Kia EV6 heating problems 

Kia EV6

The Kia EV6 is a compact but stylish and sophisticated compact crossover SUV. It is also fast and practical, making it one of the best crossovers EVs on the market. With that said, it is crucial to know some of the heating issues with this car. So, what are the Kia EV6 heating problems? 

Common heating problems with Kia EV6 are a bad thermostat, a failing heater blower motor, a damaged heater core, and a bad heater blower motor resistor. Furthermore, several users have also registered water leakage, leaking coolant system, and failing heater hose. 

What are the common heating problems with Kia EV6?

Failing heater blower motor

The work of the heater blower motor controls the airflow for the heating and cooling system. But after some time, the heater blower motor may fail. If it fails, the air conditioner and heater may still function, but the air pressure will be greatly decreased. This will take place at all fan speeds, and all temperatures.

Some of the signs of a failing heater blower motor are a grinding or rattling noise that comes from the passenger floorboard every time the heater or air conditioner is active. If you’re having such issues, you should inspect whether the fan blades are broken, or the bearing is faulty.

This problem can be fixed by replacing the broken fan blades or faulty bearings. Ensure to hire a professional mechanic. 

Bad thermostat 

Another common heating problem with the Kia EV6 is a bad thermostat. When the thermostat is bad, it can cause different problems depending on whether the thermostat is stuck open or stuck closed. If it’s stuck open, it will make the engine run colder than usual and turn on the check engine light.

What’s more, a bad thermostat can cause poor fuel mileage and the heater to blow cool air. On the contrary, a thermostat that is stuck closed will cause the car to overheat. 

To resolve this issue, the owner will have to replace the bad thermostat with a new one. You should ensure to hire a professional mechanic to help you out. 

Bad heater blower motor resistor

A heater blower motor resistor is the part that controls the speed of the blower. So, if this part is going bad or failing, the heater won’t function properly. Nevertheless, if the heater blower motor fails, the A/C and heater may still function, but air may blow away from the vents at only some of the speed fan settings. And if it’s not fixed in time, the whole system may fail to work after some time. 

To fix this problem, you will have to replace the bad or failing heater blower motor resistor. 

Damaged heater core

One of the common signs of a failing or damaged heater core is when the engine starts to run hotter than usual. Besides, a failing heater core may make the car’s interior smell like engine coolant. What’s more, the smell may become even worse when the heater is switched on.

However, before replacing a bad heater core, you should find out if it’s damaged or clogged. If the heater core is clogged, then you will have to clean it and not replace it. You should replace the heater core if it’s damaged. 

Leaking coolant system 

Another thing to look at when you’re having heating issues with your Kia EV6 is the coolant system. A leaking coolant system can cause the engine to heat and other problems. In most cases, a leak is usually caused by a loose hose in the hose clamp. However, it can also be caused by a leaking cylinder head gasket. 

No matter the case, ensure to have a professional mechanic replace the faulty or bad part. 

Water leak

Even though water leakage is not very common in the Kia EV6, this is the last thing that you should experience if you have a failing car heater. If water leaks into the heating system, you will experience a ton of issues that may turn out to be costly. 

That’s why it is vital to always check your water pump and hoses. Regardless, you should replace all the damaged parts to avoid further damage to the heating system. 

Failing heater hose 

If you notice that the car smells of engine coolant under the hood, this is an indication that your heater hose is failing. Furthermore, if the coolant runs onto the heater core inlet or outlet, then the cabin may start to smell of coolant and mildew. 

To fix this issue, you should take your car to a professional mechanic and have the bad heater hose replaced. 


Why can’t I adjust the heater temperature?

If you cannot adjust the heater temperature, this is a sign that the heater control valve is failing. As a result, adjusting the temperature may not change the air temperature at the vents, whether cold or hot. Moreover, the valve could leak engine coolant, making the car overheat.

Note that this issue can be fixed by replacing the bad heater control valve. 

Why is the heat not working on my Kia EV6?

The main reasons why the Kia EV6 heater is not working on your car is due to a bad thermostat, a damaged heater blower motor, a failing heater blower motor resistor, a failing heater hose, or a leaking coolant system. 

Why is my car blowing but no heat is produced?

This can be caused by low coolant. It is also crucial to know that low coolant is either caused by water evaporation or a leak. Besides, no heat from the A/C or heater can also be caused by a clogged heater core that limits the flow of coolant. Fixing these issues will resolve the problem. 

Final thoughts 

The Kia EV6 is not only a fast and high-performance car, but it is also comfortable. Nonetheless, this compact crossover SUV also comes with multiple issues that interested buyers ought to know about. Some of the common heating problems that owners should be worried about are a bad thermostat, a failing heater blower motor, a leaking coolant system, a damaged heater core, and a failing heater hose. 

Note that with proper care and maintenance, most of the Kia EV6 heating issues can be avoided.
