I have a 2015 Silverado 1500 LTZ and for the last 2 weeks occasionally under gard acceleration I will hear the door locks lock and unlock on their own and will experience a temporary loss of power steering then the ship will right itself on its own. Also hitting an occasional bump in the road the Bluetooth will become inoperable, sometimes in the middle of a call yet the call is still active on my display, the radio screen will go black, sometimes the airbag stabilitrak and ABS lights will go on and stay on until I turn the truck off for 10 minutes. Been to the dealer twice and still no joy telling me there's nothing wrong. At my wits end I've religiously maintained this vehicle and GM and their dealers have hung many of us out to dry. Any ideas
