We leased a 2017 Soul EV+ in spring of 2017. In November the OBC failed. It took 4 months, but Kia paid to barge the vehicle to Seattle (we live in Alaska, and Kia does not sell any EVs in Alaska), fix it, and barge it back.
Haven't had any problem since.
Some internet sleuthing revealed that failure of the OBC is not uncommon among Soul EV owners.
