Double Trouble - both batteries dead.

Hi Kong, we are having the same issues as you and any further updates from Hyundai Canada? Our 12v battery died being only 2 years old and our kid was stuck in the car until we were able to to unlock the doors with the emergency key since our Kona EV had no power. We had to pay a new one since Hyundai Canada only guarantees it for 2 years and we were a couple of months over. We had some 12v battery issues the year before and they failed to replace it since they said it was ok from their tests. We heard from another Kona EV owner that when the regenerative break system fails, it doesn't charge the 12v battery anymore which causes it damage/drain. We are located like you in Canada and our Winters get cold. With our new battery replacement for the recall R0183, we also noticed a significant range reduction up to 40% as we get around 285 km now. We had to fight to get our $250 for all the inconveniences since Hyundai Canada reduced our range by 80% remotely without our knowledge/permission. Our dealership can't help us and apparently they opened a case with Hyundai Canada but they haven't got back to us yet since they are assuming that our family or other Hyundai Canada owners will forget. They seem to be coordinating their efforts together to Delay, Deny and Deflect to assume their responsibilities from all these Kona EV lemons since we are getting the same error messages. We took photos of all the Kona EV error issues and from their diagnostics, they couldn't find anything while the proof shows the contrary. Transport Canada was no help to help/protect Canadian citizens and we would be interested to start an action like they did on South Korea if other Kona EV owners join us in solidarity!

 

I would like to address two things.

The first " ... With our new battery replacement for the recall R0183, we also noticed a significant range reduction up to 40% as we get around 285 km now ...".

When did you have your battery replaced?

Did you take note of the "serial number" of the old battery?

The second " ... we would be interested to start an action like they did on South Korea if other Kona EV owners join us in solidarity! ... ".

Months ago I started a thread about "class action".

My impression at that time was the answers from other Kona EV owners in Canada were "you are on your own".
