Can I drive with restricted performance?

In Malaysia, if your vehicle experiences performance limitations such as reduced engine power, illuminated warning lights, or restricted output from the electronic system, It is best to undergo a professional inspection immediately to ensure driving safety. Performance limitations can be caused by various factors, including sensor malfunctions, fuel system issues, or the activation of the Electronic Control Unit (ECU) self-protection mechanism. Continuing to drive may lead to more severe mechanical damage or safety hazards. While some vehicles can still travel short distances at low speeds to a repair shop in performance-limited mode, prolonged neglect of this condition may affect engine longevity and increase maintenance costs. For instance, if a turbocharged vehicle enters protection mode due to air intake or cooling system issues, continued operation could result in repair expenses amounting to thousands of ringgit. It is also recommended to prioritize diagnosis at OEM-authorised or certified repair centers to ensure accurate fault code interpretation and restoration of the vehicle's optimal performance.
