While stopped in traffic with the vehicle’s automatic engine start-stop feature engaged, the vehicle failed to respond when the accelerator was pressed. The engine had shut off normally due to the start-stop system, but when attempting to move again, the vehicle did not accelerate and appeared temporarily disabled. A “Gearbox fault detected” warning message was displayed. In other occurrences, a “Charging system fault detected” warning appeared immediately after restart. The vehicle required an ignition cycle (turning the vehicle off and back on) to regain normal operation. This condition has occurred on multiple occasions over the past year, including recently, and is intermittent and difficult to reproduce on demand. This condition creates a safety risk because the vehicle can become temporarily immobilized in active traffic, including at stoplights and intersections, leaving the driver unable to proceed as expected. The vehicle has been inspected multiple times by authorized Land Rover dealers for related electrical and charging system issues. Components such as the battery have previously been replaced, but the condition has continued to occur. At this time, the issue has not been consistently reproduced by the dealer. Warning messages associated with the incidents include “Gearbox fault detected” and “Charging system fault detected.” These warnings typically appear during or immediately after an automatic engine restart event. The vehicle remains available for inspection.
