NHTSA Complaint #11577782 — 2022 HYUNDAI KONA

My Check Engine light came on and stayed steady (not blinking). The Cause for it is Unknown to me. I took it to the Dealership and they scheduled me to bring it in 3 days later, 3/12/24, to determine if it was something simple or if would take up to a couple days to fix. They assured me that if the light remained steady, I would be fine to drive the car. If it began blinking, then bring it back in. If the fix would take a day or more, they don't do loaner cars so I'd have to rent one (no cars to borrow and Ubers don't take wheelchairs). Approximately an hour after I arrived on 3/12 (I had to wait for my car), they gave me my car back. They had to order a part that was on back order that could take weeks or months to arrive. The part had something to do with preventing the engine from overheating, but I was not to worry so long as the Check Engine light stayed steady. They then asked how many miles I typically drove each day, "just around town, right?" I answered, usually, but that I was currently taking medical treatments for the next two weeks which involved around 70 miles roundtrip plus my usual daily miles. The Service person winced at that. They then told me that if the car overheated, to not worry, just pull over until it cooled off, and if it didn't, just use the Roadside Assistance service, then bring the car to the Dealership and they'll give me a loaner car (?!?) until my car could be repaired. A bit in shock, I left. After thinking about it, I find the Dealership's handling suspicious. 1) They didn't give me any paperwork. In all previous interactions, they've given me paperwork even if I've only had my fluids topped up. 2) If a back ordered part could take up to months to come in, it seems most likely to me that the scarcity is due to huge number of customers needing the part, not a supply-chain issue. I am disabled and in a wheelchair, so need my car to take care of myself. I hope everything is actually okay. If not, please help.
