P0AFA on Jeep by model: symptoms, diagnosis and fix
NHTSA campaign 23V787000 covers certain 2021-2023 Jeep Wrangler plug-in hybrid vehicles whose high-voltage battery may fail internally and cause a fire while parked or driving. That campaign was replaced by 24V720000, which was then replaced by current campaign 25V741000. Vehicles previously repaired under the earlier campaigns may need the current remedy.
Common Symptoms
- High-voltage battery fire while parked or driving
How to Fix
Check the VIN for current campaign 25V741000 (FCA recall 68C). Until the current remedy is completed, park outside and away from structures and other vehicles and do not charge the vehicle. Dealers update the high-voltage battery software and replace the battery as necessary, free of charge.

Frequently asked questions
What does P0AFA mean on a Jeep?
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 Jeep it is documented across 1 model: Wrangler.
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 Jeep?
Repair costs vary widely with the root cause and Jeep model; each issue on this page carries its own estimate where one is published.
