Interesting regarding this ground wire. One of my friends had an Ioniq EV, which occasionally had the peculiarity that the acceleration was delayed when he stepped on the accelerator pedal. It never happened from a standstill, but typically when the car rolled towards a traffic light after which it had to accelerate while the car was in motion. On Ioniq forums I could see that for some this was solved by adding a ground wire in much the same way as the video shows. Thanks Eric for showing this in your video.
I had that done to my Ioniq 6 weeks ago but never checked where they put the cable, thanks for showing that. Very nice blue color (just like mine) . Here in Sweden (400 km west of Stockholm) spring has just arrived and I will put the summer tires on next week.
Interesting. I'm in the UK and I've just had a recall notice for our 2018 IONIQ BEV for the update and ground strap but the noted symptom is a very small risk of fire when charging.
The extra earth strap can anchor anywhere on the gearbox. You don’t need to access it from underneath the car or to remove anything. I just bought an 18” strap from eBay and fixed it to a gearbox bolt that I could reach from above. No more hesitation problem.
I should add that I did this mod before Hyundai issued the recall. At the time I did it, my local Hyundai dealership were in denial and wanted to book the car in for “investigation”, which might have been expensive and certainly inconvenient. And the hesitation was intermittent, so not easy to reproduce on cue.
Thanks Eric for this update my wife has the 38KW version, I wonder if it applies to that model as well? On another subject have you replaced the gear reduction oil in your car? I replaced the oil in my Kona @ 35000km and it was black with lots of silver shine to it. The oil at the dealership is really overpriced @ $59 a liter, would love to find a better price somewhere. From what I've read on message boards both Ioniq and Kona suffer from this issue. The dealer feels it's normal? Funny all my years of changing oil in manual transmissions the oil was clear with the exception of the presence water, or if the tranny was on the way out it would be full of bits.
What is the steel wheel you used for your winter tires? Is it from another Hyundai? Also what is the size? We have a 2019 we just bought and I will need to put winters on for my wife next year. Thks.
I just cleaned these rims and can not find any markings on them. The tire size is the same as the summer tires. I am sure any place that sells tires will be able to tell you what rims you need.
I do. Just been really busy. The wheels came with the car when I bought it. Next time I am working in the garage I will look to see if there are any numbers on them.
