The turbos don't work properly - is correct

Turbo's (as in a proper noun, ie, the name of a car) exhausts are too noisy - is correct.

Turbo's were invented by the Japanese - is in fact technically correct (but would not be a common usage), because it's an abbreviation of turbochargers.

The other statements are incorrect due to the use of the apostrophes.

Also, it's punctuation, not grammar.

Thank-you.
