What’s the Most Stolen Part on a Car? Here’s What to Watch For

When it comes to car theft, most people think of entire vehicles being stolen—but often, it’s not the car itself, but specific parts that thieves are after. While whole-vehicle thefts still happen, opportunistic criminals are increasingly targeting valuable, easily resold components. So, what’s the most stolen item? It might surprise you: catalytic converters top the list.

Why? These small emissions devices contain precious metals like platinum, palladium, and rhodium, which fetch high prices on the black market. Thieves can remove one in minutes using a simple saw, leaving owners with a costly repair. Hybrid vehicles, like the Toyota Prius, are especially vulnerable due to higher metal content.

But converters aren’t the only targets. Tires and wheels remain a prime target—especially if you’ve just upgraded to a flashy set. Batteries, too, are disappearing thanks to the growing value of lead and the ease of removal. Even less obvious items like third-row seats, airbags, and garage door openers are on thieves’ radar. That last one is particularly concerning: if left visible, it can give criminals access not just to your car, but your home.

Then there’s your registration. While not "stolen" in the traditional sense, leaving it in your glovebox makes it easier for someone to clone your identity or resell your vehicle illegally.

So, what can you do? Park in well-lit, secure areas when possible. Install anti-theft devices—like converter shields or wheel locks—and never leave garage openers or registration documents in plain sight. If your car sits unused for long periods, consider a security camera or motion-sensor lighting.

Car part theft is a growing problem, but with a little awareness and preparation, you can stay one step ahead. Because in today’s world, protecting your car means protecting its pieces.
