Can you provide information on common issues with the catalytic converters in the 2014 Chevrolet Cruze?

There are a variety of issues that have been reported with the catalytic converter in the 2014 Chevy Cruze. The most frequently encountered problem is a faulty oxygen sensor, which can trigger a P0420 trouble code indicating an issue with the catalytic converter. However, this doesn't typically cause a decrease in performance as it is just the sensor that needs to be replaced. Another commonly reported issue is an exhaust leak, which is more serious because it can potentially lead to damage to exhaust valves, affect the EGR valve function, disrupt the oxygen sensor, and result in complete catalytic converter failure. A significant problem to watch out for is a clogged system, where coolant, oil, or other contaminants can enter the exhaust if there are engine issues upstream. This can result in damage to the catalytic converter. If you experience total catalytic converter failure and need to have it replaced, the cost typically ranges from $990 to $1,020 for parts and labor in this specific vehicle.
