Alarm Randomly Going Off

[raytay0825]

2018 GMC Yukon XL Denali alarm randomly going off with vehicle locked. Does not happen when left unlocked. Tailgate latch switch replaced by dealership. Didn’t fix. Question is, is this recorded in the computer system where I could access and determine what sensor is possibly causing this issue?

Welcome to the forum from Virginia. This one is out of my league but several folks have dealt with this and will chime in.
