Owner complaint summary

While traveling at highway speeds, the vehicle suffered a sudden and total loss of motive power (high-speed stall) without prior symptoms. A "Charging System Fault" message appeared seconds before the engine and all critical electrical systems shut down. This failure occurred in active traffic, resulting in the immediate loss of power steering and electronic braking assistance, creating an imminent collision risk for the occupants and surrounding motorists. Component Failure: The authorized dealer confirmed the failure of the DC-DC Converter (original part LR176476), which regulates the 48V-to-12V charging cycle. The component is currently held by the dealer and available for inspection. The failure caused a secondary total depletion of the 12V battery, rendering the vehicle's safety lighting and hazard signals inoperable. Manufacturer Awareness: The dealer confirmed the original part has been discontinued and superseded by a revised design (Part 433123472) due to known defects. Furthermore, the dealer stated that multiple other vehicles are currently grounded at their location awaiting the same backordered safety component. There is currently no estimated time of arrival for the revised part, leaving the vehicle indefinitely sidelined due to a systemic manufacturing flaw.
