P0C01: Drive Motor A Current High
What to do
As P0BFF, and check the mechanical possibilities first — a dragging brake or failing bearing is cheap, common, and makes the motor draw exactly this. If the car has felt slower, run warmer or lost range with no other explanation, say so.
What this code means
Drive motor A is drawing more current than the commanded torque explains.
High is the direction that costs something while it continues, because current makes heat everywhere it flows. The suspects are the ones at P0BFF with the short-circuit and mechanical-drag halves emphasised: insulation breaking down between windings lets current circulate without producing torque, and a mechanical load nobody accounted for — a dragging brake, a seizing bearing — makes the motor work harder for the same road speed.
The mechanical possibility is the cheap one and the only one that damages something else while it is ignored, so it goes first.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
