Toyota warranty on EV batteries

[wivenhoe]

What is the Toyota warranty on EV batteries ? If you keep servicing at a Toyota dealer, is the EV Battery covered by the 10 year warranty ?

[Cyker]

It has its own separate warranty that's topped up by getting a Hybrid Health Check done every service (Or year, I forget which)

"Our confidence in the quality of the Battery is reflected by us providing up to 10 years Battery warranty with the Toyota bZ4X, provided through an initial 8 years manufacturer warranty from the vehicle’s registration date. In addition, 12 months warranty is included with every Toyota Service, up to 10 years from the vehicle’s registration date. Terms and conditions apply."

My question is - what are they warranting ?  What degradation are they warranting - 80% at 8 years or just total failure only. Nobody provides a warranty that the Battery will be 100% so what is Toyota’s. Lexus, on the same EV system as the bz, warranty 80% at 8 years. When I ordered the marketing info said they expected 90% at 10 years but this changed after the range update.

The standard is 80% but I'm not absolutely sure what Toyota's terms are off-hand.

Yeah, depreciation sucks - but it's not unique to EVs by any means.

For a lot of EV owners it's more the discrepancy in depreciation they're complaining about. Diesel went through a similar thing down here when the ULEZ and the ULEZ extension and the ULEZ extension extension happened - Used diesel values tanked and petrols and hybrids shot up as everyone tried to trade in their non-compliant diesel. The only reason diesels didn't drop as bad as EVs are currently is everyone outside London snapped up all those cheap diesels, but there's no such outlet for EVs.

I think, assuming the batteries survives, EVs depreciation will slow as the use experience improves, but not for a good few years.

The rightwing press in the UK doesn’t help matters, as they constantly tell lies about how often EVs catch fire. To read some newspapers, you’d think charging your car is positively dangerous and will burn your house down. There are hundreds of petrol fires every day but they don’t make headline news. The stats are that a BEV is at least 20 times less likely to go up in flames as a petrol car, but the papers won’t report that. They also have some mad idea in their heads that they are too heavy for car parks and the brake pads wear out in no time and cause more pollution, none of which is true.

Yeah, and ironically because the Chinese ones use LFP and not NMC-type batteries they tend to actually be less prone to catching fire than every other countries' who tend to use the more energy-dense NMC to get vaguely useful range. The downside of these batteries is when they do they are a lot harder to put out compared to petrol and even diesel as they have an annoying tendency to self-reignite which nobody's thought of a good solution for yet.

I think the press got bored of it as they did with normal car fires as both have gone back to being unreported for the most part  

I personally am waiting until batteries suck less so they can build one that at least has parity of utility with my Yaris before I look at them again.

Does anybody know what degradation the Toyota EV Battery warranty after 8 years. Having had a lot of new Merc’s I looked at their EV’s but their warranty only covered failures and didn’t guarantee a maximum degradation. So the Battery may lose say 30% capacity but if it doesn’t fail you cannot claim. Those with PCP’s will be protected against a drop in value but owners looking to buy for long term May be in for a bit of a shock. I think long term, EV residuals will reflect whether a car say 5 years old is risky or not.

It's taken me a while to find ... the Toyota European Newsroom site states:

Toyota’s confidence in the quality of the Battery is reflected in a guarantee it will retain at least 70 per cent of its capacity up to 10 years, covered by the original EV Manufacturing Warranty until 8 years or 160.000 kilometres, and with the additional Extended Battery Care up to 10 years or 1 million kilometres driven that is activated by an annual EV Health Check (T&C apply).

I haven't yet been able to find the equivalent statement in formal warranty T&Cs ...

Well done digging this out. They don’t make it easy as I think the majority of owners think that the up to 10 years warranty covers it. Nobody does, and it’s interesting that the bz is covered to only 70% but the Lexus using the same EV infrastructure is 80%.

70% is correct. 
Any bev has its huge negatives and one of these are exactly the heavy and expensive batteries.
Warranty on paper means something, in reality can be very different. Sometimes a simple misfortune like a water ingress can void the warranty and leave you in bad situation.
If you are planning to purchase an electric vehicle privately new or used you need to consider a traction Battery cost if you plan to keep it for sometime.  
Even hybrids has their risk with traction Battery failure. They do fail with age and usage and does indeed need replacements. They are way cheaper and way easier to replace out of warranty so I would say not such a burden like a typical electric vehicle.
