I think that applies only if you buy a new one after your 2 year warranty expires.
I had that prob with gen 2 bosh and had to buy my 5th replacement motor to get the 2 years.
I had four gen 2 bosh replacement motors under warranty. The last one was over the 2 year warranty so i had to pay for the new one, so then i got a new 2 year warranty because i bought the new motor.
Hope this helps.
