Why won't my 2020 Hyundai Kona electric not open or start?

Asked by Jessica

I just took delivery of a 2020 Kona hybrid and five days later the car will not open from the remote and I have to use the skeleton key. Upon entry, the car will not start and I have to push the reset battery button on the side for it to start. This has happened twice in the 10 days since I picked it up. Anyone else with this problem?

This is still a very new model, so there’s not a whole lot of reliability intelligence available yet. Even so, I’m surprised that such a new vehicle has such a glaring problem just a couple of weeks or so out from its delivery as a brand-new car.

The reason the car won’t start when you open the door with the manual key is that the remote should not only unlock the car, but also deactivate the immobiliser and switch on the main electrical circuits that power the Kona. If the remote isn’t unlocking the doors, then it probably isn’t turning on the main systems either, and that’s why you need to reset the battery each time. Hyundai tells me that this car actually has a conventional 12-volt battery, mounted in the conventional place (under the bonnet, just behind the headlight) that powers the functions you’re missing. If this battery has a dud cell or isn’t charging (and it’s just spent several weeks on a ship getting to Australia, remember) then the car will exhibit the symptoms you’re seeing. A trip to the dealer is in order, but your problem is definitely a warranty issue.

By the way, your car is actually not a hybrid at all. It’s a plug-in electric vehicle. A hybrid uses a combination of a petrol engine and electric motor, your car is purely electric.
