Well from here, Canada, by the store i was told that when the camera is sent to the manifacturer it might take from 3 to 6weeks.
Altho the store i bought it from has 1 year full replacement warranty (I paid for an extra year.... so 2years) Along with 3 years after the 2 years where any repair will be done in store by specialists.
Maybe have a look at this option if you bought it from a store that can fix the problem you have
Also, if i recall, they mentioned something about being able to follow the progress of the repairs of your camera through pentax website
