122-B7U4T-052017-10-15. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Customer Concern: Certain vehicle systems have unwanted, unpredictable behavior. Technical Concern: The symptoms are difficult to diagnose. There may be multiple symptoms intermittently affecting multiple systems. Though this is not an exhaustive list, some common failure modes are: ? Start/stop issues ? Power windows not fully returning to the parked position after automatic preopening ? PCM audio stopping during a start/stop cycle Ultimately, the technician determines that low 12-volt battery voltage is the underlying root cause of the unwanted behavior. The technician corrects the battery?s low voltage. Consequently, the unwanted behavior ends.

The summaries are NHTSA's. Each bulletin's page links NHTSA's copy of the manufacturer's document.
