2022-2025 Stellantis USB/Media Hub Battery Drain TSB

Stellantis has issued Technical Service Bulletin (TSB) S228A000017 Rev. A, released in September 2024, to address concerns about a suspected Stellantis USB battery drain or power draw from USB ports and Media Hubs in various 2022-2025 models. This communication aims to clarify the normal operation of these components, which may be mistaken for a fault.

Symptoms of Suspected Battery Drain

Owners might notice that their vehicle's USB ports or Media Hubs continue to supply power to connected devices, or that associated LED lights remain illuminated, even after the ignition has been turned off. This observation can lead to concerns about a potential battery drain, as the vehicle appears to still be drawing current.

Understanding the "Active Charge" Feature

The TSB explains that many Media Hubs and USB ports in Stellantis vehicles are equipped with an "active charge" feature. This design allows the USB to remain powered on and provide current to connected devices for up to 60 minutes after the ignition is switched off. During this period, the LEDs associated with these ports will also stay illuminated.

This functionality is by design and is intended to allow for continued charging or power supply for a limited time after the vehicle is shut down. Therefore, any power draw observed within this 60-minute window is considered normal operation and does not indicate a fault or a true Stellantis USB battery drain condition.

Diagnosis and What Technicians Should Know

For technicians investigating a suspected Stellantis USB battery drain originating from the USB or Media Hub, TSB S228A000017 Rev. A advises a specific diagnostic approach. If a battery drain is suspected, the condition should be validated or retested after more than 60 minutes have passed since the ignition was turned off. If the power draw ceases after this 60-minute period, it confirms that the observed behavior is due to the normal "active charge" feature and not an actual battery drain.

This clarification is crucial to prevent misdiagnosis and unnecessary repairs, ensuring that technicians understand the intended operation of these electrical components.

Important Clarification for Owners

It is important for owners to understand that if their USB ports or Media Hubs remain active for a period up to 60 minutes after the ignition is off, this is likely normal behavior due to the "active charge" feature. This TSB helps distinguish between a designed operational characteristic and an actual electrical fault. If you observe power draw beyond the 60-minute mark, then further investigation may be warranted.
