NHTSA Complaint #11581099 — 2024 KIA EV9

There was ~1/4" of slush on the roof of the EV9 when starting an in-town trip. On a back road when decelerating, most of the slush slid forward and down the windshield. It was very wet but frozen enough to create a lump under the wipers. It seems the EV9's wipers will completely stop if they are unable to fully return to their start position, and some of the ice was preventing them from doing that, and so they refused to continue wiping at all. I tried turning the wipers on/off and changing speed, but nothing would get them running again. Thankfully the back road I was on had no other cars, I had to stop on the road (I had zero visibility) and get out to clear under the wipers. Clearing was also hard due to the hood overhang design covering the wiper area needing to be cleared. If this had happened on the highway it would have been very serious.
