A defective AC compressor clutch assembly can cause excessive noise or vibration when the air conditioning is on. Improved parts are available. Replacing the faulty clutch assembly does not necessitate replacement of the complete AC compressor or evacuation and recharging of the air conditioning system.

The A/C blows cold air for a little while, then begins blowing outside air. It sometimes goes back to cold for a little bit, but always goes back to blowing outside air. I took it to be looked at & was told by my mechanic that it was a known problem with my Kia model year (Sportage, 2006). The clutch on the air compressor goes bad & that a lot of dealerships will replace the compressor, but not the clutch. This does not correct the problem though. Kia (where I currently am) has been giving me a hard time about it & said that they don't keep the product in stock & that it will take several days to get the part in. I don't have time... I am moving in 36 hours & need my car fixed now!

Constant whine, getting worse. Dealer said it is the A/C "hub" (basically the A/C clutch assembly) Warrenty covers the compressor - but not the "hub". Can't buy the "hub" or clutch assembly from local parts stores - they only sell the entire compresser (clutch included)and dealer wants over $500 to just replace the A/C "hub". Can't afford to get this fixed.

First it blew cold air, then outside air, then back to cold air, then stopped all together...mechanic says it is the a/c clutch coil... I really liked my Kia at first, but it seems there is always something happening to it, the gear shift lock release broke, I can't get it out of gear now without a pen to push the button in and out, but since it was so hot this summer I am choosing to fix the a/c first...not to mention other little things that seem to break...I personally will never buy another Kia, and when asked by others I will not recommend it either.

A/C just went out completely. A/C Clutch and Compressor.
My AC is switching on and off too! Blowing Cold then hot outside air! The first time this happened was at 70,000 miles. The compressor was replace in August of 2013. 11 months later the problem comes back. The dealer tells me it's not the compressor this time but the expansion valve and a leak in the high pressure hose. I wasted money to get this repair done as it did NOT fix anything. They refuse to help in any way at this point. I will most definitely not be buying anymore KIA's.

air compressor clutch is rattling and making noise. of coarse my warranty just expired at 5 years. I think if this is an ongoing problem (from what I have read) the company should recall it and fix it. hopefully the clutch can be replaced without replacing the entire compressor. ive been a kia sportage owner since they first came out, never had a problem until I bought the 2008 but was treated very poorly at the dealer. it was kind of yeah yeah yeah what do you want to us to fix, at full cost to you....no more good word of mouth compliments from me.....

whining noise, took to mechanic and told me AC compressor needs to be replaced. Seems like a common problem in this vehicle!! not happy with the repair cost!! luckily he charging $500 instead of $900 the dealer wants.
Same thing, a whining vibration when ac is on, even after a freon charge.

A/C quit working on our 2011 Kia Sportage. Was fairly abrupt. One moment the A/C was working fine, then the next moment it wasn't. Did that a few times. Now it doesn't work at all. We did not notice any odd noises associated with this failure. We checked the charge, thinking it could have leaked out. No. We should have seen around 40 psi on the low side while the A/C was running. Instead, the pressure was so high it was off the scale. I would expect to see that if the refrigerant was not circulating. Hearing that other people have experienced A/C clutch failures, seems likely that's what has happened to us. Because the car is just over 60,000 miles, the dealership will not fix this under warranty. They asked $113 just to diagnose the problem. If it is the A/C clutch, they ask an additional $475. Kia is not doing a recall either. I am not sure but it seems the clutch is integral. Only way to replace the clutch is to replace the entire compressor. Since summer is nearly over, what we are going to do is live without the A/C for now.

My 2011 Kia sportage a/c comes on sometimes and works fine, but then it won't engage and blows hot. While it was working I checked the pressures and they were low so we charged the system and it worked for two days then stopped again. clutch not engaging. We just purchased the vehicle from a reliable dealership but haven't gotten it repaired yet. It sounds like the clutch is failing but when it works it works great . Frustrated since the dealer is 80 miles away ,we can't just up and drive to them on a whim

Loss of master clutch, an expensive item, so had new rubbers fitted and the metal face ground. Still, the service mechanics continued to pour in clutch/brake fluid to eradicate air, but to no avail. After a day or two, back to not being able to engage 1st and 2nd gear and corrected this by pulling the clutch pedal up with my foot. So attached a spring to keep the tension on the pedal and hence no further problem.

Noise when air condition is on. Squeaky belt when start up

It has been going on for awhile now. AC doesn't kick on right away, I have to turn it on and off a few times and keep it on high. AC is cold for a little while or while on the highway but then gives outside air when going less than 40 mph.

Having the same issue with my air conditioning. Works fine for about a 40 minute drive, then just blows outside air. I contacted the local dealer in Wt Bear Lake, MN and they flat out told me that there were no known issues with Kia's air conditioning. Leaves an uneasy feeling having them do the repairs, if they are not honest. It's a little frustrating and upsetting to know the dealer is not honest in their business dealings.
