My 2015 is in service right now for this very issue, along with with a check engine light and a warning 'Drivetrain: Vehicle cannot be restarted.' They claim it is a failing 12V battery causing the issues. The messages have appeared a couple times since I purchased the car 3 months ago and restarting it had always cleared them.
I'm slightly skeptical of the diagnosis, but I'm willing to give it a shot. What is annoying me however is that tomorrow marks 3 weeks of the car being in service because the 12V is apparently back ordered.
