Dang that's expensive to just replace some air filters and coolant fluid. Actually replacing the fluid is an interesting bit, by it's design the Tesla motors should produce significantly greater heat, IIRC GM's paper on this is that in a BEV it's some 20ºC difference from a power bar wound design that the Bolt has. This is why Tesla uses a water jacket for its motor - because they produce so much heat (additionally it's due to the poor choice of a pure inductive motor, but apparently the 3 has a permanent magnet like everybody else). Long story short, the Bolt fluids are very lightly used I'd expect, and the Model 3 is more heavily used, so perhaps that explains the need to replace it.
The initially more expensive bit is baloney, Musk said the average optioned price for the 3 is $43k. Few people will buy the $35k version (it costs $1k just to get anything other than black). Otherwise I believe the Bolt maintenance is a $15 cabin filter every few years, wiper blades, wiper fluid and replace the tires. Brake fluid replacement? Don't know why Tesla has that on there as you never use the brakes.
