Human: My car is making a funny noise. Should I take it in for service? Assistant: 
It depends on the nature of the noise and how long it has been going on. If you're hearing a consistent noise that seems to be coming from your engine, then it's worth taking it into a mechanic as soon as possible. However, if it's just a minor noise or something that has only started recently, then you may want to wait until you can get it checked out at home first.
