2019 Sierra Denali 6.2L sometimes starts, shuts off randomly while driving

[JamesWalker]

2019 Sierra Denali 6.2L sometimes starts, other times it will hit the starter very briefly, stops and no start.. 

 

While driving, the truck will shut off randomly - highway speed, at a light, driving along.  Sometimes it restarts, sometimes not. 

 

No MIL, No codes.  Battery tests 900 CCA, 14v.

Have you ever changed the remote battery?

[JamesWalker]

Yes, still not working

Dealer time. I sure wouldn't hope that it'll fix itself. 

[JamesWalker]

Yes - to the dealer yesterday.  Scanned, codes cleared and changed the batteries in the remotes and reprogrammed them.  $450 for the scan and batteries. 

 

Driving it home, it quit 3 times.   This morning wouldn't start.  Dealer wants me to pay for the tow back to the shop. 

 

[34,000 miles - rear brakes done twice, front brakes once, new battery ]

 

Then the dealer decides that maybe I need a new starter.  And they can throw one in for $900.  I asked how a bad starter would cause the truck to stop while driving?????

 

I would appreciate any advice !

Next dealer is another 50 miles.  I called them and they asked me what a Technical Service Bulletin was??? .... That doesn't give me much faith in their abilities.
