Why This Recall Matters

FCA US LLC has identified that certain 2018-2022 Jeep Wrangler and 2020-2022 Jeep Gladiator vehicles may not comply with OBD II regulations due to an issue with the Malfunction Indicator Lamp (MIL). The MIL, also known as the Check Engine Light, is a critical component of your vehicle's emissions system. Its primary function is to alert you to potential emission-related problems that could affect your vehicle's performance or the environment.

If the MIL is inoperable, drivers would not receive a warning if an emission issue occurs. This means a problem could go undetected, potentially leading to increased emissions or other vehicle malfunctions without the driver's knowledge. This Emission Recall 16C ensures that your vehicle's emission monitoring system functions as intended, providing crucial alerts for necessary maintenance.

What's Being Recalled

This Emission Recall 16C addresses an issue with the instrument panel cluster (IPC) in approximately 32,587 affected vehicles. The defect involves an inoperable Check Engine/Malfunction Indicator Lamp (CEL/MIL). The recall applies to:

2018-2022 Jeep Wrangler (JL)
2020-2022 Jeep Gladiator (JT)

The core problem is that the MIL may not illuminate when required, preventing the driver from being notified of an emission system fault. For some 2020-2022 Jeep Gladiator (JT) vehicles, the CEL/MIL and cargo lamp indicator functions might even be swapped. For 2018-2022 Jeep Wrangler (JL) vehicles, the CEL/MIL simply may not turn on at all. While the MIL itself does not directly affect emissions, its failure to illuminate means that any underlying emission issue would go unnoticed, making the vehicle non-compliant with OBD II regulations.

Symptoms You Might Notice

The primary symptom of this recall is an inoperable Check Engine/Malfunction Indicator Lamp (CEL/MIL). For 2018-2022 Jeep Wrangler (JL) vehicles, the CEL/MIL will not turn on at all during the normal bulb check. For 2020-2022 Jeep Gladiator (JT) vehicles, the CEL/MIL and cargo lamp indicator function may be swapped, or the MIL may not illuminate as expected. This means that if an emission issue requiring the MIL to illuminate were to occur, the customer would not be alerted, and the vehicle would be non-compliant with OBD II regulations. If you notice your Jeep Wrangler MIL not illuminating during startup, this recall may apply to your vehicle.
