The service department at the dealer we bought our most recent car from has a list of names and descriptions of various sounds that cars make when they need servicing. Every time I read it, I'm unsure whether it was always intended to be serious, or whether there was some irony involved in creating it.
I offered an addition that I encountered on the internet - when the power steering fluid in a 2005 PT Cruiser is too low, the mechanism sounds like the groaning sound made by Chewbacca in the Star Wars series.
That happened to my wife's car, and that is how it sounds!
