Service 4WD

Got “Service 4WD” message on my H2 display several times now. I just had it in 2 weeks ago for service so “now what?”. Ran it by this morning and the diagnostic code came up as C0306. Service guy looked that up and it said “there is an intermittent open in the t-case actuator motor”. So they replaced the actuator under my extended warranty plan. Parts and labor $460. My cost $100 deductible.

Was reading some forums tonight and it seems that it is not a rare issue but a few guys claimed that the actuator motor can suffer from lack of use. What does that say about my offroading lately? Guess it says I use my own 2 feet more than my 4 tires on the dirt these days.
