High Pitched Fan Noise

[Rei]

Hello,

I took delivery of my 2021 Gladiator last, last Saturday. I love it.

The only thing that seemed off to me was that when its fan is on at level 1-3, it's perfectly fine. However, when I reach level 4 and above, I hear a high pitched fan noise that reminds me of birds chirping.

Has anyone experienced this on their Gladiators? Is it normal?

Here's a link to a video with the noise.

@JeepCares , may I please ask if you've encountered any issue like this before?

Thank you everyone

The only thing I'm hearing is the wind whistling slightly coming out of the vents at the higher fan speeds.

My fan is fine at all levels except on level 2. It makes a high pitched noise.

Does your gladiator make a whistling sound like that, too?

Ah, mine is 4 and above. I'm really hoping I'm overthinking it and it's benign. Have you ever gotten your Gladiator inspected?

No. I just skip 2nd level fan. When it gets comfortable I set it to auto.

Dunno...
I've never paid that much attention to it.
That's what your video sounds like to me.

Half of the folks I've asked to listen to the video said the same thing.

I'm coming from a Dodge Challenger, and I'm not used to sounds of a Jeep.

If it's okay with you, if you don't mind, please listen for that sound in your Gladiator tomorrow? Sorry to ask; I just don't have a proper frame of reference.

Looking into a bit more today, I realize it might not even be the fan. As I increase the strength of the fan, the sound becomes more prominent, and its frequency sounds like it's increasing. I

t still sounds like birds chirping.

I recorded it twice under the Gladiator's steering wheel, next to the accelerator, where the sound seemed louder.

If possible, can you guys please check your Gladiators if they experience something similar?
