Catalytic Converter Theft: Prevention, Replacement, and Smog Check Compliance

Catalytic converter theft is on the rise due to the high value of the rare metals they contain. These essential emissions control devices are a key component inspected during a Smog Check, so it's important to protect yours. This article will guide you through prevention strategies, what to do if your catalytic converter is stolen, and how to ensure your vehicle passes its next Smog Check.

Why are Catalytic Converters Being Stolen?

Catalytic converters contain precious metals like platinum, palladium, and rhodium. These metals facilitate a chemical reaction that converts harmful pollutants from your car's exhaust into less harmful substances. The high recycle value of these metals makes catalytic converter theft a lucrative crime. Thieves can quickly remove a converter in minutes, leaving you with a costly repair bill.

How to Protect Your Catalytic Converter

Here are several steps you can take to deter catalytic converter theft:

• Install a theft prevention device: A licensed auto shop can install a protective plate, shield, clamp, cage, or strap to secure your catalytic converter. Ensure proper installation to avoid damage and keep identifying information visible. Avoid welding directly to the converter.
• Mark your catalytic converter: Engrave or etch your Vehicle Identification Number (VIN) or license plate number onto the converter. This can deter theft and help identify the owner if stolen. Consider using bright, fluorescent paint, but avoid covering any identifying information. Check with local law enforcement for free engraving events.
• Adjust your vehicle's alarm: Calibrate your car alarm to detect vibration, alerting you to potential theft.
• Park smart: Park in a garage whenever possible. If parking in a driveway, install motion-sensitive lights. In public lots, park near building entrances or in well-lit, high-traffic areas.

Catalytic Converter Theft Prevention Devices and Smog Checks

A catalytic converter theft prevention device should not negatively impact your Smog Check results. However, your vehicle will fail the inspection if the device:

• Modifies or damages the catalytic converter.
• Obscures any required identifying information.
• Is welded or attached directly to the catalytic converter.

To ensure proper installation, always visit a licensed auto shop.

What to Do if Your Catalytic Converter is Stolen

If your catalytic converter is stolen, take these steps:

1. Visit a Licensed Smog Check Station: Have a replacement converter installed by a licensed Smog Check station.
2. Choose the Right Replacement: The replacement converter must be either an Original Equipment Manufacturer (OEM) part or a California Air Resources Board (CARB) approved aftermarket converter with an Executive Order (EO) number that matches your vehicle's specifications.
3. Timely Replacement: Install the replacement converter as soon as possible to prevent further vehicle damage and to ensure compliance for your next Smog Check. Contact the Smog Check Referee for assistance if the part is back-ordered.

Insurance Coverage for Catalytic Converter Replacement

Check with your insurance provider to see if your policy covers stolen auto parts. Note that the Consumer Assistance Program does not cover the replacement of stolen catalytic converters.
