Ada Cook, from Ffestiniog, is charged with taking a car without consent and driving without a licence or insurance in Towyn on 27 January - and the same offences in Rhyl two days later.
She also failed to appear in Prestatyn magistrates court on 12 June.
District Judge Gwyn Jones said he issued the warrant "with regret".
A warrant has been issued for the arrest of an 88-year-old Gwynedd woman who failed to attend court on Friday accused of six motoring offences.
