Turn off the lights (needs an object) vs. the car broke down (never takes one) — every phrasal verb is either transitive or intransitive.
What you'll learn
Just like ordinary verbs, phrasal verbs can be transitive (needing an object to complete the sentence) or intransitive (complete without one). This is a separate question from whether the phrasal verb happens to be separable.
An intransitive phrasal verb describes something happening to the subject itself, with nothing following it. Trying to add an object to one of these verbs produces an ungrammatical sentence.
Some phrasal verbs can be used both transitively and intransitively, often with a related but slightly different meaning — the transitive version usually means 'cause someone/something to do the intransitive action'.
go off (meaning to make a sudden loud noise) is intransitive — it never takes a direct object.
turn off is transitive here — it needs an object to say what should be turned off.
"My car broke down again this morning."
"That's the third time this month! Did you turn it off and try restarting it?"
"Yeah, nothing worked. I had to call a mechanic to pick it up."
"Ugh, that's so frustrating. Hopefully he can sort out the problem quickly."
