Let’s take a beat here and consider two things. First is that Toyota has increased the warranty on their 2020 hybrid battery systems to 10 years and 150k miles, for what is essentially the exact same technology they’ve been using now for years. Second, manufacturers set warranty limits at points that they believe will be met by at least 99% (or more) of the cars they sell. Since no component in a car fails at exactly the moment in time when the warranty limit is reached this means that for these 99%+ cars many of them will exceed those limits. Perhaps 75% of the cars will make it to 200k miles; 50% to 250k and 25% all the way to 300k. In fact, many uber drivers using their Prius cars have reported that their cars are still going strong at 275k+ miles.
Are they expensive to replace?....you bet. And I agree that replacing individual cells is a fool’s gambit; do the whole pack when it’s needed and start fresh again. I’m not certain about these aftermarket companies and their replacement packs.....more time is needed to see what reliability and longevity they achieve. My point is that these devices aren’t suddenly going to ‘pop’ within 10k miles of their warranty limit, which is anyway now 150k miles and ten years, a number that most likely has been increased owing to field data amassed by Toyota for the millions of these cars that have/are roaming the streets and still on their original packs.
Consider also that Toyota’s ancillary components and software are programmed to never charge the pack beyond 80% of its capacity nor let it fall below 40%. These limits are well known to squeeze maximum life out of this (now) ancient but very well proven NiMH battery technology. A well maintained Toyota hybrid with regular maintenance at 100k miles should not be something to hide from, just because its own battery warranty has reached its limit; limits that were established before even Toyota knew just how good their own product would be. Use it as bargaining leverage to get a great deal on a great car!

So you are advocating spending 6k for a new dealer traction battery (which may be new or reconditioned). The same thing with the replacement dealer battery,in the future if 1 cell goes weak technically the battery pack is BAD. versus someone who if they did it themselves could get cells for $35 each, with his free labor, or have DrPrius do it for $600. Of course we all know the remaining cells can fail anytime in the future. But that is like anything else in life.

I have had 2007 gs450h original traction battery last easily past 262k miles

Current 2013 es300h with 179k easy no problems.

Taxis in NYC 400k plus miles easy.

Have you looked at any es350’s? No hybrid battery to worry about.

It really isn't a worry...

no one with a hybrid actually worries about the battery.

my 2016 ES300h I just passed 122k on mine and no problems so far
I have seen a few for sale with up near close to 200k and the claim orignal batterys still
Toyota Hybrid taxis in NYC have like 300-400k on them
toyota is the best hyrbid system on the market i think.
i read somewhere the honda uses the toyota hyrbid system they leased it from toyota i belive that shows how good the toyota system is

Look the hybrid will battery will go out eventually. It might not even be your problem as you might not keep the car long enough for that to happen.
