Land Rover LR4 shuts down immediately when pressing brake or accelerator on Land Rover LR4

Some Land Rover LR4 owners report experiencing sudden shutdowns when pressing the brake or accelerator, which may be linked to several factors. These issues could stem from a failing fuel system, such as a malfunctioning fuel pump or clogged fuel filter, leading to a complete loss of power. Additionally, some owners note that the shutdown might be a protective measure for the turbo, emphasizing the importance of allowing the vehicle to idle after high-speed driving to cool the turbo bearings. Furthermore, problems with the air suspension system, such as issues with the rear air bellow or sensors, may also contribute to this shutdown behavior. It is recommended that owners have their vehicles inspected by a qualified mechanic to accurately diagnose and address the underlying issues.
