Hello, thank you for writing in. This is going to be a process of elimination. To start, the charging system may be having issues with the battery or the alternator. Both should be tested to make sure they are working correctly. While it is rare that new parts come faulty, it is not impossible. The battery may also be having issues holding a charge. All the connections from the alternator to the battery need to be clean, dry, and tight. If both pass their tests, then you may have something pulling extra power from the vehicle. Tests for a parasitic draw can be done with the vehicle off and while running. For help with further testing, contact our service department to schedule an appointment.
