NHTSA Complaint #11687177 — 2020 KIA NIRO EV

I had just left my doctor after a protracted visit and was almost late for dinner guests. I noticed a thumping and thought it was the road, but it was a 3/8" bolt in my tire tread.I pulled up at Costco, hoping they could repair it quickly but was told I had to wait 2.5 hours when I had guests coming in an hour. I decided I would have to change the tire. When opening the trunk I found there is no spare, but saw a kit to fix the flat, which I vaguely remember reading about. I'm in a huge hurry to get home but I open the Owner's manual and there is: NADA about the flat repair. So I look at the components. There is a container of the repair solution and a pump with cartoons on it and a hose with a needle to insert into the puncture. After studying the cartoons for about 5 minutes (I am a highly technical, retired 82 year old ex IT professional), I figured out how to connect the can into the pump the hose to the pump and the power cord into the cigarette lighter (how many people still smoke and what would happen if the 12v socket disappears). I was then able to try to repair the puncture but it was for nought as the hole - duh - was too big. I also apparently ruined any chance the repair shop could repair the hole. The tire shop said my repair solution ruined the chance to repair the tire. Heaven help me if I get a flat in the rural boondocks!!!!! My complaint is: 1. What if this happened on a dark 2 lane country road 100 miles from nowhere and I were a single female or aged, frail couple? How would they manage to put together the repair flat kit with the hieroglyphic documentation on the repair kit pump? Could they be stranded for days without food, water, survival gear like coats or blankets? 2. Not supplying a spare doughnut tire could be imperiling vulnerable people. 3. The Owner's manual does not mention tire repair at all.
