Intermittent Charging System Anomaly on a 2011 Kia Sedona EX
This technical case study details the advanced diagnosis of a persistent, intermittent charging system failure and stalling anomaly on a 2011 Kia Sedona EX (3.5L V6). After multiple failed alternator and battery replacements, the focus shifts to finding elusive high-resistance faults in terminations, grounds, and control relays. The guide outlines a precise diagnostic strategy utilizing Thermal Imaging (TI) and specialized electrical testing to pinpoint the true cause of the chronic electrical failure.
