After driving for about 5 miles on the highway I will get a swishing water sound from below my passenger side dash when I come to a stop. There is no noise when cruising past 30MPH, but it may be getting masked by road noise.
Everything I'm reading on the Internet points to air pockets in the cooling system - in this case the heater core. I brought my car into the dealer to have the cooling system "burped" and was told that I was exaggerating the noise and I shouldn't be bothered by it! They told me that KIA would not pay for this service unless the noise got worse. This noise is driving me insane.
Has this type of problem ever happened to you?
Any suggestions on where to go from here?
Should I just do the procedure laid out in the Tech Manual on KGIS? The car is only 6 weeks old and I would think KIA should be responsible for this...
I may have the same noise as you. It is related to the A/C. Check and see if the noise goes away when you turn the A/C off (press the button twice in case it was on but wasn't showing you that it was on).
In my case the noise goes away when I turn off the A/C. The noise is worse sometimes than others. If can get so loud that it is embarrassing when I have anyone else in the car, and i shut the a/c off right away.
I have had 2 dealers check it out 3 times total, and they say it is normal for any car and it is the coolant passing through the expansion valve. This is NOT normal as I have never heard it in any other car with the A/C on, and trust me, I notice any little noise that shouldn't be there.
Sounds like some cars have this noise and some don't. Next time I go to have it checked and they say it is normal I am going to have them sit in a new one on the lot and prove to me that all the cars do it... if they do then there is a design flaw on this particular car.
The reason this one is really annoying for me is that my rio has auto climate control, which basically always turns on the A/C no matter what position, temperature, etc. If I set it to manual climate control, I still get the auto defog come on all the time, which reactivates the A/C. I can disable the auto defog but it enables itself each time I shut the car off, so I am constantly having to turn off A/C or disable auto defog logic.
The auto defog wouldn't bother me at all if the darn A/C didn't create such a racket!
We really do need to get to the bottom of this, if it weren't for this noise, I would feel so much better about my car, and feel a bit better about having passengers in it!
