THC alert popping up in 2017 Model X

[Babayagawick85]

So my wife just got a used MX last week. We washed it earlier today, and now there’s this THC service alert popping up on the dash in service mode only. User text states that the Cabin Climate Control needs service, weird since the AC is working fine. Any idea what’s going on and how we can get rid of this alert?

Try restarting your car first, maybe the message will be gone.

There just might be an issue with the air intake since it’s located deep in the dashboard. For a 2016 model, it could be accessible just behind the center MCU display. You can have that area looked at, especially since you’ve just washed the car and that might have caused some moisture to interfere with the sensors.
