Land Rover Range Rover multiple electrical faults causing restricted driving performance on Land Rover Range Rover

Some Land Rover Range Rover owners report experiencing restricted driving performance due to multiple electrical faults, which often trigger the "Restricted Performance" message and cause the vehicle to enter limp mode, limiting acceleration. Common issues leading to this alert include electrical problems, engine misfiring, transmission issues, and software malfunctions. Owners have noted that ignition coil failures can result in symptoms such as engine misfires and power loss. Signs of restricted performance may manifest as reduced power, poor acceleration, decreased fuel efficiency, and the illumination of the check engine light. Additionally, some owners find that the restricted performance mode may not activate even with known issues like air suspension faults or faulty electrics. This security measure is typically engaged when the vehicle's computer detects significant engine abnormalities or faults, potentially linked to transmission issues or low oil levels. It is advisable for owners to consult a mechanic promptly if the vehicle is in limp mode to prevent further damage, as mechanics can utilize OBD scanner tools to diagnose and address the underlying problems.
