The invention relates to a method for controlling a hybrid powertrain (10) of a motor vehicle comprising: - a combustion engine (11) associated with an alternator-starter (17) constituting a default starting member of the combustion engine (11); and - a rotary electric machine (12); - a gearbox (13) comprising at least one clutch (K1, K2) for changing gear, the gearbox (13) comprising an input shaft (13.1) to which the rotary electric machine (12) is mechanically connected and an output shaft (13.2) that is connected to the wheels of the motor vehicle; - a clutch (KO) for connecting and disconnecting the combustion engine, characterised in that the method comprises: - a step of detecting a malfunctioning state in which the combustion engine (11) is at a standstill and the clutch (KO) for connecting and disconnecting the combustion engine (11) is locked in the closed state; - a step of reconfiguring the starting member in which the alternator-starter (17) is abandoned in favour of the rotary electric machine (12); - a step of opening the clutch for changing gear (K1, K2); and - a step of controlling the rotary electric machine (12) to start the combustion engine (11).
