Catalytic Converter Theft: How to Protect Your Car in 2026

Catalytic converter theft has surged over 1,000% since 2019 according to the National Insurance Crime Bureau. A thief with a reciprocating saw can steal your catalytic converter in under two minutes — leaving you with a $2,000+ repair bill.

Here’s exactly how to protect your car in 2026, which vehicles are most at risk, and what to do if yours is stolen.

Why Thieves Target Catalytic Converters

Catalytic converters contain platinum, palladium, and rhodium — precious metals worth thousands of dollars per ounce on the commodity market. Thieves sell stolen converters to scrap metal dealers for $50-$1,500 each. According to NICB data, hybrid vehicles like the Toyota Prius are prime targets because their converters contain more precious metal than conventional gas engines.

Most Targeted Vehicles

• Toyota Prius (all years) — highest precious metal content

• Honda CRV and Accord — frequently targeted in urban areas
• Chevrolet Equinox and Silverado

6 Ways to Protect Your Catalytic Converter

1. Install an Anti-Theft Shield

Purpose-built devices like the MillerCAT, CatStrap, or Cat Security shields bolt onto your vehicle and cover the converter with hardened steel. These require extra time and tools to defeat, deterring most opportunistic thieves. Cost: $150-$400 installed — far less than the catalytic converter replacement cost.

2. Park in Well-Lit, High-Traffic Areas

Thieves prefer dark, isolated spots. Park in a garage, under security cameras, or in busy public lots. Avoid leaving your car in the same unmonitored spot for extended periods.

3. Etch Your VIN on the Converter

A visible VIN makes stolen converters harder to sell. Scrap dealers face legal penalties for buying marked parts. Many police departments offer free VIN etching events.

4. Use a Tilt-Sensor Alarm

Standard car alarms don’t trigger when someone slides under your car. A tilt or motion sensor alarm detects movement during a converter removal attempt. Many aftermarket security systems include this feature.

5. Apply High-Visibility Paint

High-temperature paint marked on the converter housing signals to scrap dealers that the part may be stolen. Some local police departments offer free paint marking programs.

6. Install a Dashcam With Parking Mode

Parking-mode dashcams record incidents when your car is off and can send motion alerts to your phone. This provides evidence for insurance claims even when deterrence fails.

What to Do If Your Catalytic Converter Is Stolen

2. Contact your insurance provider — comprehensive coverage typically covers theft
3. Get a repair estimate — see our exhaust repair cost guide for context
4. Ask about OEM vs. aftermarket replacement options
