An overheating catalytic converter is a serious issue and can cause engine damage if left unaddressed. The catalytic converter can overheat due to several factors, including engine misfires, excessive fuel consumption, o r a malfunctioning exhaust system.

Signs of an Overheating Catalytic Converter:

Unusual Heat from Under the Vehicle: If you notice unusually high heat coming from the exhaust system o r under the vehicle, it could indicate an overheating catalytic converter.
Strange Odor: A severely overheating converter can produce a burning smell o r a sulfur-like odor, similar to rotten eggs.
Check Engine Light: If the catalytic converter is overheating, the check engine light will likely turn on due to detected issues in the emission control system.
Lack of Power and Performance Issues: Overheating can lead to poor acceleration, rough idling, and even stalling as the exhaust system gets backed up.
Solution:

Have the Engine Checked: Overheating can sometimes be caused by other engine issues, such as an ignition problem o r excessive fuel consumption, so a mechanic should check for misfires o r other issues.
Replace the Converter: If overheating is due to a damaged o r clogged catalytic converter, replacement is necessary.
