I think that the expectations of longer term reliability is near the top of this list. I look at the list of items that we expect to service during the life of the car in the 1980's that we no longer look at.
- Ignition service (Plugs, Wires, Cap and Rotor) was generally done at 50,000 miles, my Ford Fusion recommends 150,000 mile internals.
- Transmissions are sealed. Hell, you used to be lucky if a GM 700R4 made it out of warranty for a 1980's GM C/K Truck.
- Speaking of 1980's GM C/K Series, we now expect that an engine is going to last the life of the truck, and you used to be lucky if a 305 V8 made it 75,000 miles before it was using 2-3 quarts between oil changes. Thanks to the LS series, we now expect that the engine will go 150,000 to 200,000+ miles before replacement.
- Air Conditioning is now expected to last the life of the car, and that was something that was considered to be serviceable.
Going to rattle off this list every time somebody complains to me about planned obsolescence.
