On the 2004-2025 Toyota Prius, the Toyota Prius is the single most targeted vehicle for catalytic converter theft in the United States. The Prius catalytic converter contains higher concentrations of precious metals (palladium, rhodium, platinum) than most vehicles because the hybrid system results in a cleaner-running engine that preserves the catalyst metals. The converter is also easily accessible under the vehicle and can be cut out with a battery-powered reciprocating saw in under 60 seconds. Thieves sell stolen converters for $100-$300 to recyclers who extract metals worth $500+. Gen 2 (2004-2009) and Gen 3 (2010-2015) Prius are the most targeted.
Install a catalytic converter anti-theft shield or cage ($150-$400 installed). Popular options include CatClamp, MillerCAT, and CatShield. These devices make the converter much harder and more time-consuming to steal. Park in well-lit areas and garages when possible. Engrave your VIN on the converter ($30-$50 at a muffler shop) to aid in recovery. Some owners install motion-activated alarms or cameras. If your converter is stolen, replacement costs $1,500-$3,000 for an OEM converter, or $500-$1,000 for an aftermarket CARB-compliant unit (required in California).

On the 2004-2025 Toyota Prius, the 12V auxiliary battery in the Prius is critical for powering the vehicle computer systems that must boot up before the hybrid system can start. Unlike conventional cars where a weak battery can still crank the engine, a dead 12V battery in the Prius means the vehicle will not start at all — no dashboard lights, no READY mode, nothing. The small 12V battery (typically a Group S46B24R) drains faster than in conventional vehicles because it powers always-on systems like the smart key receiver, security system, and clock. The battery typically lasts only 3-5 years, shorter than in conventional vehicles.
Replace the 12V auxiliary battery every 4-5 years as preventive maintenance. The battery is located in the right rear of the cargo area (not under the hood). OEM Toyota replacement costs $200-$300 installed at the dealer. Aftermarket AGM batteries (Optima Yellow Top, Odyssey) run $150-$250 and can be installed DIY in 15 minutes. If the battery dies, a jump start to the 12V terminal under the hood (or in the fuse box on Gen 4) will get the car started. Consider a battery tender/maintainer if the car sits for more than a week at a time.
