Hyundai currently have a recall on all Hyundai Ioniq Electric 38kWh models where the original BSC-1 coolant (a low conductivity coolant) is flushed out and replaced with BSC-2 coolant, due to the original coolant crystallising within the cooling system. The first indication that your vehicle has this issue is the "Refill coolant" message on the dash. This only affects the 38kWh model (2020-2022), as the previous 28kWh model (2016-2019) does not have a water cooled battery pack. My 2020 Hyundai Ioniq 38kWh has this issue and is booked in to have the recall work done, but the dealership had a 3 week lead time. So in the meantime, is it safe to drive? I was wondering if the deposits left by the coolant crystallising would hamper the cooling of the battery pack. So in this video, I try to test this. I did a two hour motorway drive and checked the battery temperatures and then again after another one hour drive and a 40 minute DC rapid charge.
