Do they? Modern cars are using 0W-20 or lower weight oils solely for MPG/emissions purposes and pushing service intervals on that oil to 1 year for cost of ownership purposes. Then many people are not in the habit of changing their oil due to such long intervals so make that 2 years. Compounding that modern cars tend to burn a small amount of oil due to low friction rings for MPG purposes. I don't think you get long engine life with that recipe. That's not even counting the type of fancy things they are engineering into their engines like turbos, special valves, selective cylinder ignition (reduce V8 to V6 or V4) All that stuff breaks before 100k. It's a modern miracle a turbo last just 100k miles. In the aughts and nineties the extra emission equipment (mostly gas tank vapor emissions) would break after 100k miles, but it wouldn't stop the engine from running. Now it's even crazier stuff that definitely will.

Oh come on my '12 Odyssey has all that stuff besides the turbo and is happily approaching 200k miles. I see older Odysseys like '04-'08 on the road approximately all of the time. That stuff does not "all break before 100k". It would be interesting to see MTBF info for these new features, complexity _is_ typically the enemy of reliability, but handwaving based on your feeling isn't it.

  Prepare for a transmission failure. I have owned two Hondas and both had total transmission failures at that mileage. Neither were as new as '12 though, maybe the clutch packs were improved by then.

    Yeah 8/9/10 speed transmissions are another issue. So are CVTs

    Sounds like you were just very unlucky then :( I'm on at least my 3rd 200k+ Honda and only one of them ever had anything close to transmission issues (clutch went out). It could be because they were all manual transmissions however.

  I don't think your car from 10 years ago has all this stuff, plus it's a Honda. It's not my feeling. Just off the top of my head: See GM AFM lifter failure. See Kia/Hyundai engine failures. See direct injection carbon buildup on Lexus IS250. I could probably go on and on with some more research. I didn't even mention the transmission.. Nissan CVT is one of the worst but the Subaru CVT isn't even proven to 200k.

    2012 might be just on the cusp. Most cars from the 00's I'd put as being before this paradigm shift.

Motor oils are also getting better: https://www.mobil.com/xomfl/pvl/content/xom-annual-protection-v1.3.5/index.html https://www.mobil.com/xomfl/pvl/content/xom-annual-protectio... (Good for 1 full year or 20,000 miles, whichever comes first)

  Right. One of my points was that things you do once a year are difficult to make a habit. For a long time now synthetic oils have been good for 10 or 15k miles but people still had 3k or 5k intervals drilled into them so maybe once every few months was on their internal clock but once they actually took the time it ended up being twice or even once a year and that was actually fine.. But let's say the interval is now a year and you do it every 18 months? Is that fine? I don't know..
