What P0A62 means
P0A62 signals overcurrent in phase V of drive motor A. Hyundai lists it in bulletin 17-01-057-1 for the 2017 Ioniq Hybrid next to P0A5F, P0A65 and the isolation fault P0AA6: the bulletin traces them to coolant leaking inside the traction motor and checks the high-voltage insulation first. Check Engine and hybrid lights came on, acceleration weakened and the air conditioning stopped. The dealer first runs an isolation breakdown test with the scan tool, then checks the motor for coolant and replaces it if needed. A shorted turn or a damaged phase lead to ground gives the same picture on other vehicles. A Hyundai patent describes two measured phases with the third calculated. P0A61 is the low side, P0A60 the general V code, P0A5F and P0A65 phases U and W.
P0A62 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor1.5 to 10 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0A62
- Check Engine and hybrid warning lights
- Weak acceleration, air conditioning inoperative
Common causes of P0A62
- Most likelyCoolant inside the traction motor with loss of insulation (Hyundai Ioniq Hybrid)
- PossiblePhase V lead or winding shorted to ground or to another phase
- PossibleInverter power stage fault in phase V
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0A62 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| A | Area: hybrid propulsion. |
| 62 | The exact fault in that area. |
What to do next
- Note P0A62 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0A62
What does P0A62 mean?
P0A62 means "Drive Motor A Phase V Current High". P0A62 signals overcurrent in phase V of drive motor A. It is a generic code, so it means the same on every make.
Is it safe to drive with P0A62?
Drive gently and only to a workshop. With P0A62 the car can go into limp mode (reduced power) to protect itself.
Will P0A62 fail an emissions test?
Yes, it can. P0A62 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0A62 to fix?
Difficulty: workshop only. A typical repair takes 1.5 to 10 hours of work. This is a job for a workshop.
Will P0A62 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
