Thanks for sharing. Had same issue and odb Link error code in our Hyundai 2017 sonata PHEV late April. About 80k miles, ev battery was only getting about 23 miles per full charge. Brakes went out when coming to stop, car shuttered, essentially stalled and hybrid/system warning came on to turn off car. Turned off at stop, Waited a few seconds, turned on, then was able to drive w engine light on back home to check odb error. Was barely able to get it to dealer, and it stalled twice on the way there upon stopping. Loved this car up until now. will be hard to trust this battery system again, as I'm near end of warranty. At least this repair will be covered and dealer is waiting on battery replacement, but it's been a few weeks already and no ETA... Seems it will take a long time.
