The vehicle experienced repeated high-voltage system warnings and battery conditioning system failures. On multiple occasions the “Service High Voltage System” message appeared along with codes P0530 and P1C26 related to the lithium-ion battery conditioning system that controls heating and cooling of the high-voltage battery pack. A critical U3578 code triggered an urgent OnStar alert requiring immediate service. The high-voltage fault was linked to an overcharged HVAC system that caused the A/C compressor to fail. This led to a full HVAC system replacement, radio/infotainment failure, and multiple module reprogrammings. The vehicle could not charge past approximately 65% and showed a red 12-volt battery light after charging. Burning electrical smells were present during some incidents. Warning lights and messages appeared repeatedly and were confirmed by OnStar diagnostics on April 28, May 6, May 19, and June 16, 2026. The dealer performed warranty repairs including compressor and HVAC replacement per TSB 25-NA-130, yet the same high-voltage and battery conditioning faults returned. The problem has been reproduced and documented by the dealer and OnStar. These defects affect critical high-voltage battery thermal management and electrical systems. They create risks of sudden power loss, inability to charge, reduced drivability, and potential safety hazards. The vehicle has been out of service for extended periods and is currently parked due to ongoing safety concerns. The manufacturer was notified through warranty claims and EV Concierge case #95412771 but has not permanently resolved the defect. The failed components (high-voltage battery conditioning system, HVAC compressor, and related modules) are available for inspection upon request.
