Hey, My OT has the exact same issue. Sounds like a compressor noise to me. It' happened like every 10s so I assume we're all facing the same issue. I sent my OT to dealer to have an inspection last week and they just told me it's normal and all GX they had have this sound. I doubt it but since I see you all have this issue... So it may tame times till Lexus know how to fix... I think this is related to the temperature as well. I first time noticed this sound in the last 2 week, when I'm in Texas, and recently, we got 100 degrees hot every day, and this sound is more noticeable than before. I really hope this sounds will disappear when the weather get cooler like under 85. But thanks guys it make me feel much better hearing I'm not
100% it is the seat AC fan. Turn off the climate concierge and auto seat fan option.Yes. I believe that it’s the seat AC. I never had ventilation on seats prior to this car so I wondered what that noise was as well. After turning off the seat AC the sound went away.
Well, I don't even realize this is an issue! I thought it only had seat bottom cooling, and my seat back was never cooling at all........As someone had mentioned above it could be related to the cooling function of the seats. Based off the above listed post it sounds like a supply line may have disconnected from the seat bottom or seat back (similar to the problem with the massage function of the seats). Can those who are having the problem confirm that the seat bottoms and backs on both your front seats are cooling when that function is on? Just a thought
Do you have this fixed with your dealer? Could you also help to point out the link to the MGM comments? I want to send it to my dealer and let them to have a look again.Just noticed MGM mentioned back in late July that it is a seat A/C line disconnecting and is a known problem by Lexus. It might be unique to the OT model as their supply lines may be different from those in the Luxury and Premium models due to how the vehicle A/C is sent to the rear of the vehicle.
It is on page one of this postWell, I don't even realize this is an issue! I thought it only had seat bottom cooling, and my seat back was never cooling at all........
But I still can hear the noise even when I turn off the seat cooling. I'll keep looking for a solution.
Correction it was MJM on page oneIt is on page one of this post
I haven't experienced this but notice my AC is always on. The "AC" button doesn't seem to turn it on or off if I have the temp at 68-70 which is odd based on my previous Lexus and Toyotas. Have you also noticed this?Not sure if anyone notices this but my when my AC is on every 15-20 seconds I can hear what sounds like an air line filling up or pressure being released. It is not super loud but can be heard above road noise and talk radio. Now that I hear it I cannot not hear it.
Before I take it back to dealer I just wondered if this was something that others have heard.
Thank s
