happening with the Koalas based in the US and Europe.
Many manufacturers I think, would be hard pressed coughing up monetary type payments in a situation like this. Its not like they can give them a replacement machine because in OZ all of them are grounded.
Time will tell. If I hear anymore from my contacts will post it here.
