Multi-System Faults: Cooling Fan Control Circuit, Battery Under-Voltage, A/C High Pressure Sensor, and Stereo AUX Input

Multi-System (Engine Cooling / Electrical-Charging / HVAC / Infotainment) · severity: Mixed - real severity varies significantly by which of the four codes is actually active: cooling fan (P0480) and under-voltage (00446) are genuinely important to address (overheating risk and broader electrical-system reliability risk respectively); A/C pressure sensor (00819) affects comfort/climate-control function only; AUX input (03138) is a trivial, cosmetic infotainment fault with no safety or reliability implication at all. · confidence: 75/100 · 3 cited sources

The specific fault codes and inspection steps to check before you buy, a full repair-cost estimate, TSB/recall reference, and the buyer negotiation tip for this issue are included in the R99 vehicle report.
