Catalytic Converter Stolen in Washington State: What to Do Next [2026]
Do not drive the car. Without a catalytic converter, toxic exhaust gases can enter the cabin. Call your local police non-emergency line and file a report — you'll need the report number for your insurance claim. If you have comprehensive auto insurance, theft is covered; collision insurance does not cover this. Get a repair estimate before deciding what to do: replacement costs range from $1,300 to $4,000+ depending on your vehicle. If the repair costs more than half what the car is worth, selling may be the smarter financial move.
Washington State ranks among the top five states in the country for catalytic converter theft insurance claims — alongside California, Texas, Pennsylvania, and Illinois. In 2026, Bellevue Police alone reported 16 catalytic converter thefts in the first part of the year, up from 14 during the same period in 2025. King County, Pierce County, and Spokane County all see consistent theft activity.
The reason Washington is targeted so heavily: a large concentration of older Toyota Priuses and Camrys — vehicles that carry converters with high concentrations of palladium and rhodium, metals that trade at $800–$1,800+ per troy ounce. A skilled thief with a battery-powered reciprocating saw can cut a converter off a Prius in under 90 seconds.
If you walked out to your car this morning and heard a sound like a broken lawn mower — or found a note under your windshield — here's exactly what to do.
5 Immediate Steps After the Theft
Do not drive the car
A missing catalytic converter leaves your exhaust system open to the cabin. Carbon monoxide and other combustion gases can enter the passenger compartment at dangerous levels, especially during slow traffic or idling. Additionally, the missing back-pressure can damage O2 sensors and — on some vehicles — trigger lean-burn conditions that harm the engine. Park it and call for a tow.
Photograph everything before it's touched
Get photos of the undercarriage showing the cut pipe(s), any damaged heat shields, frayed wiring, and the surrounding exhaust area. Take wide shots showing the whole underside and close-ups of the cuts. These photos serve two purposes: your insurance claim, and the police report. Do this before any shop or tow truck driver touches the car.
File a police report — even if you think it won't help
Call your local non-emergency police line (not 911) and report the theft. You need a report number to file an insurance claim. Beyond insurance, your report contributes to the VIN-tracking database that Washington State uses under HB 2153 to intercept stolen converters at scrap dealers. Most police departments in King, Pierce, and Snohomish counties handle cat theft reports by phone or online — you don't need to go to a station.
Contact your insurance company
Call your insurer or file a claim through the app. Have your police report number, VIN, and photos ready. If you have comprehensive coverage, catalytic converter theft is covered. If you only carry liability or collision, you are not covered — you'll be paying out of pocket. Most insurers move quickly on cat theft claims since the damage is straightforward to document.
Get the car inspected — not just quoted
Thieves frequently damage more than just the converter: cut O2 sensor wiring, bent heat shields, damaged exhaust pipes, and scratched undercarriage components are common. Have the shop do a full inspection, not just a converter replacement quote. The total repair cost is often $200–$600 higher than the converter alone once all collateral damage is counted.
Insurance Coverage — What It Pays and How to Claim
Comprehensive insurance covers catalytic converter theft
Catalytic converter theft is covered under comprehensive auto insurance. This is the coverage type that protects against events outside your control — theft, fire, hail, falling trees, flooding, and animal strikes. Collision insurance does not cover theft. If you only carry liability, you have no coverage for this loss.
How the claim works:
- Your insurer assigns an adjuster (usually within 1–2 business days)
- The adjuster approves a repair estimate from a licensed shop
- You pay your deductible (typically $250–$1,000 depending on your policy)
- Insurance pays the remaining repair cost directly to the shop
- If collateral damage (O2 sensors, pipes) was also caused by the theft, that's typically included in the same claim
Will my rate go up?
Filing a comprehensive claim for theft generally has a smaller rate impact than a collision claim, since theft is not attributed to driver behavior. In Washington State, a single comprehensive claim typically does not trigger a significant rate increase — but this varies by insurer. Ask your agent directly before filing if you're concerned about rates.
Repair Costs in Washington State by Vehicle Type [2026]
| Vehicle Type | Converter Cost (OEM) | Total Repair Est. | Notes |
|---|---|---|---|
| Standard sedan Civic, Corolla, Mazda3 |
$400–$900 | $1,300–$2,000 | Most commonly stolen; mid-range cost |
| Honda Accord / Camry 2000–2010 models |
$600–$1,100 | $1,500–$2,300 | Older models; high-theft target |
| Truck / SUV F-150, Silverado, Tacoma |
$700–$1,400 | $1,600–$2,800 | High clearance = easier access for thieves |
| Toyota Prius All years; #1 target in WA |
$1,500–$2,800 | $2,500–$4,000 | High palladium content = expensive OEM part |
| Luxury / European BMW, Mercedes, Lexus |
$1,800–$3,500 | $3,000–$5,000+ | Multiple converters common; OEM parts expensive |
These estimates assume OEM replacement parts and Washington State labor rates ($130–$180/hr at most shops in King and Pierce counties). If you're outside the Seattle metro area — Spokane, Yakima, Bellingham — labor rates may run 10–20% lower.
Repair vs. Sell — How to Make the Call
This is the question most people are actually trying to answer. The honest framework:
If your car is worth $8,000 and the repair is $2,200, fixing it and keeping or selling it privately is the better financial path. Insurance makes this even clearer — if you're covered, your out-of-pocket is just the deductible.
A 2008 Prius worth $5,500 facing a $3,800 converter replacement is a clear case. Add any pre-existing mechanical issues and the math tilts hard toward selling. Cash buyers purchase cars without converters and account for it in the offer.
The real question: what is the car worth without the converter?
When you sell to a cash buyer like TOWWO, we factor in the missing catalytic converter, the car's overall condition, mileage, and scrap/parts value. You don't need to fix anything. You don't need to tow it to us — we come to you. For a high-mileage Prius with a $3,500 repair bill and $4,800 in private-party value, the difference between what repair costs and what you'd net selling privately is often only $500–$1,000 — and you avoid months of hassle, another insurance claim, and the risk of additional mechanical issues on an aging car.

HB 2153 — Effective April 1, 2025
Governor Inslee signed HB 2153 into law in 2024. It took effect April 1, 2025 and fundamentally changed how catalytic converters can be bought and sold in Washington State.
- Scrap dealers and recyclers must record the VIN of the vehicle each converter came from and retain those records for three years
- Dealers must mark (etch or stamp) converters before purchase
- A $500 licensing fee per transaction goes to Washington State Patrol to fund dealer inspections
- Knowingly trafficking a stolen converter: up to 5 years in prison and $10,000 fine
- Each violation: minimum $1,000 fine
What this means practically: the underground market for stolen converters in Washington is riskier for thieves than it was before 2025. Buyers who purchase them face serious liability if they can't document the source. This has not eliminated theft — precious metal prices are still high enough to attract risk — but it has slowed the speed at which stolen converters move through the supply chain.
It also means your police report and VIN matter more than ever. When law enforcement stops a dealer suspected of buying stolen converters, they can cross-reference VINs in their records against theft reports. A report with no matching VIN in the database is a report that can't help recover anything.
Most Targeted Vehicles in Washington State
Not all cars are equally at risk. Thieves target vehicles where the converter has high precious metal content (rhodium, palladium, platinum), is accessible without a lift, and can be removed quickly. In Washington, this means:
The Toyota Corolla's emergence as a rising target reflects a pattern seen across the country: as protective shields become more common on Priuses, thieves shift to the next most valuable, least-protected vehicle. If you own a Corolla built between 2005 and 2015 and park outdoors regularly, this trend is worth monitoring.
Prevention: What Actually Works
If your converter was stolen and you're getting it replaced — or if you want to protect a car you still have — here are the measures with the best track record:
- Catalytic converter shield or cage — A steel plate bolted to your undercarriage that covers the converter. Adds 5–10 minutes to the theft time, which is often enough for a thief to give up. Popular options for Prius owners in WA: Cat Security, MillerCAT, and Prius Shield. Cost: $200–$400 installed.
- VIN etching or engraving — Engrave your vehicle's VIN directly onto the converter. Under HB 2153, a converter with a traceable VIN is harder for a dealer to legally buy without documentation. Many WA police departments offer free engraving events. Seattle PD and Bellevue PD have done these in community parking lots.
- Catalytic converter alarm — A vibration-triggered alarm wired to your car's system. Price range: $100–$300. Effective when combined with a shield; less effective alone since cutting takes only seconds.
- Park in well-lit, high-traffic areas — Thieves consistently avoid areas with cameras, foot traffic, and lighting. If you're choosing between a dark corner of a lot and a spot near the entrance under a light, the entrance spot is significantly safer.
- Park inside when possible — Garage parking eliminates the risk almost entirely. If you don't have a garage, some neighborhoods in King County have formed informal "garage share" arrangements through Nextdoor for residents in high-theft areas.
