Suzuki Grand Vitara emission problems preventing test pass on Suzuki Grand Vitara

Some Suzuki Grand Vitara owners report experiencing emission problems that prevent their vehicles from passing tests, often related to issues with the emission control systems, such as the oxygen sensor or the catalyst. Despite efforts like performing drive cycles and seeking professional checks, some owners find that the emissions system still shows as "not ready," indicating unresolved issues. It is crucial for owners to address these emission problems promptly to ensure compliance with regulations and maintain vehicle performance and efficiency.
