Your car's battery died twice, requiring towing both times, and the key fob stopped working. Your engine overheated without warning, and now all your headlights, back lights, and brake lights have stopped working—making the car unsafe to drive. The right front light appears to have an electrical short. A dealer visit will likely be needed to diagnose the electrical system, test the battery and alternator, and repair or replace the faulty wiring and lighting components.

Your 2021 Kia Sportage was stolen shortly after purchase and later recovered by insurance. When the repair shop inspected the engine, they discovered a blockage that the insurance adjuster believes may be a manufacturer defect rather than theft-related damage. Your insurance claim was initially denied based on this finding, though the engine only had 27,000 miles at the time of discovery. The repair will likely involve diagnosing and clearing the engine blockage to restore normal operation.
