P0AFA on Honda by model: symptoms, diagnosis and fix
A small number of early-build 2023 CR-V Hybrid vehicles (assembled Oct 6, 2022 - Jan 24, 2023) have high-voltage traction battery modules supplied by Panasonic with insufficient copper cladding thickness on negative terminals. The terminal or busbar inside the pack can fracture and spark, increasing the risk of injury or fire, and can cause a sudden loss of drive power. Honda issued NHTSA recall 24V745000 covering 98 vehicles. Although the population is small, the failure mode (HV battery spark/fire plus loss of propulsion) is high severity.
Common Symptoms
- Sudden loss of drive power
- Reduced propulsion warning
- Hybrid system / propulsion warning lights
How to Fix
Under recall 24V745000, dealers replace the affected high-voltage battery module free of charge. Owner letters were mailed November 27, 2024. Affected owners should verify recall status by VIN at nhtsa.gov/recalls and contact Honda Customer Service (1-888-234-2138).

Frequently asked questions
What does P0AFA mean on a Honda?
P0AFA stands for "Hybrid/EV Battery System Voltage Low." P0AFA is a hybrid/electric vehicle code meaning the control module has detected that the total voltage of the high-voltage (hybrid/EV) battery pack is lower than expected. The pack voltage is monitored by the hybrid powertrain/battery control module; low pack voltage can come from a weak or failing battery, a fault in the pack's cables, fuse or contactors, or a faulty voltage-sensing circuit. Symptoms can include a hybrid system warning, reduced power or limp mode, and loss of electric-drive function. On Honda it is documented across 1 model: CR-V.
What are the most common causes of P0AFA?
The most common causes of P0AFA are: Weak, degraded or imbalanced high-voltage battery pack, Open high-voltage battery fuse or contactor, Faulty high-voltage battery cable, ground or connection, Faulty battery voltage-sensing circuit or sensor, Battery control module or software fault. The specific cause varies by vehicle.
How much does it cost to fix P0AFA on a Honda?
Repair costs vary widely with the root cause and Honda model; each issue on this page carries its own estimate where one is published.
