I bought a new KIA Seltos in Feb2021, after a few weeks discovered that the rear Aircon vent is blowing warm air when Aircon temperature control set at 24 degree celsius even when the outside temperature is at 35 degree celsius.
The Aircon front vent will blow warm air when temperature set at 25 degree.
I book a appointment 26 April 2021 with KIA workshop and they claimed that this Aircon system is normal and did not rectify the problem. They claimed as below;
During the visit on 26 Apr 2021, inspection was carried out on the vehicle’s Heating, Ventilation and Air Conditioning System; the values such as Ambient Temperature Sensor, Evaporator Temperature Sensor, photo sensor, In-car air temperature sensor and other related values that maintain the operation of the climatic air-conditioning system. We did not find any abnormalities in the values and all sensors and actuators are functioning normally and a diagnostic scan with the manufacturer’s diagnostic scanner did not report any diagnostic trouble codes. These data was also inspected and compared to 2 other similar vehicles and the performance was found to be similar and thus the vehicle’s air-conditioning system was judged to be operating normally.
That's radiculous and silly.
