There are several comments about the Sonata LX a/c climate control; however, I have not seen any discussions on the air quality control system which is a part of the auto air conditioning system. If you read the owner's manual for the 2006 model, page 109, and for the 2007 model, page 111, you will see that the AQS should only automatically switch to recirculating inside air in the presence of exhaust gas (or heavy smog). It should not randomly switch to recirculating when no exhaust gas is present. Other inconsistencies which Hyundai Motor America claims to be "normal" that we and the regional service manager have experienced is as follows: At times, the system doesn't switch over to recirculating in the presence of exhaust gas; at other times it randomly recirculates for no reason at all and will stay on reciruclating for several miles; often switches to recirculating when going under freeway underpasses; and our Sonata and a test drive by the dealer's service manager of a 2007 model both always switched when entering a garage. I could go on and on with many more incidences. My 2006 Sonata performed perfectly for ten months, then became erratic, recirculating 80% of the time. The dealer replaced the sensor which slowed down the reciruclating but has not resolved the problem. Hyundai claims that the random recirculation is normal regardless of what the owner's manual says. The dealer's service manager, after test driving two 2007 models, has experienced these inconsistencies and states that he doesn't understand the purpose of the system, since it does not perform as described in the owner's manual. Hyundai refuses to admit to any problem, and we are heading toward arbitration. Also, I am preparing two complaints to be filed with the State Attorney General's office over this issue and the sloshing fuel tank. I urge you to read your owner's manual and observe how your AQS system is operating. By the way, the air quality in this part of our state is relatively free of smog, so the system should not be recirculating unless it's exposed to exhaust gas.

Replying to: cabby (Jul 24, 2007 12:11 am) Because it was on Auto, you activated one of those 3 controls (see my earlier reply) to gain manual control (just for this control, ex: fan speed), the Auto text is no longer displayed on the LCD, BUT, the other 2 controls (AC and recirculation) are still in Auto. It remembers the setting on next engine restart. In this example, no Auto message on the LCD, but AC and recirculation are still in Auto mode. Just press the Auto knob to put the system into a known state, which is auto. Or shut it off and do not activate the Auto mode, manually activate the desired controls. |

I don't currently own a Sonata with this feature. 2.I don't really know how it actually functions (from a technical standpoint) so I don't know what "triggers" it to automatically use recirculate mode. I am assuming it is some type of sensor but what exactly does this sensor have to sense??? What components in "smog" or exhaust gasses does it need to see? If yours seems to have worked automatically for a long time frame I guess it does work. So, with these provisions out of the way my comments then: You don't see any discussion of this feature because it isn't of great concern to most who post here. It either works unobserved or doesn't and most don't care. I understand your special circumstances (wifes illness or circumstance) but guess what...cars have had (for years and years)a switch or button that can switch between recirculated air and outside air. If you detect something she doesn't like in the form of an odor or particular substance simply reach over and manually make the change to recirculate then when the crisis passes change back to fresh or outside air. Problem solved WITHOUT yet another lawsuit or arbitration trail. Yeah, I understand because Hyundai states it (this feature) exists it should work but whatever sensor drives the system apparently isn't ready for prime time. For my part this feature would be one of those "nice but never used" things like "Shiftronic". Admittedly none in our family has a breathing problem but I have NEVER switched to recirculate mode on ANY of our AC equipped cars for any reason. As for the "gas sloshing" problem?? I personally feel you are much too picky and much too quick to file legal recourse for non-problems (in the case of gas slosh) to minor annoyances (auto recirculate) in as much as this can be accomplishes manually. This is simply my take on your commentary. In the meantime I will try to educate myself on how this system works. |
