I'd test this idea before looking at a repair, Does this happen at the end of the day when it's cold and you've been out in it for a while?
Even if it means buying a new battery, that's gotta be easier than sending it off for a check and quote, they'll want some cash even if they do nothing.
Batteries have a limited life span, and number of charges/recharges, I've found the "gas gauge" on the camera less than useful.
I've had similar effect, in my K3 classic, I can hear it happen, but have not been able to isolate it, very random, but it's less likely to happen with a freshly charged battery
Hope this helps
