Not generally true. In addition to those mentioned, the Chevy Cruze diesel has an Adblue tank easily accessible in the trunk. Refilling the Adblue is no harder than topping up your wiper fluid. It takes a standard bottle with a built-in spill-proof adapter. If for some reason you don't have such a bottle, you can just use a regular old funnel. There's an idiot light type indicator that tells you when the change is coming up, just as with oil changes, and if ignored I think the engine will go eventually go into a kind of limp mode.
