Hello all. im new to the Chevy world and i just picked up a 2016 Chevy Silverado 1500, shes a 5.3L V8 and just today i started to get a long cranking to get her to start. it takes a good couple seconds to start her up, sometimes i need to stop cranking and try again to fire her up. It started happening and the headunit had some update going on with it that took a couple hours, i also started to get a "Trailer Break Service" error on the dash. im not getting any CEL or Codes that i know of either. Kinda a great way to start my adventure into the world of Chevy, she doesnt have any Warrenty as shes at 120k Miles and ive had her for a about a month now. Anyone had this issue previously and know what i could be?
Like i stated she will fire up its just taking some time to due to, sometimes i need to crank it twice to due so. All electonics are working once the key gets put in the ignition, she just has a long crank.
