Why Catalytic Converters Are Stolen and How to Protect Yours

Why catalytic converters are targeted

Catalytic converters are a regular theft target because they contain precious metals used to reduce vehicle emissions. The metals inside—platinum, palladium, and rhodium—are valuable on scrap markets. Because a converter sits along the undercarriage, thieves can remove it quickly from a parked vehicle, making it an opportunistic crime in many situations.

The metals that make them valuable

Platinum, palladium, and rhodium are scarce and expensive. Their resale value helps explain why catalytic converters are attractive to thieves, especially as market prices fluctuate.

The theft profile and risk factors

Thefts are often opportunistic and occur where cars are left unattended, such as public parking lots or on-street parking. Vehicles with easy access to the exhaust system, or in areas with high scrap-metal demand, may be at greater risk. Thoroughly secured or monitored locations tend to experience fewer incidents.

Protecting your vehicle from theft

• Park in well-lit, high-traffic areas or in a garage when possible.
• Install visible deterrents such as anti-theft devices, shields, or locking clamps designed for catalytic converters.
• Have the converter etched with the vehicle VIN or a unique identifier and keep a photo for records.
• Consider alarms or motion-activated undercarriage guards to deter quick removals.
• If you can, choose parking in a monitored lot or with security cameras.
• Regularly inspect under the vehicle for signs of tampering and listen for unusual sounds that may indicate exhaust issues.

What to do if your catalytic converter is stolen

• Contact local police to file a report. This documentation helps with insurance and replacement processes.
• Do not drive the vehicle if you notice exhaust damage or fumes; arrange safe transport to a repair facility.
• Inform your insurer and follow their guidance for a claim. Replacement parts should be sourced through authorized automotive services.
• Keep records of the theft report, vehicle details, and any quotes for replacement parts.
