    My 2010 prius is sitting in the driveway, mindin' its own business, when the alarm goes off. No traffic, no strong wind, no nothin. I review the security camera and see the lights starting to flash with no passers by, nothin. This happened a few times. Any ideas what going on here?

    Id be more concerned if the egr haven’t been cleaned than an alarm going off randomly!
