George,
Glad to hear things are well with you.
The reason I guessed it was confined to the USA is that most(except for one) of the complaints on the forums were from USA buyers.
I received this from Yamaha Canada Head office.... "we have not had a single complaint and no service bulletin was issued from Japan".
All the best,
Ian
