Hyundai IONIQ Electric, PHEV Come Standard With Lifetime Battery Warranty


Hyundai IONIQ Electric (and yes…another example of the windmill scourge following EV press vehicles everywhere)

With a price tag of just $29,500 in the U.S., the Hyundai IONIQ Electric, with its 124-mile range, is sure to be a hit. But there’s something else the IONIQ Electric (and the upcoming plug-in hybrid IONIQ) offers that you won’t find on competing plug-in vehicles…a lifetime battery warranty.

Hyundai/Kia is still tops in warranty coverage of new vehicles in North America, but a lifetime battery warranty wasn’t expected. However, there’s a slight catch. The warranty covers failure, but not capacity loss or degradation over time. Degradation isn’t covered by Tesla , Ford, Fiat, Mitsubishi and others either (see compiled chart below from Gary Exner of the Oregon Electric Vehicle Association).

Green Car reports states:

“If the battery pack fails, Hyundai will replace it free of charge and “cover recycling costs for the old battery free of charge to the original owner,” according to a promotional e-mail sent to customers.”

As with most automotive warranties, this doesn’t apply for commercial use.

SparkEV supposedly has up to 65% covered. It’s supposed to be in manual or some doc that comes with the car as checked by forum commenter, I never bothered looking it up.

A friend new SPARK EV has a pack issue. They said 80% was covered and fixed it no questions.
The IONIQ EV has a worlds 1st Lithium 12 volt starter battery too.


So what’s the largest degradation to be expected in the Ioniq? After 10 years/100K miles? 20 years/200K miles?

What determines a failure?


Degradation is not covered, only complete failure.


Yes, I know. What I’m asking is, what level of degradation would be considered a failure? Lets say one day I have 100% range, the next day I have 10%? Is that degradation or a failure? There’s a lot of gray area in between, so where is the line drawn?


And since degradation isn’t covered, what’s the expected amount (and/or worst case scenario)? This is important to know because if they battery degrades by 70% in 10 years, and it’s not covered by warranty, this decrease in utility/value needs to weighed when making the initial purchase.


“Failure” will likely occur when the pack voltage drops below the voltage of the power electronics in the car when the battery is loaded. That won’t be a specific capacity it’ll just be the point where the car can’t run. If you have one cell fail that could be less than a 10% drop in capacity but the car won’t start. If you have all of the cells degrade to 50% capacity the car could start and run but the ev range would be much lower. In that instance you would loose.

I think this is a reasonable way to do a PHEV warranty as it is not really possible for a battery to get to very low capacity and still provide the required power. Although that is heavily dependent on how they have set the car up.


Exactly what i was thinking, but i thought more extreme. What happens if battery degrades to 1%, but is still functional ie. Hasn’t failed? Sounds to me like offering lifetime warranty on those terms will be essentially be unclaimable unless you want to make lawyers rich.


Failure is failure. Degradation is degradation.

If some amount of degradation were considered failure it would be listed. Since it is no level is listed that means that no degradation short of failure is considered failure.


Failure is NO voltage NO current, degradation is not failure.


I don’t think you would get down nearly that far. The dendrite growth on the anode that causes the degradation would eventually cross the electrolyte and short the cell. That would make one group of cells useless, eventually this would happen to all the grouped cells. This seems to happen around 50% degradation.


What we have seen fail in battery packs on multiple EV models is the main contactor relay which results in a whole battery swap. That being covered is a good thing.

KIA/Hyundai is unwritten level of less than 80% is in need of a replacement by dealer. Most never lose more than 1-2% so far after 3 years with the KIA SOUL EV. It uses the same battery and cooling system.


Could it POSSIBLY be when the car will not run at all? No lights, no gauges, NOTHING? [After eliminating fuses, relays, etc?]

Or is that just too simple.

Texas FFE

What’s the point in having a lifetime warranty on a car you can’t buy. There still aren’t ANY Ioniqs for sale in the United States. Hyundai seems to be taking Mitsubishi’s lead in building up the hype and then not delivering, of course Ford is getting pretty good at this also.


You will have no issues walking into a Ford dealer and ordering a FFE. My local Ford dealer (Galpin Ford) has 6 2016’s in stock.

Texas FFE

There is only one new 2016 FFE right now in all of Texas and the dealer wouldn’t even let me test drive it. Besides, I have a 2013 FFE, I’m interested in the 2017 FFE, not the 2016 FFE.

Texas FFE

BTW, I’ve had a request in to my local Ford dealer for months to call me when production of the 2017 FFE starts, no call yet.


You’re right. Let’s ask the manufacturers to never ever mention anything about a car that is not yet available to buy on the lot at a dealer or directly from them in all 50 states.


Texas FFE

The problem is that a person gets scepticle of manufacturers commitment when they say they’ve got a new model coming any day now and they keep saying that day after day and that day never comes. You’ve got to be impressed with what GM did with the Bolt, during the whole production start GM kept the buying public very well informed and they generally met their milestone dates. GM made history with the Bolt and I hope there’s real long commitment behind the Bolt and it’s not just an effort to generate headlines.


Is that what is happening here? The Ioniq release date has been a bit choppy I suspect because people aren’t getting it from the right place.

Now if they miss the date next month I think we’ll have plenty to be annoyed about.


Original owner ONLY!!!!

Useless if you buy used!

Also, no commercial usage. So, uber/lyft is questionable.

It is a marketing scam. Hyundai doubt that many people will keep the car that long or rack up that many miles unless you use it for “commercial reasons” (which is void). Few that does, well they will be in a very small number so Hyundai would just pay for it.

Free “good” press worth so much more!


They do the same with their 10 year / 100K mile powertrain warranty with the rest of their cars. That warranty is only for the initial purchaser too.

I wouldn’t go as far as saying it is a scam. But yea, they are trusting that very few customers will keep their cars that long.

With that said, the subsequent owners still get 10 yr/100K warranty on the battery. That’s not too bad. Not lifetime, but not too bad either.


“the subsequent owners still get 10 yr/100K warranty on the battery. That’s not too bad. Not lifetime, but not too bad either.”

That is almost the case for everyone else as well. Partly that is due to CARB rules.


What good is a capacity warranty if ther is no gauge to display the capacity of the battery? Only Nissan was brave enough to have a constantly displayed ( not hidden in some service menu) indication of current battery capacity.
They paid a price for bravery too. I’ll take a TMS and a real capacity gauge such as Nissan has with a clear ” drops below 9 bars” warranty , thank you.
Course no one has that.
Good luck going into the dealership and convincing some service advisor your pack has degraded and needs to be replaced!


Bars are useless because a “SW update” can easily displace more bars than you have ranges for.

One of my co workers complain about that exactly. It says that she got 11 bars, but she can only get about 55 miles of range out of it before turtle mode in the best case.

She doesn’t drive fast either and we are in California.

I told her to get a GID reader or LEAF Spy. She complained to the dealer but it still shows more than enough bars so they aren’t going to do anything!

Bar is just a display for “dummies”..

Apparently you have never driven or seen a Kia Soul EV. Furthermore, I can read the BMS SOC and battery degradation using the OBDII port and an app like Torque Pro with the PIDs available on the Kia forum. No big deal.


A good reason to lease. Looking forward to hear what the monthly lease payments will be.


I’m so glad I live in a country where I don’t have to rely on sneaky warranties! At least for five years anything that may happen that isn’t normal wear & tear or provably due to user error is the sellers responsibility – or, if the seller has gone bust, the manufacturer.

This warranty is even less with than Nissan’s nine bars! At least with that one it’d be really difficult for Nissan, if they did so, to explain why they changed the representation, except to escape from warranty claims.

Lifetime warranty against failure is a good idea, just NOT as a replacement for the more relevant warranty relating to capacity. The Bolts 60% may be too low, but I totally understand that they are conservative and it’s only good to tell the customers we’re not 100% sure about this…

Mike (evbww)

IMHO, a battery warranty without a statement regarding capacity loss is not terribly useful to potential EV buyers. This type of warranty information can, at times, be difficult to find. My chart has the same information with a large number of vehicles without information:


Of course “conditions and exceptions may apply”.


Problem with Ioniq warranty is it drives down used or trade in prices making leasing more attractive. On other hand I see many Prius cars with 150,000 miles and still going strong. Bigger the battery pack , the more risk is involved because they cost more. Replacing Volt battery costs nearly half of MSRP,for instance. Hyundai should tell replacement cost


“Replacing Volt battery costs nearly half of MSRP,for instance.”

So the battery will cost $15,000 to replace?


Low estimate: $2500 High Estimate: $4000

Wait! Are you talking “Alternative Facts”. Okay, you got me, carry on then.


Tesla is going to have to do something with that warranty if they expect the model 3 reservation holders to follow through.

They aren’t that rich (like the Model S buyers) and they are somewhat “soft” early adopters. I don’t think they are going to be nearly as willing to hang themselves out for a $10,000+ battery replacement.

/and I agree with others, a lifetime warranty without specifying degradation doesn’t really mean much
