The vehicle has failed three times in approximately 30 days.  First failure, June 26, 2026: the vehicle would not start. Numerous fault codes were stored across multiple modules, including P0562 (system voltage low). The odometer display was flashing, indicating a module had dropped off the communication bus.  Second failure, July 13, 2026: less than 48 hours after returning from a road trip and parking, the same condition recurred. The vehicle required external 12-volt power to start.  Third failure, July 26, 2026: a brand-new AGM battery had been installed on July 24, 2026. Within 48 hours of installation the battery measured 5.85 volts — fully discharged. An 80Ah battery discharging in 48 hours indicates a continuous parasitic draw of roughly one amp, which is 20 to 40 times the normal key-off draw for a sleeping vehicle.  Owner testing has ruled out both the battery and the charging system. The DC-DC converter was measured delivering 127 amps at 13.9 volts, confirming it functions. The replacement battery accepts and holds a full charge, resting at 13.06 volts after recharge. The previous battery passed a printed conductance and load test.  During each failure, the entire camera system and the ParkSense park assist system drop out simultaneously and the odometer flashes. Stored codes include U0159-00 (lost communication with parking assist control module) and B2204-00 (ECU configuration mismatch). Separately, and even when the 12-volt system is healthy, the rear backup camera intermittently fails to activate at startup and sometimes only begins working after 5 to 10 minutes of driving.  Safety concerns:  1. Rear visibility. The backup camera intermittently does not display an image when the vehicle is placed in reverse.  2. Loss of motive power.  3.
