Catalytic converters contain platinum, palladium and rhodium, and a thief can saw one off in minutes, so they are a common target, especially on hybrids and higher-clearance vehicles. Comprehensive coverage usually pays the repair minus your deductible; with liability-only coverage you pay yourself. File a police report first, then the claim.
Which coverage pays
Comprehensive covers stolen parts; liability-only does not.
Police report first
Claims usually need a police report number. Take photos and report before repairs.
Check your deductible
Replacement often runs $1,000 to $3,000 or more; with a high deductible a claim may not be worth it.

Why thieves take catalytic converters
The catalytic converter sits in the exhaust system and cleans emissions. The platinum, palladium and rhodium inside are valuable to recyclers. It is under the car, so a thief can cut it out in minutes without entering the vehicle.
- Hybrids: more precious metal, higher resale
- Trucks and SUVs: easier to reach underneath
- Cars parked long hours on the street or in open lots
- A loud roar when you start the car
- Check-engine light
- A cut exhaust pipe under the car
Which coverage pays
Stolen parts are a non-collision loss covered by comprehensive: the insurer pays the repair and you pay the deductible. With liability-only coverage, damage to your own car is not covered. If you have rental reimbursement, rental costs during the repair are usually covered up to your limits.
Since 2023 California has limited who can sell used catalytic converters to recyclers: dismantlers, repair dealers, or people who can document lawful ownership, with records of the source vehicle. That makes stolen converters harder to sell, but theft still happens, so prevention and coverage still matter.
What to do after a theft
Don't keep driving it
The car is loud and out of emissions compliance. Tow it or drive only to the nearest shop.
Take photos
Photograph the cut area and where the car was parked; note camera footage times if any.
File a police report
Report to local police (many cities take online reports) and keep the report number.
File the claim
Use your insurer's app, website or phone line for a comprehensive claim, with the report number and photos.
Repair
Use the insurer's recommended shop or one you trust, and give them the claim number.
Is a claim worth it?
Replacement usually costs $1,000 to $3,000 with labor, more on some hybrids. If your comprehensive deductible is $1,000 and the estimate is only slightly higher, the claim pays little. Whether it affects your renewal depends on the insurer; a theft is a not-at-fault loss and usually weighs less than a collision claim, but it is not guaranteed to have no effect.
Prevention
- Parking: use a garage if you can; otherwise a well-lit, busy area with cameras.
- Anti-theft shield: a shop can install a metal plate or cage. Some insurers may offer an anti-theft discount; ask.
- Etch your VIN: an etched converter is harder to sell and easier for police to trace.
Frequently asked questions
Does liability-only coverage pay for a stolen catalytic converter?
Generally no. Stolen parts fall under comprehensive; with liability only you pay the repair.
Do I need a police report?
Yes. Claims usually require the report number, and it helps police track thefts.
Will a claim raise my rate?
It depends on the insurer. A theft is a not-at-fault loss and usually weighs less than a collision claim, but no effect is not guaranteed.
Does an anti-theft shield lower my premium?
Some insurers give anti-theft discounts depending on the device; send us the details and we'll check.
