3. Malfunctioning catalytic converter?

The following can cause a catalytic converter to malfunction and even explode:

Overheating: If the engine is running too hot due to a malfunctioning cooling system, a rich fuel mixture, or a misfiring engine, it can cause the catalytic converter to overheat and potentially fail.

Impact damage: If the vehicle runs over a large object on the road or is involved in a collision, the catalytic converter could be damaged or crushed, leading to a potential failure.

Engine misfires: Unburned fuel can enter the catalytic converter and ignite inside, causing excessive heat and pressure that could lead to a failure.

Contaminants: Some substances, such as lead, silicone, or phosphorus, can contaminate the catalytic converter and cause it to fail.

Manufacturing defects: In rare cases, a catalytic converter may have a manufacturing defect that causes it to fail prematurely.
