With hybrid, you are having like two type of engine inside car, thus twice number of parts with failure possibility 

With this mentality, forever stick to Myvi/Axia/City/Vios/Almera, eventually only used car because new models are going high tech as well.

4 types of replacement parts usually.
- Genuine,
- 3rd Party "Genuine" (supplier not selected in this model AVL, but is supplier for other parts) 
- Reconditioned or Dismantled from total loss or half-cut
- 3rd Party Replica

The reason older generations think Toyota is reliable is not because things don't break, but cheap to replace with recond/3rd party replica parts when they break.
Their definition of repair is "able to run", not "restore to pristine condition".
Try to replace every single components with genuine at 4S, tell me if they are cheap again.

Once I had to replace 3x master brake pump within 2 years in an old corolla, and almost crashed. Sum up the cost is more than buying a brand new genuine at the first place. Buy a genuine then it has no cost advantage vs other "so call non reliable and no resell value" brand. Since then, why risk it? Just get any car I like, enjoy it, don't bound by society "reliability" and "resell value" perception, and do a proper repair, minimize the hack to make things "just able to run".

Continentals and for this case Camry Hybrids included have less reconds/replicas option due to modern electronics (components -> PCBA -> firmware, not as easy as copy the plastic mold).

But for some that always go back to 4S even for 10 years old car, car lovers that keep it at tiptop pristine conditions, do preventive maintenance, don't wait for things to break. Hybrid or not, it makes no difference to the service cost.

Battery price is going down consistently. From early 2010 it went down 20% year over year. Now it still over 10% year over year. Also circular economy is getting good traction, you don't throw away old batteries, they get second life in renewable energy power plant as buffer where power density is less of a concern.

You like it or not, this in inevitable. Car makers are trying to extract most values from the automotive industries, in the future more and more people would be going back to 4S. Bawah pokok mechanic is sunset business, the future 3rd party workshop would be run by proper proper engineers and the technicians have taken certification exam of a (if not multiple) car brands.

The world need progress, and is making progress. Bro, don't limit yourself, embrace the future.
