2019 Redline 6K miles spraying ATF on hood

Took the car in for the first free oil change and tire rotation and the mechanic told the wife that there's a bad leak. Mostly spraying up under the hood with no apparent source. The mechanic couldn't find the source, and late Friday afternoon there wasn't time to do much more than a cursory check on a lift. The mechanics at the dealership had never seen anything like this before and they weren't even sure it was ATF. The car had no symptoms and has driven very well. We are pleased with the Redline so far.
The dealership gave us a 2020 Trax - which makes me like the Redline even more.

Anyone have any idea what we are looking at?

I couldn't make a guess without seeing this first hand; but am very interested in the diagnosis and solution, as I have the same model with about 9,300 miles.

Fluid under the hood could be an oil line that feeds the turbo, but that would be engine oil and not ATF.

Is yours a FWD, or an AWD model?

Please share the outcome of this issue with us!

It's a AWD with the 9 speed transmission and the 2.0 motor. I will post updates as I hear. I assume this vehicle has electric power steering so the power steering can be ruled out.

That could be a mess, what ever type of fluid it is could degrade other materials (hoses, wires, connectors) under the hood leading to future issues. They need to be sure to clean everything.

If no leak can be located on any of the mechanical components, it could be that a critter was in the engine compartment and got caught in the serpentine belt, spraying on the underside of the hood with...

This actually happened to me one time. Spray pattern on the underside of the hood, little bits and pieces of what I guess used to be a rat. Guessing on the critter based on a couple of 3/4" long turds on top of the battery (which was adjacent to the serpentine belt on that vehicle).

Correct. Car has a BOSCH electronic assist power steering rack.

Like @garbec01 mentioned, maybe a loose hose/fitting to trans cooler/radiator.

The dealership called this afternoon and feels certain the red fluid was rust proofing that was done on the car a week earlier. Rust Check is the process I had applied a week earlier. The application is oil based unlike fluid film. I'm not sure why the underside of the hood had so much applied - we had no dripping or spots on the ground where the car was parked.

I am very pleased with this car this far.
