2022 Hyundai Kona: engine overheating

Filed Sep 21, 2026 · Engine · WA

My radiator has coolant leak. I noticed the fluid getting low and the smell. I had to put fluid in 2-3 times the last month. I took it into the shop and they confirmed that it is the lower left part of the radiator that it’s leaking from and it has to get replaced. I did notice on a campaign 24\-EM\-005H\. for the Hyundai Kona 2022. But my VIN number wasn’t part of that. It is having the same leak and I have to get the radiator replaced. My car has 65000 miles on it so it wasn’t covered under warranty. It is in the auto shop now and will cost me over 1200 to get it fixed.

The vehicle displayed a warning lamp indicating a Cooling System Performance failure. The specific defect relates to the Integrated Thermal-Management Module (ITM) and the thermostat opening prematurely, corresponding to Diagnostic Trouble Code (DTC) P218100. This issue requires a repair outlined in Technical Service Bulletin 25-EM-007H, involving a spring installation and ECU update. This failure creates a serious safety concern because improper thermal management can cause the engine to overheat or force the vehicle into a reduced-power 'limp mode' without warning. A sudden loss of acceleration or engine stall while driving in traffic significantly increases the risk of a crash.

I had the radiator replaced by the Ourisman Hyundai Laurel dealership on 10/1/25. Radiator replacement was under warranty. On 10/4/25car overheated while driving. I pulled the car over and called for a tow truck. Car was leaking lots of coolant. Brought it to service center at Ourisman Hyundai Laurel, they stated “the hose to the thermostat was not all the way on. Put hose on correctly no more leaking.” On 10/15/25 multiple lights came on the dashboard including the master warning light. Took car to Ourisman Hyundai Laurel again; received the car back, dealership stated “ TECH COULD NOT DUPLICATE THE LIGHTS POPPING ON DASHBOARD. UPON FURTHER DIAGNOSIS TECH FOUND THAT THERE WAS A CONNECTOR NOT GETTING THE PROPER CONTACT TO COIL NUMBER 1 TECH RECONNECTED THE CONNECTOR AND TEST DROVE THE VEHICLE FOR 5 MILES. NO CONCERNS PRESENT AT THIS TIME.” On 10/20 I brought the car in to Ourisman Hyundai Laurel again because Electronic Stability Control light as well as ABS warning light and several other warning lights came on multiple times. Ourisman Hyundai Laurel service technician said they could not duplicate the problem and there is nothing they can do. This is a safety issue because it concerns the electronic stability control and brakes.

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.

I was driving up an incline when I overheated, causing smoke to come out of the transmission case. The vehicle suddenly stopped in the middle of the road, which could have caused an accident or fire. Regarding the transmission, I opened the hood to let the vehicle cool down for an hour.
