What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationDue to a software anomaly, the BPCM may not correctly evaluate the battery State of Health (SOH) on some vehicles. This may result in charging limitations and/or an inaccurate estimate of the remaining driving range. These conditions may display incorrect information to the customer and affect the customer's perception of the vehicle's reliability. This service campaign is intended to ensure proper operation of the battery management system.
