What happened? Starting in October 2020, my 2019 Jaguar F-Type experienced persistent electrical and fuel injector system failures affecting cylinders 1 and 5, resulting in multiple engine misfires and reduced engine performance. The vehicleas fuel injector connectors, specifically connector C1E121A, had misaligned pins causing injector circuit faults (DTC codes P0262, P0274) and frequent misfire codes (P0301, P0305, P0300). These defects caused the vehicle to run roughly and unpredictably, creating a safety risk by compromising engine power and potentially causing loss of control, especially during startup and acceleration. Warning lights and engine fault codes were present throughout the issue. Jaguar dealerships confirmed the problem multiple times through diagnostic testing and extensive inspections, including wiring tests, fuel system checks, and control module evaluations. Despite repeated repairs, including connector reseating and injector replacements during the powertrain warranty period, the defect was never permanently fixed. The vehicle was out of service for over 6 months from August 2021 to April 2022 due to attempts to resolve the problem. After the warranty expired, the same symptoms and fault codes recurred. The dealer diagnosed that the engine must be completely replaced due to persistent injector circuit failures, with an estimated repair cost of $33,000. This ongoing defect severely affects the vehicleas reliability and safety. The problem and its cause have been confirmed by multiple authorized dealers and Jaguar North America.
