Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you.. this is most likely being caused by a failure of the electronic parking brake unit itself. it is sending an erroneous signal that it is engaged when it is not. You will need to replace the unit to rectify. Please let me know if you have further questions.
