Is your jurisdiction in the United States? If so, that's not true. You may automatically have your license revoked if you refuse a breathalyzer and a field sobriety test. But that's different than committing a felony. Your penalties may be harsher if you are eventually be found guilty of DUI without the breathalyzer evidence, but that is not being charged with a felony.

You absolutely have the 5th Amendment right to not incriminate yourself in every jurisdiction of the US. There are automatic consequences to refusing a breathalyzer (losing ones license), but they have nothing to do with being charged with a crime, much less a felony.
