Hey all. I have a 2022 SEL convenience hybrid tucson and today when I was driving it randomly threw an alert to check the cruise control then another to check the front crash system. After that the ac started swapping to outside air rather than in cabin circulation. When I turned the car off the warnings went away but it's still doing the ac thing every few minutes. I'm pretty frustrated and not sure what is wrong. Think this so something I can reset myself or it's gotta go in to the shop? I've had it 2 months and it's got 2500 miles :/

My car does this as well, and it is super frustrating. My entire cooling system on my air conditioner went out at 250 miles, so I currently have zero air. All of this at 350 miles, with no end in sight of getting it repaired.

Did you take it in? I'm on part #3 and should hopefully be picking it up this weekend after A MONTH in the shop. If you are having issues too I wonder if it's a manufacture thing.

I took it into the shop, they advised the machine that diagnoses the air conditioning problems is broken, and the part they need to fix the machine will not arrive for at least 4 to 5 MONTHS. I asked if I could take it to another dealership ( the next closest one is an hour away) , they laughed and said that I would be lucky to get an appointment in another service department in 2 to 3 months. I am beyond pissed at this point, to be driving a brand new car with major problems from the get go, the service department is zero help, so I have requested a meeting with the GM of the dealership.

Take it to a different dealer for sure. It took 3 weeks to get the initial part then they needed 2 more parts. Hoping this last one is it for the car and jts fixed. They have had it almost as long as I have owned the car at this point. If it's not fixed I'm having them replace the car. They should at least order the part abd get you in loaner for the time being. Mine has me in a rental. The dealer closer to me was gonna make me pay for all the work. I called the dealer that I bought it from (2hrs away) and they are covering it all and have been great so the drive is worth it. It should be under warranty so you need to push on them or find a different dealer. What state are you in? And is your SEL convenience too?

I am in Alabama, the other dealerships are an hour away in wither direction of me. My husband drives a company car that we cannot use for personal use, so this is basically our only car. If they do not offer me a loaner car, which they have not, then I cannot leave it at another dealership without something to drive. They told me the other service centers were not taking in any new appointments for 2 to 3 months. I honestly think it is their responsibility to get it to a service center that can fix it, or in the least get me an appointment with one.
Mine is a 2022 Limited.

I feel like they are trying to scare you. Definitely take it somewhere else. That seems shady to me. I'll keep you posted on what happens. It's been a relay, cruise control system/radar and the front camera

Good luck, and please keep me updated. I have had to use the lemon law before, years ago, and hope I don't have to in this situation. It looks like you have the lemon law on your side, your car just has to be in the shop a total of 30 days to qualify.

The Tucson monitors air quality outside. When it detects bad air it will close outside air from coming in to the cabin

I believe it also does this as part of the auto window defog when the humidity in the cabin is detected to be high. The system will switch to outside air for a bit until the humidity comes down and then switch back. It's a setting in the climate control options you can turn off.

Yes, however I always keep mine on inside air so it's toggling TO outside air. There was a hole in the hybrid relay that appeared to cause this. They "fixed" it but it happened again so I'm talking with the dealer

From the owner's manual, this is what I was referring to:

Auto dehumidify (if equipped)
To increase cabin air quality and reduce
windshield misting, recirculation mode
switches off automatically after about 5
to 30 minutes, depending on the outside
temperature, and the air intake will
change to fresh mode.

Turning Auto Dehumidify ON or OFF

Climate control system
To turn the Auto Dehumidify feature
on or off, select Face level ( ) mode
and press the air intake control ( )
button at least five times within three
seconds. When Auto Dehumidify is
turned on, the air intake control button
indicator will blink 6 times. When turned
off, the indicator will blink 3 times.

Infotainment system
Auto Dehumidify can be turned on and
off by selecting ‘Setup → Vehicle Settings
→ Climate → Automatic Ventilation →
Auto Dehumidify’ from the infotainment
system screen.

It doesn't do that. It was a constant toggle and lights dimming. Not expected behavior. It was almost 7k worth or repairs that were needed

Got it. Thanks for clarifying. I didn't see any mention of the dimming lights in here so apologies for that. Yeah this is definitely not the auto dehumidify if the lights were also dimming with it.

No worries at all :) it slowly got worse before I got it into the shop. It was there 37 days 🙄 the cruise control system, radar, camera and the hybrid hole were all what was wrong (so far)

Mine is switching from recirculating to outside air. I don’t like it. Thanks for posting this. I will try to turn this off. 👍
