2019 Chev 3500HD L5P Shutting Off

[Pedro DeLeon Jr]

I have a 2019 Chev 3500HD Diesel L5P that I bought new a few months ago.  I'm starting to have an issue where the engine just shuts off completely with no warning at all.  There's no engine light on when I restart it.  So far I have about 20K miles on it.  Has anyone else had this issue before?

This is after a key start?

When going down the road?

It has happen to me while sitting at a Stop or Stop Light.  The instant I release the brake and apply the gas pedal it just shuts off completely.

There can still be codes, even if the CEL remains off.  But anyway, sounds like it's time to drive to the dealer....

I know it was a while ago  I had a 2014 that did this. After several retries corrective action the Tech found a bad power cable  termination on tie main jumper between the fuse boxes under the hood. Right where the cable was crimped the copper was not crimped, only the insulation was crimped.

I'll let my Service Rep know at the dealer where I have it now.  My truck has been with them since last Monday.  Chances are I might be able to pick it up today.  According to him they also had some GM Tech's looking at it as well besides their own techs.

What was the end result? What did they find?
