Modern vehicle owners feel savvy these days talking about K Services, like your first big 30k service after buying a new car. Unfortunately, this is because dealers promote the idea of K Services by creating a myth that something special happens at these intervals. And they've matched that myth with inflated service prices over their "regular express lube" lanes.
Our philosophy at Atomic Auto (backed up by experience from hundreds of Hybrid Intermediate Services performed): Yes, your hybrid vehicle needs to be serviced every five thousand miles, but there's a list of the exact same maintenance that needs to be performed every time. And these items aren't always performed by dealers or other shops.
Of course we will occasionally need to replace standard things that wear out, like tires, brakes, spark plugs, coolant, belts, et. cetera. These are discrete service points though and not part of the overarching care of responsible hybrid ownership.
