The passenger compartment climate control blower motor circuit suffered a severe thermal overload. The terminal overheated, shorted out, and physically melted the primary engine wiring harness (Part #91400-L0051) inside the main fuse block connector housing while the vehicle was operating. This caused an immediate smoke/fire hazard in the cabin and a total loss of window defogging and climate control functionality. This structural breakdown is directly tied to the electrical failures documented in Hyundai TSB #WTY037 / 25-EE-002H.

Engine overheating by model year
What owners say
My 2022 Hyundai sonata hybrid started blowing white smoke from the exhaust. Took it to the dealership and was advised the valve that controls antifreeze failed and leaking antifreeze in exhaust. This caused the engine to overheat and would cause the engine to blow up. My car has 83,000 and was told the manufacturer warranty only covered to 80,000 and extended warranty would not cover the part. Was told it would cost 2659 to fix. This is part of the hybrid power train and should be covered under the 100,000 Hyundai warranty. I have seen the same issue with other sonata hybrids on the internet that is doing the same as mine. Hyundai needs to recall for this since it is a needed component for the engine.
Vehicle threw a check engine light, warning lights, and overheated when accelerating getting onto the highway and accelerating to highway speeds.
Loss of power while accelerating. Engine overheat notification. High oil temperature.
Engine overheating warning. Hyundai cannot properly diagnose the issue.
Engine overheats under acceleration and fans run on high after car is shut off.
