1. What does P0024 mean?
For 2019–2021 Subaru Crosstrek vehicles in the US, verified evidence links P0024 to a Subaru service-manual update. The available evidence does not establish a vehicle fault meaning, symptoms, drivability, charging status, or a repair for P0024.

The verified NHTSA manufacturer communication states that, for 2021 Impreza/Crosstrek diagnostics, steps were added to the diagnostic procedures for P0011, P0014, P0021, and P0024. The same communication also references a separate P-HEV drive-motor diagnostic procedure for DTC P1CCC96. The evidence does not establish that P0024 itself is a hybrid-drive-motor code or that the supplied canonical title is a technical definition of P0024.
