I recently purchased a 2014 Toyota Tacoma. Just in the past two weeks the panic alarm has been going off randomly throughout all hours of the day and night. There is no rhyme or reason that I can figure out. Sometimes it does it at night, but I’ve had it go off early in the morning three times in a row. I took it to a Toyota dealer and they said they couldn’t diagnose it unless it went off, and naturally it didn’t. So I’m still with a car that is progressively irritating my neighbors. (And yes no one is actually trying to break into it, I’ve been siting right next to it when it has started blaring)
Typically the panic alarm goes off, it runs maybe a 20 second cycle, then shuts off.
