      2015 GMC Terrain SLT, FWD Immediately after unlocking with the key FOB there is absolutely no power anywhere. Even the odometer display doesn’t light up when opening the door. This has also happened after driving and then turning off the car i can’t lock the doors anymore with the key FOB. In both cases power is restored after a couple minutes without any interference from me. Almost like it was on a timer. This has only happened 3-4 times in the last month. Other symptoms while driving i’ve noticed is random error messages about “service stabilitrak” once. Another time it was as different message. All seem to be random. One time when on cruise control i pressed the rear defrost and the car tried to shut off. Is there a way to diagnose this without sending it to a dealer? I’m a former mechanic i just may not have the right scan tool for this. Thanks in advance.
