Reaching out to see if anyone else has experienced this. I have a 2014 GMC Sierra 1500 All Terrain with the 5.3. I’m having problems with starting this thing from time to time. It will run fine for a few days and fire right up every time I get in it. However some days on a cold start or after driving awhile and stopping, when I get in to start it up I got all dash lights are working, except I notice my MPG history is erased (which tells me we’re in trouble) then I get messages on the dash that reads, service trailer brake system, service stabilitrac, power steering reduced. Then the check engine light will appear. When I try to crank everything goes black and I’m not hearing clicks from the engine. After I let it set for about 5 minutes it will fire right up no hesitation. I run the codes on it and there’s is a laundry list of codes, which the GMC dealership is saying they’re all low voltage codes...so we swap the battery truck, it runs fine for about a week and a half and then starts doing the same thing. Alternator is ok because I can see it recharging the amps on the truck....any ideas as to why might cause all this? I’m desparate!!!
