My 2025 GMC Yukon AT4 Ultimate (VIN [XXX]) has started its engine by itself at least three times when nobody commanded a start. Two of those unattended starts happened while the vehicle was parked in a closed residential garage, which creates a serious carbon monoxide risk to people in the home. I now park it outdoors until the cause is found. The most recent incident was XXX at 7:08 a.m. Central time. Occupants were asleep and nobody started it; both key fobs were accounted for. The myGMC app history shows a successful remote Start at 07:08 AM that none of us sent, followed by two failed Stop attempts at 07:21 AM ("Yukon not responding. Use key to start manually and restore connection."), which I sent after learning it was running. I reported this to OnStar (case XXX) on XXX. OnStar said it could see multiple start attempts persisted through the app but could not see which device or account sent them. The case was escalated to GM's senior technicians, who were unable to trace the source of the start commands. A GM call on XXX was dismissive and did not resolve the issue. The vehicle can still start remotely with no explanation of where the commands come from. Dealer: Royal Buick GMC, Vestavia Hills, AL.
