On February 25, 2026 By newsroom Topic: Automotive

Valuable Materials: Contain platinum, palladium, and rhodium (worth thousands of dollars per ounce).
Ease of Theft: Easily removed using simple tools, especially from higher vehicles like trucks.
High Demand: Precious metals are sold to scrap dealers for profit.

Trucks and SUVs: Higher clearance makes converters easier to access.
Toyota Prius: Popular target due to having two converters.
Street-Parked or Unattended Vehicles: More vulnerable, especially overnight.

Install Anti-Theft Devices:
- Steel plates or cages around the converter to make removal difficult.
- Alarms (vehicle-wide or converter-specific) to deter thieves.
- Consult a mechanic for the best solution for your vehicle.
Secure Parking:
- Park in a locked garage or well-lit, high-traffic area.
- Install motion sensor lights if parking in a driveway.
Engrave the VIN or License Plate Number:
- Makes stolen converters easier to trace, discouraging theft.

Report to Authorities: Helps with tracking trends and passing stricter laws.
Insurance Coverage:
- Comprehensive policies often cover theft but may require a deductible.
- Evaluate whether the repair cost justifies filing a claim.

Some states require scrap dealers to verify vehicle titles before purchasing converters.
Proposals for stricter laws continue to emerge to deter illegal sales.

Replacement Costs: $1,500–$3,000 depending on the vehicle.
Insurance Considerations: Comprehensive insurance required; delays in parts and repairs may still be a challenge.

Theft prevention methods are often less costly and inconvenient than replacing a stolen catalytic converter.
Proactive steps can save time, money, and frustration.
