I’m fairly sure the harness issue is largely impacting bmw. This would be the first I’ve heard about it causing an issue for hyundai. It may be speculative but it does seem like they’re getting the kona and EV6 out much faster. Also MG seem to be getting their new electric car out quite a bit quicker too. My neighbours ordered theirs via motability around the same time as me and they’ve had it delivered recently. Could well be hyundai slowing production of the car.
