Not my car, but a colleague has a four month old model, which due to the cold weather is giving him 100 mile range on full charge (seen with my own eyes).

Anyone else having a similar issue? The car is booked in for early Jan to be looked at.

Surely this can’t be right?

It's not right. Although it could make for an interesting YouTube video if you are prepared to put the claimed range to the test.

It’s really not great, usually he would get 250 miles on a charge, the cold weather just seems to be playing havoc with it. Not really fit for purpose if the drop off is so steep.

Electric cars will always suffer a drop off in cold weather (just think of how many ICE cars won't crank because the winter has murdered thier battery) but that seems a little excessive. I'd certainly be talking to my Hyundai dealer to see if there is an underlying issue.

Does his have a heatpump or not?

Even my Model 3 SR+ with a 48kWh battery achieved 150 miles at -3 a few weeks ago on a motorway run.

It sounds broken!

Could be the same problem as someone else in the UK about 12 months ago. He reported 128 miles range when it was 8C outside, and he was driving economically too.

Turns out it was the 12V battery and the main battery having dead cells.

"Just an update on my car.

It's been sent down to Tilbury (Hyundai's import dock in London) where I'm assuming they are more equipped than my local dealer to deal with battery issues.

They found an issue with the 12v battery reporting as missing completely, even with a new one and some damaged cells.

This means that all the functions that use the 12v for power were using the high voltage batteries thus affecting range, paired with the fact that the High Voltage batteries also has dead cells accounts for my awful range.

Doesnt look like I'm getting the car back until mid February at the earliest as that's when my hire care gets returned but could be longer."

Definitely something not right there. The lowest predicted range I have seen from my I5 (72kWh, AWD, 7 months/5.5k miles old) is 203 miles with 100% SoC. Turn up the heating and blowers would reduce predicted range by 30 miles.

Am I correct that some ioniq5 have only a 39kwh battery?

I believe the two options are 58kWh and 72.8kWh.

It’s so long ago we had our Zoe and with such low range then it was basically always on charge when not being driven, so I cannot recall.
But a very basic question as I was asked over Xmas and just didn’t know.
When range reduces like this, is it because the battery cannot take enough charge to go further, or does it take a full charge and just translates to less miles.
And same question with battery degradation. If a battery has say 90% of its capacity still at a few years old, whereas when the car was new, it took say 50kw to charge it up, will it now only take 45kw to charge it, or will it take 50kw, bit only give you 45kw for use?
Question was in relation to pence per mile based on the newer much more significant electric costs.

It's the actual capacity of the battery that degrades - so if you've lost 10% capacity due to degradation, you'll 'fill' the battery using roughly 10% less power, and go 10% less far.

I think I read that in addition to capacity degradation, the anode in li-ion cells degrades which can affect charging efficiency - which would decrease charging efficiency but probably not to an extent it's worth factoring into running costs.

Sounds like a fault. My i3s never goes below 100 miles and it only does 130 max in the summer. Even after 4 years it's still the same.

A visit to the dealership is in order I think as Hyundai are supposed to be much better than most.

^^^ This. It's obvious that something is very not right.

Loss of range is something that manufacturers really don't want too many stories about so I imagine Hyundai will take it pretty seriously. I'd have been on the phone to them within 12 seconds of getting in my EV if the full charge range was suddenly halved.

Update on the story! Car went to Hyundai before Christmas, they charged it to give a range of 260 miles. Then after it was driven possibly 10/15 miles the indicated range went to 80! Needless to say he is completely frustrated, Hyundai are less than useless, booked in again (soonest is the 13th of jan). It has to be a battery issue, which I think they know.. but are trying to avoid accepting. It’s his first bev so quite discouraging! Talking in the office today he indicated a swap for a Tesla would be welcomed!

I wouldn't be mugged off like that - I'm almost certain I would manage to have the car picked up within 24 hours and a courtesy car delivered with a little targeted persuasion.

Glad to hear they're taking it seriously now (as they should've in the first place).

Hope you're back on the road with it soon, although can imagine it's a big job!

It’s less than a 1 day job…..but the big job is getting the battery availability!
Our 2019 Kona EV was part of the global recall….took about 11 months to get a slot.

Not entirely unexpected.. Glad they've taken it seriously at last.
