Just purchased a 2004 Mustang GT 40th aneversary edition. Its stock right now including the Alarm. We have a issue with the alarm system randomly going off with no reason to. We took it back to the car lot they said they disconnected the alarm they didnt it still sets and goes off at will. The car starts and runs so far no issues their with the VATS or PATS and no trouble codes any ideas or solutions thankyou
