Thieves target catalytic converters because they contain precious metals such as platinum, palladium and rhodium, which can be sold to scrap metal dealers for a quick profit.

Good news: According to the CBC, catalytic converter thefts are dropping due to declining metal prices. However, as that report mentions, if metal prices increase again, we may see another surge in thefts. Moreover, a decrease in incidents doesn’t mean no incidents, so owners should still take steps to protect vehicles from the hassle and expense of replacing a stolen catalytic converter.

Key takeaways

  • Catalytic converter thefts may be declining, but staying informed on how to protect your vehicle is still a smart and proactive measure.
  • Loud noise from your vehicle is a clear sign your catalytic converter has been stolen. If this happens, contact a tow truck immediately. Do not drive to a garage.
  • You can safeguard your vehicle by taking preventive measures such as installing anti-theft devices and ensuring your insurance policy covers catalytic converter theft.

What is a catalytic converter, and why do thieves target it?

A catalytic converter is an essential part of your vehicle's exhaust system. It helps reduce harmful emissions by converting toxic gases into less harmful substances before they are released into the atmosphere. Unfortunately, the very components that make these converters useful for environmental protection are also what make them attractive to thieves.

Catalytic converters are often easy to steal, as they can be removed from a vehicle in minutes. This quick theft, coupled with the high value of the precious metals they contain, makes them a prime target for criminals. The cost to replace and install a new catalytic converter starts at $1,500 but can skyrocket from there depending on your vehicle’s year, make, model and trim level, according to Driving.ca.

Signs your catalytic converter has been stolen

It will probably be immediately apparent that your catalytic converter has been stolen: Without a converter, your engine is left exhaling through an open, un-muffled pipe. The sound will be a giveaway.

Here are the signs of a stolen converter:

  • Loud exhaust noises: If your car or vehicle suddenly becomes much louder, it could be a sign that the catalytic converter has been removed
  • Check engine light: If this light comes on unexpectedly, it may indicate issues with your car's exhaust system, including a missing converter
  • Reduced performance: A stolen catalytic converter can affect your vehicle’s performance, leading to poor acceleration or stalling
  • Vibrations: Unusual vibrations while driving can also signal problems related to the catalytic converter or exhaust system
  • Strong fumes or unusual smells: If your catalytic converter is missing, you may notice strong exhaust fumes or strange smells, as the vehicle’s exhaust system is no longer filtering harmful emissions properly

Pro-tip: Resist the urge to drive to the nearest garage

According to Brian Turner of Driving.ca, if you suspect your catalytic converter has been stolen, avoid driving your vehicle to the nearest garage. Without the converter in place, parts of your exhaust system may be loose, risking further damage if they scrape against the road. Additionally, running the engine in this condition can cause issues with fuel injection and lead to expensive valve damage.

Your best move is to call a tow truck followed by your insurance provider and local police to report the theft.

Five steps to help prevent catalytic converter theft

Taking proactive steps can significantly reduce the risk of catalytic converter theft. Here are several strategies to consider:

1. Park in secure, well-lit areas

Always try to park your vehicle in well-lit, populated areas. If possible, use a locked garage or a secure parking lot with surveillance cameras. Parking in these areas not only makes it difficult for thieves to operate unnoticed but also discourages potential theft.

2. Install a car alarm with vibration sensors

Equipping your vehicle with a car alarm that has vibration sensors can also help prevent theft. These alarms will alert you if your vehicle is tampered with, including attempts to remove the catalytic converter. Many modern alarm systems offer smartphone alerts, allowing you to monitor your vehicle even when you're not nearby.

3. Etch your VIN on the catalytic converter

Some local police departments offer free VIN engraving programs. Engraving your vehicle identification number (VIN) on your catalytic converter can deter thieves and makes it more challenging for them to sell the converter to scrap metal dealers if it can be traced back to the original vehicle.

For example, in 2023, Surrey RCMP and partners launched a “You Etch It. We Catch It” program. Check local resources to see if there are similar programs near you.

4. Paint your catalytic converter

Another method to deter catalytic converter theft is to paint your converter with a bright, high-temperature paint. This can make the part less appealing to potential thieves and scrap metal dealers. Additionally, it’s a visible deterrent, signaling to thieves that the part is marked and traceable. Seek professional help to paint your catalytic converter.

5. Explore other anti-theft devices

Consider investing in an anti-theft device specifically designed for catalytic converters. These devices can include:

  • Catalytic converter locks: These metal locks are designed to secure the converter in place, making it harder for thieves to remove.
  • Steel cables: Wrap steel cables around the catalytic converter and attach them to your vehicle’s frame. This can serve as an additional barrier against theft.

You will need to evaluate the pros and cons of these devices before investing, and as always - seek professional help with installation.
