Car breakdowns linked to the Body Control Module (BCM)—a vehicle’s onboard computer that manages functions such as lighting and door systems—are increasing and are now among the most common causes of roadside assistance, according to the AA. The outlet reports that BCM-related breakdowns have more than doubled since 2020.
The articles explain what the BCM is and why problems with it can lead to faults and failures across multiple car systems. While both sources focus on the same AA figures and the same definition of the BCM, they present the information from a consumer-information angle, encouraging drivers to understand the component. Neither source provides additional comparison to other specific breakdown categories beyond noting the BCM’s rise into the top five breakdown causes.
Overall, the shared emphasis is on the trend reported by the AA and on raising awareness among drivers about the role of the BCM in modern vehicles.
