Thieves are specifically targeting 2004-2009 Prius, though model years up to 2015 have experienced increased theft of the catalytic converter.
Other things you can do
Park inside a garage or a well lit area. On a busy street not on a side street.
We are researching wifi battery-powered inclinometers that will potentially be able to notify you when your car gets jacked up as this is happening, the factory alarm does not go off.
Be sure if this happens or you hear about it happening to file a police report online. If they cant track it there will never be anything done as nobody in law enforcement knows about it. https://www.portlandoregon.gov/police/cor/
Install a catalytic converter theft prevention device like the steel plate above
If you see this happening to your car, don't potentially get yourself into a confrontation, just call 911 and don't alert the thief that you see them.
Spread the word to every Prius owner you know (feel free to forward this email)
The Prius emissions control system uses a something called a catalytic converter which contains palladium, an extremely valuable metal. As such, the converter has become a target for thieves, and much more so in recent months.
