Even in other industries it is common that spare parts and consumables have a very high margin (while the initial purchase has a much smaller margin or in some cases is even subsidised).

The most well known example is probably printer ink/toner. (Razors is another often quoted example.) But this applies to car parts too. I needed a new small plastic clip to my Dacia. I was quoted 100 SEK (about 10 USD) for that. I 3D printed a sturdier version that will last longer for less than 5 SEK in materials (less than 0.5 USD).

From that you can estimate the approximate margins many companies have for spare parts. Of course being able to prevent cheaper third party parts will seem enticing if they want to maximise shareholder value. And this is why we need regulation.

It's also absolutely no secret that fattest margins and profits for automobile industry is also made with "aftermarket service" - which include upsales and inflated prices for service intervals.

There's a reason they all now need digital service books which are locked to their partnerships.

This is honestly one of my biggest fears about the modern auto repair situation. Previously it was fairly common to eventually find service manuals for sale second hand after enough time had passed. Or someone would scan and dump them online. Then it turned into waiting for PDF's to leak from dealership CD's.

Now with having them locked down to dealership tablet pc's I worry they will never hit the public.

We need to bring back standardization and regulation of cars. Aftermarket parts for cars has mostly collapsed because NHSTA has deregulated almost everything. Auto manufacturers have worked hard to try and stop any 2 vehicles from sharing parts. They are all bespoke, sometimes even to the model year of a car.

That's a big part of what's made it harder to maintain cars and has driven up the prices.

It should be possible, for example, to swap in a new infotainment system on any old car. It should be possible for 2 EVs from different manufacturers to swap batteries.

Price no, process yes.

John Deere hasn't been insane enough to soft lock their oil filters. But they do soft lock about everything else they can.

That price is absurdly exaggerated and the part is also misleading (an oil filter).

Two hours of labor to diagnose and then however long the replacement took + the cost of the part. $120 doesn't seem overpriced for that.

The time it must take to get a limited pool of technicians to drive out (40 miles) and do that work is probably the real issue. The price seems completely reasonable.

I agree that right-to-repair should be a thing but you're grossly exaggerating the situation.

Sorry but you are misreading the cost. The part itself is $120. The fee for the tech to travel there wasn't specified.

The article doesn't specify that and the quote is an offhand remark from the farmer himself. I read that more as "... and it cost me $120" as if that was the bill he paid at the end.

However, it is unclear but I think my point still stands, a $120 piece of electronics is an order of magnitude less than a $1000 non-electronic, non-mechanical oil filter.

The labor is a major part of the cost and a major reason for the lawsuit in the first place.

JD is charging anywhere from $130 to $210/hr [1] for labor. That is my point. And that $120 part can only be replaced by their technicians which means that while the part itself might be reasonably priced, the labor is forced.

That's what was being said about that part, it's a cheap part which you have to spend a lot of money on the labor to install it. The farmer spent from $380 to $520 to install that part. Not exactly that far off the $1000 mark.
