Proton X70 owners have occasionally reported experiences that could feel like a loss of power o r underpowered performance, especially if the car’s systems enter a protective mode o r if incorrect fuel quality is used. Some international discussions note that factors such as electronic sensor issues, emissions sensor faults, o r engine protection activating can make the SUV feel less responsive — and in some cases, warning lights like engine o r emission failure can appear and accompany power interruption. Regular scanning of diagnostic trouble codes DTCs with an OBD-II tool helps pinpoint the root cause when this happens. Proper scheduled maintenance including checking oxygen sensors and other engine sensors also helps prevent these kinds of incidents.
