Significant motor noise behind instrument cluster

[Maverik259]

Got a 2026 Tungsten. Noticed often after shutting down and I’m still in the truck that some significant motor cycling noises go on seemingly behind the instrument cluster/under the heads up display.

Any idea what’s under there?

Mine does the same thing. I heard it was the brake system cycling, but what do I know?

HVAC door actuators closing blend doors, setting the recirculate door to closed and opening the floor vents so outside air doesn't get in. My guess, to help with condensation and possibly dust but to seal the cabin from outside air. Seems like they started that in 23 or so as I've seen TRX people mention it

It's the new hydraulic braking system they started using in '25. After shutting off, it goes through a cycle and makes noise.

I have also read that the Hurricane trucks also have a small pump to circulate cooling for the turbos as well is working to coll the turbos to keep the oil/vanes from "cooking". So that may be what you are hearing; possibly your mileage may vary.

Thers that too but thats a very light humming sound, the noises behind the dash are louder and clicking. I can hear the door motors moving closing the blend doors on mine.
The Limited, RHO and Tungsten also have fans in the headlights that you may hear a very light hum from when they are on

The clicking and popping is the brake system. You can feel it in the pedal. The humming is almost impossible to hear in the cabin.

Ya it’s not that and usually don’t hear that inside. My bmw does this due to the hot V design those turbos really need the help cooling. I also had to make sure I let the EGT temps setting to below 800 before I shut her down. Luckily don’t see anything like these issues on the hurricane design. They even got some great heat shielding on them which didn’t come on my M5. Had to add some lava blankets and go catless to relieve the heat soak.
