Warranty on traction battery, difference between Toyota and Honda

sounds like bull do-do. if you do know the parameters, what is the point?

 

It does not mention anything of the sort in my 2017 warranty book.
A troll posting for sure!

Provide your source. Here's mine.

maybe if you had a prime...

 

Both Toyota and Honda seems to say NORMAL reduction of battery capacity is not covered by warranty to me. I am sure both Toyota and Honda will cover if the reduction is such that it is abnormal. In case of regular hybrid system in Honda Civic, the battery was covered but only if IMA battery light is on and internal code indicate imminent battery failure due to loss of capacity.

Maybe not on regular Prius, but for Prime, the official warranty booklet (page 18) does mention exact wording OP posted on page.

neither will cover unless the battery throws a code, but who has the better track record?

 

Sorry I missed that this is in the Prime forum.

 

Pretty much all the PHEVs and BEVs have the same warranty speak. Capacity loss is not the company's problem except when it is so bad that it meets some random bar and then they'll replace it. Leaf, i3, Prius, Clarity, etc all the same. The only vehicles that don't have this is actually the Tesla S and Tesla X, but their batteries are so super awesome that it is not a problem. And if replaced under warranty, they guarantee what you get will be at least as good as what you had. For the Tesla 3, they added a capacity clause to the warranty absent from the S and X.

 

i've only lost 15% in 6 years, no worries.

 

May I ask how you figured "15%" loss? I am not being sarcastic. I don't know if there is some number I should be watching on my Prime for reduction of battery capacity.

 

i ran a whole summer of testing after i got my pip. measured my commute by temperature, rain, humidity and etc.

14 mile r/t commute used to average 2 miles left when i got home. now, i run out about a mile from home. 3 miles fro 16 is about 15%.

 

Thanks. So it is just empirical measurement of EV driving range. I was thinking there is a sensor or something that display traction battery capacity change over time. Or is there one, but Toyota is not sharing that information with us...?

 

likely there i s in the black box, but we will never see it. that's what makes honda's warranty above a joke.

 

it may not be true for everyone, my almost 40,000 miles of electric driving is 2/3 of total.

otoh, when it was new, getting 16 miles was 5 above sticker, and at 13 now, i'm still 2 ahead of the game.

so if you're at thirty something, and 6 years from now, you're still in the high twenties, you really can't complain, even the you'd love to see no degradation.

most of it comes in the second and third year, it hasn't dropped in a few years now.

 

kWhr's used is the best measurement from fully charged to depletion (hybrid mode). Doesn't the Prime/PIP report this?

 

PiP shows kwh on the EV driving ratio screen. There are two screens. I keep one for long term and the other one I reset when I get gas. So you'd need to reset it for each trip to know those numbers. That would mess up my spreadsheet that calculates EV and HV efficiency.

 

So far we really have no complaint with Toyota on battery issues.
On Gen2 they have replaced many HV batts under warranty at 8-10 years, never really asking if the user did something to cause the problem. They also bent over backwards to cover many cases a little over warranty date on goodwill basis.

Bottom line is, we have nothing to really complain about, except maybe some plug in owners would like zero capacity loss. I don't think any PiPs reporting in here ever had Li batt replacement.

 

I remember reading a thread here several months ago where someone did have to replace their PiP NV battery, but I sure can't find it now. That's the only one so far afaik.
