P0A80 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 P0A80 mean on a Jeep?
P0A80 stands for "Replace Hybrid Battery Pack." This code appears on hybrid and some electric vehicles and is a direct instruction that the high-voltage hybrid/traction battery pack needs to be replaced because one or more cells or modules have degraded beyond the system's acceptable limits. The battery management system continuously monitors each module's voltage, temperature, and capacity, and when the cells fall too far out of balance or lose too much capacity, it sets this code. You may notice reduced fuel economy, less electric assist, a flashing dashboard battery warning, or the vehicle entering a reduced-power mode. While the code names battery replacement, the true cause is often just one or a few weak modules rather than the whole pack. On Jeep it is documented across 1 model: Wrangler.
What are the most common causes of P0A80?
The most common causes of P0A80 are: Aged or degraded hybrid battery cells/modules losing capacity, One or more weak modules causing cell imbalance, Internal cell resistance increase from heat and age, Poor battery pack cooling (clogged fan/filter, weak coolant pump), Corroded or loose high-voltage bus bar connections, Faulty battery module temperature or voltage sensor, Failed battery management/ECU module misreading cells (less common). The specific cause varies by vehicle.
How much does it cost to fix P0A80 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.
