To determine if the catalytic converter on your 2014 Chevy Silverado or 2014 GMC Sierra is failing, watch for symptoms such as reduced engine performance, poor fuel economy, and a sulfuric or rotten egg smell from the exhaust. The check engine light might illuminate with codes like PO420 or PO430. Additionally, a rattling noise from underneath the vehicle may suggest damaged internal components. A clogged catalytic converter could also make the vehicle feel as if the transmission is slipping, similar to a worn-out clutch in a manual transmission. For a 2015 or 2016 Chevy Suburban catalytic converter, these symptoms are also relevant. It's advisable to have the vehicle inspected by a professional for a definitive diagnosis. Ensure any replacement meets California Legal standards, such as the 987611 catalytic converter designed for models like the 2014-2016 Chevy Silverado, Suburban, Tahoe, and GMC Sierra, Yukon, Yukon XL 1500.
