AC Pressure Noise GX550 OT+

[WRB]

OT+ here. I took mine back to the dealership on Tuesday. In addition to the A/C noise I also had some loud squeaking brakes that I wanted to get looked at.

I got a call this afternoon saying that Lexus is aware of the noise and working on a solution to the problem. As for the breaks they are replacing the entire brake pads, calipers, etc. Ordering the parts and getting installed so happy about that.

Bad news here. I was hoping I don't have to hear these sounds when the weather cools down. It works for a while. But it starts again when it gets cold in my area. So now I know it happened for both below 70° and above 85° lol. Seems I need to get used to it this whole winter. Hope Lexus can get it fixed ASAP.

Did anyone get a resolution to this?

Taking mine in for the 5K service next week. Plan to ask and will report back. @WRB any update on your end?

I think the HVAC system is just pretty noisy generally, just “turn up the radio” as the horrible hair metal band, Autograph, said.

One really annoying thing is that the A/C button always defaults to “off” in my OT+. Is this the norm? First car I’ve ever owned where that is the case (and should not be). Is this reprogrammable?

I have this same issue. Following this thread. Turning off the passenger ventilated seat fixes it. I plan on taking my vehicle back to the dealer in a month for its 5k service where I'll bring this to their attention.

I tested this yesterday by manually turning off both seat ventilators (on auto I assume they run when hot out) and still hearing the A/C pressure hissing noise. Mine only goes away when I turn off the A/C completely.
