Default Long term reliability: gas vs. hybrid?

It seems to me that more components introduce more things that can go wrong.

On my prius I love not having a timing belt but I’m not fond of batteries that degrade.

I've wondered this too. I still see a few gen1 Priuses on the road, so i imagine the the hybrid system is pretty reliable.

Hybrid have been found to be more reliable for two main reasons:
1 The added components forces car makers to use the most reliable platforms.
2 The availability of high voltage supply allows replacement of some mechanical belt driven components with fully electronic ones in AC, pumps, portions of brakes, power steering, etc..

For example:

Fully electric are even more reliable with lot fewer parts, lack of fluids ( coolant, oils, etc.j, lower heat, little cooling, etc. There is the current discussion that once electric cars become the norm, the whole auto repair and service economy will be greatly affected.

heres my 2 cents

first RX we eveer bought was a 2009 RX350
loved the car fuel consumption sucks on it
2nd RX was a 450h loved it cvt was abit weird but got used to it
3rd RX is now the current RX 5 seater
4th RX is the new 7 seater

as you can see with our purchaseing order
we prefer the hybrid over the gas powered sibling
its more quiet better on fuel and the extra weight does make the car feel more stable and luxurious

maintenance wise i didnt find any price difference between the gas the hybrid
there is nothing really special about the hybrid in servicing wise
uses the same engine oil takes the same amount of oil oil filter fuel filter same thing

my 2012 camry hybrid with 74K kms still runs strong and averages @ 5.2L per 100k which gives it around 1200km of mileage on a full tank of petrol
and toyota/lexus hybrid batteries are backed with 10yr warranty anyways

i wouldnt go back to a petrol version unless its a dedicated sports car
last week i traded my 2014 gs350 for a 2017 gs450h as well

Consumers Union (CR) reports that the long term reliability is virtually identical for either version (based upon a very large and statistically significant data sample over a long period -- a decade). Feel free to pick either one based upon personal preferences.

Hybrid components are backed up with ten year OR 100 000 miles warranty, WHATEVER COMES FIRST. As I drive over 20K a year, I'd be out of warranty in five years.
You know, I had 2 hybrids. Camry and Highlander. Camry was a very good car. Should have likely kept her as commuter. Highlander though developed a VERY odd issue, out of power train warranty, of course, that totally killed my love to this vehicle. It's the thing with hybrids. Yes, they may run for LONG time (come to Seattle, see all of them Prii running as taxi cabs) but, if feces hit the fan, and something goes wrong - it's EXPENSIVE repairs anywhere around hybrid components. There are many things you can't do on hybrids, maintenance wise, because of abundance of electronics. It's that Damocles sword, always hanging above your head, that killed my interest in them. Some gal did research yrs back, came up with conclusion that hybrids are 32% more expensive in repairs. Add to this normal Lexus sky high repairs costs.
Do you feel lucky?
Let me finish with a spec of humor

May I ask what the issue was and whether it was a common issue with your year, model generation of Highlander hybrid? Thanks.
