Problem overview

Some Mazda CX-30 owners report experiencing issues with the automatic parking brake not staying engaged in Park, even after following the Owner's Manual instructions. This can lead to frustration as the parking brake may unexpectedly re-engage despite attempts to disengage it. Additionally, starting with the 2022 model, some owners have noted that the parking brake automatically disengages after shifting out of Park, which may not be the case for older models. Furthermore, those who have recently had their transmission replaced should be aware that this could affect the automatic parking brake's functionality. It is recommended that owners consult with a Mazda dealership or a qualified mechanic to effectively address these concerns and ensure vehicle safety.
