For the OP, welcome to the Tucson Forum. But as this one is focused ONLY on the latest gen NX4 (released in only '22 here and '21 overseas) there'll be nearly no owners yet with the kind of miles for requiring those type of servicing to contribute any feedback or personal experience.
As mentioned, the cost of any service will be astronomically different depending entirely on whether done by:
- yourself, with the biggest incentives being the wages are usually 1beer/hr., and no O/H or Hazardous waste fees. You do have to figure in stuff like paying (very little it turns out) for subscription to access an online Factory Service Manual, or just cheap-out on youtubes as mentioned. You'll need some basic equip. and tools, but those usually pay for themselves before halfway done with the work. And then you get to keep everything on top of that. Forever.
If using a shop (way preferably a mom-n-pops privateer vs. a "gittem' in an out!" franchise chain type), they'll have acquired enough familiarity with the tech and systems on these rigs by then to do the routine servicing you listed.
Lastly, the dealer rates are up $140-180/hr., (hey somebody has to pay for all those 'free' donuts, wifi, coffee and tv while you're waiting). And factor in a dose of the 'ol added in,
"other issues we found and completed". And just be braced for the well-rehearsed assault,
"Look how dirty and worn your [transmission fluid - oil - cabin filter - wipers - tires - alignment - brakes] are, and right now we're running a special!....."
In agreeing with others' opinions, the recreational therapy, emotional well-being, immense cost savings and assured increased safety and quality of life for myself, my family and all others ever riding inside make it a lead cinch obvious choice for the first option.
But one recommendation for collecting some real-world numbers by owners having relatively a lot more miles would be to post in a forum that includes the older models as well;
