Went in to the dealer for a clunking noise from the front end at low speeds on my 16 GT speed.
I was told it’s lower control arms.

The dealer also stated the coolant appeared discolored. Like a milkshake color and consistency. They will look further into it but has anyone experienced this before?

 

I'd say you just need a coolant change.

"True" milkshake (ie: oil in coolant) usually looks more frothy.

 

I had my coolant flushed about 14 months ago though

 

Stick a bit of paper towel in it to wick some of it up. Then see if the paper towel has any oil or gas smell.

 

It could be very possible that your oil cooler has failed and is leaking oil into the coolant
