Hello, just acquired a 2013 Equinox from my parents. Me son is driving it, he says the alarm is going off randomly. Also the message on the dash Theft detected shows. I've googled it and done the reset a few times, it only lasts about a few days and starts again. I've also cleaned all the contacts on the doors and hood per google. Replaced fuses, replaced key fob batteries, still only lasts a few days and starts alarming again. asked Dealership about it, they have no idea. Anyone here have the same problem and a fix? Thanks in advance
