NHTSA Complaint #11710417 — 2022 LAND ROVER DISCOVERY

Car displayed a warning noting of an “an electrical fault” but was still running fine otherwise. Drove straight to service center roughly 5 miles away. About a half a mile away from service center the car experienced a cascading number faults in quick succession. First it was safety systems, then air suspension, followed by transmission and finally steering, which point the car was able to roll and some steering though required significant effort. This occurred during traffic, where luckily i had just gotten off the highway. I was able to coast the car into the middle of a shopping center parking lot where it became immobile. A fortunate timing of intersection traffic lights being green likely helped avoid a collision or hitting a pedestrian as all vehicle systems shut down. Towed vehicle to factory service center. Dealer confirmed a a failed DC-to-DC Converter (48V to 12V in mild hybrid system) led to vehicle shutdown and damaged auxiliary 12V battery. Requires a new DC to DC converter but is on backorder for weeks with no ETA available. Car remains immobile until a new part is received.
