2021-2022 Stellantis Battery Drain Concern TSB

Owners of various 2021-2022 Stellantis vehicles, including the 2022 Alfa Romeo Stelvio, may experience issues related to battery drain. This concern is addressed in a manufacturer communication, NHTSA ID 10229041, which identifies specific conditions that can contribute to the depletion of the 12V/24V/48V battery system.

This bulletin aims to clarify potential causes for battery drain, helping technicians and owners understand why their vehicle's battery might be losing charge, even when the vehicle appears to be off. The information is crucial for diagnosing and addressing a 2022 Alfa Romeo Stelvio battery drain concern effectively.

Symptoms of Battery Drain

Owners might notice their vehicle's battery losing charge over time, leading to difficulty starting the engine or the need for frequent jump-starts. The manufacturer communication specifically points to two main conditions that can contribute to this battery drain:

• Dual USB Port Normal Operational Draw: The vehicle's dual USB ports may have a normal, expected electrical draw even when the vehicle is not in active use. This continuous draw, though small, can accumulate over extended periods, leading to battery depletion.
• Extended Illumination Or Extended Operation After Key Off: Certain electrical components, such as interior lights or infotainment systems, might remain illuminated or operational for a longer duration than expected after the ignition is turned off. This extended activity can also contribute to the overall battery drain.

Understanding Normal Electrical Draw

It's important for owners to understand that not all battery drain indicates a fault. The manufacturer communication highlights that a "Dual USB Port Normal Operational Draw" is an expected characteristic. This means a certain level of power consumption from these ports is normal, even when the vehicle is parked. Similarly, "Extended Illumination Or Extended Operation After Key Off" refers to systems that might stay active for a short period after the vehicle is shut down, which is also part of normal operation for some features.

However, if the battery drain is excessive or leads to frequent non-starts, it may indicate an underlying issue beyond these normal operational characteristics. Addressing a 2022 Alfa Romeo Stelvio battery drain concern requires distinguishing between normal power consumption and abnormal electrical faults.

What Owners Should Do

If you own a 2021-2022 Alfa Romeo Stelvio, Dodge, Jeep, or RAM vehicle and are experiencing persistent battery drain issues, it is recommended to have your vehicle inspected by a qualified service technician. They can perform diagnostic tests to determine if the battery drain is within normal operating parameters as described by the manufacturer communication, or if it points to a fault in the ELECTRICAL SYSTEM:12V/24V/48V BATTERY component.

Understanding the conditions like "Dual USB Port Normal Operational Draw" and "Extended Illumination Or Extended Operation After Key Off" can help owners communicate more effectively with service centers about their 2022 Alfa Romeo Stelvio battery drain concern.
