How to prevent catalytic converter theft on a Toyota Tundra

Protecting your Tundra from catalytic converter thieves is fairly simple to do, but you will want to act now because Toyota Tundra owners are experiencing catalytic converter theft at an alarming rate.

According to, The average cost for a Toyota Tundra catalytic converter replacement is between $3,721 and $3,746. This makes it one of the most expensive vehicles to repair and is sought after by thieves.

Add to the fact that most Tundras have four catalytic converters, two in the front and two in the back, the total cost to replace them can be even higher, and upwards of $6000 to $7000 dollars.

And to make matters worse, it is not uncommon for repair shops and Tundra owners to wait 1-4 months to get replacement catalytic converters from Toyota and other manufacturers due to supply chain issues.

Why is the Toyota Tundra popular with catalytic converter thieves?

The Toyota Tundra, like many SUVs, is a popular target because its catalytic converters are easy to access. The Tundra has high ground clearance so thieves can easily slide under the vehicle and cut the catalytic converter out. An experienced catalytic converter thief can cut one out in as little as 30 seconds with a battery-powered saw.

Another reason the Tundra is a popular target for catalytic converter thieves is that Toyota is well known for using higher amounts of precious metals, such as Platinum, Rhodium, and Palladium in their catalytic converters for low vehicle exhaust emissions purposes. These metals act as catalysts to convert harmful gases like carbon monoxide into less harmful gases like carbon dioxide and water.

Park in a secure garage or lot if possible

Parking in a closed garage or secure parking lot is ideal, but that is not always possible. Thefts don’t always occur at night either. Most thefts occur in mere minutes so large parking lots like those found at businesses and malls make attractive targets because thieves can find many popular vehicles.

Install catalytic converter theft shields

The next best way to deter catalytic converter thieves is to install a catalytic converter shield, sometimes known as a catalytic converter lock or catalytic converter cover.

While it is a disadvantage that the Tundra is high on the list of popular vehicles for catalytic converter theft, the good news is the Toyota Tundra has custom-fit catalytic converter shields you can buy to protect your truck.

Because they are a custom fit for your Toyota, they are easy to install, and most can be installed in an hour or two.
