Owned the car for nearly a year...just now getting around to reading about the hybrid battery warranty in California. I had assumed it was the same as my old gen3....nope - it looks like 8 years or 100k miles. Bummer.
Wow! I just looked and saw the same thing. Big difference between the 17 Prime and the 18 Prius. I didn't look at the 17 Prius, but assumed it the same as Prime.
another recent thread said gen4 is only 8/100. i agree, bummer. there are enough failures between that and 10/150 to make you think twice
Toyota has stopped talking about HV battery reliability, and we have had no further surveys by Consumer Reports. So I do not know where we stand, but I am thinking the they got the bugs out so most owners will see over 10 years/150k miles. Not sure about the Li packs in 2-eco.
Well the lithium packs in Teslas hold up really really well. So maybe we can expect the same thing out of the Prius battery pack.
For 2016~2018 model year, Lithium battery packs were in all levels except base. And the base NMH pack was revised somewhat, more compact, in order to fit in the same space? For 2019 I think it's somewhat similar, except the AWD levels are also NMH?
OK I seem to forget my Gen4 battery line-up in USA. I do recall 2 eco had Li and +4 MPG over Base had NiMH, but we never knew what the explanation for the +4 MPG was due to Li or wieght class difference in the tests etc. Well interesting though to see how the Li batts hold up at 8-year mark...sheesh that's 2026 hope we make it to see that answer.
IIRC here in the UK, we've always had the 8yr/100k miles warranty on the hybrid battery, except when I had my Prius+ with the Li-Ion battery it was only 5 years for some reason.
I must be getting old.... the part that bums me some is that it never occurred to me to actually check the warranty BEFORE purchase. Still.... we really like the car and having just retired, we don’t put all that many miles on it. Thankfully I’m not commuting the 100 miles/day any more.
Yes - it's an interesting question. Oh - it wasn't a question - but I'll still answer. With NiMH, they seem to be standing up better with 15yr old PRIUS than much younger Nissan LEAFs. But then - the PRIUS is an occasional use battery - relatively - if it gets hot, it just closes up shop for a minute or 4 till it's cooled down. LEAF hasn't got that benefit - and has to either work or not work. And, I'm not so sure that the quick charging of full EVs is particularly kind to batteries - but can't find any comparisons between some which were always quick charged vs ones which "trickle" charged nightly at 110/230 volt. Plus they're still working on new designs of battery - and I'd not be surprised if we're talking the same thing in 5 years time - that the new Al-ion?? or Ni-Fe?? (or whatever) batteries have taken over from Li-ION. They're desperately searching for better. My experience with Laptop and phone batteries - Li-ION haven't given me particularly good vibes about them long term.
I thought so too. Maybe you could find something on your local TOYOTA or LEXUS website re CARB warranty.
The battery management and thermal management is key in Li-ION life. When treated correctly they will last as long as NiMH. In a phone it is the thermals which kill them off quickly.
