This is my second NHTSA complaint regarding this vehicle and manufacturer. Primary Safety Concern \u2014 Engine Wiring Harness: During a recent engine replacement at an authorized Hyundai dealership, technicians identified damage to the engine wiring harness and documented in writing that the owner \u201cmight have issues with drive ability.\u201d The dealership declined to repair it under the same goodwill program used to replace the engine and returned the vehicle with this known defect unresolved. The harness directly controls engine operation, hybrid system communication, and overall vehicle control. On a hybrid vehicle, a compromised harness presents a serious and ongoing safety risk. This component is available for inspection upon request. Engine Failure: The hybrid system warning light appeared prior to failure. The vehicle was towed to an authorized dealership where diagnostic code P1326 confirmed engine failure. The manufacturer acknowledged this and replaced the engine under goodwill. Additional System Failures: A pre-scan diagnostic revealed simultaneous fault codes across six systems \u2014 engine, transmission, ABS, active hydraulic booster, battery management, and motor control unit \u2014 including codes U0293 and U1004 indicating lost communication with the hybrid powertrain control module across multiple systems simultaneously. Independent Safety Advisory: A separate independent repair facility documented in writing that the vehicle presented a severe wheel hub bearing noise and formally advised of an extremely dangerous driving condition. Prior NHTSA Complaint: My first complaint to NHTSA involved this same vehicle when the manufacturer refused to provide a loaner during an extended recall-related repair hold, requiring formal escalation before they complied. The wiring harness defect remains unrepaired. The vehicle is driven daily out of necessity.","products":[{"type":"Vehicle","productYear":"2012","productMake":"HYUNDAI","productModel":"SONATA","manufacturer":"Hyundai Motor America"}]}]}
